Capability · AI-assisted extraction

AI-Powered Scraping Services

Used where it genuinely helps, validated because it can be confidently wrong.

AI-powered scraping uses language models to extract structured fields from pages whose layout varies too much for hand-written rules — long-tail sources, documents, and sites that change often. Actowiz applies it selectively and validates every AI-extracted field deterministically, because an LLM will produce a confident, plausible, wrong value rather than an error.

The industry currently markets AI extraction as strictly better than rules. It is not. It is better at variety and worse at certainty, and the difference matters enormously depending on what you are doing with the data.

Definition

What is AI-powered scraping, and what is it actually better at?

AI-powered scraping uses a language model to read a page and return structured fields, instead of hand-written selectors targeting specific elements. It is genuinely transformative for a particular class of problem, and genuinely worse for another. Being clear about which is which is the whole value of this page.

Where AI extraction is clearly better

Long-tail sources. Two hundred supplier sites each with fifty products and a unique layout. Writing rules for each is uneconomic; a model handles variety natively.
Documents. PDFs, terms sheets, prospectuses and tariff circulars where structure varies per publisher.
Frequently changing layouts. Sites that redesign often break selectors and do not break a model reading semantically.
Unstructured text. Pulling attributes out of a prose description where no field exists.
Cold start. Getting a usable pilot from an unfamiliar source in hours rather than days.

Where hand-written rules remain better

High-volume stable sources. A major retailer's product page is consistent. Rules are faster, far cheaper per page, and deterministic.
Anything requiring exactness. A price feeding a repricing engine should come from a deterministic extraction, not a probabilistic one.
High-frequency collection. Model inference cost per page makes hourly collection at scale prohibitive.
Auditability. A selector's behaviour is inspectable. A model's reasoning is not.

The failure mode that shapes our whole design

A broken selector returns nothing, and nothing is loud — you notice a null. A language model asked for a price it cannot find will frequently return a plausible number that is not on the page. That is quiet, and it enters your dataset looking exactly like data.

This is why every AI-extracted field is validated: checked for type and range, and critically checked for grounding — does this value actually appear in the source content? Values that fail grounding are rejected and escalated, never delivered with a confidence score and a shrug.

How we use it

Six ways AI is applied in our pipelines

Selectively, always validated, and never as a replacement for rules where rules are better.

Schema

AI extraction fields you receive

Every AI-extracted record carries how it was produced and how it was verified. Without both, you cannot audit the output.

Deliverable schema — AI extraction envelope (v2.4)
Field	Type	What it captures	Refresh
`record_id / source`	string	Record identity and the source it came from	Every record
`method`	enum	rules, llm_extract or hybrid, so extraction provenance is never ambiguous	Every record
`model_pass`	string	Which pass produced the value, such as extract or extract+verify	AI records
`fields`	object	The extracted values in your agreed schema	Every record
`validation`	object	Per-field validation result, including the specific check applied	AI records
`price_in_source / grounded_pct`	boolean / decimal	Whether values were found in the source content, and the share that were	AI records
`confidence`	decimal	Model confidence, delivered but never used alone as an acceptance criterion	AI records
`escalated / escalation_reason`	boolean / string	Whether the record went to human review and why	AI records
`reviewer_decision`	enum	For escalated records, the human outcome: accepted, corrected or rejected	Escalated records
`prompt_version`	string	Which prompt and schema version produced the extraction, for reproducibility	AI records
`cost_class`	enum	Relative inference cost class, so you can see where AI extraction is being spent	AI records

Confidence is delivered but never used alone as an acceptance criterion. Language models are confidently wrong often enough that confidence without a grounding check is not a quality signal.

Use cases

How AI-assisted extraction gets used

Four patterns, with the outcome each is judged on.

Long-tail source coverage

Hundreds of small sources with unique layouts are extracted against one target schema, with grounding validation rejecting values not present in the source and escalating failures to review.

Outcome: Source coverage expanded far beyond what per-source rule-writing would justify economically.

Document extraction with auditable provenance

PDFs and terms documents are extracted with page-level references retained, validated for type and range, and grounded against the document text.

Outcome: Varied documents turned into a comparable dataset where every figure traces to a page.

Self-healing deterministic rules

AI monitors for layout change, proposes new selectors, and regression-tests them against known values, with a human approving before promotion to production.

Outcome: Breakage incidents reduced without handing production extraction to a probabilistic method.

Cold-start pilots on unfamiliar sources

Schema inference and AI extraction produce a usable sample from a new source within hours, before any rule-writing investment is committed.

Outcome: Source viability assessed before engineering effort is spent on it.

Engagement examples

Two engagements, anonymised

Clients rarely permit naming. These are real engagement shapes with identifying detail removed, so you can judge whether the work resembles your situation.

Industrial distributor · DE

Rule-writing could not reach the supplier long tail

Situation

Around two hundred supplier sites each carried a few dozen products with unique layouts, and writing and maintaining a rule per site was uneconomic.

What we ran

LLM extraction against one target schema with grounding validation rejecting values absent from the source, and escalation to review on failure.

Result

Long-tail supplier coverage became viable, with roughly 1% of records escalated rather than shipped unverified.

Procurement team · EU

Model-extracted prices included figures that were not in the documents

Situation

An earlier AI extraction attempt produced plausible prices for documents where no price was stated, and the errors were invisible in the output.

What we ran

Grounding validation searching for every value in the source text, with ungrounded values rejected and page-level references retained.

Result

Fabricated values stopped entering the dataset, and every remaining figure traced to a document page.

Examples are anonymised at client request. Named references are available on request under NDA. See published case studies →

The 24-hour sample — run on your sources, not ours

Before you commit to anything, we run this service against your own sources and send you the output. If the coverage isn't there, the sample will show you that too — which is the point. We would rather lose the deal at the pilot than at month three.

How we engage

Three ways to engage us for this work

Same collection pipeline and same QA underneath. The difference is who holds the schedule and how the data reaches you.

Managed service (most common)

We own the collection, the QA and the delivery. You receive clean data on a schedule and never touch a scraper.

Dedicated engineer assigned to your account
Site changes fixed by us, not reported to you
Scheduled delivery to your warehouse or S3
Named contact on Slack or email

Best fit: Teams who need the data, not the infrastructure.

API access

The same collection pipeline exposed as an authenticated REST endpoint your systems query directly.

On-demand and scheduled endpoints
Rate limits agreed to your load profile
Sandbox keys for integration testing
Versioned schema with deprecation notice

Best fit: Product and engineering teams building on live data.

One-time or project extraction

A defined pull for a specific question — market sizing, diligence, a pitch, a one-off audit.

Fixed scope agreed in writing upfront
Single delivery with full QA report
Methodology documented for your records
Converts to managed if you want continuity

Best fit: Research, strategy and diligence work with a deadline.

Pricing

Every engagement is quoted individually, because the honest answer depends on your scope: how many sources, how many records, how often, and how the data reaches you. We scope it with you, run a free pilot on your own sources, and then quote a fixed monthly figure — no per-request metering and no overage billing when volumes move. Request a quote and you will have a number after one call.

Build vs buy

AI extraction, hand-written rules, or both?

The honest answer is almost always both, with the mix decided per source rather than as a policy.

In-house build vs self-serve tool vs Actowiz managed service
Consideration	In-house scraping team	Generic proxy / DIY tool	Actowiz managed feed
Time to first usable data	6–12 weeks of engineering before anything is trustworthy	Days, but output needs manual cleanup before use	Free pilot in 24 hours, production in 5–10 business days
Who fixes it when a source changes	Your engineers, at the cost of their roadmap	You do — tools report failures, they don't resolve them	We do, same business day, inside the retainer
Data quality assurance	Whatever your team has time to build	None beyond HTTP success	Schema validation plus sampled human QA on every run
Compliance documentation	Rarely produced, then requested urgently by legal	Not provided; terms risk sits with you	Sources, method and lawful basis documented for review
Accountability	Distributed across a team with other priorities	A support ticket queue	A named engineer and an account owner
True annual cost	Engineer salaries, proxies, hosting, ongoing maintenance	Low licence fee plus significant hidden analyst time	One fixed monthly retainer, quoted after scoping

Why we validate grounding rather than trusting confidence

Every AI extraction vendor delivers a confidence score. Very few check whether the extracted value actually appears in the source. That gap is where the category's real risk sits.

The specific problem

Ask a language model for a price on a page that has no price, and a meaningful share of the time it will return a number. Not an error, not a null — a plausible price, formatted correctly, sometimes with high confidence. The model is completing a pattern, and a price-shaped answer is the most probable completion.

This is categorically different from a broken selector. A broken selector returns nothing, and nothing is loud. A fabricated price is quiet, and it looks exactly like every other price in your dataset.

What grounding validation does

Locates the value in the source. Every extracted value is searched for in the source content, with normalisation for formatting.
Rejects ungrounded values. A value not present in the source is not delivered with a low confidence score. It is rejected and the record escalated.
Reports the grounded share. grounded_pct per record tells you how much of the extraction was verifiable.
Adds type and range checks. A price of 4,850,000 for a bearing fails range validation regardless of grounding.
Escalates rather than ships. Failed validation goes to human review. Around 1.2% of records in our runs.

Confidence is still delivered, because it is mildly useful. It is not an acceptance criterion, because a confidently fabricated value scores high. Any vendor whose quality story rests on confidence alone has not thought about this failure mode, or is hoping you have not.

Where we tell clients not to use AI extraction

We sell this capability and we talk clients out of it regularly. Not from modesty — because using it in the wrong place produces worse data at higher cost, and that ends the relationship.

Cases where we recommend rules instead

A single high-volume retailer. One consistent layout, millions of pages. Rules cost a fraction per page and return exact values. AI extraction here is paying more for less certainty.
Prices feeding a repricing engine. A probabilistic extraction in a pricing loop is a bad idea even at 99% accuracy, because the 1% moves real money and you cannot tell which records they are.
High-frequency collection. Hourly extraction across a large catalogue makes per-page inference cost dominate the engagement.
Anything requiring inspectable logic. Where you need to explain to an auditor exactly how a number was derived, a selector is inspectable and a model is not.

What we usually recommend instead

A hybrid, decided per source. Deterministic rules on the stable, high-volume sources where most of your record count lives. AI extraction on the long tail, the documents and the sources that change constantly. Self-healing AI monitoring the rules so breakage is caught and fixed faster.

Every record carries method naming which produced it, so you always know whether a given value came from a deterministic rule or a validated model extraction. That field exists precisely so the hybrid is auditable rather than a black box. For corpus-scale AI work, see AI training data collection.

How it works

How an AI-assisted engagement goes live in 5 to 10 business days

Source mix is assessed first, and we state which sources should use rules rather than AI before quoting.

Scope the sources and fields

You send us target sites, regions, SKUs or keywords. We return a field-level schema proposal, coverage estimate and refresh recommendation — usually within two working days.

Pilot sample, free

We extract a real sample from your actual targets so you can inspect field fill rates, edge cases and match quality before any commitment.

Production build and QA harness

Our engineers build extractors, then wire validation rules: type checks, range checks, duplicate detection and golden-record comparison against a manually verified subset.

Scheduled delivery into your stack

Feeds run at your chosen cadence and land in the warehouse or bucket you already use. Schema changes are versioned and announced before they ship.

Ongoing monitoring and SLA support

We watch coverage drift, fill rates and source changes daily. A named engineer owns your account, and layout breaks are fixed by us — not queued for you.

Formats & destinations

JSON, JSONL, CSV, Parquet or XLSX, delivered to Amazon S3, Google Cloud Storage, Azure Blob, SFTP, Snowflake, BigQuery, Databricks or a REST/GraphQL endpoint. Webhooks fire on completion, and every batch ships with a manifest containing row counts, schema version and QA results so your pipeline can fail loudly instead of silently ingesting a bad file.

Compliance & data ethics

AI-assisted extraction operates on the same publicly-sourced content under the same boundaries as our other services. Extracted values are validated against source content and ungrounded values are rejected rather than delivered. Prompt and schema versions are recorded per record for reproducibility, and escalated records carry the reviewer decision.

Definitions

Terms used on this page

Plain definitions of the terms used on this page, so procurement and legal reviewers are working from the same vocabulary as your data team.

Grounding validation: Checking that an extracted value actually appears in the source content. It is the defence against a language model returning a plausible value that was never on the page.
Confident wrong value: The defining failure mode of LLM extraction. A broken selector returns nothing, which is loud. A model asked for an absent price often returns a plausible number, which is quiet.
Method provenance: A field recording whether a value came from a deterministic rule, an LLM extraction or a hybrid path. It is what makes a mixed pipeline auditable rather than a black box.

FAQ

AI-powered scraping: frequently asked questions

What data, platform and compliance teams ask during evaluation.

No, and this is the industry's most common overclaim. AI is better at variety and worse at certainty. On a stable high-volume source, deterministic rules are cheaper per page, faster and exact.

Where AI wins is the long tail: two hundred supplier sites with unique layouts, documents whose structure varies by publisher, and sites that redesign often. Those are variety problems, and rules do not scale to them economically.

That it returns a plausible wrong value rather than an error. Ask a model for a price on a page with no price and it will frequently produce a correctly formatted number that is not on the page, sometimes with high confidence.

A broken selector returns nothing, and nothing is loud. A fabricated price is quiet and looks like every other price in your dataset. This single failure mode shapes our entire design.

Grounding validation. Every extracted value is searched for in the source content with formatting normalised. A value that is not present is rejected and escalated, not delivered with a low confidence score.

We also apply type and range checks, and report grounded_pct per record. Around 1.2% of records escalate to human review rather than shipping. Confidence is delivered but is never the acceptance criterion, because a confidently fabricated value scores high.

Only where it is the right tool, and we regularly recommend against it. If your requirement is one high-volume retailer, rules are better and we will say so rather than selling the more fashionable option.

Most engagements end up hybrid: rules on the stable high-volume sources where most records live, AI on the long tail and documents. Every record carries a method field so you always know which produced a given value.

Yes, and this is one of the most reliable uses. AI monitors for layout change, proposes candidate selectors, and those are regression-tested against known values before a human approves promotion to production.

Note what that design avoids: it uses AI to maintain deterministic extraction rather than replacing deterministic extraction with AI. Production values still come from inspectable rules.

Per source, often yes. Per page, almost always no. Model inference has a real cost per page that deterministic rules do not, so at high volume and high frequency AI extraction becomes the expensive option.

The economics favour AI when you have many sources with few pages each, and favour rules when you have few sources with many pages. We deliver a cost_class field so you can see where inference spend is going.

Yes, and it is one of the strongest use cases. Document structure varies by publisher in ways that defeat templates, and models handle that variety well.

We retain page-level source references on every extracted figure and apply the same grounding validation, so any number can be traced back to its page. That traceability is usually what makes document extraction usable for compliance and procurement work.

As far as it can be. Every record carries prompt_version and the schema version that produced it, plus the validation results and any reviewer decision.

The honest caveat: language model outputs are not perfectly deterministic even at fixed settings, so re-running an extraction may produce small differences. Grounding validation constrains this to values actually present in the source, which bounds the variation rather than eliminating it. For anything requiring bit-exact reproducibility, rules are the correct choice.

We quote individually. Drivers are source count, page volume per source, document versus page extraction, and how much escalation to human review your accuracy requirement implies.

The economics differ from rules-based work: cost scales with pages processed rather than sources maintained. A long tail of many small sources is where it pays; a single large catalogue is where it does not. One scoping call, a free pilot on your own sources within 24 hours including the validation report, then a fixed monthly quote. Request a quote.
