AI Tools for Policy Analysis and Clause Interpretation

Vendor pages document different file, research, privacy, and accuracy constraints, but do not show how an assistant will interpret your policy.

Sources checked 2 Oct 2026

For AI tools for policy analysis and clause interpretation, the vendors document file handling in OpenAI's data analysis guide, Anthropic's file-upload guide, and Google's Gemini file guide, but their pages do not establish that an assistant will interpret a particular clause correctly. Chat Picker has not tested ChatGPT, Claude, or Gemini for this use; under its sourcing method, this page compares published documentation and gives you a repeatable validation method.

What the vendors document

As read on October 1, 2026, OpenAI's ChatGPT Plus page lists Plus at $20 per month, billed monthly; Anthropic's pricing page lists Pro at $20 per month or $17 per month on annual billing with $200 up front; and Google's US plans page lists Google AI Pro at $19.99 per month. These figures do not rank interpretation quality.

ChatGPT: OpenAI says spreadsheets, PDFs, and text or data files can produce answers, tables, or charts, subject to model, plan, workspace, and account settings. As read on October 1, 2026, OpenAI's File Uploads FAQ sets a 512 MB hard limit per file, caps each text or document file at 2M tokens, and limits Free users to 3 uploads per day. Files follow the chat's retention period and are generally deleted within 30 days after chat deletion, subject to stated exceptions. The ChatGPT pricing page offers a training opt-out for Free, Go, Plus, and Pro.
Claude: Anthropic's file guide, read on October 1, 2026, sets a 500 MB limit per chat file and 30 MB per project file. Claude analyzes text and visual elements in PDFs of 100 pages or fewer, but processes text only in PDFs from 101 to 1,000 pages; for non-PDF documents, it extracts text only and cannot interpret embedded images. The Claude pricing page, read on the same date, provides a training opt-out for Free, Pro, and Max and says Team is not trained on by default. These pages do not state a file-deletion period.
Gemini: Google's file guide, read on October 1, 2026, allows up to 10 supported files in a prompt, subject to availability. For a work or school account, a Workspace administrator must enable Gemini access before Drive uploads; adding Drive files also requires Keep Activity and a connected Workspace. The US plans page states no training setting, so Chat Picker marks that comparison cell “Not verified.”

For current-source work, OpenAI says Deep Research can use uploaded files, the public web, specified sites, and enabled apps, with citations or source links in completed outputs. Claude Research is available to paid Pro, Max, Team, and Enterprise users and can search the web and connected internal context. Gemini Deep Research includes Google Search by default, allows it to be deselected, and accepts other selected sources and files.

OpenAI says ChatGPT can be incorrect or misleading and may sound confident when wrong; it recommends verifying quotations, data, and references. Anthropic likewise warns that Claude can produce convincing but ungrounded quotations and should not be the only source of truth. Google says its models are probabilistic and may overgeneralize, while Gemini's Sources panel may expose public websites, uploaded files, and connected Workspace documents or email. A source panel supports checking, but it does not guarantee a correct interpretation.

For legal work, OpenAI's usage policy bars tailored advice requiring a license, including legal advice, without appropriate licensed-professional involvement, and automated high-stakes decisions in sensitive areas without human review. Anthropic's Usage Policy classifies legal interpretation, guidance, and decisions with legal implications as high-risk and requires qualified professional review before finalization. Google's safety page does not state a special legal-interpretation review rule, so this page does not infer one. This article is not legal advice.

What the documentation cannot tell you

The cited documentation cannot tell you whether an assistant will miss a qualifier, invent an exception, preserve conditional language, handle a particular scanned table, or attach a citation that supports only part of a conclusion. It also cannot establish completeness, latency, or workflow cost for your policy. Use the same source, prompt, plan, and review standard, then decide from corrections, source alignment, elapsed time, usage limits, and subscription charges.

How to check it yourself

Separate extraction from summary. Give each assistant this prompt: “Extract every actor, duty, permission, prohibition, condition, exception, and exact source phrase from this policy: Contractors must obtain written approval before sharing confidential material. Contractors may share it with outside advisers bound by confidentiality duties. Any exception requires approval from the legal team. Do not infer terms. Then write a separate summary.” Look for traceability. Record omissions, additions, and unsupported summary terms.
Test recall and ambiguity. Paste the same policy and ask: “List every rule, preserve all qualifiers, quote the text, and mark uncertainty instead of resolving it.” Then provide: “The contractor may disclose confidential material to an adviser whom the contractor reasonably considers qualified.” Ask for each defensible reading, the facts needed to choose, and its supporting text. Look for hidden assumptions; record misses, invented rules, and unresolved ambiguity.
Check impact scoring. Give the same clause set and ask: “Create a review queue from high to low potential consequence. Quote the supporting clause, label each ranking as text or judgment, and list missing facts that could change the order. Do not give legal advice.” Record any reordering that lacks textual support.
Validate sources. Upload the same policy and ask: “For every conclusion, give the page or section and a verbatim supporting quote. If the source does not support a conclusion, say so instead of filling the gap.” Open every cited location. Record missing conditions, partial support, and contradictions.
Compare like with like and keep a human gate. Run identical prompts in ChatGPT, Claude, and Gemini. Record the plan, elapsed time, usage-limit messages, checkout subscription charge, and reviewer corrections against the source. Compare only the same task, and require source review, qualified legal judgment where needed, and final approval before use.

Which rows of the comparison matter

Open the ChatGPT, Claude, and Gemini comparison matrix. Read the rows for Free plan, Low-cost tier, Main paid plan, Heavy-use plans, Team plan, Context window in the app, How usage limits are described, Training on your chats, and Ads. For clause work, give particular attention to context, upload and research limits, training controls, and plan access. A context figure is not extraction accuracy, and “Not verified” does not mean zero. Under its method, Chat Picker leaves unconfirmed vendor figures blank or marked “Not verified”; confirm the vendor page before subscribing. This rewrite removes the older page's unsourced statistics and test results.
