You can test several legal-workflow ideas before buying another subscription. Start with public or synthetic material, a small task and an expected result you can check.
The useful question is what a free tool helps you do reliably after review. A first draft, a source-linked summary and a court opinion search have different failure modes. Keep an ongoing free tier separate from a time-limited trial or a benefit funded by bar membership.
Claude Free Tier: Test Analysis and Review
Claude offers a free plan with usage limits. Anthropic documents a five-hour session reset and says usable capacity varies with demand and workload. Its web search and page retrieval also consume that allowance. Compare tools on the same permitted inputs and review criteria: issues found, material errors, unsupported claims and correction effort. Long documents can consume more capacity; test the document sizes your workflow needs.

ChatGPT Free Tier: Drafting and Source Search
ChatGPT’s free plan includes web search and support for uploaded files and images. OpenAI documents separate limits for tools such as uploads, data analysis and image creation; check availability and limits in the intended account. For a first test, use a public document or synthetic correspondence and ask for a structured draft or source-linked summary. Check names, dates, quotations and legal propositions against the underlying material before use. Web search locates sources; it does not establish completeness or legal currency.

Google Tools: Gemini, NotebookLM, and Google Scholar
Assess the exact Google service, account terms and connected-app settings separately. Consumer access, Workspace inclusion and precise notebook limits were not confirmed in this update. A product’s presence in an existing account does not establish approval for client information.
For a source-grounded notebook experiment, use a small set of permitted documents and ask questions whose answers you can locate yourself. Open the cited passage and compare the answer with its full context, including qualifications and conflicting statements. Keep missing or uncertain answers visible. Generated summaries and audio can support review, but important conclusions still need checking against the originals.
Google’s current generated-report guidance warns that generated content can contain inaccuracies. The documentation uses Gemini Notebook branding; this update retains the article’s familiar NotebookLM reference without assuming a universal account migration.
Use Google Scholar as one possible public case-search starting point. Verify the opinion, jurisdiction, date and subsequent treatment using authoritative sources. A located opinion or an AI citation is not a complete citator check.

Building a Small Evaluation Workflow
Choose one recurring task and compare preparation, generated output, checking, corrections and final use. For research, begin with a known source packet and record missing or invented authorities. For drafting, use a synthetic example and a reviewer’s acceptance criteria. For document organisation, test whether cited answers preserve meaning and reveal missing material.
Record the mistakes as well as the time. Free access does not remove setup, checking or confidentiality obligations. Do not upload medical records, depositions or matter files before confirming authority, account terms, approved audience and the firm’s data-handling requirements.
Upgrade when testing shows that an alternative meets your requirements and its benefits justify subscription, setup and ongoing review costs. This article has no evidence establishing that a free stack replaces a fixed percentage of enterprise research or contract review.
