TeseFirme
ActiveLegal document verification with multiple AIs
Overview
TeseFirme is a verification layer for legal documents. Before you file a petition, defense, appeal, or legal opinion, you submit the text and three independent AI models check every citation, statute, and line of reasoning. Instead of trusting a single tool's output, TeseFirme relies on consensus across models: if one AI cites a precedent the other two can't find, that reference gets flagged for review.
It doesn't draft or generate the document. It sits on top of whatever workflow you already use — ChatGPT, legal assistants, or manual writing — and returns a report with a confidence score, each AI's verdict per citation, and correction suggestions. In a results panel, every citation gets a color-coded status — confirmed, needs attention, or incorrect — so you can see at a glance what's correct, what needs attention, and what is likely wrong.
Results come back in seconds and can be exported as a report, giving you a record of the diligence done before filing. Access is credit-based with no subscription: you pay per verified document and start with free credits, no card required.
The problem
Lawyers increasingly rely on generative AI to draft filings, but these models hallucinate — they invent case law, cite rulings that don't exist, and attribute decisions to courts that never issued them. A fabricated citation can undermine an argument, weaken the case, and raise professional questions, and checking each reference by hand across Brazil's courts is slow and draining. TeseFirme closes that gap with a systematic check before anything is filed.
Who it's for
- Solo lawyers and small firms who already draft with AI
- Legal teams that need to validate filings before they go out
- Legal professionals using ChatGPT or legal AI assistants day to day
- Firms that want a documented record of citation review

Features
Multi-AI verification
Three independent models cross-check every citation; consensus between them lowers the risk of accepting a reference invented by a single model.
Per-citation analysis
Each reference gets a color-coded status — confirmed, needs attention, or incorrect — and each AI's individual verdict in the results panel.
Confidence score
An overall score sums up how reliable the document is, so you can prioritize what to review before filing.
Exportable report
Export the result as a report — a record of the diligence done before the document is filed.
Complements any tool
Works on filings written in any workflow, from ChatGPT to manual drafting, without replacing what you already use.
Correction suggestions and history
Get suggestions for the flagged points and keep a history of every document you've verified.
