Brasilia is a documents city: the National Congress, the ministries, the STF and the courts, plus a legal sector that lives on PDFs. In 2026, the triage that used to take an associate a full day takes an AI tool twenty minutes — the skill is deciding where each document goes. The tools below split into cloud assistants (best quality, upload to the vendor) and open-source parsers (self-hosted, data stays with you). Brazilian Portuguese is well supported across the board.

1. NotebookLM — free Upload the whole case file — bills, rulings, contracts, annexes — and ask questions that come back with citations to the exact source passage. Free with a Google account. The citation grounding is what makes it the best first pass for legal and administrative documents.

2. Claude — free tier, Pro ~$20/mo The strongest long-context reader of the frontier models: a 200K+ token window reads roughly 150,000 words in one pass, and PT-BR quality is excellent. Paste or upload the document and ask for a structured summary with the key clauses flagged.

3. ChatGPT — free tier, Plus ~$20/mo File upload, analysis, table extraction and comparisons across multiple documents. The free tier is enough for occasional summarizing; Plus adds longer documents and more uploads.

4. Google Gemini — free tier Deep Google Docs/Drive integration and free PDF processing. If your ministry or firm lives in Google Workspace, Gemini summarizes without leaving the drive.

5. ChatDOC — ~$5-10/mo Purpose-built PDF chat with visible citations, table extraction and a friendly interface. A good middle ground between a general chatbot and a legal-tech platform.

6. docling — open source, 65,720 stars IBM's document parsing library: PDFs, DOCX, scans → clean Markdown/JSON for analysis or RAG pipelines. Self-hosted, so sensitive material never leaves your machine. The right answer when LGPD (Brazil's data protection law) matters — personal data in documents needs controlled handling.

7. unstructured — open source, 15,362 stars The enterprise-grade parser for document workflows. Heavier to set up, but the standard choice when documents flow into internal systems at scale.

Quick comparison: NotebookLM free (citation-grounded Q&A); Claude free/Pro ~$20 (long documents, strong PT-BR); ChatGPT free/Plus ~$20 (multi-document analysis); Gemini free (Workspace integration); ChatDOC ~$5-10/mo (PDF chat, citations); docling free self-hosted (LGPD-safe parsing); unstructured free (enterprise pipelines).

The decision rule for Brasilia professionals: public filings and published rulings — use the cloud tools, they are public anyway. Attorney-client material, medical data, or anything containing personal information — that is where LGPD applies, and where self-hosted docling or an enterprise tier is the defensible choice. And a workflow tip: summarize first, read the summary, then send only the flagged pages to a human reviewer — the AI's job is triage, the lawyer's job is judgment.

❓ FAQ

Is it safe to upload court documents to these tools?

Published rulings and public filings are public anyway — cloud tools are fine. Attorney-client material and personal data fall under LGPD, so use self-hosted docling or an enterprise tier with data-processing agreements.

Which tool handles Brazilian Portuguese best?

The frontier models — Claude, ChatGPT and Gemini — are all strong in PT-BR, including legal and administrative register. Test the tool on your own documents; quality varies by domain.

Can they handle scanned PDFs?

Gemini, ChatGPT and ChatDOC handle scans with built-in OCR, and docling has OCR for self-hosted pipelines. Check the quality on poor scans — handwriting and low resolution still trip up most tools.

Which option is free?

NotebookLM and Gemini free tiers cover a lot of summarizing needs. docling and unstructured are open source and free to self-host — you pay in setup time instead of money.
