Sovereign Legal Intelligence
Legal AI with local processing — PDFs, audio, and hearing transcripts analyzed with exact file and page citations. Built for solo practitioners and elite litigators who cannot afford mistakes.
Locus.IA didn't come from a tech lab. It was designed inside a law firm representing major banks, dealing with highly sensitive data daily.
Law firm partner with 50+ staff, acting for nearly four decades for one of the country's largest financial institutions. When your client is a bank, confidentiality is not optional.
Co-founder is a Notary Public, holding a Master's in Law and a Mensa member. The anti-leak architecture was born from dealing with public trust daily.
Locus.IA doesn't know what files you upload. Your documents stay 100% on your computer. We have no access, we do not store, we do not see. Period.
Already used by professionals who cannot afford mistakes:
We asked ChatGPT itself: "Locus IA vs ChatGPT: which is better for lawyers analyzing confidential documents?"
This was its unedited response.
If your priority is absolute confidentiality and reliable legal document analysis,
local/offline Locus.IA is more suitable.
ChatGPT does not replace a specialized local solution for confidential documents.
Capturas de tela originais sem edição. Consulta realizada em fev/2026 em conta sem histórico prévio sobre o produto.
In less than 2 minutes, understand how it analyzes real documents and generates arguments with citations.
Most generic AIs require you to upload confidential documents to unknown servers. Locus.IA was built by lawyers who understand the real weight of Attorney-Client Privilege.
What happens to your data when using ChatGPT, Gemini, or Claude directly:
Architecture designed for the professional who cannot afford to compromise data:
Total transparency. We don't ask you to trust blindly — we show exactly what happens to every byte of your documents.
PDF reading, image OCR, and semantic indexing happen 100% inside your computer. No original document is transmitted.
Before any request, sensitive entities (names, SSNs, accounts) are replaced by tokens. The reversible dictionary remains encrypted on your machine.
Pseudonymized text is sent via TLS to Enterprise models (DPA). Zero retention. Your data never trains public models.
Need total isolation (Air-Gapped)?
Locus.IA has a 100% Offline On-Premises version with local LLMs for government or highly critical cases.

Not a generic AI adapted to Law. Each feature was designed for the real workflow of those dealing with cases every day.

AI recognizes doc type, date and client and groups everything. uses AI · 1 credit
Every tool runs on your computer and uses no credits. The only exception is Smart folder organization, which uses AI and costs 1 credit per use.
We don't yet offer OCR or PDF-to-Word conversion in the Workshop — the app's AI transcription covers text extraction.
Add a certification stamp with customizable text ("I hereby certify...") on any page of the PDF and, if you wish, digitally sign it with your A1 certificate (.pfx/.p12) in the PAdES standard. It's a real cryptographic signature, verifiable in Brazil's ITI Conformity Verifier (validar.iti.gov.br) — not a pasted image. The private key never leaves your computer.
A3 (token) certificate support coming soon. Locus.IA is the tool that applies the signature; the validity and responsibility for the act of certification rest with the professional who performs it.

When you use ChatGPT, Gemini or others, your legal files travel to public data centers — subjected to terms of service you don't control and risks beyond privacy.
Public cloud providers are frequent targets of breaches. Your client data stored there is inherently at risk of exposure.
In scenarios of outages or policy changes, access to your cloud documents can be suspended unilaterally.
ABA Model Rule 1.6 requires reasonable efforts to prevent inadvertent disclosure of client information. Sending files to public servers creates an ethical risk.
