For whom
Built for the professions of law and accounting.
Accountants & audit
Ledgers, filings and audit files cleansed of every personal identifier before a model ever sees them.
Any confidential file
Notarial, HR, M&A, healthcare, pharma, defense, internal investigations: anywhere AI is useful but stops at the boundary of confidential data.
Why Hexagone AI
Three guarantees that change how AI is used in firms.
On your machine. Period.
Detection, anonymization and synthesis run on your Mac or PC. No cloud, no third party, no round trip. Compatible with professional secrecy and GDPR.
Compatible with the AI you already use.
Claude, ChatGPT, Cursor, Copilot, your internal copilot. Hexagone AI is the confidentiality layer, not yet another assistant.
Always up to date, without thinking.
Point at a folder (clients, audits, working files). Hexagone AI keeps a protected copy that follows every change.
The product
Three pieces. One confidentiality guarantee.

How it works
From your folder to your agent, in three steps.
Step 01 Pick a folder
Select a local directory or a connected cloud workspace. Hexagone AI reads it in place. Originals never move.
Step 02 Hexagone AI anonymizes
Local models detect identifiers (names, addresses, dates, amounts) and replace them with neutral but realistic markers.
Step 03 Plug in your AI
Open the anonymized copy in Claude, ChatGPT, Cursor or your internal copilot. The mapping stays with you.
Security & compliance
Built for professions where error is not an option.
100% on your computer
Detection, anonymization, mapping: everything runs locally. No original file is ever sent to a server.
No third parties, no lock-in
Hexagone AI sends nothing to subprocessors. You're free to uninstall at any time.
Complete audit trail
Every detection, every substitution is logged locally. Exportable for internal or regulatory review.
On-premise or air-gapped
The Enterprise plan deploys inside your own infrastructure, including fully air-gapped, with SSO and a CLI. Our detection logic is documented and the technical reports go to your security team.
Platforms
macOS Apple Silicon and Windows 10/11 64-bit, 8 GB of memory minimum. Hosted web app and REST API on EU infrastructure.
File formats
PDF, DOCX, XLSX, PPTX, TXT, rebuilt with their original layout. Local OCR for scanned and image-only PDFs.

Client stories

« This partnership lets us do what many still consider incompatible: use the best AI models on the market while guaranteeing absolute confidentiality. »
« Thank you to your team for your help, for this excellent product, and for listening to what we needed! »
« I pseudonymise every one of my documents up front with Hexagone AI. Claude NEVER touches my original files. That is the golden rule. »
« The work of a lawyer or accountant is protected by professional secrecy. The tools they use to produce it shouldn't change that. »
