Layer 1
Authority above
Retrieved authority, document excerpts, and source material remain visible before the analysis that depends on them.
Supra AI
Secure legal AI without compromise.
See Supra.
AI companies ask you to trust them with your data. With Supra AI, you don’t have to.
Once it’s set up, Supra AI runs locally on your Mac. Your matter files, prompts, and generated work stay on your machine — the only network calls are downloading models, optional CourtListener research, and the update checks you opt into.

Source grounding
See Supra.
In legal writing, supra points back to authority already supplied above. Supra AI applies the same principle to legal AI: the answer should never be severed from the source that supports it.
Layer 2
Answer below
The response is framed as analysis tied to the source packet, not as an unsupported assertion from model memory.
Capabilities
Built for legal work that stays grounded.
Supra AI combines local generation with legal research, document intelligence, and review workflows designed for attorneys.
Featured
Local generation
Supra AI runs models locally on Apple Silicon, so your files and prompts do not need to leave your Mac for generation.

- Source-grounded research
- Research workflows are designed around retrieved source material, not unsupported model memory.
- Citation verification
- Citation-sensitive outputs are built for review, verification, and correction before reliance.
- Document intelligence
- Import matter documents, extract facts, ask questions, and keep answers tied to source material.
- Matter workspace
- Organize research, drafts, documents, outputs, and review artifacts by matter.
Privacy architecture
Legal AI should not require surrendering the file.
Supra AI is designed around a local trust boundary: your app, your models, your matter documents, and your generated work stay on your Mac. CourtListener research is the limited network exception when you choose to use it.
