Use cases / Law
Contract review.
Every clause cited.
Add a long agreement to your documents and ask about it in plain words. The answer cites the passages it relies on, so each point can be checked against its clause, and it downloads as a Word document. Your browser encrypts the agreement to a hardware enclave before it leaves your device.
An illustration of the workspace. The agreement and the answer are made up, and nothing here is legal advice.
The workflow
See it in the workspace.
Recorded in the workspace; answers scripted for the recording, some clips sped up. The Verified checks ran in the browser against a recorded attestation.
Encrypted before it leaves your device.
In your browser
- Checks the enclave’s hardware attestation before anything is sent
- Encrypts the agreement, your question and each passage to that enclave
- Keeps the passage index, the conversation and the Word file
Undergrove’s relay
- Checks your sign-in and allowance
- Passes the encrypted request on, unable to read it
- Sees its size and time
Inside the enclave
- Turns the PDF into text and indexes it
- Runs the model on your question and the matching passages
- Tinfoil states nothing in it persists between restarts
Before sending, your browser checks the enclave’s hardware attestation against Tinfoil’s open-source release. Answers come back the same way, encrypted until they reach your browser. What verification proves
Features in the workspace today.
Long documents
Documents over 120,000 characters are searched inside an enclave, and each message sends only the passages that match.
Numbered citations
Answers cite passages as [1], [2]; each opens in the document viewer at that place.
Compare
Ask a second model the same question and read the two answers side by side.
Word, PowerPoint and PDF
Download any answer, or the whole conversation, as a file made in your browser.
Projects
Keep a matter’s documents, conversations and standing instructions together, and share it end to end encrypted, with editor and viewer roles.
Receipts
Each answer from an enclave records what your browser verified before sending: the enclave, its code release and the key it encrypted to.
The limits, plainly.
- Answers can be wrong or incomplete, and aren’t legal advice. Check each point against the clause it cites.
- Undergrove holds no compliance certifications, and the workspace, relay and gateway haven’t been independently assessed yet.
- You’re trusting Undergrove to serve the verifying code as published, and Tinfoil’s enclaves to work as described. Whether that suits privileged or confidential material is for you to judge under your own professional rules.
- Vercel, our host, receives ordinary request details such as your IP address.
