Local-first proof creation
Create evidence. Keep the file.
Choose a file, create its private Verifyum commitment in this browser, and anchor only that commitment on Solana Mainnet for free. The file is not uploaded, and you need no account, wallet, cryptocurrency or payment.
Tips:
Generated locally
Private proof draft
The archive was built in this browser and is the file that gets proven. Copy files out of it freely, but keep the archive itself as it is: unpacked and packed again it is a different file, and the proof will not match.
- File SHA-256
- Verifyum commitment
Free for you: AI SENSE pays the Solana network fee. Keep the downloaded private draft with the original file and save the public proof link after finalization. Fair-use protection includes a 10-per-rolling-hour IP ceiling plus stricter daily, global, balance and service-budget safety caps.
