MustUse.ai is an open-source framework for building ranking sites that Codex agents can fully research and maintain automatically.

Friends often ask me which AI tools they should use for different tasks. I wanted a ranking I could trust and point them to, but many of the lists I found were full of ads, affiliate incentives, or sponsored placements.

I didn’t want to maintain yet another directory by hand, either. So I started wondering whether Codex could research the market, produce the rankings, and keep them up to date. That’s how MustUse.ai started.

The demo currently ranks AI tools, but the same setup can be adapted to other subjects. By changing the included Skills, you can create an agent-run ranking site for games, movies, music, books, software, or almost anything else.

It’s still an experimental project, and I’d love to hear what you think.26:T512,I built my first startup around an optimistic but extremely naive idea: if you get scientists to timestamp their work on a blockchain, and then couple that timestamp with a protective license, you would stop IP theft. This would then allow scientists to collaboratively share data or inventions without fear of being undercut, and thereby usher in a golden age of science.

prove-yourself is a tool that extracts of some of what we built into a simple CLI and web app that lets you:

- Write a statement (a prediction, a claim, a hash of a file) and sign it with a local Ed25519 key - Tie the signing key to your accounts (GitHub, Twitter, HN, etc.) by posting a signed statement - Encrypt the signed statement to a future round of drand, so the decryption key doesn't exist anywhere until the time you picked, using timelock encryption - Anchor the commitment in an Ethereum transaction and on IPFS, so there's a public record it existed by that date - Let anyone decrypt and verify it after the reveal, without you (or any server of mine) being involved

prove-yourself runs as a CLI or in the browser via WASM. Nothing leaves your machine, although if you use the hosted playground, your private attestation will be posted to IPFS and the Ethereum Sepolia testnet through my server.
