Lethe
Lethe is user-owned memory for AI agents. What an agent learns about you is encrypted in your browser, stored as blobs on Walrus, and referenced by a Sui object you own. Any app you authorize can use it; revoke the grant and it stops — live, enforced on-chain.
Live on Sui testnet today at lethe-gold.vercel.app. Built for Sui Overflow 2026, Walrus track.
Quickstart — the whole loop in two minutes
- 01Sign in with Google — zkLogin creates your address, an Enoki-sponsored transaction mints your memory vault. No wallet, no gas, no seed phrase.
- 02In /chat, press Analyze my on-chain activity — Lethe reads your real Sui history and suggests trait cards. Nothing saves until you press Save.
- 03Tell it something durable (“I never trade with leverage”) — watch the fact settle into the memory rail with live Walrus and Suiscan links.
- 04Open /memory— every entry, the apps you’ve authorized, per-entry forget, and export. This is the ownership surface.
- 05Grant Pulse (a second, visually distinct app) — it greets you already knowing your style, from the same vault.
- 06Revoke Pulse on /memory, reload /pulse — it knows nothing. That is the product.
What makes it different
- Memory is an owned Sui object, not a row in someone’s database.
- Seal threshold encryption end-to-end: Lethe’s servers cannot read your memories (see Security).
- Model-independent: switch the answering model mid-chat; memory follows you.
- Export and leave any day — we lock you in with value, not custody.
