Unibase Memory
Chrome extension for cross-AI memory you encrypt, own, and verify.
Unify conversations and knowledge across ChatGPT, Claude, Gemini, and more — backed by the Membase network, not a vendor database. Unlike typical browser memory extensions, your data stays encrypted on-device and syncs as ciphertext to Membase.
Sign in with Google, X, or wallet via Unibase Pay (Privy). Storage and identity — one Unibase stack.
Encrypt
AES-256 on your device. Wallet-derived keys — not passwords we store.
Own
A cross-AI archive you keep. Not a feature locked to one chatbot vendor.
Verify
Backups anchored on Ethereum. Prove integrity without trusting our servers.
Why not typical memory extensions?
Many plugins offer local or cloud memory management. They are convenient — but your data often stays on a vendor stack you cannot verify or take with you if the service changes.

Vendor memory is a product feature. Unibase Memory is an encrypted archive — portable across every assistant, on infrastructure no single company controls.
How it works
Capture in the browser → encrypt locally → sync to Membase.
Capture
Chats and saved pages in Chrome — no copy-paste.
Encrypt
Wallet-derived key, local encryption before upload.
Sync
Back up to Membase; restore on any device when you sign in.
What you get
The same Membase pipeline developers use via SDK, MCP, and skill — packaged as Unibase Memory for Chrome.
Cross-AI archive
ChatGPT, Claude, Gemini — one searchable history that follows you.
Personal library
Save pages and posts for RAG across assistants, synced via Membase.
Decentralized sync
Ciphertext on the Membase network — not a vendor database.
Unibase Pay
Sign in with Google or X via Privy. Embedded wallet for keys and storage.
Privacy & wallet
Sign in with Google or X via Privy (Unibase Pay). Keys and cleartext stay on your device; we only ever hold ciphertext on Membase. Your decryption key never leaves your control.
Restore on any device: sign back in, re-derive your key, and pull your archive locally.
