What Pulzer does

Encrypted at rest

Your chats are stored encrypted with keys derived from your password or recovery phrase. Plaintext never touches disk — a database leak alone can't be read without your key.

How it works

Three steps, all yours

  1. 01

    Create your account

    Pick a password and get a 12-word recovery phrase. That’s your key — we never see it.

  2. 02

    Chat with memory

    Ask anything, fast or in deep-thinking mode. Pulzer remembers what you want it to.

  3. 03

    Encrypted at rest

    Everything is stored encrypted, locked by your key. Plaintext is never written to disk.

FAQ

Questions, answered

Yes. Pulzer is free to use, with fair-use rate limits so everyone gets a turn. No paywalls.

No — and there never will be. Pulzer is free, funded by contextual ads.
