A memory system for your personal assistant

Remember what matters.
Know where it came from.

Conversations move on. The useful details shouldn’t disappear with them. Memento gives your AI assistant a lasting memory, with the original evidence always attached.

Self-hosted. Evidence-backed. Your instance, your data.

Less re-explaining. More continuity.

A memory should be useful.
And accountable.

Memento keeps raw history and derived memories distinct. You can retrieve the useful detail without losing the conversation that supports it.

  1. Keep the original

    Native integrations capture conversation records. Imported histories use stable identities, so repeating an import doesn’t create another copy of the same event.

  2. Find the relevant detail

    Recall combines semantic search with exact source evidence. Personal and professional scopes help keep context focused. Unconfirmed candidates remain distinguishable from confirmed memories.

  3. See what changed

    Corrections and refinements preserve history, reasons and supporting quotes. Follow-ups are reactive markers—not an autonomous agent making promises on your behalf.

A public website. Not a public memory.

Private by architecture.
Not by wishful thinking.

Your memory service runs on your infrastructure. This website is an introduction: it does not expose a memory database, a search endpoint or an account portal.

Google Drive is an optional archive and recovery destination. Memento requests drive.file access for its app-accessible files, not blanket access to your Drive. Backups are requested by the owner, not silently scheduled.

Keep the context. Keep the evidence.
