The launch moved from May 2 to May 16, decided at the April 9 product sync1. The reason was the payments migration: Priya flagged that QA needed two more weeks2. Dan confirmed the new date with the agency by email on April 113. One open loop: the updated press kit he promised is still owed.

One local memory ultramemory.db · on this Mac

Every connector can be paused, scoped, or excluded — per channel, per folder, per person.

Recall

Never answer-only.

Ask in plain language — “when did we decide to push the launch?” — and get a narrated answer where every claim carries a citation. Click one and the original message, file, or screenshot opens beside it, with the full evidence trail in order of events.

When sources disagree, Ultramemory says so: contradictions are detected, tracked, and shown — not papered over.

Privacy

Your memory never leaves your Mac.

Everything is indexed into a single SQLite database in your home folder. No account, no sync, no telemetry — there is no server to send anything to.

You hold the controls: pause capture globally, exclude people and channels, see exactly what is stored and what never is, export or delete it all in one click.

Local AI

No cloud. No subscription. No internet required.

Search works the moment you install — deterministic full-text and vector retrieval, zero AI needed. Add a local model through Ollama and answers become conversational: the model reads only the evidence it cites, on your hardware, even on a plane.

If the model is off or missing, nothing breaks — you simply get ranked results instead of prose.

Optional AI setup
Two commands. Ultramemory detects Ollama automatically and hot-plugs the model.
$ brew install --cask ollama-app
$ ollama pull gemma4:26b
Standard — gemma4:26b · best answers, 32 GB RAM
Light — qwen3:4b · fast and capable, 16 GB RAM
None — extractive search still works everywhere
Free & open source

Costs nothing. Hides nothing.
