Your questions say more about you than your posts do.
"What are the early signs of this illness?"
"Can my employer read my messages?"
They show what you fear, what you plan and who you worry about.
Commonplace is an AI research app that cannot send them anywhere. 🧵

We publish how good it is.
On 100 graded questions, Commonplace got 64% of the score of a frontier AI model with web search. That model won almost every single question.
The small model can makes mistakes, and the app has no live news. The first download is about 11 GB.

The wall guards the app. Your keyboard and browser are separate apps, so choose them with care. A download host sees the download, never your questions.
Free and open source, for Android:

What would you ask if nobody could read it?

Commonplace 0.4.0 is out.
An offline research app for Android that answers from a library on your phone and cites its sources.
Now it's way faster, and it reads answers aloud.
No account. No cloud. No network permission at all.
Also new:
- Pack updates in the Library
- 482 pages of folk remedies gone from the Reference shelf
- Ling frees its memory when you leave the app: 4.9 GB to 0.3 GB
- Follow-ups like "shorter" work more often with Ling

The video replays measured numbers. It is not a screen recording.
Known issues are in the changelog. It still gets things wrong, so check the sources it cites.

The next release, Commonplace 0.4.0, gets Gemma's first word 31% sooner on a Pixel 10, fully offline: 1.86 s → 1.28 s (median, 34 questions).
The trick: the CPU and the Tensor NPU no longer take turns. 🧵
Every change in 0.4.0 passes our eval first: the same questions, graded against Claude with web search.
No cloud at any step. Your question never leaves the phone.
