GistForge

A short summary feels like the idea — but does it keep it?

When you cut a passage down to a summary, it is easy to keep the shape of the idea and quietly drop the parts that carry its meaning. GistForge makes the drop visible: you read a passage and write a summary, then Tote — a friendly novice who has read only your card — holds exactly the ideas your words carried. What Tote cannot hold is what your summary left behind, and the five losses show you precisely what dropped.

How it works

  1. Read a passage. A short, true idea from science, history, or learning.
  2. Write a summary. In your own words — the whole point is to compress it.
  3. Tote holds your card. Tote reads only your summary and holds only the ideas it carried.
  4. See the losses. The five losses reveal what dropped — then rescue one and check again.

Everything stays on this device. No account, no feed, no timer, no score to chase — Tote never writes for you.
