A summary can feel right and still overstate — or invent.

A short summary is a compression, and compression is where a claim quietly changes. The cleanest failure is the stretch: every word traces back to the source, but the summary drops the caveat — the “only when”, the “not always” — and states it as absolute. The louder failure is the invention: a number, a name, or a fact the source never carried. FidelityForge trains the reader’s core defence — hold the summary against the source — by asking you to audit three of them at once: one faithful, one stretched, one invented. Sort them, then see exactly how each one gives itself away.

How it works

  1. Read the source. A short, real idea from economics, science, history, or medicine — paraphrased, never a fabricated quote.
  2. Audit three summaries. Judge each: faithful, stretched, or invented. Exactly one of each.
  3. See the tell. The reveal shows how each overclaim and fabrication gives itself away when you hold it against the source.
  4. Move on. A calm, on-device note quietly tracks which verdict you miss most — no score, no streak.

Everything stays on this device — no account, no feed, no real brands. FidelityForge judges a summary against its source; it never writes one for you.

The fidelity crew

  • Tenet — the editor who holds the source as the ground truth and asks of every summary, “does this still hold true to it?”
  • Verith — reads a summary and confirms every claim traces back and a caveat is kept, and that it adds nothing. That is faithful.
  • Caven — guards the caveat, the “only when / not always”. When a summary quietly drops it and states the claim as absolute, that is a stretch.
  • Fabb — checks each claim against the source. A claim that simply is not there — a number, a name, a guarantee — is an invention.
