Toolbox

Twenty-five tools for reading a draft, checking its claims and inspecting what it produced.

The first group works on how the writing reads, the second on what it asserts, the third on the artifact itself — a chart at 400%, an image edit against its original, a React component that has to mount — the fourth keeps the evidence on the sentence, the fifth turns the audit into a record, and the sixth works at file scale: a PDF beside the summary written from it, a whole CSV export, and the schema a structured output has to satisfy — and the seventh listens and watches: a voiceover measured for pitch, breath and cadence, a video stepped frame by frame, and the provenance inside a file's own bytes. Everything runs in this browser tab with nothing uploaded and no account required, except the React sandbox, whose code has to be compiled by CodeSandbox.

Factual claim, citation & source verification

Check what the writing actually asserts

Tools that go after substance: summaries traced back to their source, claims carrying an editorial verdict, and the markdown and JSON a model emits validated before it ships.

Inline annotation & sentence diagnostics

Mark the sentence where it stands

Four ways to keep the evidence attached to the text: your own phrase and regex rules in a read-only preview, clichés and citations replaced by badges you can open, paragraphs tinted as you type, and tooltips anchored to the sentence they describe.

These tools narrow the reading. They do not decide.

Highlighting finds shape, and a trace finds claims with no support in the source you pasted. Both are mechanical: they cannot tell you whether a sentence is true, whether a cited study exists, or whether the law says what the draft says it says.

That last step is where the verification console and the expert network come in — structural checks on the same text, then a named reviewer on whatever carries consequences.

Marks first, then the checks that need a verdict.

Fix how the draft reads in the toolbox, then run the console to see what it claims and who has to sign it.
