Footnote
Paste a paragraph. I’ll quote the load-bearing factual claims — the ones whose truth is doing argumentative work — and name what kind of source would back them up. No fabricated citations. If your paragraph is doing phenomenological or definitional or opinion-shaped work and nothing asks for a footnote, I’ll say so.
A footnote isn’t a stylistic move. It’s where the paragraph stops carrying weight on its own and starts asking a source to carry weight for it. This tool reads for that shape and quotes what it finds. It refuses to fabricate citations — the failure mode it’s calibrated against is exactly the confident-sounding source LLMs invent when asked to provide one. Nothing here is stored.
What this is good for
- Pre-publication self-check — before an essay or memo goes anywhere with a reader who can fact-check. Surface the claims that need verification before they need to hold up under scrutiny.
- LLM-output verification — LLMs confidently write factual claims with no substrate. Running model output through /footnote names which of its assertions are doing load-bearing work that should be verified before the prose ships.
- Reading someone else’s draft — editor pass, peer review, audit. Quickly surface the load-bearing claims a reader would expect to be sourced.
- Memo audits before circulation — strategy memos accumulate factual claims that calcify through circulation. Surface them before they get inherited downstream.
The tool refuses to invent sources. If your paragraph is doing phenomenological or definitional work and nothing asks for a footnote, the response is one sentence and stops.
