Publish writing you can stand behind

NotepadLLM turns AI-assisted drafts into clear, natural writing that keeps your meaning, facts, voice and ownership intact. A private, no-signup notepad where every edit is one click.

Headline features

Humanizer

Rewrites the patterns AI detectors flag: uniform sentence length, repeated sentence shapes, instruction-tuned phrasing. Your meaning, facts, numbers, names and voice stay exact.

Mochi, in the corner

An assistant who never interrupts. Click her and ask; she answers, edits, emails and talks, and nothing she proposes touches your text until you say so.

Private, no signup

No login to use the editor. Your draft lives in your browser, never on our servers. AI features send your text to the model and return the result; we log tokens and cost, never a word of what you wrote.

What else is in there

AI watermarks scrubbed

Invisible watermark characters and curly quotes that give AI output away are stripped on every paste, and again on copy and export.

Sounds like you

Pro: give it a sample of your own writing and rewrites follow your style. Stored encrypted, switchable per run, deletable whenever.

See what changed

Every rewrite comes with a word-level diff against your original and an explanation of the tells it found. Restore the original in one click.

Nothing gets lost

Undo and redo across every AI edit; your draft and its history are cached locally for a day, so a reload doesn't cost you the work.

Markdown, math and export

The preview renders Markdown and LaTeX math live. Copy as formatted text, or export the page as a PDF.

A real API

The humanizer and editing tools are an HTTP endpoint too, with the same options the editor uses. Documented, versioned, and yours with Pro.
