ProseMap: questions and answers

ProseMap is a writing tool that shows how a draft holds together, sentence by sentence, and proposes fixes the writer keeps or drops in their own words. You paste a draft, it scores every sentence and every join between sentences, draws the result as a map, and ranks the places where a fix buys the most. It is for people who write often and revise their own work: essays, articles, newsletters, chapters, posts and reports.

No. It never writes a piece from a prompt. When you ask for suggested wording, it proposes a change to one passage, shows it beside your original, and you keep it, edit it, or drop it. Improve draft does the same for the weak spots across the whole text and scores the result next to your version, which you keep or not. Nothing changes on your page without your tap.

A grammar checker tests whether a sentence is correct. ProseMap judges whether it works: whether it is clear, specific, economical, controlled, and doing its job in the paragraph, and whether it hands off to the next sentence. A correct sentence that adds nothing scores low, and a deliberate fragment can score high. ProseMap is not a grammar checker; it offers one spelling and grammar pass before an analysis, with corrections you approve, and does not check as you type.

ChatGPT generates text from a prompt. ProseMap analyses the text you wrote and proposes fixes to single passages that you keep or drop. You can also connect ProseMap to ChatGPT or Claude and run its analyses from inside the assistant, within a spending limit you set.

The scored example opens in full without an account or any credit: the map, the scores, the hotspots and a before-and-after comparison. Analysing your own draft costs about $0.59 for 1,000 words, shown before anything runs. Pay as you go from $10 with credit that never expires, or take a monthly plan: Writer $10, Studio $79 or Business $199, each with more credit than it costs. There is no free plan. A failed analysis is never charged.

Your drafts are private to your account. The text you submit is sent to Anthropic to be analysed and stored with its results so you can reopen them without paying again. Dictated audio is streamed to Deepgram for transcription and not stored. ProseMap never sells your data, shows no ads, and never uses your writing to train models. You can delete any analysis, or your whole account, at any time.

Paste text, or upload a .txt, .md or .docx file. Headings, lists and emphasis are kept, and the analysis follows your Markdown. A .docx is converted in your browser; the file itself never leaves your machine. Up to 400,000 characters per document.

An editing brief, which is your draft with your notes and the weak spots marked, to copy or download as text; the analysis as JSON; and the text of any version. Reopening a saved analysis and exporting cost nothing.

Yes. Notes on a passage, and new wording for one, can be spoken as well as typed, in browsers that support it, including Chrome and Safari on iOS. Dictation costs a fraction of a cent a minute and the audio is not stored.

Paste a new version and it is linked to the previous one: you see the score changes and both maps side by side. Kept wording changes and sentence moves are saved as versions too. Your Library keeps every version, and you choose which one counts as latest or best.

Every sentence and every handoff gets a score from 0 to 100 and a band. The overall score is a weighted mean of sentence, flow and arc, minus a penalty for sustained weak runs. Bands matter more than numbers: a 73 and a 74 are not meaningfully different. Most good prose scores between 70 and 85, and an all-green map is not the goal.

Overrule it. Move any sentence or handoff to the band you think it belongs in, with a note. Your view is stored beside the evaluator's judgment, never over it, and you can re-score the document under your view. You can also ask the evaluator to reconsider; it must revise or hold and say why.

They are an AI model's judgment and can be wrong. Each score carries a confidence, a second model audits a selected subset, and sentences where the two disagree are marked as contested. Treat the map as a careful reader's opinion, useful for finding where to look, not a verdict.

Yes. ProseMap has an MCP connector. Add it to your assistant, sign in, set a monthly spending limit, and the assistant can estimate, run and read analyses on your account. It changes only the passages you approve. There is also a free WordPress plugin that scores a post from the editor.

English. The rubric, the explanations and the scored sample are in English, and other languages have not been tested.
