How it works
How ProseMap works
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. ProseMap reads it one sentence at a time, scores each sentence and each join between two sentences, and draws the result as a map. You read the map, decide what matters, and revise: by hand, or by asking for suggested wording for one passage, which you keep or drop. Then you analyse the new version and compare the two. It is for people who write often and revise their own work: essays, articles, newsletters, chapters, posts and reports.
What you give it
- A draft, pasted, or uploaded as a
.txt,.mdor.docxfile. Headings, lists and emphasis are kept. A.docxis converted in your browser; the file itself never leaves your machine. - The price, before anything runs. A 1,000-word draft is about $0.59. A failed analysis costs nothing.
- Before the analysis, one spelling and grammar pass. You see the corrections and approve them, or keep your original. ProseMap does not check as you type.
What it reads
| Signal | What it is |
|---|---|
| Sentence strength | Every sentence gets a score from 0 to 100 for how well it does its job where it stands, judged on clarity, precision, economy, control, function. A correct sentence that adds nothing scores low. A deliberate fragment can score high. |
| Handoffs | Every join between two sentences gets a score from 0 to 100 and a relation: advance, deepen, contrast, disrupt (controlled), restate, drift, pivot, payoff, sibling. This is how ProseMap sees prose that reads smoothly and goes nowhere. |
| Arc | One judgment of the whole piece: whether the sections progress, which threads are left open, where a sustained weak run drags it down. |
| Bands | Numbers are secondary. Each sentence and handoff is shown in one of six bands, exceptional, strong, acceptable, mixed signals, weak, failing, and the map leads with colour, pattern and underline, never colour alone. |
| Hotspots | The handful of places where one fix buys the most, ranked. Weak runs first, then a weak join between two strong sentences. |
The scores come from an AI model reading your draft with a fixed rubric; a second model re-checks a selected subset and disagreements are marked as contested. Every score carries a confidence. What every number means, and the glossary of relations, roles and flags.
What the numbers mean
Most good prose scores between 70 and 85. An all-green map is not the goal; some of the strongest sentences in a piece are the abrupt ones, and the evaluator marks those as controlled rather than penalising them. Treat the map as a careful reader's opinion: useful for finding where to look, not a verdict. ProseMap's scores and explanations are produced by AI models. They can be wrong, incomplete or misleading, and they are one reader's judgment rather than an objective measure of writing quality. Check anything that matters independently.
What you do with it
- Read the map. Tap any sentence for its score, its band and both handoffs. Ask for a plain-English explanation of any judgment.
- Leave notes. Typed or dictated: "make this land harder", "keep this blunt". Every later suggestion follows them.
- Disagree. Move a sentence or handoff to the band you think is right, with a note. Your view is stored beside the evaluator's, never over it, and the document can be re-scored under your view.
- Suggest. Ask for new wording for one passage. It is previewed with the original beside it, and you keep it, edit it, or drop it. Nothing else on the page changes.
- Improve draft. One pass over the whole text that follows your notes, proposes fixes for the weak spots, and scores the new version next to the old. A rewrite can trade one strength for another, so you choose which version to keep.
- Versions. Paste a new version and it is linked to the last one, with score changes and both maps side by side. Your Library keeps every version.
- Export. Copy or download an editing brief, which is your draft with your notes and the weak spots marked, or the analysis as JSON.
- Elsewhere. Run the same analyses from Claude, ChatGPT or Claude Code through ProseMap's connector, or from the WordPress editor.
What it never does
- It never writes a piece from a prompt. There is no blank page that fills itself.
- It never changes your text without your tap. Suggested wording is a proposal until you keep it.
- It never claims its scores are objective. They are one reader's judgment, with confidence shown.
- It never checks facts, and it is not a grammar checker that runs as you type.
- It never uses your writing to train models, and never sells it. What happens to your text.
- It never charges for a run that fails, and never charges more than the maximum shown before you press the button.
Who it is for
It is for people who write often and revise their own work: essays, articles, newsletters, chapters, posts and reports. It works on a phone as well as a desk. It does not write for you, and it is not a grammar checker. If you want a tool that writes for you, this is not it; if you want to see what your draft is doing and fix it in your own words, it is.
