Prose Coach · PRO — $59
Paste a draft and Prose Coach runs a deterministic, forensic read of the patterns that make writing feel machine-made. It scores the tells, locates every one, and explains it. Your text is scanned entirely in memory — no LLM reads it, and nothing is stored.
Prose Coach diagnoses AI writing the way an experienced editor's gut does, but with math. It measures accumulation — the density of machine defaults per 100 words — rather than hunting single words. The free scan returns full detail on 15 vocabulary categories and 6 structural tells: severity, inline highlights, counts, and a specific fix for each. It also scores burstiness (how much your sentence lengths vary) and flags em-dash density.
Professionals, founders, creators, and anyone whose writing represents them: freelance writers charging premium rates, content marketers whose work gets run through detectors, job seekers writing cover letters, and people who write their own material and need it to sound like them, not like ChatGPT.
15 vocabulary categories and 6 structural tells, fully detailed with fixes and inline annotations. Up to 20 scans a day. No account, no email.
The complete 13-part methodology, packaged as a skill file for the AI tools you already use (Claude, ChatGPT, Cursor). Load it once and it applies the methodology in context — rewriting against the patterns rather than handing you a checklist:

The pattern catalog was built from enterprise corpus research across 3.3 million documents and cross-referenced against LLM training signatures. Thresholds are empirical. The scanner is deterministic: it doesn't guess, it doesn't phone an LLM, and it gives the same answer every time. It flags accumulation, not intent — PRO includes voice-preservation valves so the methodology edits autopilot text without touching your intentional moves.
An AI writing filter. Paste a draft and it runs a deterministic, rule-based scan that finds the vocabulary and structural patterns that make prose read as machine-generated, scores their density, and explains each one. The free scan runs in your browser; PRO is a $59 skill file that applies the full editing methodology inside ChatGPT, Claude, or Cursor.
AI writing gives itself away through accumulation, not single words: default vocabulary (delve, tapestry, testament), structural tells (colon chains, restatement loops, symmetrical lists), flat sentence rhythm (low burstiness), and over-even paragraph energy. Prose Coach scores this pattern density and marks every instance in your draft.
The free scan diagnoses — it locates and explains the tells. PRO is the cure: a skill file you load once into your AI tool that rewrites against the patterns in context, using a three-pass revision protocol and voice-preservation valves so the edits still sound like you.
No. The scan is deterministic and rule-based — no LLM ever reads your text. Drafts are scanned in memory, never stored, and never used to train anything.
Detectors give you a probability score and stop there. Prose Coach targets the underlying structural markers those detectors are built to flag — it shows you which patterns fired, why each is a tell, and how to fix them, and PRO makes the fixes automatically inside your writing tool.
