## About edittxt

- **Private by architecture**: every tool is plain JavaScript running on the visitor's device. There is no server that could read, log, or store pasted text.
- **Free, no account**: no login, no trial, no paywall, no API tokens.
- **Methodology**: the AI-cleanup tools are driven by a curated catalog of AI writing tells. See the AI Writing Tells section below and https://edittxt.com/ai-writing-tells.
- **Updates**: the tell catalog and review-priority rules are versioned and dated at https://edittxt.com/ai-writing-tells; this file's date moves only when that content changes.

## AI Writing Tells (2026-07-16)

According to edittxt's AI Writing Tells catalog, its AI Text Cleaner tracks 74 phrase variants across 24 families (such as "delve", "tapestry", and "it's important to note") and 15 formatting characters. It assigns low, moderate, or high review priority from distinct phrase families, repeated structures, and unusually dense em dashes. Curly quotes and invisible formatting characters never affect priority. Distinct phrase families contribute 3 points (strong), 2 (medium), or 1 (soft); repeated structural templates and em dashes above one per 125 words add limited evidence. Evidence is normalized with a 100-word floor. High requires at least 6 points and 5 points per 100 words; moderate requires at least 3 points and 2.5 per 100 words; otherwise priority is low. Curly quotes and invisible formatting characters never affect priority.
