Open-source engine that makes AI drafts read like people

TextHumanize is an open-source text engine that removes the tells of AI writing: filler connectors, flat sentence rhythm, bureaucratic vocabulary. It keeps your meaning, keywords, numbers and code intact, and it explains what it changed. A 38-stage algorithmic pipeline in 25 languages runs fully offline. Use it as a Python/PHP/TypeScript library, through the texthumanize.link web app and API, or in the free browser extension, which can also tell if a whole site was built with AI.

Hey Product Hunt 👋 I built TextHumanize because I kept running into the same problem: AI-generated text *looks fine*, but still feels artificial — repetitive structures, predictable phrasing, and that subtle “AI tone” you can’t unsee. Most solutions rely on more AI. I went in the opposite direction. TextHumanize is a fully algorithmic, open-source engine that works **100% offline** — no APIs, no models, no hidden processing. Just a deterministic pipeline (38 stages) that rewrites text to sound natural while preserving meaning. Key ideas behind it: • Reduce patterns, not just rewrite words • Keep full control (intensity, seed, keyword preservation) • Make it transparent and auditable (metrics + change reports) • Support real workflows (local, CI/CD, private data) It’s already being used in content pipelines, SEO workflows, and internal tools where privacy actually matters. Would love your feedback 🙌 Curious — how do you deal with AI text quality today?

We built an AI-text humanizer that uses no AI. Zero network calls.

Every "humanizer" we tried for our own content was another LLM behind an API: you send your text away and get a new set of AI tells back.

So TextHumanize is plain algorithms. No model, no API key, the library runs fully offline, and the same seed gives the same result every time. It now works in 25 languages, as an open-source library, a web app and a free browser extension.

The hard part turned out not to be rewriting sentences. It was knowing which ones to leave alone.

What's the first thing that gives away AI writing for you?
