Squiggle - Privacy focused grammar corrector 제작자: ywnz

Made and maintained by a single developer: a privacy-focused writing corrector that works in every language — free.

Catches grammar and spelling mistakes with squiggly underlines; fix one, fix all, or preview before anything changes
Improve style, rewrite with your own prompt, translate, generate — in any text field, on any site
Auto-detects whatever language you write in; Czech is proofread by hand
FREE, CHEAP PREMIUM

Sign up with your email — no card — for a generous daily quota. Cheap premium tiers (bigger quotas) are planned. No ads, no selling data
Or use your own OpenAI-compatible key: nothing passes through us

Your text is processed only to return your result and is never logged; AI calls go only to zero-data-retention providers. We store an email, a password hash, and usage counters — nothing else. Full policy: squiggle.ywnz.dev/privacy
