Provider, model & API key

Auto-detects language: English gets British refinement, other languages get natural improvement

How it works
Bring your own key

AI writing tool that works with your own API key — no subscription needed

Connect your Google Gemini, OpenAI, Anthropic, Groq, DeepSeek, Mistral, or OpenRouter key. Your key stays in your browser — it never touches our servers. Pay your AI provider directly, often for fractions of a penny per request. No monthly fee, no usage cap, no account required.

Multilingual

Improve writing in any language — auto-detected, edited in place

Paste text in English, French, Spanish, German, Arabic, Japanese, Bengali, Portuguese, Italian, Dutch, Turkish, Korean, Hindi, Russian, Polish, Swedish — or any of the 44 supported languages. TidyText is a multilingual AI writing tool that detects the language automatically and edits in that language — respecting native grammar conventions, not imposing English rules. English text gets British refinement. Everything else gets idiomatic improvement in its own tongue. No account required, no login, no word limits.

Light touch

Edits that improve clarity without erasing your voice

Most AI writing tools rewrite everything into the same bland corporate prose. TidyText is prompted to fix only what needs fixing — awkward phrasing, unclear sentences, grammatical slips — while leaving your rhythm, tone, and word choices intact. The result reads like you, only sharper.

Translation

Translate into natural, idiomatic prose across 44 languages

AI translation with no signup, no account — just paste and go. TidyText translates into language that sounds written by a native speaker — preserving tone, emotional weight, humour, and sentence rhythm. Select your target language, paste your source text, and receive a translation with notes on every key decision made. Improve text online with no subscription and no word limits.

Full transparency

Every prompt is readable in the source — no black box, no hidden rewrites

TidyText does not obscure what it sends to the model. Open the source, find the PROMPTS object, and read the exact instructions your text is edited against. No proprietary magic, no mystery. What you see in the output is the direct result of prompts you can inspect, copy, and modify yourself.
