Everything you need to know about TidyText — how it works, what it costs, who it's for, and how your data is handled.
Getting started
TidyText is a free, browser-based AI writing tool that improves, polishes, and translates your text. You bring your own API key from Google Gemini, OpenAI, Anthropic, or any compatible provider. No account. No subscription. No data stored on our servers.
Everything happens in your browser — your text goes directly to your chosen AI provider, comes back improved, and stays between you and them.
TidyText itself is completely free. You only pay for the AI API calls you make — and that cost goes directly to your provider (Google, OpenAI, Anthropic, etc.), not us.
Most providers offer a free tier that covers typical personal use. For example, Google's Gemini API has a generous free quota. Light users often pay nothing at all.
No. TidyText has no accounts, no sign-up, no email required. Open the app, enter your API key in settings, and you're ready. Your key is saved to your browser's local storage for next time.
TidyText works with:
You choose the provider. TidyText connects directly — it's your key, your model, your cost.
Features & how-tos
Use TidyText's Humanise mode. Paste your AI-generated text, select Humanise, and TidyText rewrites it to sound natural — removing the telltale signs of AI writing: the robotic cadence, over-structured paragraphs, repetitive connectives, and hollow corporate phrasing.
The result reads like a person wrote it. Not a robot trying to sound like a person.
Use Polish mode rather than a full rewrite. Polish corrects errors — spelling, grammar, punctuation — while preserving your sentence structures, vocabulary, and style. It's designed for writers who want clean copy, not homogenised copy.
If you want to adjust the result further, try Improve mode, which rewrites for clarity while keeping your intent intact.
Yes. TidyText includes a dedicated translation mode. Select your target language, paste your text, and TidyText produces a natural, idiomatic translation — not the stilted, word-for-word output of a rule-based engine.
Because it uses the same frontier AI models as your chosen provider, translation quality is typically excellent across major languages.
This is what TidyText's prompts are specifically tuned for. Rather than defaulting to neutral corporate language, TidyText aims to improve clarity and correctness while keeping the human qualities of the original.
For personal or creative writing, Polish mode is your friend. For professional writing where you still want warmth, try Improve — and if the result is too formal, run Humanise over it as a second pass.
Absolutely. Paste your draft email, choose the appropriate mode (Polish for a light clean-up, Improve for clarity, or a custom tone), and TidyText returns a version ready to send.
It's particularly useful for non-native English speakers writing professional emails — improving naturalness and register without losing the original meaning.
Privacy & data
No. Your text goes directly from your browser to your chosen AI provider — it never passes through our servers. Your API key is saved only in your browser's localStorage, entirely on your device.
We have no database of user activity, no logs, and no way to see what you've written. See our full Privacy Policy for details.
No cookies. No analytics. No tracking scripts. No advertising pixels. TidyText uses only localStorage to remember your settings (API key, provider, theme, tone preference) between sessions. Full details are in our Cookie Policy.
TidyText has no access to your text, so we certainly won't train on it. As for your AI provider: API usage (as opposed to consumer product usage) is typically governed by stricter terms that exclude your data from training. Check your chosen provider's API terms — most major providers explicitly exclude API data from model training by default.
TidyText vs alternatives
They serve different needs. TidyText is better if you want:
Grammarly is better if you need deep grammar explanations, browser-wide integration across every text field, or a mobile keyboard. TidyText is a deliberate alternative — not a replacement for everything Grammarly does.
QuillBot is primarily a paraphrasing tool. TidyText focuses on improving the quality and naturalness of your text, not just rephrasing it differently. Key differences:
Most AI writing tools charge a subscription and use their own API access behind the scenes — you pay them, they pay the AI provider, and take a margin. A "bring your own key" (BYOK) tool like TidyText lets you connect directly to the AI provider you already have an account with.
This means lower cost (no middleman markup), your choice of model, and stronger privacy — the tool itself has no visibility into your content.
