TidyText connects to Google's AI using your own free API key. No subscription, no account, no data stored. This guide walks you through getting a free key and pasting it in — takes about five minutes, even if you've never done anything like this before.

What's an API key? It's a short password that connects TidyText to Google's AI. Google gives you one for free when you sign up for AI Studio — it's like a library card for their AI service.

TidyText stores your key only in your browser. It never passes through our servers, and we never see it. You can delete it from your browser any time.

How to get started

Go to Google AI Studio

Open aistudio.google.com in a new tab. Sign in with any Google account — your Gmail works perfectly.

💡 No Google account? Create one free at accounts.google.com — takes about two minutes and requires no payment details.

Create your API key

In the left sidebar, click Get API key. On the next screen, click Create API key. A long string of characters will appear — this is your key.

🔒 Copy the key as soon as it appears — paste it temporarily into a notes app. You can always create a new one if needed, but it's easier to copy it now.

Open TidyText settings

Come back to this tab and go to tidytextai.com. Click the settings icon ⚙ in the top-right corner. The settings panel will slide open on the right.

Choose Google Gemini and paste your key

Under AI Provider, select Google Gemini. Paste your API key into the field below. Leave the model set to Gemini 2.5 Flash — it's the best choice for most people and uses the least of your free allowance.

Click Save. Your key is stored in your browser only — nothing is sent to us.

✅ Your key saves automatically. You won't need to paste it again unless you clear your browser data or switch devices.

You're ready — write something

Close the settings panel. Paste any text into the main box — an email, a paragraph, a social post, anything. Hit Improve or Translate and your result will appear in seconds.

🆓 Google's free tier covers around 1,500 requests per day on Gemini 2.5 Flash. For personal writing use, most people never come close to that limit.
