Write what you mean.
Write, improve and reuse AI prompts from your browser side panel.
Start with your own prompt or an English or Dutch fill-in template. Add optional context, compare an AI rewrite with your original, then copy it into your AI tool.
Free and Pro
The local prompt library and templates work without an account. For online AI improvements, sign in with an email code. Free includes three AI improvements per calendar month, counted in UTC. Account shows your remaining allowance and reset date.
Prompt Guard Pro includes 100 AI improvements per paid monthly billing period. It renews monthly until you cancel. Unused improvements do not carry over.
Cancel through Account > Manage subscription before your next renewal; access continues until the end of your paid period. How to upgrade and manage your subscription.
Buying Pro is optional. Signing in does not create a paid subscription, and the free plan never converts automatically. Pro is currently offered to customers in the Netherlands. Payment is handled through Stripe. Prompt Guard does not include a subscription to ChatGPT, Claude, Gemini or another AI service.
Your first Pro purchase has a 14-day cooling-off period. If you withdraw in time, we refund the first subscription payment in full, without deducting used improvements. We do not ask you to waive this right. Use Withdraw from purchase, or contact us. Read the Terms before buying.
Keep useful prompts close
Organize your local library with tags, favorites and search. Saved library content and your optional context profile are encrypted in this browser profile. Export a JSON backup before uninstalling, clearing browser data or changing profiles. The export is a readable file, so keep it privately. Version 0.7.0 does not sync or back up your library to the cloud.
Review what you send and receive
Choosing Improve sends the current prompt and any included context to IronStride and OpenAI. Local screening can miss sensitive information. AI rewrites and intent checks can be wrong, so review the result before using it.
