Free AI tools FAQ

Are these AI tools really free?

Yes, with no sign-up. They run on your own OpenRouter account — free models cost nothing, and paid models are billed per use by OpenRouter, usually a fraction of a cent.

What is OpenRouter?

A service that gives one key access to hundreds of AI models from OpenAI, Anthropic, Google, Meta and others. You connect it once and every tool here uses it.

Can I use GPT, Claude or Gemini models?

Yes. Pick any text model OpenRouter offers in the model list — free models are marked.

Is my data private?

There is no AI WebTools server. Your key and history stay in your browser, and your text goes straight from your browser to OpenRouter.

Do I need to create an account?

Not with us. You only need an OpenRouter account, which you can create or connect in one click from the Connect AI button.

Are there usage limits?

None from us. Free models have rate limits set by their providers; paid models only cost what you use.

Which AI model should I choose?

A small, fast model is fine for captions, hashtags and short copy. Pick a larger model for long articles and documents.

Do the tools work on my phone?

Yes. Every tool works in a mobile browser, and your history stays on the device you used.
