AI Tools
Free, private AI utilities — prompt builders and testers, token & cost calculators, model comparisons, output cleaners, RAG and developer helpers, and image-generation prompt builders. Everything runs in your browser; bring your own API key for live model calls.
A complete, privacy-first toolkit for working with AI: build and test prompts, count tokens and estimate API costs across GPT, Claude, Gemini and open models, clean and repair model output, design RAG pipelines, and craft image, video and audio generation prompts. Each tool is single-purpose, instant, and free.
Everything runs client-side in your browser. Tools that call a live model do so directly from your browser with your own API key — your prompts, keys and data are never sent to or stored on our servers. No account, no limits, no lock-in.

Frequently asked questions
Are these AI tools free?
Yes. Every AI tool is free with no account or usage limit. The site is supported by unobtrusive ads. Tools that call a live model use your own API key, billed by your provider — not us.
Do you see my prompts or API key?
No. Tools run entirely in your browser; any prompt, key or data you enter is never transmitted to or stored on a Gera server. Live-model tools call the provider (OpenAI, Anthropic, etc.) directly from your browser.
Which models are supported?
The calculators and comparisons cover GPT-4o/o-series, Claude, Gemini, Llama, Mistral and more; live tools work with any provider whose API key you supply.
Do I need an API key?
Most tools (token counters, cost calculators, prompt builders, comparisons, output cleaners) need no key at all. Only tools that actually run a prompt against a live model require your own key.
