Free AI Tools — Bring Your Own API Key
AI writing and coding helpers that run on your own API key. Summarize long text, rewrite and change tone, and get plain-English explanations of code — connecting directly from your browser to OpenAI, Groq or any OpenAI-compatible provider.
Bring-your-own-key means there's no subscription, no credit system and no markup: you pay your provider directly at cost, and many offer a free tier. Your key is stored only in your browser and requests go straight to the provider, so neither your key nor your text ever passes through our servers.
What's included
- AI Text Summarizer — condense articles, reports and transcripts into a TL;DR, paragraph or bullets.
- AI Paraphraser / Rewriter — reword text and shift tone between professional, casual, formal or concise.
- AI Code Explainer — step-by-step explanations of a snippet, plus likely bugs to watch for.
Why bring your own key
Most free AI tools either cap usage hard, insert their own margin, or route your text through their infrastructure so they can meter it. Connecting your own key removes all three: you get the model you choose at the price your provider charges, with no ceiling beyond your own account, and your content goes directly to that provider. Providers such as Groq offer a free tier, so this can cost nothing at all.
Frequently asked questions
What does bring-your-own-key mean?
You supply an API key from a provider like OpenAI or Groq. Requests go directly from your browser to that provider, so you control the cost and we never see your data or your key.
Where is my API key stored?
Only in your browser's local storage. It is never uploaded to or stored on our servers.
Can I use these for free?
Yes. Several providers, Groq among them, offer a free API tier that's enough for regular use of these tools.
Which providers work?
Any OpenAI-compatible endpoint, including OpenAI, Groq and OpenRouter, plus custom endpoints you configure yourself.
