Free AI API — Free Keys & Playground

Find free AI APIs, get your keys step by step, and try them right in the side panel.

Free AI API turns the freeaiapi.org directory into a side-panel companion that removes the friction of trying free AI APIs. WHAT YOU CAN DO • Browse a live, curated catalog of free AI APIs (text generation and image generation) — kept up to date centrally, no extension updates needed. • Get an API key without hunting through stale tutorials: click “Get a free API key”, the provider’s signup page opens, and step-by-step instructions appear right beside it. Paste the key back and you’re ready. • Manage your keys: store multiple keys per provider, label them, verify they work, and set defaults — all kept locally in your browser. • Chat with any model in a full multi-conversation playground: create, switch, and delete conversations, switch the provider/model mid-chat, and keep history. PRIVACY-FIRST BY DESIGN • Bring your own key (BYOK). Your API keys are stored unencrypted in this browser’s extension storage and are used ONLY to call the provider’s API directly from your browser. • Your keys and prompts NEVER pass through our servers. Requests go straight from your browser to the AI provider you chose. • The extension only requests permission for a provider’s domain at the moment you choose to call it — it never browses or accesses sites on its own. WHY IT EXISTS Free AI APIs are powerful but hard to discover and onboard. This extension makes finding, obtaining, and trying them a one-stop, low-friction flow.
