My AI

My AI lets you build a custom AI persona at free.ai/@yourhandle. Pick a name, write a system prompt, upload knowledge sources for retrieval-augmented chat, and choose voice + model preferences. Your @handle is publicly browsable so others can discover and chat with your AI; you also get a private side that only you can use.

Click "Create" on this page or go to /my-ai/create/. Pick an @handle (e.g., free.ai/@you), name your AI, write a system prompt that shapes its personality and expertise, optionally add knowledge sources (paste text, fetch a URL, or add Q&A pairs), and pick a voice + default model. Anyone visiting your @handle URL can chat with the public version.

Active paid subscribers can create @handles for free. Non-subscribers can also create one — upkeep is 50,000 tokens/month from purchased credits. The free daily token pool and education credits don't qualify for handle creation, since @handles are persistent identities tied to your billing relationship.

Public mode is what every visitor to free.ai/@you sees — your AI's public personality, public knowledge base, public greeting. Private mode (only you can access at /@you/chat/?private=1) uses separate prompt + knowledge fields you fill in. Use it as a personal assistant with private docs, while keeping the public side polished for visitors.

Add docs via paste-text, URL-fetch, or Q&A pairs. Free.ai chunks each source (~1,500 chars with 200 overlap), embeds the chunks, and on every chat retrieves the most relevant ones to inject as context. So your AI can answer with your data — product docs, your bio, your company FAQ, anything you upload.

Yes. Pick a voice from the catalog (174 voices, 37 languages) and visitors can hold a real-time voice conversation with your AI on /@you/chat/ — mic in, AI replies in your chosen voice. Powered by Whisper for speech-to-text + Kokoro for text-to-speech, both self-hosted and free in the daily pool.

You pick a default. Free options: Qwen 3 30B, DeepSeek V3, Mistral 7B (all self-hosted, free). Premium options: GPT-5, Claude Sonnet 4.6, Gemini 2.5 Pro, etc. Visitors can switch models mid-chat. Your "default" just sets the first response. Premium model usage deducts from the visitor's tokens, not yours.

Share your URL: free.ai/@yourhandle. The page is publicly indexable, has Open Graph + Twitter Card metadata, and renders well as a link preview on social media. Add it to your bio, business card, email signature — every visit drives chats and rating, which boost discovery on this browse page.

The visitor pays from their own daily token pool (or purchased credits if they pick a premium model). You don't bear the cost of their chats — only the upkeep of your handle (free for subscribers, 50K/month otherwise). This makes My AI handles sustainable for hobbyists, creators, and businesses alike.

You can edit your AI's name, prompt, knowledge, and avatar anytime at /my-ai/edit/. The @handle slug (the part after @) is harder to change — it leaves your old links broken — but you can have multiple @handles per account if you outgrow your first.

Yes. Toggle "Published" off in /my-ai/edit/ to hide your AI from this browse page (existing chat URLs stop working). Or delete the AI entirely — knowledge sources, conversations, and ratings get removed. The @handle slug is held for 7 days after deletion in case you change your mind.

Yes. POST to /v1/agents/<slug>/chat/ with your messages — streaming supported. Use GET /v1/agents/ to list all published handles. Combine with /v1/tts/ + /v1/stt/ to build voice agents with your AI's personality. See /api/ for OpenAI-compatible curl + Python + Node snippets.
