Give your AI agent an expressive face. AllPersonas is a web SDK with 6 characters, 24 expressions, and speech support. Use your own model, voice, and framework. Explore the playground or build with the starter app.

What became possible in your product with Astra that was not practical before?

I used GPT-6 Astra in Codex to build AllPersonas: a face for your AI agent. The biggest unlock was making a complete, reusable SDK practical to build, with six characters, 24 expressions, speech support, and integration across web frameworks. These pieces need to work together: the character's expression, speaking state, and mouth movement all respond to the conversation. Astra helped me turn that idea into working code and iterate on the system. The result is a toolkit developers can connect to their own agents, models, and voices, with a playground and starter app to help them get started.

Hey Product Hunt 👋 Meet AllPersonas: a web SDK for giving your AI agent an expressive face and a voice. Your application supplies the conversation. AllPersonas brings it to life with six characters, 24 expressions, blinking, gaze, and speech-driven mouth movement. You can use it with JavaScript, React, Vue, Svelte, or Angular, and connect your own model and voice setup. The playground supports OpenAI, Anthropic, and Vercel AI Gateway, with browser speech or ElevenLabs. Start by exploring the faces without an API key, or run the starter app to build a complete expressive agent. This is an alpha release, and I’d love feedback from developers building assistants, tutors, and other conversational experiences. What would you build with AllPersonas and which character, expression, or integration would you want next?
