Mono
Mono is an AI agent platform that lets users create custom AI assistants with unique personalities and instructions, then chat with them persistently — similar to building your own GPT.
What users can do
- Sign up with email/password, GitHub, or Google via Better Auth
- Create and manage AI agents with custom names and instructions
- Start and manage persistent chats with any agent
- AI-powered replies using Gemini (gemini-2.5-flash) with conversation history
- Persistent chat message history stored per session
- Search and paginate agents and chats
- Meetings module with status lifecycle (upcoming, active, completed, processing, cancelled)
- Video calling integration via Stream Video SDK
Why I built this
I built Mono to explore how custom AI agents with distinct instructions can power different workflows in a single unified chat interface. The goal was to make it easy to spin up purpose-built assistants without any configuration overhead.
