Thanks for checking out Perpendo! Happy to answer any questions.
Why I built this: I use AI constantly for my doctoral research, coaching practice, and business planning. But I was frustrated juggling Claude, ChatGPT, and Gemini in separate tabs -- paying $20/month to each, losing conversations, and never being able to compare their answers. I wanted one place to think with all of them. Nothing existed that did it well enough, so I built it.
A few things I'm especially proud of:
Conversation branching: Fork any conversation at any point, explore a different path, and navigate between branches with a visual tree. This changes how you think with AI.
Continuous model comparison: Send the same prompt to multiple models, then keep the conversation going. Watch how Claude and GPT diverge over multiple turns on the same topic. Nobody else does multi-turn comparison.
Built by a non-engineer: I'm a rehabilitation counselor. The entire platform was built using Claude Code. If that doesn't convince you AI is changing who can build software, I don't know what will.
Self-hosted option: Download, unzip, double-click. No Docker, no terminal. Connect Ollama for fully private, zero-cost local AI.
Use code PRODUCTHUNT for 50% off (forever!) during our public beta (expires April 18).
Happy to answer anything about the product or what led me to build it.
Curious -- for those of you using multiple AI models, what's your current workflow? Do you keep separate tabs open, or have you found a better way?
