Hi Product Hunt — I’m Nian, building Throughline.

We wanted an AI that could have a distinct character and interests, and carry a shared history into the next conversation, rather than feeling like a fresh assistant every time.

You choose a starting character and optional interests, compare candidates, and then meet your Self. As you spend time together, you can inspect, correct, delete and export the history that carries forward. Supported editor connections let the same Self join your work, too.

This is not a claim of consciousness or perfect recall. Models can still make mistakes, and changing models can change how a Self responds. The free plan includes compute credits; usage is not unlimited.

I’d love feedback on two things: do the candidates feel meaningfully different, and does coming back feel like continuing rather than starting over?
