    Founder's Note

    Hi, I'm Fekri

    @fekdaoui

    Over the last 15 months, I've built around 10 different AI apps. I noticed I was wasting a lot of time on repetitive tasks like:

    • Setting up tricky APIs
    • Generating vector embeddings
    • Integrating different AI models into a flow
    • Handling user input and output
    • Authentication, paywalls, emails, ...

    So I built something to make it easy.

    Now I can build a new AI app in just a couple of hours, leveraging one of the 10+ different AI demo apps.
