🚀 Day 2: Custom Internal API/SDK Knowledge Base

Introducing Day 2 of sampleapp.ai launch week - "Custom Internal API/SDK Knowledge Base"

Most AI tools today hallucinate because they simply don't have the latest, complete picture of your API/SDK. Today, we're closing that gap. Power Your Playground with Your Own API /SDK Knowledge Base.

Here's how it works:

  • 📚 Ingest any source — Existing docs (Mintlify/Fern/Gitbook etc.), OpenAPI specs, Markdown docs, your own sample apps, and more.
  • 🚀 Train on your API/SDK's true "single source of truth," so every prompt, every code snippet, and every example is 100% accurate.
  • 🤝 Seamless integration — plug it into your existing Sampleapp playground and watch your own knowledge base power the AI.

Why it matters:

  • 🔍 Better development experience — no more endless error loops.
  • ⚡ Lightning-fast answers — developers get context-aware snippets and full working apps in seconds.
  • 🔄 Always up-to-date — hook into your CI/CD or docs pipeline so your playground evolves with every commit. (Coming soon)

With your own custom knowledge base, you can launch multiple Prompt-to-App playgrounds, each using a different API version or SDK.
