AI Analysis

●●SolidBig BrainZero to OneShip It

Self-generating apps from usage patterns and unified intent routing, but needs proof it outperforms Claude Projects.

Strengths
  • •Intent coordinator abstraction lets you swap input modalities (gamepad, voice, gestures, tracking) without rewriting skill logic—genuinely clean architecture.
  • •Recursive learning + conviction scoring automatically surfaces obscure knowledge without generic top-10 lists; privacy-first event tracking only.
  • •60+ namespace SDK with built-in apps (calendar, timer) that Prvctice generates itself—real meta-bootstrapping, not theoretical.
Weaknesses
  • •No clear evidence that curated knowledge graphs prevent hallucination better than baseline RAG; claims need side-by-side benchmarks.
  • •Requires API keys upfront; offline-first storage is local-only (IndexedDB), making multi-device sync a future problem.
Target Audience

Creative directors, researchers, knowledge workers building custom workflows; developers interested in agent architecture.

Post Description

Started as a personal research tool — I was buried in notes and needed something that could connect sources without hallucinating. Instead of feeding it content, I built a system-prompt structure using curated knowledge graphs that shape the model's prior. It surfaces things I'd never heard of without just pulling from generic top-10 lists.

Over 14 months it grew into something I'd call a DIY OS. Key parts:

- A recursive learning system that tracks tool usage and re-ranks tools based on your habits - An intent coordinator that abstracts the interaction layer so you can plug in game controllers, MIDI, gestures, or voice without hard-wiring each one - A built-in app SDK — the system generates its own apps based on usage patterns (the calendar and study timer were made by Prvctice itself)

It's free and open source. I also wrote a longer piece about the 14-month journey here: https://prvctice.com
