ArtCopy mobile feed showing a watercolor street scene by @sketchyfish7

Artists upload process videos of their work. Other users watch the process and see the final drawing, then attempt to recreate it from scratch. After submitting, they compare their version side-by-side with the original — and the community votes on the results.

What we built
  • Native iOS and Android drawing canvas built with React Native Skia
  • Realtime multiplayer drawing game on shared-and-swapping canvases
  • TikTok-style video feed with autoplay, gestures, and native video pipeline
  • AI moderation (OpenAI Vision + Anthropic) with auto-takedown and creator notification

How we work
  1. 01

    Direct access

    Work with the person writing the code. No project managers, no account executives, no triage layer between you and the engineer.

  2. 02

    Your code, your infrastructure

    Git repositories in your GitHub organization. Deploys to your Vercel, your Supabase, your App Store account — never ours.

  3. 03

    Updates when there's work to show

    A short video by email whenever there's progress — a fix, a feature, a polish pass. No scheduled check-ins. You see the work when it ships.

  4. 04

    Fixed-fee scope

    Project estimates are a single number, not a range. Scope changes are discussed, priced, and agreed before we touch the code.
