HeyRudy
A focused, single-user version (screen capture → event detection → TTS overlay) is realistic for a capable developer to build and run; reproducing HeyRudy's full low-latency polish, multi-voice persona library, and cross-platform experience is larger work best left to the vendor.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All HeyRudy alternatives, with the arithmetic →
What a replacement has to do
- Continuously capture the user's screen, run lightweight vision/event detection to recognize in-game states (kills, deaths, loading screens, being stuck), map detections to prewritten prompts and personality personas, synthesize short utterances, and play them back as audio while rendering an overlay or small picture-in-picture UI.
What it still won’t have
- Production polish (latency optimizations, robust voice switching, polished personalities)
- Large voice library and curated persona tuning
- Cross-platform mobile camera-first experience and native mobile optimizations
- Scale handling, analytics, and platform-specific integrations (Twitch/YT direct hooks)
- Legal/moderation workflows and refund/billing ops handled at scale
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal AI gaming sidekick web+desktop app using React for the frontend, Electron for desktop screen capture, a Python FastAPI backend, PostgreSQL (optional) for user accounts, and OpenAI-compatible APIs for instruction-following plus a TTS provider (e.g., ElevenLabs) for voice. Core features in scope: (1) user sign-up/sign-in and a one-seat subscription check (Stripe sandbox), (2) screen capture from desktop via Electron and frame transport to backend over WebRTC/WebSocket, (3) simple rule-based + small CNN classifier to detect common events (death, kill, loading), (4) prompt orchestration mapping events→utterances with two persona filters (Nice/Bad), (5) streamed low-latency TTS playback and a picture-in-picture overlay UI, (6) error handling, logging, and unit/integration tests for capture, detection, and TTS playback. Out of scope: large-scale analytics, multi-language tuning beyond English, mobile camera-first UX, large voice library, and production deployment automation. Deliver a README with setup steps, dotenv configuration for API keys, CI test commands, and basic load/error scenarios.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
