Firebender vs Piano Genie

Firebender is an Android-native coding agent delivered as a JetBrains plugin for Android Studio. It writes features, runs tests in the emulator, and fixes issues on its own, so Android developers can stay inside the IDE they already use.

The plugin hooks into Android Studio refactor tools, the debugger, and logcat rather than acting like a generic chat window pasted on top. You can paste a Figma link to generate Jetpack Compose UI that fits an existing design system, or spin up custom agents and sub-agents for workflows like crash triage and code review.

Engineering teams at Instacart, Netflix, DoorDash, Slack, and other companies use it for daily Android work. It supports frontier models from OpenAI, Anthropic, Google, and xAI, plus bring-your-own-key options, with SOC 2 Type II and ISO 27001 certification and a zero data retention policy for uploaded code.

Piano Genie is a browser toy that turns eight buttons into a full 88-key piano using a neural network trained on classical performances. Press keys 1 through 8 on your keyboard, the home row, or colored touch blocks, and the model picks plausible notes so you sound like you know what you are doing. The space bar works as a sustain pedal.

Guitar Hero maps fixed note charts; Piano Genie lets you improvise freely. The model was trained on roughly 1,400 virtuosic performances from the International Piano-e-Competition, so the output skews classical rather than pop or jazz. Google Magenta published the research at ACM IUI 2019 and open-sourced the training code.

Anyone curious about music ML who does not read sheet music can use it for a few minutes of fun. The Glitch-hosted demo shut down with Glitch platform changes, but the creator still hosts a working copy at chrisdonahue.com.
