Make AI work visible on your desk. OpenPromptlet is an open-source prototype with four push rotary knobs and a round ESP32-S3 display. Watch host-reported task checkpoints in a real Codex browser-review demo, then build your own with enclosure files, parts and firmware. Next: improve portable use with the OpenPromptlet companion app. Portable support is planned, not released.

I built OpenPromptlet because I wanted a physical way to see what an AI task is doing. It has four push rotary knobs and a round ESP32-S3 display, in an enclosure you can print yourself.
Watch the 56-second demo: https://openpromptlet.com/#task-...
The film shows a real Codex browser review: host-reported checkpoints appear on the physical display while Codex works on the connected computer. It uses OpenAI Cedar AI narration, original music and labelled AI-retouched product stills. On-device voice and a knob-triggered task launch are not demonstrated.
The enclosure files, parts list, firmware and setup guide are open source. This is a working bench prototype, with the enclosure and integrations still evolving.
Next, we’re working toward easier portable use with the OpenPromptlet companion app: simpler connection and setup, and progress updates away from the workbench. Portable support is planned, not yet verified or released.
What would you most want to see on a small physical display while an agent works?
