Open source

Every part of OpenScribe is open, from the circuit to the summary. Build it, improve it, keep it.

The ethos

The person who records the audio should own it. That principle runs through the whole project. Nothing depends on a service that can be taken away, and nothing traps your recordings in a format only one company can read.

• Own your data. Audio and transcripts stay on your storage.
• No lock-in. Open hardware, open firmware, open API.
• Reproducible. Anyone can build the whole thing from the documentation alone.

What is open

• Firmware for the ESP32-S3 device: recording, storage, sync and the on-device API.
• Server that ingests recordings and runs transcription and summaries.
• Mobile app for Android and iOS.
• Hardware design and a bill of materials you can order.
• 3D-printed case, parametric so it fits your exact build.

The firmware and software are copyleft, the hardware is open-hardware licensed, and the documentation is share-alike. Improvements stay open for everyone.

Build one

Off-the-shelf parts, a printed case, and a server you run. An ESP32-S3 with memory, an I2S microphone, a microSD card, a battery and a charging circuit. The firmware builds with common tooling, the case prints in a couple of hours, and the server runs on anything from a home NAS to a small cloud box.

The code is opening soon

The public repository is being prepared for release. Register your interest and we will let you know the moment it opens, so you can build, fork and contribute from day one.
