What it does
A turnkey self-hosted diarization service that runs fully offline: drag files in over SSH or the web UI, get transcripts attributed per speaker, summaries via Ollama, and full-text search across everything. Nothing leaves your infrastructure, which is the whole point for regulated work. The flip side is that a searchable who-said-what archive needs a retention policy and an access list decided up front — and that diarization makes mistakes, so it isn't evidence. GPL-3.0.

transcriptionstream FAQ
- Is transcriptionstream free?
- Yes. It runs on your own machine, so there is no usage-based cost either.
- Do I need to install anything or write code to use transcriptionstream?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does transcriptionstream work on a phone?
- No. It needs a computer.
- Can transcriptionstream run offline?
- Yes. Everything happens on your own machine, so your data is never sent to an outside server. That makes it usable for material you cannot share externally.
- Can I use transcriptionstream commercially?
- The licence is GPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
