Meeting Concluder Build status

This application can record and then summarize meetings automatically. An advice is added at the end of the summary, which can then (optionally) be sent to a Slack channel of your choosing.

Created in connection with the 2023 Hackdays.

Getting started

  • Install the required dependencies (portaudio, ffmpeg and Go 1.16 or later).
  • Configure your Slack web hook URL either as the SLACK_EBHOOK_URL environment variable, or as slack_webhook = "YOUR SLACK WEBHOOK URL GOES HERE" in ~/.config/concluder.toml.
  • Configure your OpenAI API Key either as the OPENAI_API_KEY or OPENAI_KEY environment variable, or as openai_api_key = "YOUR KEY GOES HERE" in ~/.config/concluder.toml.
  • Make sure that you have a working microphone.

Clone the repository and run the server (which includes a frontend):

git clone https://github.com/schibsted/meeting-concluder.git
cd meeting-concluder/cmd/backend/backend
go build
./backend

Then visit http://localhost:3000.

A double clap can be used to stop the recording.

Note that the current maximum audio file size for the transcription API is 25 MiB, which is not a lot! Pull requests for adding batching are welcome.
