Show HN: Herald – Local-first terminal email client

Hi folks,

Some time ago I tried to find a way to clean up my 10k emails inbox and could find anything which worked for me. So I built built my own tool which evolved into a client.

More that out of necessity but for fun add semantic search, LLM based tagging, and clean up rules through Ollama.

It has a demo mode to try without configuring anything.

On Mac:

brew tap herald-email/herald brew install herald herald --demo

With Go:

go install github.com/herald-email/herald-mail-app/cmd/herald@latest herald --demo

The DEMO uses pre-populated synthetic data so no risk for your inboxes.

Any feedback will be highly appreciated.
