Nunatak — Above the Waterline

Field notes

Nunatak describes an email-first filtering layer rather than a replacement inbox: material below the threshold remains searchable, while users can mark missed items to refine the signal boundary. The project is explicitly single-user, not a shared queue or helpdesk, and the homepage says there is no ship date or product login yet. Visitors can subscribe for a trial announcement or occasional posts about the underlying ideas.
