Sauna (Wordware)

An AI coworker that learns your work by watching you do it. You write the email or evaluate the candidate yourself; Sauna supplies context from a queryable store of your mail, transcripts, docs and files; after two or three repetitions it offers to take the task over, and from then on it runs proactively in the background and hands you results to approve or edit. Their own words for the architecture: Rich Context (memory that accumulates, not a context window that forgets), Spaces (Hiring, Content Creation, Board Prep — each with its own context and rules), Recipes (cached automations, some scheduled to run overnight), Preferences, and human-in-the-loop review on everything. It reaches you through iMessage, Slack and email rather than only a web app — the homepage CTA is literally "Try on iMessage", and they publish an SMS number, +1 360 228 5583, to text it.
