OwlU

OwlU is a desktop email client with an AI agent layered on top, aimed squarely at people who run their business alone. Instead of juggling Gmail, Outlook, Naver Mail, company webmail, and custom-domain inboxes in separate windows, you connect them all and read them in one place. On top of that unified inbox, an agent summarizes long threads, surfaces what the agent actually did inside the mail UI, and keeps a running context summary so you do not have to re-read a 12-message thread to remember where things stand.

The second half of the product is automation. You describe a workflow in natural language — auto-classify and archive newsletters, pull meeting details out of invitations into a calendar, draft replies as saved drafts, save attachments from specific senders to a local folder, generate a daily processing report, or periodically crawl a web page into a spreadsheet — and the agent runs it. Critically, you choose how much autonomy it gets: fully automatic, semi-automatic, or manual, with approval buttons and a visible run history of total runs, success rate, and failures. A third layer maps the people behind your mail, showing who you correspond with most, which organization an address belongs to, and how the relationship flow has moved over recent months.

The company positions the product around trust signals rather than feature count: it advertises Google CASA Tier 2 certification, a verified Google OAuth app, and a notarized Apple installer, which matters when you are handing an agent OAuth access to work mail. Distribution is a downloadable desktop app for macOS and Windows. Pricing is presented as completely free on the homepage, with no public paid tier listed; as with any free agent product, verify current terms and data-handling details on the site before connecting sensitive accounts.
