Upstream is an email client that separates the humans from the noise. AI agents sort your inbox, draft replies, and handle the grunt work, while tools like Notion, Granola, and your calendar get their own space rather than clogging up your actual conversations. Louis Lecat built it after drowning in 200 emails a day at Algolia
π₯ Our Take: Upstream's whole point is that your inbox stopped being for people a while ago. Half of what shows up is machines talking to you. GitHub, Notion, your calendar, now your AI agent, all sitting in the same list as an actual email from an actual person. Louis Lecat came out of Algolia, which is basically one long exercise in finding the thing you need while everything else is shouting, so this is a problem he already knew how to think about. Google will get around to putting AI in Gmail, but Gmail doesn't know what's in your Notion or your Granola notes, and Upstream does.
