Upstream - The inbox designed for humans and agents
by•
Finally, an inbox you'll look forward to. Agents sort your messages, draft your replies, and clear the grunt work behind the scenes, all in a client so well-crafted that email feels light, fast, fun.

Early adopter of Upstream and I am a huge fan!
I have tried them all: Gmail AI features, Codex & Claude Code with MCPs, Superhuman. But the only one that really stuck has been Upstream.
My favorite feature is the emails auto draft using my voice! I find myself just pressing send 70% of the time.

@guillaume_miara Thanks for supporting us from the beginning Guillaume!

@guillaume_miara love hearing that your voice is close to spot on!

@guillaume_miara I'm so happy you like the drafts with your voice. We spent so much energy build it! Thank you!
Upstream
@guillaume_miara wow, incredible to hear!

I love the categorization, so much better than native Gmail and Superhuman. Congrats to the team!
Upstream
@flrntdg Thanks so much! Are there any other types of messages that you would like auto categorized?
Upstream
Upstream
@flrntdg thank you!
Upstream
@flrntdg BTW, what do you like about categorization that you didn't get in Superhuman?
Upstream
@flrntdg Thank you, Florent! Means a lot 🙏
Ohhh nice! Finally something that will make me enjoy writing emails 🚀

Been using Upstream in beta and the drafts genuinely sound like me, not like AI assisted. The reply’s already waiting when I open a thread. Congrats!
Upstream
@gregoireboutin We love nailing your voice, thanks for being an early supporter!
Upstream
Upstream
@gregoireboutin thanks! More to come :)
Upstream
@gregoireboutin Thank you Grégoire, it means a lot!
Upstream
@gregoireboutin thanks!
That does look great ! Is this something you are considering expending beyond emails ? (I know Slack is really the thing that's killing my productivity today...)
Upstream
@remy_z yes! Our vision is to help you get on top of everything that is important in your work life: Slack for sure, but also whatsapp, linkedin, etc.
Upstream
Looks real good !!! Can’t wait to try it
Again well done this is awesome
Quick question do the agents pull context from tools like Notion or Drive, or just from my inbox? Thanks
Upstream
@chraynaud Thanks so much! Agents can pull context from the other services you use like Calendar, Drive, Notion, and Granola. This context improves auto drafts and you can also use it when chatting with our AI.
Upstream
Upstream
@chraynaud thanks a lot! Please leave some feedback after you try it :)

@chraynaud @patryk_jeziorowski Feedbacks are the key to make upstream better 🔥
