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.

Makes me love email again 😍

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.
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.

@bengeekly We've got an iOS app, check it out 🙂
Daily driver here. Dictation mode lets me just talk and it writes. And "needs reply" is brilliant: the draft is already there waiting, so I'm never staring at a blank page, but I stay in control of what actually sends. Rare to find AI email that assists without taking over. Congrats to the team.

@benjamin_lalanne1 We appreciate that Benjamin! Also there are quite a few of us in the office that use dictation too 🗣️🗣️🗣️
I’ve been using Upstream and what really stands out is how natural the drafts feel — they actually sound like me, not like a generic AI reply. Opening a thread and already having a solid response waiting there saves a surprising amount of time. The follow-up nudges are also genuinely useful for keeping important conversations from slipping through the cracks. Congrats on the launch — this is one of the few AI email tools that feels built for real daily use.

@greg_lpz Thanks so much Grégoire!! Are there any features that would help make AI replies even better for you?

Certainly the most promising email client in a while!! The onboarding will blow your mind, it feels like Upstream has been knowing you forever, and it writes emails exactly like you. Emails are cool again!

@aureliengeorget Thanks so much Aurélien! We worked hard on refining the onboarding flow, I'm glad it resonated 😄
Great product! I tested it and I'm pleasantly surprised by its effectiveness! It manages my emails very well, with highly relevant suggested replies that save me time—just reread and send! I haven't tested the collaborative aspect with my team yet, but the promise is there: working together on emails to provide the best possible responses, all while staying aligned with everyone, and all powered by AI. I highly recommend it!

@johan_p_ Thanks a ton Johan! We really appreciate it. Let us know if there are any features that would make things easier.
Looking sleek. I haven't been able to manage my inbox since Google discontinued Inbox 💔 so I might try upstream. Tech has changed, time for my 999+ unread emails to go.
Upstream
@syswarren Yes, give Upstream a go! We'd love to hear your feedback 😄
Upstream
I used to love Google Inbox too, but now I enjoy doing email 100x more with Upstream 😏
Great product. Much better than any other inbox app I’ve tried!
