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.
Upstream
Hey Product Hunt! 👋 Louis here, co-founder of Upstream.
When I was at Algolia, I was drowning in 200 emails a day. I was never sure where to focus, and getting through my inbox took forever. I knew it didn’t have to be this way. Instead of creating a new messaging protocol, I bet on rethinking the tool everyone uses: email.
We built the first email client where agents do real work alongside people. We designed Upstream to be easy to pick up and fun to use.
📥 Take the noise out of email
Agents automatically triage your inbox, separate signal from noise, and surface only what deserves your attention
✍️ Every reply starts with a draft
Upstream drafts replies for every conversation that needs one. It also changes your voice based on who you’re talking to and the context of the convo
⏰ Never miss a follow-up
Agents track open loops and remind you when needed, making sure important conversations don't fall through the cracks
🔎 Ask anything about your work
AI can instantly find information across your inbox and connected tools: receipts, meeting notes, introductions, decisions, conversations, and more
🔗 Bring all your context into your inbox
Agents use information from tools like Notion, Calendar, Drive, Granola, and other sources to produce better answers and drafts

Came over from Superhuman and haven’t looked back, the drafts actually sound like me. Congrats!

@mvaxelaire What would be the top features you'd want? 🤓
The interesting problem with a shared human/agent inbox isn't the UI, it's attribution and handoff. When an agent drafts or sends something on my behalf, I need to know exactly what it touched, what it decided autonomously versus what it queued for my review, and what happens when I disagree with a choice it already made. Does Upstream have a clear model for that, or is the agent more of a drafting assistant that still requires explicit approval before anything goes out? Also curious whether this is built on top of existing mail providers like Gmail and Outlook, or whether you're asking people to route actual email through a new address.

@fberrez1
We totally agree that control and final decision should remain in your hands. The agents work for you and nothing gets sent without your approval. Upstream works with your existing gmail address and keeps everything in sync with your Gmail account.
TBH I find the attribution/handoff problem fascinating, especially as agents are going to gain in capability. Do you have a take on what the right approach should be here?
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 😄

Total game changer. Congrats team for the launch!
Upstream
@adrienm Thanks Adrien!
Love your promise! Out of curiosity: every other email tool say they sound like me these days, what makes you claim you are better here?
Upstream
@geoffroy_de_cooman1 As soon as you join, Upstream creates a custom writing agent that analyzes writing style, tonal shifts, lowercase usage, abbreviations, greetings, sign offs, and more for each audience. We also adjust the tone of AI drafts depending on the context of the current conversation. On top of that you can even customize the prompt to fine-tune exactly how you want to sound.

congrats team!
I've a quick question. How can I edit the soul or voice of the agent when writing email draft? Can I create multiple profiles, eg. when writing to a team member, a lawyer, a customer, or a VC?
Upstream
@jelorillon Thanks Jean! You can edit the prompt for your voice by going to Settings > Configure Agents. You'll be able to tweak your global writing style prompt as well as the prompts for each audience. You can also create a custom audience and define your voice for it.
Just curious what are your most common audiences?
