<p>Hey Product Hunt! 👋 Louis here, co-founder of Upstream.</p><p></p><p>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.<br><br>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.&nbsp;</p><p></p><p><strong>📥 Take the noise out of email<br></strong>Agents automatically triage your inbox, separate signal from noise, and surface only what deserves your attention</p><p></p><p><strong>✍️ Every reply starts with a draft<br></strong>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</p><p></p><p><strong>⏰ Never miss a follow-up<br></strong>Agents track open loops and remind you when needed, making sure important conversations don't fall through the cracks</p><p></p><p><strong>🔎 Ask anything about your work<br></strong>AI can instantly find information across your inbox and connected tools: receipts, meeting notes, introductions, decisions, conversations, and more</p><p></p><p><strong>🔗 Bring all your context into your inbox<br></strong>Agents use information from tools like Notion, Calendar, Drive, Granola, and other sources to produce better answers and drafts</p><p></p><p>👉 As a special thank you to the Product Hunt community, you get one free month of Upstream Pro if you sign up at <a href="https://www.upstream.do/?utm_source=producthunt&amp;utm_medium=launch&amp;utm_campaign=launch&amp;utm_content=firstcomment" target="_blank" rel="nofollow noopener noreferrer">upstream.do</a> and use the code PH26! 👈</p><p></p><p>We are all so excited to hear what you think!

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

<p>Where do you guys draw the autonomy line on triage vs sending? Those two might fail completely differently IMO. Anyways, great work!</p>

<p>I have too many email accounts. Plural. And they are all overlapping and somewhat out of control (honesty here). This allows me to scan them easily and action on what needs actioning without it being a total headache. Thanks for creating something so user-friendly as well as accurate to my own voice! </p>
