Hey Product Hunt! 👋 I'm Tom, founder of HumanInbox. The problem I've been running SaaS businesses for 10 years. Every day: too many emails, replies I forget to send, follow-ups I never get around to. I didn't want another inbox tool. I wanted someone to handle it for me, the way a real assistant would. So I built it. What is HumanInbox? HumanInbox is your AI email assistant, available directly on Telegram & WhatsApp. It learns your tone, drafts replies for you, sends follow-ups automatically, and keeps your calendar in sync: all without opening your email client. No new app to learn. Just message your assistant like you would a real one, from your phone. What makes it different? 🎙️ Voice notes: Send a voice note, HumanInbox drafts the reply ✍️ Drafts in your tone: It learns how you write and sounds like you 🔔 Automatic follow-ups: Never miss a reply again 📅 Calendar sync: Schedule meetings without leaving your phone 📱 Lives on Telegram & WhatsApp: No new app, no new habit to build Who is it for? Solopreneurs and busy executives who get too many emails and have no one to handle them. If you've ever wished you had an assistant just for your inbox, this is it. I use it every day myself. $99/mo. Happy to answer any questions! 🙏

Congrats on the launch, Tom. I like the "no new app" approach via Telegram/WhatsApp is a smart friction-killer.

One quick note since HumanInbox reads and drafts from personal inboxes: make sure your Privacy Policy explicitly states how email content is processed, stored, and whether it's used for model training. Apple and enterprise security teams scrutinize this heavily for email-access apps.

Not trying to sell anything, just a heads-up from someone who reviews these policies daily.

I like HumanInbox's seamless integration of emails in my WhatsApp. Just curious whether the email sent would be formatted correctly, because in your demo, I see a block of text instead of a properly formatted message in HumanInbox's response.

@jinhao_bai2 Good question! We are using the Gmail API, so the format fits really well with the email. The demo it's not a real email :)

"No new app to learn" - this is such an underrated product decision. As a solo founder drowning in email, the idea of just messaging an assistant on WhatsApp instead of opening another dashboard is really appealing. How are you handling the trust barrier? Giving an AI access to your inbox feels like a big ask, even when you desperately need the help.

Do you compile tone into an idiolect from ingesting emails as context, or is this learned over time?

Oof $100 a month is definitely cost prohibitive outside of ‘executive’ use, as advertised, no notes.

But how does this stack up to superhuman?
