Hey Product Hunt 👋
I'm a solo developer from Japan. I built Replyy for one moment: the email you keep putting off — a pricing pushback, a complaint, a long thread where someone asks "so where did we land?"
You can't fire back a template, so you scroll up, reread everything, and try not to contradict what you promised three replies ago. That rereading is where the time quietly goes.
"AI email tool" sounds crowded, I know. The real difference: Replyy reads the *whole* thread, not just the last message. Paste a back-and-forth and it works out what's agreed, what's open, and the other person's tone — then drafts a reply with that context. It also flags priority and risk before you write.
No login. Paste an email, get a reply you can review and send. It never sends for you, and pasted emails are never stored or used to train any model.
Free to try (5 drafts/day). Pro is $9/mo and live now — thread mode, tough-email mode, saved templates.
One honest note, since I build in public: I'm raising Pro to $12/mo about a month from today. Sales-focused tools like Lavender run $29–69, so $9 started to feel almost too cheap to trust. But anyone who joins at $9 stays at $9 for good — early folks get the best deal, permanently.
I'd love your honest take: what's the one email type you dread replying to most? I want Replyy to get great at exactly those.

@nanimono_masa Congratulations on the launch! Replyy solves a very real problem for many who struggle with "What do I say?" The fact that it looks at the whole thread is smart - you know the reply is going to have the right context.
Good move up on the price point - there's a delicate balance on trust and pricing.
For me, the follow-up email after I send a proposal is the hardest - you want to follow up but you don't want to sound cheezy or salesy!

@anna_ludwinowski Thank you so much, Anna 🙏 And you just answered my question perfectly — the post-proposal follow-up is exactly the kind of email Replyy should be great at. That "I want to follow up but not sound salesy" tension is such a real, specific pain. I'm noting it down as something to make Replyy genuinely good at.
Really appreciate you taking the time to stop by and share this — especially on your own busy schedule. And thank you for the earlier advice; leading with the problem instead of the tech made a real difference in how I framed everything today.
Rooting for your September launch 🙌

Honestly the risk flagging caught me off guard, like it actually pointed out a line in my draft that could've come across wrong. Free tier covers single emails which is honestly enough for most days.

@baldwin_camp This genuinely made my morning 🙏 The risk flagging is the feature I was most nervous about — it's easy to build something that just says "looks fine!" — so hearing it actually caught a line that could've landed wrong means a lot. That's exactly the moment it's built for.
And yeah, that was the bet with the free tier: most days are single emails, so those should just be free. Really appreciate you trying it and taking the time to share this 🙌

Pasted a long client thread in and the risk flag caught a pricing change request I would have missed. Reply saved me from a sloppy reply for sure.

@quentin_ramsay This is exactly the scenario I built thread mode for 🙏 A pricing change buried three replies up is the kind of thing that's so easy to miss when you're moving fast — and catching it before you hit send is the whole point. Really glad it worked when it mattered.
Thanks for actually pasting a real thread in and putting it through its paces — that means a lot 🙌

Pasted a tricky follow-up I'd been avoiding and the priority flag caught a detail I'd actually missed. Feels like having a second pair of eyes before hitting send.

@wolfgang_smith "A second pair of eyes before hitting send" — honestly that's a better way to put it than anything I've written 🙏 That's exactly the feeling I was chasing. The draft matters, but catching the thing you'd have missed is where it earns its place.
And "a tricky follow-up I'd been avoiding" is the exact moment I built it for. Really glad it helped when it counted — thanks for giving it a real try 🙌
