The email you're dreading? Paste it. Get a reply you can actually send.
Reply faster. Reply safer.
Every salesperson knows the feeling. You open your inbox and there it is — the email you've been putting off. A pricing pushback. A complaint. A three-round thread where someone asks, "So where did we land on this?"
You can't fire back a template. It would read as cold, or worse, contradict something you already agreed to. So you scroll up. You reread the whole thread. You try to remember what was promised, what's still open, and how annoyed the other person actually is.
That rereading is where the time goes. And the faster you rush it, the more likely you are to say something that doesn't match what you said last time. For a salesperson, that's the scary part.
Two problems, one paste
I'm a solo developer, and I built a tool called Replyy to take this specific weight off. You paste the email you received, and it drafts a reply you can review and send. No login. No signup. Open the URL and paste.
But two things about difficult emails turned out to matter more than raw speed, so I built for both:
1. It tells you what you're dealing with before you reply. Paste an email and Replyy flags the priority and the risk — is this a routine reply, or is this the kind of message where one wrong word loses the deal? You see the read before you write. That's the "reply safer" part.
2. It reads the whole thread, not just the last message. Most AI reply tools only see the final email. But real business email is layered — past commitments, unresolved points, the other person's temperature, all stacked across many rounds. Replyy's thread mode lets you paste an entire back-and-forth, and it works out who said what, what's been agreed, and what's still open — then drafts the reply with the full context in mind.
A salesperson in Japan tried an early version and kept telling me how much easier it made the work — that it felt almost silly how much effort he used to spend. That's the bar I'm building toward — not "neat AI demo," but "this just got off my plate."
This isn't for every salesperson
Let me narrow it honestly.
Replyy helps if you live in this gap: the quality of your replies can't drop, but the time you spend on them really needs to. If email is copy-paste for you, or you don't spend a second on replies, you won't need it.
But if "I want to reply well, and I have no time" describes your day — it's worth ten minutes of your own to find out.
Free, and built in public
I'm building Replyy in the open, shipping and sharing as I go. Here's the honest state of it:
Free, no account:
Draft replies to single emails (5 per day)
Industry modes for SaaS sales, inside sales, dev sales, consulting, and CS
English and Japanese, with adjustable tone and formality
Pasted emails are never used to train any AI model (per the API provider's terms) and never stored on the server
It never sends anything for you — you always decide what goes out
Pro (for heavier use):
Thread mode — paste a long back-and-forth and reply with full context
A mode for the emails you dread most — complaints, chasing, awkward asks
Saved templates and signatures
100 drafts a day
Pro is planned at $9/month. If you want to try thread mode now, reach out through the contact form and I'll send a key during the beta.

I'm not handing you a finished product. I'm looking for people to help shape it. If you try it and think "this is close, but —", that "but" is the most useful thing you could give me. Paste an email, see what comes back, and tell me where it falls short.
I'm building Replyy as a solo developer, in public, around one idea: give salespeople their time back. You can follow the build on X @nanimono_toyama.
