AI support agent for small SaaS teams
Most support tools help you manage emails. ReplyOS handles them.
A programmable support agent that reads every email, matches it to your rules, and acts—creating tickets, posting to Slack, drafting replies—in under 4 seconds.
See how it works→Deep Discovery report request
Hi guys, I've conducted a new Deep Discovery research for a biking brand. Let me know if you need any additional details.
You built something people love.
They deserve a faster answer than you have time to write.
You're a small team. Support isn't a department—it's whoever has time between community calls and content drops. You've got 53 unread messages, half of them asking how to access the member portal, and somewhere in there is a founding member who feels ignored.
You tried Intercom. Too heavy. Zendesk? Enterprise theater. You don't need a ticketing system with 200 features and a dashboard that makes you feel like you're running an airline. You need someone—something—to actually handle the emails.
Not triage them. Not tag them. Handle them. Read them, understand them, do the right thing, and reply.
One inbox. Infinite rules.
Set it up once. The agent runs your support inbox while you build your product.
Connect
Point your support email at ReplyOS, or use a free hosted address. Your inbox is live in minutes.
Configure
Build response rules in plain language. Define what the agent should do when a specific type of email arrives: reply, escalate, create a ticket, hit an API.
Act
The agent reads every email, matches it to a rule, and executes: drafts replies, creates records, posts to Slack, fetches data. All automatically.
Review
An audit log shows every decision. Override anything. Tune rules based on what you see. The agent gets smarter as you refine.

Before / After
Alex got his Tuesdays back.
Alex is the co-founder of a community marketing startup. He handled report requests himself between investor calls and product strategy. Every week, the same asks: "I've finished a Deep Discovery study—can you generate the report?" "The client needs their insights deck." "Can you pull the data for our presentation?" He was spending 10 hours a week logging into the product and manually running reports.
On a Tuesday afternoon, he configured 8 rules in ReplyOS. Discovery report requests automatically trigger report generation and notify the requester when it's ready. Client insight requests pull the data and compile the deck. Presentation exports get formatted and sent directly.
He hasn't manually generated a report since.
The audit log shows 340 requests handled automatically in the past month. Response time went from "whenever Alex had a chance" to under 2 minutes. Two clients mentioned how fast turnaround felt. One of them signed a bigger contract.
Rules that actually do things
Plain language conditions. Real actions. This is what the rule builder looks like.
