inbound sales, on

Reads the message and sends it to the right Supervisor Agent
Matches the specific request to one of its Specialist Agents
Using its goal, instructions, guardrails, knowledge base, and connected apps
Loops in the right person the moment a human should take over
One system.
Every message
handled.
Every message moves through a team of AI agents. The Intake Agent reads it first and routes it to the right Supervisor Agent — Sales, Support, Residents, whatever you've set up. That Supervisor Agent then picks the exact Specialist Agent for the specific request.
A pricing question goes to a different Specialist than an inventory question — even inside the same Category. That layered routing is why every answer is accurate, not generic.
Each Specialist Agent is a
complete set of instructions.
Its goal, how it should respond, what it must never do, and when to pass to a person — plus which apps and docs it can use. You write every line.
The Sales Supervisor Agent above holds three Specialist Agents, each handling one kind of request.

It knows your business
before you write a word.
Point Reply Flow at your existing WhatsApp and email history. The import wizard pulls in every past conversation, de-duplicates and merges the threads, and extracts your contacts and companies into a full relational CRM.
Then AI classifies everything — tags, lists, statuses, custom fields — and pulls the memories that matter onto each contact. You start with context, not a blank slate.

Specialist Agents
Each Specialist Agent is your step-by-step instructions for one kind of request. You write the rules; it follows them.
"When someone asks about hours, check the schedule and reply with today's status." — that's a Specialist Agent. You write it once; it runs forever.
Connected Apps & Custom Tools
One-click integrations with Shopify, WooCommerce, Airtable, Google Sheets, and more. For any other app, create a custom tool in minutes — no developer needed.
AI checks your Shopify inventory and replies with stock status. Or creates an order, updates your CRM, logs a task in your project manager — all mid-conversation.
Knowledge Base
Upload your help guides, policies, menus, price lists — anything your team references. The AI understands context, not just keywords, so it finds the right paragraph every time.
Someone asks about your return policy. The AI pulls the exact clause from your policy doc — not a generic summary, the precise answer for their situation.
Memory Agent
After every conversation, the Memory Agent extracts important details — preferences, requirements, past issues — and saves them to the contact's profile automatically.
A returning customer messages you. The AI already knows their last order, that they prefer USPS, and that they buy in bulk. No one had to tag or log anything — it learned on its own.
Not just answers.
Actions.
A reply is often only half the job. Reply Flow's agents don't just say the right thing — they do it: run workflows, take payments, manage the calendar, and understand whatever the customer sends.
Explore what agents can do →Automations that fire on their own
Trigger → condition → action. When an order ships, a form comes in, or a keyword appears, Reply Flow runs the workflow you defined — sending messages, creating tasks, updating records, or looping in a person.
Commerce, mid-conversation
Place orders, generate payment links, and process refunds without ever leaving the chat — the agent handles the transaction as part of the reply.
Booking & scheduling, handled
Book, reschedule, cancel, and set recurring appointments. The agents are trained for the whole calendar dance and stay in sync with your team's availability.
Understands whatever they send
Reads voice notes, PDFs, and images to grasp what a customer means — and sends back the right document or image when a reply calls for it.
One prompt for everything
A dedicated Specialist Agent for every situation, each with its own instructions, rules, and apps
Answers from general knowledge
Answers from your knowledge base, your apps, and your customer's history

Routes to the right person, nudges if they're slow, keeps the customer informed
No memory between conversations
Learns from every conversation and remembers each customer
Can't take actions
Creates orders, updates your CRM, logs tasks — mid-conversation
This is not
a chatbot.
Most AI tools give you one prompt and hope for the best. Reply Flow gives you a complete system where every part works together — and you control all of it.
TYPICAL CHATBOT
REPLY FLOW
AI handles it —
until you need to.
You decide, situation by situation, when the AI should step aside. When it does, your team picks up right where it left off.
The reply is just the start.
When a conversation ends, more agents go to work in the background — so your records stay current and your follow-ups happen, without anyone touching a thing.
Memory Agent
Extracts what mattered from the conversation — preferences, requirements, past issues — and saves it to the contact, so the next message starts smarter.
CRM Agent
Keeps your CRM current on its own: creates, merges and de-duplicates contacts; applies tags and labels; updates custom fields, statuses, lead scores and pipeline stages; and assigns each conversation to the right teammate.
Task & Calendar Agent
Creates tasks, reminders and follow-ups from what a conversation promised, and books them straight onto the calendar — so nothing quietly falls through the cracks, and it nudges you when something's due.
There's a whole platform
behind the replies.
Reply Flow runs your front line — but it's also where you analyze, reach out, and manage the work your team still owns.
Analytics you can ask
See everything happening across conversations — and just ask the AI anything about your data, in plain language.

Agents that watch your group chats — alerting you or replying when a topic comes up, you're mentioned, or someone asks a question.
Learn more →Shared team inbox
For the conversations your team handles: shared inboxes, assignment, and full conversation management — side by side with the AI.

The things you'd
ask on a sales call.
Couldn't find yours? Email [email protected] — a real person replies in under an hour during business hours.
How fast can we actually go live?
About an hour for most teams. Connecting your Gmail and WhatsApp takes five minutes. The rest is writing your first scenarios — the situations your customers actually run into, and how you'd want them handled. We're happy to walk you through it; no onboarding call required.
Will the AI go off-script and embarrass us?
No. The AI only replies when a message matches a scenario you've written. You set the rules; it works inside them. For anything you didn't plan for — refunds, VIPs, anything ambiguous — it stays silent and your team handles it.
Will my WhatsApp number get suspended?
No. Reply Flow runs on official, fully-compliant WhatsApp infrastructure. Opt-in flows, message templates, and the 24-hour reply window are managed for you — so the things that get accounts banned (cold-blasting strangers, sending after the window without an approved template) can't happen by accident.
Will my emails go to spam?
No. Reply Flow sends from your own Gmail or Google Workspace account — deliverability is exactly the same as when you write the email yourself. Your domain, your reputation, your inbox placement. Nothing relays through our servers.
How does my team handle the conversations the AI doesn't?
The conversation goes to the right person — by topic, by workload, or to a specific teammate. If they don't reply in time, the system nudges them, escalates if needed, and keeps the customer informed. Everyone sees who's handling what.
Where is our customer data, and is it safe?
Your conversations, contacts, and docs live in your private Reply Flow workspace — encrypted, isolated from every other company's, and never used to train any model. SOC 2 Type II is in progress; available now under NDA.
Can the AI take actions, or just answer questions?
Both. It can look up an order in your store, check stock in your spreadsheet, or validate a coupon — then reply with what it found. It can also place orders, send payment links, process refunds, and book, reschedule or cancel appointments on your calendar. You connect the apps you use and choose which scenarios are allowed to use them.
Do I have to build my CRM before I start?
No — Reply Flow builds it for you. Point it at your existing WhatsApp and email history and the import wizard pulls in past conversations, de-duplicates and merges threads, and extracts your contacts and companies into a full relational CRM. Then it classifies everything (tags, lists, statuses, custom fields) and saves the memories that matter to each contact. You start with context, not a blank slate.
Can it do more than reply — like follow-ups and automations?
Yes. Beyond replying, Reply Flow runs trigger → condition → action automations (when an order ships, a form comes in, or a keyword appears, it fires the workflow you defined), creates tasks and calendar events from what a conversation promised, and nudges you when something's due. It's a full customer-service and inbound-sales system, not just an auto-reply.
Can it handle voice notes, PDFs, and images?
Yes. The AI listens to voice notes and recordings, reads PDFs, documents and images to understand what a customer means — and sends the right document or image back when a reply calls for it.
Can I cancel anytime, or am I locked in?
Cancel anytime. No annual contracts, no early-termination fees. If you stop, your data is yours — we'll help you export it.
What languages can the AI reply in?
Whichever language the customer wrote in. The AI reads the message, matches it to a scenario, and replies in the same language — without you toggling anything.
Can my team review AI replies before they go out?
Yes. The AI can prepare a reply and queue it for a teammate to approve with one click — useful while you're getting comfortable, or for sensitive conversations where you want a human eye first.
