How InstantReply turns a DM into a booked customer.
Not a features list — the actual sequence: how a message lands in one inbox, how the AI drafts from your own knowledge base, how a human reviews before anything sends, how follow-ups and booking handoff run themselves, and what it actually costs.
The short answer
How does InstantReply actually work?
InstantReply puts WhatsApp, Instagram, and Messenger chats in one inbox. The AI drafts replies from your own FAQs and pricing, a person approves or escalates them, and follow-ups and calendar booking handle the rest.
A customer messages your WhatsApp, Instagram, or Messenger and it lands in one shared inbox, labeled by real state: Needs reply, Follow-up queued, or Booked. The AI drafts a reply from your own FAQs, pricing, policies, voice notes, and product photos, not a generic model guessing. A person approves, edits, or escalates the draft; auto-send only covers the question types your team has already trusted. If the thread goes quiet, a follow-up sequence re-opens it once. If the customer is ready to book, InstantReply offers a real Google Calendar slot or your Calendly link without leaving the conversation. Every plan is one flat monthly or annual price, with no per-seat or per-message fees inside the inbox.
Key facts
- One inbox for WhatsApp Business, Instagram, and Messenger. No app-switching to find a message.
- AI drafts read your FAQs, pricing, policies, voice notes, and product photos before writing a reply.
- Every draft can require human approval before it sends. Auto-send only covers what you've already trusted.
- Smart follow-ups re-open quiet threads once. Booking handoff offers a real calendar slot inside the DM.
- Starter, Growth, and Pro are flat prices with no per-message fee from us. Seats are capped on Starter (1) and Growth (5), unlimited on Pro. WhatsApp starts on Growth.
STEP 1 - THE MESSAGE ARRIVES
One inbox for WhatsApp, Instagram, and Messenger.
Checking for a new lead usually means opening three separate apps. InstantReply pulls WhatsApp Business chats, Instagram DMs, Messenger threads, and a website chat widget once support turns it on for your site, into one shared queue instead, so sales and support see the same customer history, assignment, and next step before anyone replies.
Every card is labeled by its real state, not a status someone updates by hand: Needs reply, Follow-up queued, or Booked. InstantReply describes its own job in one line: “One queue for Instagram, WhatsApp Business, and Messenger. AI drafts first. Humans keep final control when the thread needs it.”
Every card, labeled by real state
Needs reply
WhatsApp - pricing question
Follow-up queued
Instagram - no reply in 2 days
Booked
Messenger - appointment confirmed
STEP 2 - THE AI DRAFTS THE REPLY
The draft comes from your FAQs, not a generic model guessing.
Add trusted answers to the Knowledge Center as manual entries or by crawling your website, and the AI only quotes from what's actually been approved. In the read-only demo, a medical spa's “Botox pricing FAQ” entry answers with the clinic's real flat rate, not an invented number.
The AI reads more than typed text before it drafts. Voice notes get transcribed. Product photos, screenshots, and receipts get described. PDFs get parsed. All of that happens on Instagram, WhatsApp, and Messenger, not just one channel.
What the AI is allowed to read
- FAQs and policies you write directly
- Your website, crawled and kept in sync
- Voice notes, transcribed before the AI replies
- Photos, screenshots, and receipts, described before the AI replies
- PDFs, parsed for pricing sheets and menus
Every draft opens with these three
STEP 3 - A HUMAN REVIEWS BEFORE IT SENDS
AI drafts. A person approves, edits, or escalates.
Every draft can stay in review mode until a human acts on it. Open a thread and there are three real buttons: Approve reply, Escalate to human, and Edit locally. Auto-send only ever covers the question types your team has already trusted, not everything by default.
Confidence scoring flags low-confidence drafts before they can send. Anything below your threshold escalates to a person instead of guessing, and you control where that threshold sits. Troll Shield, InstantReply's built-in abuse filter, blocks spam and harassment before it ever reaches the AI.
STEP 4 - FOLLOW-UPS AND BOOKING HANDOFF
Quiet leads get one more nudge. Ready buyers get a real slot.
Smart follow-up sequences (Growth and up) watch the conversations you choose. When a qualified lead goes quiet after a quote or booking question, InstantReply re-opens the thread once with one relevant reminder, and stops the sequence the moment the customer replies. No sticky notes, no calendar reminders.
When someone is ready to book, calendar booking inside DMs (Pro) checks live Google Calendar availability and offers real open slots without leaving the conversation; the slot is only confirmed after the calendar event is actually created. Using Calendly instead, the booking stays pending in InstantReply until Calendly's own confirmation arrives. Growth includes WhatsApp Flows for in-app lead capture and quote forms.

Contacts are unlimited on every paid plan, and InstantReply doesn't add per-message or per-contact overage fees inside the inbox. AI Replies are a monthly allowance built into the flat price, not billed per message: cross it and the dashboard prompts an upgrade or an add-on bundle instead of an automatic overage charge. Growth includes 5 team seats and Pro includes unlimited team seats, neither billed as a separate line item the way ManyChat charges $25 per extra seat. Annual billing saves up to 17%. Meta's own WhatsApp delivery fees are billed directly to your Meta account and are never marked up by InstantReply -- see what Meta actually charges for WhatsApp messages for the full rate breakdown.
