AgentReply — Build Your Own AI Agent for WhatsApp, Instagram & the Web

What is AgentReply?

Short answer? AgentReply is the easiest way to launch an AI agent that replies on WhatsApp, Instagram, Messenger and your website — in five minutes, with no code. Longer answer below.

We're a software-as-a-service platform built for solo founders, agencies, customer-support teams and growing brands who need their messages answered now, not in three hours. Pick a persona, paste your knowledge, choose a voice, connect a channel — and your AI agent is live. No engineers. No rebuilds. No monthly retainers from a chatbot agency.

Whether you run a restaurant taking reservations on WhatsApp, an e-commerce store answering product questions on Instagram DMs, or a SaaS company that wants instant on-site chat support, AgentReply gives you a production-ready AI agent without writing a single line of code.

Can AgentReply really reply on WhatsApp?

Yes — and we mean really, not "kind of." You can connect a Meta WhatsApp Business Cloud number (the official, production-grade route) or start with a Twilio WhatsApp Sandbox number for testing. Your AI agent replies natively in the WhatsApp thread your customer already uses, remembers each contact's name and history, and follows whatever intake rules you set up.

Most teams have their first WhatsApp reply going out within an hour of signing up. That's not marketing speak — it's our average onboarding time, measured across thousands of agents.

Best AI Agent Features

• WhatsApp Business Cloud API integration — connect a real WhatsApp Business number through Meta and your agent replies natively, with full CRM memory per contact.
• Instagram & Messenger — one webhook, three Meta-owned channels. Configure once, reply everywhere.
• Public chat page & embed widget — every agent ships with a sharable link (great for QR codes, email signatures and link-in-bio) and a one-line widget snippet for any website.
• Knowledge base — upload PDFs, CSVs, plain text or Markdown. Your agent answers using your content first, with a smart fallback to the model's general knowledge.
• Custom voices — nine premium voices for voice replies, with a live preview before you commit.
• Per-contact CRM memory — your agent remembers customer names, emails, phone numbers and the conversation context, automatically.
• Intake forms with read-back — collect bookings, leads or order details with confirmation prompts.
• Pause AI for high-touch contacts — flip a switch to hand over a single conversation (or a whole list of VIPs) to a human teammate.
• Branded widget — customise colours, logo, header, welcome message and launcher position to match your brand.
• Usage analytics — 14-day sparkline of messages, unique contacts and rate-limit blocks so you can see what's working.
• Rich social previews — every share link auto-generates an Open-Graph card so it looks polished on LinkedIn, X, WhatsApp and Slack.

Who is using AgentReply right now? Real-world examples.

Curious what AgentReply actually looks like in production? Here are five concrete examples drawn from real customer setups. Names are anonymised, but the workflows and numbers are real.

Example 1: A 14-table family restaurant in Manchester

The owner used to lose 8-12 booking requests per week because nobody could answer WhatsApp between 11pm and 9am. With AgentReply, the agent takes the booking, confirms the date and party size in a polite read-back, and drops a clean row into the team's shared Google Sheet via the intake form. Last month: 87 bookings captured automatically, zero double-bookings, and the owner finally got a full night's sleep.

Example 2: A Shopify skincare brand running Meta Ads

Instagram DMs explode every time a paid ad goes live. AgentReply's agent fields the "is this cruelty-free?", "how long does shipping take?", "do you have a discount code?" questions instantly — using the brand's tone-of-voice prompt — and escalates anything weird to a human via the AI-pause toggle. Result: cart-abandonment recovery up 23%, support tickets down by half, and the founder stopped working Saturdays.

Example 3: A 3-person SaaS startup with a marketing site

They embedded the AgentReply widget on every landing page with a single <script> tag. The agent now answers feature questions ("does it integrate with Slack?"), routes pricing enquiries to a calendar link, and captures email addresses from interested visitors. They're seeing 4× the qualified leads compared to the static "request a demo" form they had before — without writing a single decision tree.

Example 4: A boutique real estate agency in Lisbon

Buyers and renters DM via Instagram and WhatsApp at all hours. The agent qualifies them — budget, bedrooms, neighbourhood, move-in date — using a structured intake form, then sends the captured data plus chat transcript to the agent on duty via email. Average qualification time dropped from "next morning" to under 90 seconds. Sales team now starts the day with hot leads instead of cold inboxes.

Example 5: A part-time freelance personal trainer

Doesn't have time to reply to "do you have space?" enquiries during client sessions. AgentReply's agent answers, shares the rate card, and books a free 15-minute intro call via a Calendly link in the welcome message. Two new paying clients per month, attributable directly to messages that came in while he was at the gym.

Whatever the niche, the workflow is the same: write your agent's persona, paste your knowledge base, pick a channel, share the link. Try it free for 14 days →

Why pick AgentReply over a generic chatbot builder?

Fair question. There are a lot of chatbot builders out there — so what makes AgentReply different? Here's the honest answer:

• Real conversations, not decision trees. Powered by Claude Sonnet 4.5 and OpenAI Whisper/TTS, your agent understands intent and replies naturally. No rigid flowcharts to maintain at 2am when a customer asks something you didn't anticipate.
• Channel-native, not iframe-only. Your agent replies on the actual WhatsApp number, Instagram inbox or Messenger thread your customers use — not just a website popup that nobody clicks.
• Truly customisable. Brand colour, logo, welcome message, launcher position, persona, voice, knowledge base — every detail is yours to set, no developer required.
• Honest pricing. $9.99/month, $70/year or $250 lifetime. No per-message fees, no surprise overages, no enterprise sales calls before you can try it.
• Privacy-first. No third-party retargeting, transparent sub-processor list, GDPR-aware data handling. Full disclosure in our privacy policy.

Frequently Asked Questions

How long does it actually take to build my AI agent?

Five minutes for the basics; about an hour if you want to upload a meaty knowledge base, customise the brand colours, and connect a real WhatsApp Business number through Meta. The longest part is usually deciding what voice to pick.

Do I really need a credit card to start?

No. Every new AgentReply account gets a free 14-day Pro trial. No card. No "free until you forget to cancel" trap. We just want you to actually use the product before we ask you to pay for it.

What if I want to cancel later?

Cancel from the billing page in two clicks. No contracts, no exit interviews, no "are you sure?" pop-ups designed to wear you down.

Can my AI agent reply in my customers' language?

Yes — over 30 languages out of the box. Your knowledge base, prompts and replies can all be in your local language. The model picks up nuance like polite forms, slang and regional spelling automatically.

Is my customer data safe?

Yes, and we don't ask you to take our word for it. See our privacy policy and GDPR commitments. All sub-processors (Anthropic, OpenAI, Stripe, MongoDB Atlas, HostGator) are listed by name.

Will my AI agent sound robotic?

Not unless you write a robotic persona prompt. Most owners spend ten minutes shaping the agent's voice — warm, professional, cheeky, whatever fits the brand — and the replies feel like a thoughtful teammate, not a 2007-era chatbot.

How much does AgentReply actually cost?

Three honest plans: Pro Monthly at $9.99/month, Pro Yearly at $70/year (saves 41%), or Lifetime for a one-time $250. No per-message fees. No tiered usage limits. No enterprise sales calls before you can see a price.

Does it work with Shopify, WordPress or Webflow?

Yes — you get a single <script> tag that drops into any HTML page. We've tested it on Shopify, WordPress, Webflow, Squarespace, Wix and hand-coded static sites. Takes about 30 seconds to install. If your platform lets you paste HTML, AgentReply works.

Can the AI agent qualify leads automatically?

Yes — and this is where most owners see the biggest ROI. Build a structured intake form inside your agent (budget, timeline, contact details, anything custom) and the agent will collect them naturally during the conversation, then save everything to a clean CRM record you can export to CSV or pipe to Zapier.

Is AgentReply GDPR-compliant?

Yes. We disclose every sub-processor by name. EU customer data stays within EU regions. Right-to-erasure requests honoured within 30 days. Full details on our GDPR page — no lawyer-speak, just plain English.

Can I pause the AI for VIP customers?

Yes. Flip a toggle and a specific contact gets handed off to a human teammate — your AI stops replying to them so you can step in personally. Switch it back on whenever you want. Useful for high-value clients, complaints, or anyone who explicitly asks for a human.
