How to Auto-Reply on WhatsApp & Telegram for Free

Yes — in 2026 you can set up a fully automated WhatsApp auto reply for free, plus Telegram, with no credit card and no code. On RevoplyAI's free plan you create an account, train an AI agent on your own FAQs, connect both channels, and go live in under 15 minutes. The free tier covers roughly 100 messages per month, which is enough to prove the concept before you pay anything.

Can you really auto-reply for free?

You can, and there's no catch buried in the fine print. The free plan gives you a real AI agent — not a limited demo — that answers customer questions on WhatsApp and Telegram using only the information you provide. It handles roughly 100 messages per month at no cost and without a credit card on file. That's designed for a small business, a solo founder, or anyone who wants to test whether an AI agent actually answers their customers well before committing to a paid plan.

The important detail is how the WhatsApp connection works. RevoplyAI connects through the official WhatsApp Business API as a verified Meta Tech Provider, so your number stays ban-safe. This is not an unofficial automation script that risks your account — it is the same infrastructure large brands use, available on the free tier. Telegram connects through a standard bot, which is free by design.

What do you need before you start?

Almost nothing. The setup is deliberately lightweight, but a few things ready in advance will make the 15 minutes go smoothly:

• A phone number for WhatsApp that is not already active on the regular WhatsApp or WhatsApp Business app — the Business API needs a clean number.
• Your FAQs or a few documents — pricing, hours, policies, common questions. A PDF, a Word file, or even a page of text works.
• Telegram (optional at first) — you can add the Telegram bot in a couple of clicks whenever you're ready; it doesn't need a phone number.
• No developer and no credit card. Everything happens in the dashboard with no code.

If you're not sure what to gather for the knowledge base, our guide on what to put in your AI knowledge base walks through exactly which documents give the best answers.

How do you set it up step by step?

Here is the full process on the free plan, in order. Most people finish all five steps in well under 15 minutes:

1. Create a free account. Sign up with your email — no credit card required. You land directly in the dashboard and start on the free plan immediately.
2. Upload your FAQ and documents to the knowledge base. Drag in a PDF, Word file, or plain text, or paste a website link. The AI reads this material and will answer only from it, so it never invents facts about your business.
3. Connect WhatsApp and Telegram. Link your WhatsApp number through the official Business API and add your Telegram bot. Both channels share the same AI agent and the same knowledge base, so you set up your answers once.
4. Test replies in the sandbox. Before any customer sees it, use the built-in testing sandbox to ask the agent real questions and confirm the answers are accurate. Tweak your documents if an answer isn't quite right.
5. Go live. Flip the agent on. From that moment, incoming messages on WhatsApp and Telegram get instant, accurate replies — and anything the AI can't handle can be handed off to a human in the shared inbox.

That's the entire flow. If you want a walkthrough focused purely on speed, our 3-minute setup guide covers the fastest path to a working agent, and the Telegram bot for business article goes deeper on the Telegram side specifically.

What are the free plan's limits?

Being honest about the ceiling matters more than overselling it. The free plan is a genuine starting point, not a permanent solution for a busy business. Here is what it does and doesn't cover:

• Roughly 100 messages per month. Every AI reply counts toward that allowance. For a low-volume shop or an early test, it's plenty; for a store fielding dozens of chats a day, you'll reach it quickly.
• Same core AI quality. The free agent uses the same knowledge-base grounding and anti-hallucination behavior as the paid plans — you are testing the real product, not a watered-down version.
• WhatsApp, Telegram, and the website widget are all available, so you can genuinely evaluate omnichannel replies before paying.

The free tier exists to answer one question honestly: does the AI reply well enough to trust with your customers? Once the answer is yes, the message limit becomes the only real reason to move up.

When should you upgrade?

The signal to upgrade is simple: you keep running out of messages before the month ends. When 100 replies a month no longer covers your inbound volume, the Pro plan at $29/mo raises the allowance to roughly 2,000 messages — about twenty times the headroom. For most small and growing businesses, that's the tier where an AI agent stops being an experiment and starts being your always-on front line.

Upgrading is worth it when automation is clearly paying off — when the agent is handling a large share of routine questions and freeing your team from repetitive replies. RevoplyAI can automate up to 80% of inquiries and reduce support costs by around 60%, but you only feel that impact at real volume. If you need even more, the Business plan at $59/mo covers roughly 6,000 messages, and yearly billing saves 20% on any paid tier. The clean path is to start free, confirm the value, and pay only when the numbers justify it.

Frequently Asked Questions

Is it really free?

Yes. The free plan requires no credit card and costs nothing. You get a real AI agent that replies on WhatsApp and Telegram for roughly 100 messages per month, trained on your own documents. It's not a time-limited trial that expires after a week — it stays free as long as you stay within the message allowance.

What happens when I reach the free message limit?

When you hit the roughly 100-message monthly limit, automated AI replies pause until the allowance resets the next month or until you upgrade. Your account, your knowledge base, and your connected channels all stay intact — nothing is deleted. Most businesses that hit the limit consistently move to the $29/mo Pro plan for about 2,000 messages, which is enough headroom for steady daily volume.

Will my WhatsApp number get banned on the free plan?

No. RevoplyAI connects through the official WhatsApp Business API as a verified Meta Tech Provider, so your number is ban-safe on every plan, including the free one. This is the sanctioned way to automate WhatsApp — not an unofficial workaround — which is exactly why it's safe to run your live business number on it.

RevoplyAI lets you turn free WhatsApp and Telegram auto-replies into a real, always-on AI agent in under 15 minutes — start free, and upgrade only when your message volume says it's time.
