ReplyKit vs AiSensy: an inbound AI agent on your existing number, or a broadcast and campaign platform on the official API
AiSensy is one of the most popular WhatsApp platforms in India and increasingly in Southeast Asia, built around campaigns, broadcasts and the official Business API. ReplyKit is built around answering the customers who message you, on the number you already have. They overlap on chat, and they are different products. Here is the comparison.
Quick answer
Choose AiSensy if you need to send marketing broadcasts and campaigns to large opted-in lists on the official WhatsApp API and can budget for Meta's per-message fees; its plans start with a free tier, then about $45 and $99 a month (India pricing is lower), plus Meta fees. Choose ReplyKit if you want an AI agent that answers enquiries from your own website and price list, books appointments and hands over to people, on your existing number on the official platform, with a website assistant included, from $29 a month. ReplyKit is $29, $49 or $99 a month with AI replies included (1,000, 5,000 or 20,000 a month), connected through Meta's official WhatsApp Business Platform with no pairing risk, a website assistant, booking, a CRM and inbox, and a 7-day free trial with no card. Meta's per-message fees apply only to reminder and follow-up templates sent outside the 24-hour window.

Where AiSensy wins
- Campaigns. Sending promotional and utility broadcasts to thousands of opted-in contacts is what it is built for. ReplyKit does not send campaigns at all.
- Sanctioned route. The official API means no restriction risk from automation, and the verified badge route.
- Team seats and attributes. Basic includes several agent seats; Pro adds campaign scheduling and access control.
- India-first pricing and support if that is your market.
AiSensy's pricing is on its pricing page. Meta's per-message fees are explained in API pricing explained.
Where ReplyKit wins
- The AI is the product. Paste your website, upload a price list, write plain instructions, and the agent answers in the customer's language, says when it is not sure, and hands over. No flow builder.
- Meta fees only on templates, no approval. Connect your number through Meta's sign-in and go; the bill is the plan.
- Website assistant included with its own knowledge and instructions.
- Booking into your slots with reminders and reschedules in the chat.
- Small business price with AI included from $29.
Where the connection matters: ReplyKit runs on Meta's official WhatsApp Business Platform, so there is no linked-device pairing and no restriction risk from automation. Meta's per-message fees apply only to reminder and follow-up templates sent outside the 24-hour window; replies to customers who message you carry no Meta fee inside it. The trade-offs are explained in why ReplyKit runs on the official platform.
What a month costs
AiSensy: the plan fee plus Meta's per-message charges for every business-initiated message, which for campaigns is the main cost; replies within the service window have been free and Meta has announced changes to that from late 2026, so check the current schedule. ReplyKit: the plan fee, nothing else.
ReplyKit plans: Starter $29 (1 number, 1 agent, 1 website assistant, 1,000 replies), Growth $49 (3 numbers, 5 agents, 5 website assistants, 5,000 replies, follow-up nudges), Pro $99 (15 numbers, unlimited agents, 20,000 replies). Extra replies are $10 per 1,000. AI is included, and Meta's message fees apply only to reminder and follow-up templates. Details in what it costs.
Who should choose which
- You run promotions to a list: AiSensy or another API platform.
- You are drowning in inbound enquiries and bookings: ReplyKit.
- Both: some businesses run campaigns on an API platform and answer on a ReplyKit number; keep them on separate numbers.
- You want zero platform risk: the API route, and accept the fees and setup.
