AiSensy is a free-forever WhatsApp platform with AI chatbot builder and e-commerce integrations. WhatSender is a bulk-sending workspace for rapid campaigns from your existing number.
The short answer
Pick WhatSender if you want to send campaigns today without waiting for Meta approval, and need a flat ₹300/month with no per-message cost. Pick AiSensy if you want zero platform fees, an AI chatbot, and don’t mind paying Meta’s per-message rates (₹1.09/marketing message) and 18% GST on everything.

AiSensy’s free-forever model is genuine: no platform fee, no API procurement charge, no hidden costs on day one. For SMBs with tight budgets, this is the lowest barrier to entry on the market.
But the bill is paid per message. At scale, a campaign to 10,000 prospects costs 10,000 × ₹1.09 = ₹10,900 in message fees alone. Add the Basic platform plan (₹1,500) and 18% GST on both (₹1,755), and you’re paying ₹13,655 for one campaign. WhatSender’s ₹300/month flat covers the same campaign and a thousand more.
The honest advantage: if you’re sending 500 messages a month, AiSensy is cheaper. If you’re sending 10,000 a month, WhatSender is cheaper by thousands. GST—which AiSensy passes through but WhatSender doesn’t—widens the gap.
If you need an AI chatbot that learns from conversations and qualifies leads without human intervention, AiSensy ships that as product. Knowledge base Q&A, drag-and-drop flows, and Shopify/WooCommerce hooks come built-in. WhatSender’s REST API means building the same features yourself.
AiSensy also removes a barrier for small businesses: no Meta approval required if you use their virtual number (₹2,000/year). For founders testing ideas, the friction is lower.
AiSensy still requires Meta Business API verification, which takes 3–5 days and involves business registration documents. WhatSender connects by QR code in minutes and sends immediately. If you need to run a campaign this week, WhatSender wins.
If you have six months to build a chatbot-driven customer success system and want the lowest platform cost, AiSensy is a serious contender — provided you’re comfortable with Meta per-message rates and GST stacking up.
WhatSender drives a regular WhatsApp number through an automation layer rather than Meta’s official API. That is why there is no approval queue and no per-message fee — and also why there is no green tick, and why a number that blasts cold contacts can be restricted by WhatsApp. Warm-up limits and daily caps exist to manage that risk, not to remove it.
AiSensy’s free tier is platform-free (₹0), but you pay Meta’s per-message charges separately. At ₹1.09/message for marketing (effective January 2026) plus 18% GST, a 1,000-message campaign costs ₹1,285. WhatSender is ₹300/month flat for unlimited campaigns that month.
Yes. AiSensy requires WhatsApp Business API verification but charges zero rupees to procure the API. Approval takes 3–5 days if your business documents are in order. WhatSender connects by QR scan in minutes to your existing number.
At 200 messages/month, you pay ₹218 in Meta charges plus 18% GST (₹39) = ₹257 total on the free plan. WhatSender’s ₹300/month is overkill. For 5,000/month, AiSensy costs ₹5,450 + GST (₹981) = ₹6,431 — more than ₹300/month.
Not directly with the free plan; you need the Business API. AiSensy offers a workaround: rent an Indian virtual number for ₹2,000/year (plus GST), which skips some API requirements. WhatSender connects to the personal number you already own and use daily.
The free plan sends 50 messages a day with no card and no approval queue. Paid plans start at ₹300/month.
