FastTrackr AI
FastTrackr AI (fasttrackr.ai) is an AI executive assistant that runs on WhatsApp, built from separate modules including a Meeting Assistant and Document Intelligence tool. It suits people who want an assistant for scheduling and document handling rather than general daily tasks. Some modules have a free tier; others, like Advisor Transitions, use custom pricing scoped per client, so overall cost depends on which modules you need. Launched in 2024 and the most-voted product in this list (85 votes on launch day), it has the longest public track record of the alternatives here. One limitation: because pricing varies by module, it's harder to know upfront what you'll pay.
Yatter AI
Yatter AI (yatter.in) is a personal AI assistant that works on both WhatsApp and Telegram, giving it more reach than WhatsApp-only tools. It suits users who want assistant access across both messaging apps rather than being locked to one. It offers a free tier, with a paid Yatter Plus plan at $5/month (down from $8) that adds unlimited conversations and ChatGPT Plus models. Launched in 2023, it's the oldest product in this comparison. One limitation: the free tier's message limits aren't detailed on the site, so it's unclear how far it goes before you need to upgrade.
Yaya AI Whatsapp Assistant
Yaya AI (yayagent.com) turns WhatsApp into a personal AI assistant with a clearly tiered pricing structure: a free basic plan (100 messages/month), a Pro plan at $5/month, and an Ultimate plan at $14/month for unlimited messages and expanded features. It suits anyone who wants to try before paying and knows exactly what each tier includes. Launched in February 2026. One limitation: the free tier's 100-message cap is low for daily, ongoing use, so regular users will likely need to upgrade quickly.
Assistlyai
Assistlyai (assistlyai.co.in) turns WhatsApp into a productivity assistant, offering a 14-day free trial with no credit card required and a Pro Plan at roughly $2.39/month (₹199), which includes unlimited messages and meeting support. It suits budget-conscious users who want to test the product risk-free before committing. Launched in mid-2026, making it one of the newer options here. One limitation: it's a recent launch with limited track record, so long-term reliability isn't yet established.
AskGogo AI
AskGogo AI (askgogo.in) is a personal AI assistant on WhatsApp currently in private beta with a waitlist for access. It suits people comfortable signing up early and waiting for availability rather than using something today. No pricing is stated since it hasn't fully launched. Launched in May 2026 with modest early traction (3 votes on launch day). One clear limitation: it isn't openly available yet, so it can't be evaluated or used immediately.
WhatsAI
WhatsAI is a WhatsApp assistant for daily tasks that also offers remote access to a PC, a feature not found elsewhere in this list. It suits users who specifically want to control a computer remotely through WhatsApp messages. No pricing or free tier is stated. It's the oldest product here, launched in 2019. One limitation: with no pricing information and a much older launch date, it's unclear how actively it's maintained today.
Claw-Assistant
Claw-Assistant (claw-assistant.com) is an AI assistant for WhatsApp focused on productivity automation. It suits users looking for task and workflow automation rather than conversational help alone. No pricing or free tier is stated on the site. Launched in May 2026, it's one of the newest and least-established options (2 votes on launch day). One limitation: with no stated pricing and minimal traction so far, it's hard to judge value or stability.
How to choose
If you want a free tier to test before paying, Yaya AI, Assistlyai, Yatter AI, or FastTrackr AI are the clearer choices since all state one. If budget is the deciding factor and pricing is public, Assistlyai's ~$2.39/month is the lowest stated cost. If you want the most established product with a visible track record, FastTrackr AI or Yatter AI have been around longest. If none of these fit and you specifically need a senior-focused assistant, readywhen may still be worth checking directly, even though its pricing isn't published.
