A WhatsApp AI assistant for personal use
Updated 12 October 2026
Most "WhatsApp AI" products are chatbots for businesses that reply to customers. RelayMCP is different: it's an assistant for your own WhatsApp, used from the AI tool you already like (Claude, ChatGPT, Cursor or your own agent), to keep on top of your conversations.
Everyday uses
- Never forget a promise: "Remind me tomorrow at 10 to call Rahul back."
- Chase what's pending: "If the supplier hasn't confirmed by Friday, draft a nudge."
- Catch up fast: summarise busy family, society or work groups: decisions, questions for you, things waiting on your reply.
- Find it again: "What address did Neha send?"
- Voice notes: transcribed in Hindi and English.
- Replies: drafted in context; you approve before anything is sent.
Who it's for, and who it isn't
It's for individuals and busy professionals who live in WhatsApp. It is not for marketing, broadcasts or bulk messaging; the limits below make that impossible by design. If you need to message customers at scale, use the official WhatsApp Business Platform instead.
Privacy safeguards
- Block any chat or group. Its messages are dropped the moment they arrive: never stored, never shown to your AI, media never downloaded. Blocking also wipes anything already stored for that chat.
- Only you can unblock. Unblocking needs a code shown only on your own RelayMCP dashboard; your AI never sees it.
- Short memory, not an archive. Messages are deleted automatically after 72 hours (adjustable), and old chat history isn't downloaded when you link.
- Locked with your key (pilot feature). Stored messages and media are encrypted with a key only you hold, protected by a passphrase we never store. This protects stored data; it isn't WhatsApp's end-to-end encryption, and it doesn't cover metadata (who you message and when) or messages while the connected service is handling them. Details.
- Encrypted at rest, stored in India (AWS Mumbai). Logs never contain message text.
- Delete anytime. Unlink the device and all your data is wiped.
Anti-spam limits (always on)
RelayMCP is a reminder and follow-up tool, not a broadcast tool. On every plan: you approve sends; approved messages go out after a random 30–120 second delay; one person per message; no groups or broadcast lists; only your contacts or existing chats; no sends 9 PM–9 AM recipient-local; about 30 unique recipients a day; the same text to at most 3 people. Misuse gets the account paused or banned.
Good to know
- RelayMCP is in a private pilot. It's free for pilot users; join the waitlist to get access.
- It links to your personal WhatsApp as a companion device through WhatsApp's Linked devices feature. It is an independent product, not affiliated with or endorsed by WhatsApp or Meta, and WhatsApp's terms on unofficial clients apply to your account.
- Content your AI tool reads through RelayMCP is also processed by that tool's provider under its own terms.
