Kanvo and the apps you already use

You do not have to leave WhatsApp, Telegram or Slack to use Kanvo. It brings them into one inbox, screens out the spam on all of them, and adds what makes it an agentic messenger: an agent and a signed record none of them have.

Where Kanvo is different

Each of the apps below is excellent at something. None of them was built to sit across the others.

One inbox, every app

Your own WhatsApp, Signal, Instagram, Messenger, Discord, Slack, Google Messages, LinkedIn and X, and business accounts on Telegram, Teams, Google Chat and SMS, beside Kanvo's own conversations.

Spam stopped before it reaches you

Every incoming message is scored as it arrives, on every connected app. Scams go to Spam, strangers can wait in Requests, and none of it buzzes your phone.

An agent that can act

Ask what you missed across every app, draft replies in your voice, and let it send under limits you set — with a human approving anything risky.

Proof of Send

Every message that leaves Kanvo is signed: who sent it, a person or an agent, and on whose authority. Anyone can check it without an account. We found no other messenger that does this.

Private when it matters

A private conversation is end-to-end encrypted with MLS, the IETF standard, and you choose one when you start it. Ordinary conversations are not — that is what lets search, summaries and the agent work in them.

Open to your own agents

A REST API and an MCP server let your own software and AI agents read and send, each with a key scoped to what it needs. WhatsApp bans general AI bots from its Business API; iMessage and Signal have no API at all.

Side by side

A tick means the product does it, a dash means it does part of it — the note says which part — and a cross means it does not.

Spam, handled — even from Telegram

Every app on this page filters its own spam, some of it well. None of them can filter the others. Kanvo screens everything that reaches you through it, on every connected app, before it is allowed to make a sound.

Message requests

A first message from someone you share nothing with waits in Requests — on Kanvo by default, and on WhatsApp, Telegram, SMS, Instagram and Messenger when you switch on screening. Reply or tap Accept and it moves to your Inbox.

A score on every message

Wallet-drainer phrases, “guaranteed returns”, fake job offers, group-invite links, shortened links, floods and copy-pasted broadcasts each add to a score. Past your threshold — Standard or Strict — it goes to Spam, and the app tells you why.

Reports that protect everyone

Report a sender and they are blocked for you. When two people report the same account, it goes straight to Spam for every Kanvo user it writes to next. Nobody sees who reported whom.

Block anyone, on any app

Block a Telegram account, a WhatsApp number or a Kanvo user from the same menu. Their messages are still recorded — the record matters — but they arrive read, in Spam, and silent.

Nobody drops you in a group

Choose who can add you to groups and channels: anyone, people you know, or nobody. Someone you blocked never can, whatever you choose.

Your word is final

Not spam means not spam: the filter stops second-guessing that conversation. Spam is kept, never deleted, so a real message the filter caught is one tap from your Inbox.

Head to head

What each one is good at, where it stops, and what changes with Kanvo — including the ones you may not have heard of.
