Tanka
AI team messenger with memory
Persistent AI memory that follows your team across every chat app
Reviewed by The Desk · Last verified July 2026
“Tanka's whole bet is memory: instead of yet another chat app, it's a layer that remembers every conversation, document and decision across your team's tools and uses that context to draft smart replies and to-dos. When the memory is accurate it's genuinely useful for context-heavy startup teams, but you're trusting a young company with broad access to your communications, and it pays off most only if you actually route messaging through it.”
Skip it ifSkip if your team is standardized on Slack or Microsoft Teams and won't funnel messaging through a new hub, or if connecting all of your communications to an early-stage startup raises data-privacy concerns.
What it is
Tanka is an AI business messenger built around long-term memory. Rather than positioning purely as a standalone chat tool, it layers onto the channels teams already use — WhatsApp, Slack, Telegram, Gmail and 95+ apps — indexing past conversations, documents and decisions so it can generate context-aware "Smart Reply" drafts, pull out to-dos, and surface insights across those channels.
The differentiator is its persistent memory layer (branded EverMem / EverMemOS), which the company says retains context across a team's connected tools and sharpens replies over time. Tanka is free for teams under 50 members with full integrations and the memory layer included; paid Plus ($29/mo) and Pro ($199/mo) tiers add credit allowances and advanced analytics, with custom enterprise pricing above that. It runs on iOS, Android, Mac, Windows and the web.
It targets startups and SMB teams drowning in cross-channel messages, and markets itself as an "AI co-founder." It is still early — founded by ex-Meta and ex-TikTok operator Kisson Lin with a public launch in 2025 — and competes with Slack AI, Microsoft Copilot and other assistants. The payoff depends heavily on how accurate the memory is and on how much of your communication you are willing to route through a young platform.

Pros & cons
The good
- Genuinely differentiated persistent long-term memory that carries context across WhatsApp, Slack, Gmail and more
- Generous free tier for teams under 50, plus wide integration coverage (95+ apps)
- Smart replies and auto-generated to-dos save real time on repetitive, cross-channel communication
The catch
- Real value requires adopting Tanka as a hub or granting broad access to your existing accounts — a big ask for teams already on Slack/Teams
- Long-term memory across all communications raises data-privacy and trust questions for a young startup
- Credit-based paid tiers can throttle heavy use, and Microsoft Teams integration was still missing as of early 2026
