Tanka

Tanka is an AI-native operating base for teams that want to preserve institutional knowledge, automate workflows, and prevent context loss when employees leave. Built by the Tanka Team and headquartered in Redwood City, CA, the platform positions itself as a Slack alternative where every chat, decision, and file becomes permanent, searchable organizational memory. Tanka also offers a companion product called Relay, which creates a "digital twin" of departing employees so their expertise stays accessible after they leave.

What It Is

Tanka is a team communication and knowledge management platform with native AI built throughout — not bolted on as an add-on. Unlike conventional messaging tools, Tanka's core design centers on what it calls "EverMind," a memory layer that continuously extracts and indexes knowledge from chats, files, and connected third-party apps. The result is a workspace where new hires can ask questions and get answers grounded in the team's actual history, and where SOPs can be generated directly from real decisions made inside the platform.

Core Product: The AI-Native Workspace

The main Tanka workspace (tanka.ai/slack) is marketed as a direct alternative to Slack, Discord, and Lark/Feishu, with several differentiating capabilities:

• Unlimited AI Memory — Tanka claims to offer unlimited memory preservation, compared to what it describes as limited or deletion-prone memory in Slack and fragmented memory in Discord.
• Chat that remembers — The AI assistant searches the team's entire communication history to answer questions grounded in what the team actually knows.
• Flow — An automation layer that turns accumulated decisions and context into drafts, research outputs, SOPs, memos, and follow-ups without manual overhead.
• SOP Builder — Generates standard operating procedures from real decisions made in Tanka, designed to accelerate onboarding.
• 100+ app integrations — Connects messaging, email, CRM, data, and productivity tools into one unified knowledge base.
• One-click data export — Tanka emphasizes data portability as a differentiator, contrasting with what it describes as Slack's "locked in" approach.

Relay: The Employee Knowledge Preservation Tool

Relay (relay.tanka.ai) is a separate but related product from Tanka that addresses the "two weeks notice panic" — the loss of institutional knowledge when key employees depart. Relay works in three steps:

1. Connect — Link the departing employee's work apps (email, chat, calendar, docs) with one click.
2. Capture — Relay's EverMemOS engine analyzes years of communication to reconstruct the employee's knowledge graph, decision patterns, and expertise.
3. Consult — A Relay Agent is added to the team's chat channel (Tanka, Slack, or Teams), where colleagues and new hires can ask it questions as if talking to the real person.

Relay is currently in waitlist access mode. It is designed for founders, product leaders, and sales and marketing teams where, as the product page states, "knowledge equals competitive advantage."

Platform and Integration Model

Tanka operates as a web and mobile application with apps available on iOS (App Store) and Android (Google Play). The platform integrates with over 100 third-party tools including messaging, email, CRM, and productivity apps. Relay specifically connects to Slack, Email, and Zoom to learn how decisions were made. Both products live in team chat environments, with Relay also supporting Microsoft Teams as a deployment channel.

Update: Blog Activity and Product Direction (Early 2026)

Tanka's blog shows active publishing into early 2026, with posts covering topics such as AI memory architecture ("Memory is Not Storage; It is Intelligent Data," January 2026), organizational evolution through AI roles (February 2026), and data privacy in AI-native companies (December 2025). These posts signal an ongoing product philosophy around "EverMind" as a first-person neural circuit rather than a passive document store, and a broader vision of Tanka as an "Operating Base for AI-Native Companies" that scales intelligence rather than headcount.
