OpenTag

An AI coworker in Slack that answers, does the work, and automates the repeats

Slack-native AI coworker

Mention OpenTag in a thread and the answer or completed work returns to that same channel, with no separate app to babysit.

40+ model routing

Each request is routed to the most suitable model from families such as GPT, Claude, Gemini, DeepSeek, Grok, Kimi, Qwen, Llama and Mistral, targeting large cost savings versus sending everything to a frontier model.

50+ tool integrations

Connect Slack, Google Workspace, Notion, Confluence, Linear, ClickUp, GitHub, HubSpot, Stripe, PostHog, Fireflies, Granola and dozens more so work moves from question to action.

Approval-gated actions

Consequential steps are presented for review, and you can approve, adjust or decline before anything in a connected system changes.

Strengths & Pros

+Works inside Slack rather than forcing a new interface
+Model-agnostic routing can cut cost per task versus a single frontier model
+Permission-scoped agents and approval gates keep sensitive actions in human hands
+Broad integration catalogue covering engineering, sales, finance and analytics tools
