An AI coworker in Slack that answers, does the work, and automates the repeats
Mention OpenTag in a thread and the answer or completed work returns to that same channel, with no separate app to babysit.
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.
Connect Slack, Google Workspace, Notion, Confluence, Linear, ClickUp, GitHub, HubSpot, Stripe, PostHog, Fireflies, Granola and dozens more so work moves from question to action.
Consequential steps are presented for review, and you can approve, adjust or decline before anything in a connected system changes.
No-code AI agents grounded in your company's knowledge
Configure AI agents through a visual interface, connect company data for context-aware actions, and swap between models without rewriting your setup.
Ground agents in internal docs, wikis and tools so they can research and act on company knowledge alongside the public web.
Build multi-step automations in a node-based editor and schedule agents to run recurring work even when you are offline, delivering results to your inbox.
A browser extension brings the same agent experience to thousands of apps and websites, avoiding constant context switching.
