Anthropic's AI assistant for real work, from chat to agents
Access to a range of Claude models tuned for different tradeoffs between speed, cost, and reasoning depth, including vision and long-context work.
Claude can produce working code, documents, slides, and spreadsheets in an editable side panel or output file rather than only plain chat replies.
Hand off multi-step tasks; Claude can search the web, read files, run code, and work across schedules or connectors depending on your plan.
Dedicated coding surfaces plus a developer platform and console for building applications on Claude models with API access.

The AI-native helpdesk that turns Slack and Teams chats into resolved tickets
Detect and create tickets from channel threads or private bot DMs, so requests become trackable work without asking anyone to leave their chat app.
AI combines the conversation, requester history, connected knowledge and live systems data to answer questions and take actions rather than merely routing them.
Resolved conversations are turned into new or updated documentation, so the knowledge base stays current and future questions are deflected automatically.
Trigger approvals, updates and multi-step workflows across Jira, Linear, HubSpot, Salesforce, Workday, Okta, Stripe and other connected tools, plus Zapier, Make and webhooks.
