Extend AI Toolkit | Extend
Build your AI agent with Extend
Use our open source AI toolkit to integrate the Extend API into your agentic workflows.
With an AI agent, all you have to do is ask.
A little prompt goes a long way.
Ask your agent for things like reports, status updates, or tell it to match your receipts or update expense categories.
Make it work for you, automatically.
Tell your agent to monitor and alert you of specific activity, give it special categorization rules, or ask it to send your regular reports.
