Cairn gives AI agents a memory of repeated website workflows, so recurring tasks can be replayed with fewer page reads and tool calls.

Landing page captured for the 2026-09-05 issue.

Field notes

Cairn records the route an AI agent takes through a website, then reuses that route on subsequent runs instead of repeating page discovery. Its example downloads a September invoice in seven replayed steps, while the benchmark compares Cairn with Playwright MCP and Chrome DevTools MCP across 90 fresh Claude sessions. The page reports 30 correct answers out of 30 for each tool and says Cairn’s advantage appears after the initial learning run.
