Master Devin (Cognition) with our step-by-step tutorial, detailed feature walkthrough, and expert tips.
Explore the key features that make Devin (Cognition) powerful for browser agents workflows.
Each Devin session spins up a full sandbox with a code editor, terminal, and browser, letting the agent install dependencies, run commands, browse docs, and execute code the same way a human developer would. This is what enables true end-to-end task completion rather than just code suggestions.
Devin maintains state and progress across long-running engagements that can span days or weeks, remembering architectural decisions, prior work, and project goals. This makes it viable for migrations and refactors that don't fit in a single session, including the COBOL modernization and Nubank-scale migration Cognition has publicized.
Announced April 2026, Devin for Terminal lets developers start a task in their local terminal and seamlessly hand it off to a cloud agent that continues working asynchronously. This bridges the gap between local-first development workflows and long-running cloud automation.
Introduced in April 2026, SWE-Check is Cognition's bug detection system that they report delivers 10x faster bug detection. It is designed to catch regressions and defects in agent-generated code as part of Devin's review and verification loop.
Following Cognition's acquisition of Windsurf, Devin is now integrated directly into the Windsurf IDE, combining inline AI editing with delegated agent execution. Users can edit interactively in Windsurf and offload longer tasks to Devin without leaving the editor.
Now that you know how to use Devin (Cognition), it's time to put this knowledge into practice.
