Devin is an autonomous AI software engineer that can write, run and test code. Devin can handle most tasks, excluding extremely difficult tasks. As a rule of thumb, if you can do it in three hours, Devin can most likely do it. Ask Devin to tackle Linear/Jira tickets, implement entirely new features, repro and fix bugs, build internal tools, and more!

What are Devin’s strengths?

Here are the types of tasks where Devin excels:
  1. Tackling many tasks in parallel, before they end up in your backlog
    • Linear/Jira tickets
    • Entire features from scratch
    • Bug reports
    • App testing
  2. Code migrations, refactors, and modernization
    • Language migrations (e.g. JavaScript to TypeScript)
    • Framework upgrades (e.g. Angular 16 -> 18)
    • Monorepo to submodule conversions
    • Removing unused feature flags
    • Extracting common code into libraries
  3. Common, repetitive engineering tasks
    • PR Review
    • Codebase Q&A
    • Reproducing & fixing bugs
    • Writing unit tests
    • Maintaining documentation
  4. Customer engineering support
    • Building new integrations and working with unfamiliar APIs
    • Creating customized demos
    • Prototyping solutions
    • Building internal tools
To get the best results from Devin:
  • Write clear prompts with explicit completion criteria — the clearer the task, the higher the success rate, especially for complex work.
  • Make tasks easy to verify — e.g. checking that CI passes or testing an automatic deployment.
  • For harder tasks, break them into well-scoped steps and provide relevant context or examples.
  • Follow our best practices and pre-task checklist.
The most successful workflows include:
  • Tagging Devin on a Slack or Teams thread about a bug you’re discussing with coworkers
  • Delegating a more complex task via the web application and taking over in Devin’s IDE once it gives you a good first draft.
  • Carving out tasks from your todo list at the start of your day and returning to draft PRs waiting for review.
Devin is most effective when it’s part of your team and your existing workflow.
