Devin is an autonomous AI software engineer that can write, run and test code, helping software engineers work on personal tasks or their team projects.

Devin can review PRs, support code migrations, respond to on call issues, build web applications, and even perform personal assistant tasks like ordering your lunch on DoorDash so you can stay locked in on your codebase.

​
What are Devin’s strengths?

Here are the types of tasks where Devin excels:

  1. Code Migrations & Modernization

    • Language migrations (e.g. JavaScript to TypeScript)
    • Framework upgrades (e.g. Angular 16 -> 18)
    • Cloud infrastructure modernization (e.g. AWS -> Azure)
    • ETL code migrations (e.g. Airflow -> DBT)

  2. Large-Scale Refactors

    • Monorepo to submodule conversions
    • Code structure reorganization
    • Removing unused feature flags
    • Extracting common code into libraries

  3. Engineering Excellence

    • Improving test coverage
    • Addressing lint/static analysis errors
    • Documenting existing code
    • Investigating and fixing CI failures
    • Addressing small backlog tasks

  4. Customer Engineering Support

    • Building customer-specific integrations
    • Creating customized demos
    • Prototyping solutions

The most successful Devin tasks typically have:

  • Clear validation criteria (e.g. tests passing, builds succeeding)
  • Junior engineer level complexity
  • Repetitive patterns that require small variations
  • Examples of “what good looks like”

Tag Devin on a Slack thread about a bug you’re discussing with coworkers, delegate a task in your IDE to save you from context switching, or hand Devin your todo list at the start of your day and return to draft PRs waiting for review. Devin is most effective when it’s part of your team and your existing workflow.

​
Getting Access

To access Devin, you can sign up for a Teams account at app.devin.ai.

If your company is already working with Cognition, you can request permissions with your Administrator or Cognition directly and access Devin via the web application app.devin.ai.

For those on our individual plan waitlist, we release new spots weekly, inviting users to join our Technical Preview and participate in our Discord and Slack communities.

General Product Features

​
The Devin Interface

Devin is designed to be a conversational user interface, and allows you to follow Devin’s development and planning process in the Workspace section.

In Devin’s Workspace, you’ll find:

Shell

a text-based interface where Devin can input commands that interact directly with a computer’s operating system.

Browser

Watch Devin browse through documentation, test web applications it builds, download/upload information, and jump in to help Devin navigate through browsing tasks.

Editor

this is where Devin will write code. You can supervise, review and edit (see our VSCode Guide) the code Devin is writing.

Planner

this section provides you a running “to do” list that Devin laid out to complete the task. This gives you visibility into how Devin plans and thinks through solving a problem.

​
Limitations

Devin is an early product and has lots to learn. The Cognition team is working hard to improve Devin’s breadth of capabilities.

As you use Devin, keep in mind tasks that will be harder for it to execute successfully:

  • Large-scale challenges: Devin generally performs better on smaller, clearly scoped tasks. For more complex edits, we recommend breaking up the project into smaller, isolated tasks that you can run in separate sessions that build on each other. If you need to frequently run multiple sessions in parallel, you can use the External API to create sessions and retrieve structured results programmatically.
  • Consistency and reliability: Devin will sometimes get off-track. Sometimes you’ll be able to nudge Devin back on track, other times you may want to restart the session.
  • UI-related aesthetics: Devin can build functional frontends, but will need your help with aesthetics. Devin doesn’t have great eyesight.
  • Mobile development: Devin can help with mobile applications, but doesn’t have a phone to test with.
  • Security: This is our top priority at Cognition, but we ask all users to exercise caution when sharing credentials with Devin or granting access to specific platforms. Any time you are sharing credentials with Devin, make sure you use the Secrets Manager or via the secure credential-sharing channel provided by Devin in the chat.

​
Feedback

We’re learning and our customers’ input is crucial! If you are part of the Technical Preview, please reach out via our Slack Community. For all other customers and partners you can share your feedback to support@cognition.ai or directly in the web app.

We log all feedback provided by customers and use it to make quick improvements to Devin and inform our product priorities and roadmap.
