Devin
Autonomous AI software engineer from Cognition that plans, writes, tests and reviews code and opens pull requests.
Devin is an autonomous AI software engineer made by Cognition. Devin takes a task such as a feature, bug fix or dependency upgrade, works on it in the cloud or on a developer's machine, tests the result in its own browser and opens a pull request. Devin can also be tagged in Slack or Teams.
Best for Engineering teams that want to hand off well-defined coding work, such as fixes, upgrades, tests and reviews, to an agent that returns a tested pull request.

What is Devin?
Devin is an AI coding agent developed by Cognition and presented as an autonomous software engineer for engineering teams. A user describes a task in plain language, and Devin explores the relevant repositories, writes the change and tests it end to end on virtual machines that it starts for itself, which can run Windows, macOS or Linux. It records its browser testing and delivers the work as a pull request. Large jobs can be divided among parallel cloud agents that carry on after the user's laptop is shut. Around the core agent sit related products: a Wiki that maps a codebase and keeps its diagrams current, Devin Review for catching bugs and vulnerabilities in pull requests, and automations that respond to alerts, failed CI runs or a schedule. Devin can route work across models from several providers as well as Cognition's own SWE-2 model.
Key Features
Self-Run Testing
Launches its own virtual machine and browser, clicks through what it built and attaches a recording of the test.
Parallel Cloud Agents
Breaks a big task into parts, assigns them to several agents in the cloud, manages them and reports back.
Model Mixing
Combines models from different providers within one job, pairing a lead model with a cheaper sidekick.
Chat Tagging
Responds when mentioned in Slack or Microsoft Teams, reads the thread and starts on the request.
Automations
Runs scheduled or trigger-based workflows, for example fixing CI when it fails or triaging new issues.
Review and Wiki
Checks pull requests for bugs and security flaws, and maintains up-to-date maps and diagrams of the codebase.

Things to know
- Five plan tiers
- Devin is offered in Free, Pro, Max, Teams and Enterprise tiers; current prices are on the official pricing page.
- Usage is quota-based
- Each paid plan has an allowance that resets on a daily and weekly cycle, and message cost varies with the model, task size and reasoning needed.

- Cognition states that every session runs in its own virtual machine and that zero data retention is enforced with model providers.
- Enterprise deployment
- Enterprise customers can get SAML or OIDC single sign-on, audit logs and deployment in their own virtual private cloud.
