What problems does Cosine solve for engineering teams?

Cosine helps engineering teams move faster by handling repetitive tasks - from bug fixes and migrations to documentation - so developers can focus on high-impact work.

Cosine helps engineering teams move faster by tackling the work that slows them down - from bug fixes and backlog cleanup to code migrations and documentation. It acts as an autonomous teammate that handles the repetitive, non-differentiating tasks so developers can focus on building features that matter.

How Cosine helps in practice

Most engineering leaders face the same problems:

  • Persistent backlogs: Non-critical bugs, minor UI issues, or low-priority tickets often pile up and remain unresolved. Cosine can clear these backlogs by taking tickets directly from Jira, GitHub, or Slack and delivering tested pull requests. → See what tasks Cosine can complete end-to-end.

  • Slow cycle times: Developers spend valuable time reproducing bugs, writing boilerplate code, or updating dependencies. Cosine shortens these loops by automating common fixes and updates, accelerating time-to-merge. → Learn how Cosine’s agent loop works.

  • Context-switching overhead: Jumping between repos, docs, and tasks drains productivity. Cosine autonomously retrieves context, navigates codebases, and plans solutions without constant human prompting.

  • Technical debt and maintenance: Many teams struggle to allocate time for refactoring or documentation. Cosine includes features like AutoDoc, which generates or updates documentation, and handles refactors that improve long-term maintainability.

  • Skill bottlenecks: Legacy systems, niche frameworks, or under-documented services often require specialized knowledge. Cosine’s model is trained to handle unfamiliar codebases, and can even be fine-tuned on a company’s proprietary languages and standards.

Real-world outcomes

  • Teams using Cosine report 30–40% of backlogged issues resolved that otherwise wouldn’t get touched.

  • A financial institution used Cosine to accelerate a cloud migration project, cutting estimated timelines from a month to two weeks. → Read more about deployment options.

  • Cosine’s own team has merged 1,700+ PRs since June with the help of the agent, proving its ability to operate as the most productive “engineer” on the team.

Why it matters

Cosine doesn’t replace engineers — it multiplies their impact. By handling repetitive, time-consuming, and low-leverage tasks, Cosine frees teams to focus on innovation, feature delivery, and solving hard technical problems.
