Solution · Knowledge work

Put your own codebase, conventions and runbooks behind your developers' AI tools.

We connect AI assistance to your repositories, architecture docs and ticket history, add task-specific helpers for tests, migrations and reviews, and keep every change inside the pull request, CI and approval process you already trust.

Who uses it

The workflow

Engineering teams maintaining large or aging codebases, and the senior engineers who spend much of their week answering questions and reviewing changes.

Today
  • New engineers need weeks of pairing before they can change core services safely.
  • Test coverage is thin in the code that changes most, so reviews rely on memory.
  • Repetitive changes such as dependency upgrades and API migrations take weeks of manual work.
  • Generic AI coding tools do not know internal libraries, conventions or security rules.
  1. Index code and context

    System

    Repositories, architecture decision records, runbooks and resolved tickets are indexed with the same access rules as the source systems.

  2. Pick up a task

    Person

    A developer takes a ticket and asks where the relevant code lives, how a service behaves, or how similar changes were made before.

  3. Propose changes and tests

    AI

    The assistant drafts code changes, tests and a description following team conventions, citing the files and examples it used.

  4. Run automated checks

    System

    The pull request runs through CI, static analysis, secret scanning and the test suite like any other change.

  5. Review and merge

    Person

    A developer reviews the change, edits it as needed and a code owner approves it before merge.

What to measure

Where people stay in control

No AI-generated change merges without a person reviewing it and the normal code-owner approval. The assistant has read access to code and write access only to branches and draft pull requests; it cannot push to protected branches, change CI configuration or access production secrets.

  • Time for a new engineer to ship a first production change
  • Review cycle time on pull requests
  • Test coverage in the most frequently changed modules
  • Defects found after merge in AI-assisted changes compared with others

Data and integrations

  • Read access to repositories and the code hosting platform API
  • Architecture docs, runbooks and ticket history
  • CI pipeline and static analysis configuration
  • Team coding standards and security rules

Realistic boundaries

  • Output quality depends on test coverage; where tests are thin, reviewers carry more of the checking.
  • Source code may only be sent to model endpoints your security team approves, which can limit model choice.
  • Architecture and design decisions stay with engineers; the assistant proposes, it does not decide.

Questions buyers ask

Off-the-shelf tools are a reasonable starting point. We add what they lack — your internal context, task-specific workflows such as migrations or test generation, and controls on data handling and permissions — and we can build on top of the tools your team already uses.

Only if you choose that. We can run on models deployed in your own cloud account or use approved providers with no-retention terms. See private AI deployment.
