Not a code-completion tool. A team-level developer fellow.

Developer Fellow

A custom-built AI developer that lives in your team's Slack. Reviews pull requests, handles dependency upgrades, drafts internal docs, and summarizes on-call activity. Trained on your codebase, your conventions, and your team's review style.

What a Developer fellow does

The team-level dev work that slows everyone down, handled.

R

Reviews pull requests.

Catches the easy stuff (style, obvious bugs, missing tests) before a human reviewer wades in.

U

Handles dependency upgrades.

Opens upgrade PRs, runs the test suite, and flags breaking changes for human attention.

D

Drafts internal docs.

READMEs, ADRs, runbooks, onboarding docs — drafts on request, in your team's voice.

S

Summarizes on-call.

Reads the incident channel and drafts the postmortem; pulls deploy timeline and error log highlights.

T

Builds small internal tooling.

Scripts, dashboards, internal API helpers. Scoped, reviewed, shipped via PR.

I

Triages issues.

Reads incoming GitHub or Linear issues, tags by component, pings the right person, asks for repro steps when missing.

Tools your Developer fellow connects to

Deep, role-specific integrations. Not 3,000 shallow ones.

How a Developer fellow shows up in your channel

Your first 30 days with a Developer fellow

Week 1

Setup

  • Scope the role with you (repos, conventions, review style, runbooks)
  • Custom-train Kai on your codebase and prior PRs
  • Add Kai to your Slack and connect GitHub/Linear in read mode first

Week 2

Shadow

  • Kai reads PRs and issues in read-only
  • You give it small jobs: comment on this PR, draft this README
  • Every output reviewed before publish

Week 3

Delegate

  • PR pre-review runs automatically; human reviewer follows
  • Weekly dependency upgrade PRs ship from Kai
  • On-call summaries draft each morning

Week 4

Measure

  • Review PRs touched, upgrades shipped, time saved on on-call writeups
  • Decide what to expand into Kai's scope
  • Onboard another role if ready

Why this is different from a code-completion tool

GitHub Copilot and Cursor help individual engineers type faster. A Developer fellow helps the team ship — by pre-reviewing PRs, keeping dependencies current, writing the postmortem, and handling the maintenance work that nobody wants to own.

Most teams run both. Copilot in the editor. Kai in Slack. Different layers.

Pricing

Each Developer fellow is on a custom annual plan based on the scope of your codebase and team size. Predictable annual price. No per-PR or per-line meters.

Frequently asked questions

No. Kai handles the high-volume, lower-judgment work — pre-PR review, dep upgrades, doc drafts, on-call summaries. Your engineers stay on architecture, hard bugs, customer-facing decisions, and judgment calls.

Those are inline code-completion tools that help one engineer type faster. Kai is a team-level fellow — works in Slack, reviews PRs, manages upgrades, summarizes on-call. Different layer of the stack. Most teams run both.

No. Kai opens PRs and pre-reviews; humans merge.

We scope Kai's repo and tool access during setup. We are pilot-stage and our compliance posture is on the roadmap. If you have hard security requirements (SOC 2 from your AI vendors, on-prem deployment), we will tell you what we can meet today.
