Getting started

Install CoopAI and run your first chat in five minutes.

Last updated: 2026-08-21

This guide gets you from signup to your first useful chat in CoopAI.

What you'll need

  • VS Code 1.85 or later
  • A CoopAI account (free signup or invited by your org admin)
  • A local workspace folder open in VS Code

Step 1 — Create an account

Browsercoop-ai.dev/signup/free

Enter your work email and create a password, or continue with Google. Coop sends a verification link on password signup; you can sign in before verifying (soft verify).

For Pro or Enterprise, start at Pricing and follow checkout to the Welcome page. Sign in with the same email you used at checkout.

Step 2 — Install the extension

See Install the VS Code extension for marketplace and manual install options.

Step 3 — Sign in

  1. Extension UI — Open Coop sidebar → gear icon (or CoopAI: Open Settings).
  2. Account — Choose a sign-in path:
Account sign-in in VS Code — Continue with Google, email, and SSO
PathSteps
Continue with GoogleClick the Google button at the top
Continue with emailEnter email → Continue with email → password → Sign in
Sign in with SSOEnterprise: enter Organization nameSign in with SSO → finish in your browser
  1. Success: Account shows your org and plan. Open chat and ask a question.

Enterprise SSO: Organization name is required before Sign in with SSO. Coop opens your system browser for IdP login; VS Code completes the session when you return. Name matching is case-insensitive.

Automation API keys are for CI/scripts only — create them in the admin portal if needed, not in the extension.

Step 4 — Ask your first question

Open the Coop icon in the activity bar. Type in the composer, open Workflows in the chat header, or type / for commands.

  1. Open a file in your workspace. Coop shows it as the L (local) or R (remote) context chip above the composer — see Active file context chip.
  2. Extension UI — Type a question in the chat composer (plain chat works with a file chip).
  3. Try: Explain this file. What are the main entry points nearby?

Coop streams an answer grounded in your workspace files and any connected integrations. Plain chat uses GPT-5 mini — see Model assignments.

Step 5 — Try a quick action

File-scoped actions (with a file open): highlight a few lines, then right-click the selection. Choose CoopAI: Trace Decision for Selection (or Find Owner, Blast Radius, Knowledge Gaps). You can also open Workflows in the chat header, or type /trace in the chat composer.

VS Code editor context menu — CoopAI quick actions for the current selection

Understand Repo is different — it is repo-wide only and ignores a file chip:

  1. Extension UI — Open the remote file / repos picker.
  2. Select the repository (not a file) and click Use repo.
  3. Open Workflows → Understand Repo, or type /understand (aliases: /repo, /architecture, /explain). Success: repo-only chip and the action enabled.
Remote workspace — open the repos picker to choose a repository
1 — Open the repos picker
Remote workspace — repository selected before Use repo
2 — Select the repository (not a file)
Repo chip active — Understand Repo and /understand available
3 — Repo chipped — run **Workflows → Understand Repo** or `/understand`

Quick actions route to Claude Sonnet 4.6 for structured, repo-grounded answers. Full detail: Owner's Manual — Understand Repo.

Inline autocomplete

CoopAI shows ghost-text code completions by default as you type.

The sidebar header shows Autocomplete On for most installs. To turn it off: click Autocomplete in the header, or open CoopAI SettingsPreferencesModel & chat and uncheck Enable inline autocompleteSave model settings.

Model & chat — Enable inline autocomplete
Inline autocomplete — ghost-text suggestion in the editor

Type in a code file — ghost text appears after a short pause; Tab to accept.

See Inline autocomplete for FIM, graph context (indexed repos), Copilot coexistence, and how to turn off intentionally.

Verify production (smoke check)

After sign-in, confirm the hot path:

CheckSuccess looks like
API healthBrowserapi.coop-ai.dev/health returns OK
Model & chatSettings → Preferences → Model & chat — four assigned models (Chat, Quick actions, /edit, Autocomplete), no provider picker
AutocompleteSidebar Autocomplete On → type in .ts → ghost text → Tab accepts
Edit mode/edit add a comment above this functionApply / Undo on the patch notification
Create pull requestAfter Apply or after typing in a Use-repo file, click Create pull request or type Create a PR in chat → confirm branch, title, and notes → a link to the PR
Quick action (file)/trace on a selection → structured answer with sources
Understand RepoUse repo on the repository → Workflows → Understand Repo or /understand → repo-wide overview
Plain chatComposer question → grounded reply (GPT-5 mini)
