Sidekick Tools & Integrations
NEW: Sidekick Tools is currently available in beta with new integrations being added in the coming weeks.
Sidekick can connect to the tools your team already uses and look up context from them, directly inside a support conversation. Instead of switching tabs to check Linear, GitHub, Datadog, or Notion, you ask Sidekick and it surfaces what's relevant.
How to connect an integration
You need to be a workspace Admin or Owner to connect integrations.
Go to Plain AI → Sidekick → Integrations
Find the integration you want to connect and click Connect
Complete the authentication flow (you may see Composio branding on the authorisation screen, which is expected)
Once connected, the integration is available to everyone in your workspace immediately
To disconnect an integration, return to the same page and click Disconnect.
How integrations work in a session
You don't need to configure anything per session. When you open Sidekick, it automatically discovers which integrations your workspace has connected and uses them as needed.
As Sidekick works, you'll see its tool calls on screen, so you can follow what it's looking up and why.
Visible tool calls
As Sidekick works, you can see its tool calls on screen in real time: what it's searching, what it's checking, and what it found. This gives you full visibility into how it arrived at its answer.
Supported integrations
The integrations below are all connected through Plain AI → Sidekick → Integrations.
Issues & Incidents
Integration | What Sidekick can do |
|---|---|
Linear | Search issues, look up issue status, find related projects and cycles |
Incident.io | List active incidents, get incident details |
Code access
Integration | What Sidekick can do |
|---|---|
GitHub | Read files and search code across selected repos |
Knowledge & Meetings
Integration | What Sidekick can do |
|---|---|
Notion | Search pages and databases for documentation and runbooks |
Granola | Access AI meeting notes and summaries |
Slack | Search channels, look up users |
Observability
Integration | What Sidekick can do |
|---|---|
Datadog | Query metrics, logs, and monitor status |
Sentry | Look up errors and exceptions, find related events |
More integrations are rolling out over the coming days.
GitHub code access
You can give Sidekick read access to selected GitHub repositories so it can help troubleshoot technical issues with real code context. It can answer questions about how features work, trace error paths, and explain implementation details based on your actual codebase.
This is separate from the Cursor integration. Cursor's integration uses Cursor's AI cloud agents and requires a Cursor Pro plan. GitHub access gives Sidekick direct read access to your repos via a GitHub App, with no Cursor account needed.
You need to be a workspace Admin or Owner to set up GitHub access.
Go to Plain AI → Sidekick → Integrations
Click Install GitHub App. You'll be taken through an authorization flow to install the Plain Sidekick GitHub App on your GitHub organisation
Select which repositories Sidekick may read
Optionally add workspace-level instructions to guide how Sidekick uses the codebase (e.g. which repos contain what, coding conventions, areas to be cautious about)
Optionally add per-repository instructions for repos that need specific context
Once set up, GitHub access is available to everyone in your workspace, with no per-user configuration needed.
What Sidekick can do with code access
With GitHub access connected, Sidekick can:
Read files and follow code references across selected repos
Answer questions about how a specific feature is implemented
Trace error paths and explain what the code does when something fails
Suggest troubleshooting steps based on the actual code
Good questions to ask:
"How does the password reset flow work?"
"What happens when a payment fails?"
"What API endpoints handle authentication?"
"What error handling do we have for webhook timeouts?"
Sidekick only has access to repos you've explicitly selected during setup.
Beta notes
Sidekick is generally available; the Tools capability (including these integrations) is in beta.
All integrations are currently read-only. Sidekick looks up and surfaces information but cannot take actions in connected tools.
Write capabilities are coming soon.
