Sidekick Tools (Beta)

Sidekick can now connect to the tools your team already uses and pull context from them directly inside a support conversation.

7 integrations are available at launch: Linear, Sentry, Incident.io, Notion, Granola, Datadog, and Slack, with more rolling out over the coming days.

Alongside tool integrations, a few other capabilities are shipping with this release:

  • GitHub code access — install the Plain Sidekick GitHub App to give Sidekick read access to selected repos. Sidekick can read files and search code across your codebase.

  • File attachments — attach files to a Sidekick session; Sidekick can also generate files (CSVs, charts, reports) and share them as downloadable outputs.

  • Custom system prompt — append workspace-level instructions to shape how Sidekick behaves for your team.

  • Visible tool calls — Sidekick's reasoning steps and tool lookups are shown in real time as it works.

Tool integrations are currently read-only. Integrations are Beta, but we're expanding integration breadth based on early feedback before a wider rollout.

To connect your first integration, go to Plain AI → Sidekick → Integrations. Learn more at plain.com/sidekick
