Works where you work

Run checks, design reviews and Runner from the tools you already open. Connect your stack once, and findings land where your team already looks.

Connect your stack

Each connection sets up in the same three steps: your account, your workspace, then the projects that use it.

Slack
Drop a page or Figma link in a channel and the design review comes back in the thread. Run summaries and alerts land there too.
Linear
Findings become issues in your backlog, and the Linear agent sets up checklists and automations when you ask.
GitHub
Start an automation when a pull request merges, and see the result on the pull request that shipped the change.
Figma
Create a project from a Figma file, then review and interview against the design before any code exists.
Vercel
Point a checklist or interview at your newest deployment. Each run finds the latest build, with protection handled for you.
Claude, ChatGPT and Cursor
Connect the MCP server and checklist runs and Index reports come back as cards, right in the conversation.

Reviews, checks and answers arrive in the conversation you started, not in another tab.

Design review in the thread you asked in
Map a Slack channel, drop in a link to a page or Figma file and ask for feedback. Your default actor uses the product, opens the menus and follows the flow, and the findings come back in the thread, ordered by severity.
Design review in Slack
Ask for a check, get one that runs
Runner and the Slack and Linear agents create and update projects, actors, checklists, interviews and automations for you. Ask for a nightly checkout check and you get one that runs, and follow-up questions keep their context.
Automate with MCP
Your coding agent knows when to verify
Install the plugin or the skills in Claude Code, Cursor or Codex, and your agent knows when to verify a change, run an interview or audit a page, without leaving the editor.
