Filter by **All Apps**, **My Apps**, **Shared with me**, or **Templates**, or search by name. Each card shows what the App does, whether it's shared with you or company-wide, plus the average time it saves and how long it takes to run. The App library with filter tabs and cards showing each App's description, sharing status, average time saved, and run duration ## Run a pre-built App The App opens a guided session with a numbered stepper. Depending on how it was built, a step might ask you to type a short brief, choose from a list of options (an output language, say), pick the Brain(s) to work from, or upload a document. Fill each step and click **Continue**. The App executes its workflow block by block. Watch progress and see the output of each stage as it completes. [App Blocks](/features/apps/app-blocks) explains the statuses and run order. The finished deliverable carries the same sourcing and [one-click citations](/features/chats/sourced-answers) you get in Chat, so every claim stays traceable to its source. An App run in progress, with the numbered input stepper completed and blocks generating output Blocks that pause for review, per-passage edits, and the final export are covered in [Reviewing & Exporting](/features/apps/reviewing-and-exporting). ## Related Approve review steps, refine a block, and export the deliverable. Statuses, dependency order, and what each block draws on. Adapt a template, or build your own App from scratch.
