# Overview

> Repeatable workflows that turn inputs into a finished, consistently formatted deliverable, every time

Apps turn your firm's methodologies, processes, and frameworks into repeatable, multi-step workflows. Where [Chat](/features/chats/overview) is for exploring, an App automates a specific workflow from end to end and produces a finished deliverable, so every team gets the same high-quality output from AI without re-explaining the method each time.

## Why it matters

A methodology that lives in one partner's head doesn't scale. An App captures it once (the inputs, the sources, the analytical steps, the output format) and makes it executable by anyone on the team. The deliverable comes out the same way on every run, regardless of who runs it.

## What you can build

You don't start from a blank page. Our AI deployment team has mapped the value chain of professional use cases into 50+ ready-made templates, spanning the deliverables professional teams produce most. Each is a starting point you replicate and edit to match your own methodology.

Together, the template library and the no-code builder form the **Use Case Factory**: start from the catalog, or build your own workflow from scratch, no coding required.

<Tip>
  When you notice yourself running the same analysis a third time, build it into an App and share it.
