# Navigating the Platform

> A map of the ProDex interface: the top navigation, the left sidebar, and how Dexter follows you across every page.

## Overview

ProDex opens on the **Chat** surface, with [Dexter](/product/ai-assistant) ready to go — that's the app's front door and where most work starts. Around it, the chrome has three pieces you'll use constantly: a **top navigation bar** for the four primary surfaces, a **collapsible left sidebar** that maps every capability in the platform, and a **factory selector** at the top of that sidebar that scopes everything you see to one workspace.

This page is a map of that chrome, item by item. If you're new to the underlying terms (Factory, model, run, project), read [Key Concepts](/getting-started/key-concepts) first.

## The Four Top-Nav Surfaces

Across the top of the window, left to right:

* [**Chat**](/product/dexter/chat-and-tasks): your conversation with Dexter, and the default landing page. Multi-turn chat with tasks, review briefs, and action cards inline.
* [**Knowledge Base**](/product/dexter/memories): Dexter's durable memory of your operation — how your factory runs, what your data means, and what has been built in the platform. Auditable and editable.
* [**Workflows**](/product/dexter/custom-workflows): the catalog of built-in and custom workflows Dexter can execute — simulation modeling, planning, exploratory data analysis, reports, CAD analysis, and any procedures your team has saved.
* [**Projects**](/product/dexter/projects): the home for durable, multi-session efforts (a full simulation study, a multi-week model build) with phases and gated sign-offs, so Dexter can resume across sessions.

## The Left Sidebar

### Factory Selector

Below the logo, the first item is a button showing the **current factory's name**. Clicking it opens a popover with:

* A **Search factories...** box
* A **Current** entry showing the factory you're in
* An **All factories** list, where each factory has a star to mark it as a favorite
* Bottom actions: **New Factory**, **Factory files**, **Sharing**, and **Factory settings**

Selecting a factory switches your entire workspace to it — every sidebar item below becomes scoped to that factory's models, data, plans, and knowledge base, and your Chat, Workflows, and Projects context follows the switch. See [Factory Management](/product/factory-management) for creating, sharing, and exporting factories.

### Navigation Items, Top to Bottom

The sidebar is grouped with visual separators. In order:

| Group    | Item                                                 | What it opens                                                                                                                                                                                                                                                               |

<Note>
  There is no **Insights**, **Scheduling**, or **Settings** item in today's sidebar. Exploratory dashboards are produced through Dexter's [Exploratory Data Analysis](/product/exploratory-analysis) workflow, and user preferences moved to the avatar menu at the bottom of the rail.
</Note>

### Bottom Cluster

At the bottom of the sidebar, in order:

* **Notifications**: the in-app notification center
* **Feedback**: send feedback to the ProDex team
* **Tour**: starts a guided walkthrough of the page you're currently on (steps are page-scoped, e.g. "Left navigation, Step 1 of 3")
* [**Team**](/product/team-management): manage the people who share access to your workspace
* **Documentation**: opens this documentation site
* **User avatar**: shows your email; its menu contains **Language**, **Theme** (Light / Dark / System), a **Desktop notifications** toggle, and **Logout**

<Tip>
  If you ever get lost on an unfamiliar page, click **Tour**. The walkthrough is scoped to whatever page you're on, so it's the fastest way to reorient.
</Tip>

## How Dexter Shows Up Outside Chat

Dexter is not confined to the Chat page. Even on Modeler, Results, Planning, or any other surface, Dexter works alongside you:

* **Session-context awareness**: Dexter knows which page you're on and which objects you have selected — a specific model, run, or pipeline. You can ask *"why is utilization so low here?"* without restating what "here" is.
* **Tasks**: when Dexter is doing multi-step work on your behalf (profiling a dataset, building a model, running an analysis), it maintains a visible task list so you can see what's in flight, what's done, and what's next — no status-update questions needed.
* **Action cards**: when the natural next step is to open a specific surface (start a project, add data, review a run), Dexter surfaces a button-style action card in the conversation that takes you there directly.
* **Review briefs**: when Dexter needs your sign-off before something consequential — approving derived cycle times, advancing a [project phase](/product/dexter/projects), publishing a report — it presents a structured brief with an approve / request-changes decision.

See [Chat and Tasks](/product/dexter/chat-and-tasks) for the full picture of working with Dexter.

## Feature Flags

<Info>
  Not every organization sees every item described here. Some surfaces are gated per organization, so if a capability is missing from your sidebar it may not be enabled for your workspace yet — reach out to your ProDex contact if you expect to see something that isn't there.
</Info>

## Where to Go Next

* [**Your First Project**](/getting-started/your-first-project): upload data, talk to Dexter, get your first artifact
* [**Your First Simulation**](/getting-started/your-first-simulation): build and run a model end to end
* [**Key Concepts**](/getting-started/key-concepts): the vocabulary the rest of the docs assumes
