One Source of Truthfor Every Claude Project.

Create reusable context once, then keep it organized and in sync across the Claude Projects that use it.

The Big Idea

Your projects are for doing the work. Your context should not be trapped inside them.

Company information, product knowledge, brand rules, coding standards, research, and instructions often get copied into multiple projects. Depot separates reusable context from the projects that consume it.

Shared Context (Source)

  • Company Context.mdCore knowledge
  • Brand & Voice Rules.mdGuidelines
  • API Specifications.jsonTechnical
  • System Instructions.mdPrompt base
1-Click Sync

  • Product EngineeringFeature Specs
  • Customer SuccessSupport & FAQs
  • Sales EnablementPitch & Decks
One source of truth

Create and update canonical knowledge in one shared library instead of copying files into ten projects.

Zero context drift

Sync updates across every connected project in one click so all workspaces stay aligned.

Clean project workspaces

Claude Projects stay focused on task execution without messy duplicates or obsolete drafts.

Product Features

Everything you need to manage your Claude context

Five dedicated tools designed specifically for the claude.ai Project workflow.

Feature 01

Create your context once. Reuse it everywhere.

Keep company docs, product specs, brand guidelines, competitors, prompts, and other reusable knowledge in Shared Libraries. Connect them to the Claude Projects that need them.

One change. One place.
  • Organize master context files into reusable topic groups
  • Connect multiple Claude Projects to one or more shared libraries
  • Inspect file inventories across all projects from the side panel

Feature 02

Update once. Keep every connected project current.

When shared context changes, see what is out of date and sync the updates across connected projects instead of re-uploading files one by one.

Smart diffing with zero file loss.
  • Push updates to 10+ projects in a single click
  • Smart diff engine updates changed files while keeping unique project docs safe
  • Live sync indicators show exactly which projects are up to date
Shared Context Group: Core Specs 1 Outdated
  • Company Context.mdModified in Library
  • Brand Guidelines.mdUp to date
  • API Spec.jsonUp to date

Feature 03

Test changes without breaking what works.

Create a copy of a Claude Project with its instructions and context, preview what will be created, and experiment safely without touching your original.

Experiment fearlessly.
  • Pre-flight preview of document and instruction counts before cloning
  • Auto-suggests clean variant names like (variant B)
  • Your original working project remains completely untouched

Feature 04

Fix your context without leaving Claude.

Open a project document, make the change, and save it back directly from the side panel. No delete-and-re-upload loop.

Immediate in-app editing.
  • Edit Markdown, JSON, SQL, and code files directly inside Claude
  • Live character counter tracks size against Claude project limits
  • Save immediately with Cmd+S or Ctrl+S without page reloads

Feature 05

Own the context you have built.

Back up your Claude Projects to your computer and restore them later when you need them. Your context belongs to you, not locked into a single browser session.

Local file ownership.
  • Download structured .zip archives containing instructions.md and docs/ folder
  • Export single project backups or full workspace archives
  • Restore projects with full fidelity to new or existing containers

Trust & Privacy

Your context stays with you.

Depot runs locally in your browser and talks directly to claude.ai. No external backend, no account, and no tracking.

100% local execution

All logic runs in your browser extension sandbox with zero remote servers.

Direct Claude connection

Only communicates with official Anthropic web session endpoints on claude.ai.

No extra account

Uses your existing active login. No passwords, tokens, or API keys needed.

Zero telemetry

No analytics, no tracking scripts, and no external network calls.

Who it is for

Built for people who actually work in Claude Projects.

Designed for operators, engineers, consultants, and researchers who rely on Claude daily.

Founders & Operators

Keep company and product context consistent across marketing, sales, and operations.

AI Builders & Prompt Engineers

Experiment with prompt variations and instruction sets without losing working setups.

Consultants & Agencies

Reuse frameworks, manage distinct client knowledge bases, and move setups between workspaces.

Researchers & Knowledge Workers

Organize reference libraries, edit notes on the fly, and archive project snapshots locally.

Honest limits

Works with Claude limits, not around them.

Depot is designed around what Claude actually supports. Text and instructions can be managed and restored fully; some platform limitations remain outside Depot control.

Text and code are 100% faithful

System instructions, Markdown, JSON, SQL, and code files are backed up, cloned, and restored byte-for-byte.

Image files stay in Claude

Claude converts uploaded images into downscaled WebP previews and provides no endpoint to re-upload image files via script. Depot preserves previews and reminds you to re-add raw images manually.

Uses your existing session

Depot runs internal Claude requests using your active login. No Anthropic API keys, tokens, or credit cards needed.

Saved in your browser

Library groups are stored in local extension storage (chrome.storage.local). You can export and back them up to .zip at any time.
