Build the thing
you've been putting off.

Every decision, every dead end, every rule you set gets distilled into one on-device brain. The Ledger is that brain made visible. Each session adds a crumb: what was done, how long it ran, how much context was used. Day 40 starts knowing everything from days 1 through 39.

It's not a dashboard you have to log into. It's a local record, always there, always yours. Come back after two weeks. The trail is still waiting.

This is the thing that stops the spiral. The context level gauge shows you how full Claude's working memory is in real time. When it gets high, Crumb tells you to wrap cleanly before the AI forgets what you decided this morning.

Most sessions go off the rails because nobody told you the context was full. Twelve half-built features deep. Crumb tells you before it's a problem.

Switch between projects without losing the trail on either one. Crumb keeps each project's session state separate, so jumping from your client deposit tracker to your portfolio site doesn't make Claude re-walk ground it already covered.

The gold dot in the sidebar shows where you are right now. No confusion about which session is doing what.

Prompts, pointers, and one-click buttons that auto-populate your session and wire real skills and features straight into your project. "Always keep the design minimal." "Make it mobile-friendly." Once saved, they're in arm's reach. You stop guessing. You start building.

Crumb doesn't care if you know what a merge conflict is. It cares if you shipped the thing.

Crumb runs on one rule: what you do here stays here. No telemetry. No analytics. No reading your code. Your Ledger entries stay on your machine. Your prompts go to Anthropic the same way they always have. We don't touch them.

The Quiet Pledge isn't a legal footnote. It's a plain-language promise, written to be understood, not survived.

Crumb watches your Claude Code sessions in real time. When a session ends, it preserves the record automatically. You don't press save. The crumb goes in the Ledger and it's there the next time you open the project. Crumb never forgets.

Lost a session before? You won't again.

Creative mode is for building things. Nerd mode is for the people who want to tinker with how things get built. If you're not sure which one you are, you're the first one.

Crumb doesn't make you choose upfront. Start in Creative mode. Flip to Nerd mode if you ever want to. Both unlock fully with one purchase. No features held hostage.

Creative mode strips the interface down to what matters for building: describe it, watch it get built, find it later. No visible configuration. No jargon. Nothing to configure before you can start.

Nerd mode surfaces the full controls for people who want them. Same app, more visible.

Crumb is a native macOS app that organizes your Claude Code sessions. It keeps track of your context level, saves your session history in the Ledger, and makes it possible to pick up exactly where you left off. You never see a terminal. Crumb is the window you actually use.

You don't need to know how to code. The reason you couldn't build software before wasn't that you weren't technical enough. It's that the tools assumed you already were. Crumb doesn't. You describe what you want in English. That's all.

Claude Code is excellent. The terminal is genuinely intimidating if you didn't grow up in one. Crumb is the macOS app that removes that completely. You get all of Claude Code's capability in a normal Mac window.

Crumb also adds things the terminal can't: a live context gauge so you know when a session is about to hit its limit, the Ledger so every session leaves a permanent record, and project organization so you're not starting from scratch every time.

Cursor and Windsurf are AI-augmented code editors. They live inside the IDE and give you autocomplete, inline suggestions, and chat while you write code. They're great for developers who already work that way.

Crumb is not an editor. Crumb organizes Claude Code sessions. Long-running autonomous tasks. Context history. The Ledger. Crumb is specifically for the person who wants to direct Claude Code without learning an IDE. Many developers use both.

Crumb uses your existing Claude subscription or API key. It doesn't include Anthropic credits. If you have Claude Pro or a Claude Max plan, Crumb plugs into that. If you don't have one yet, you sign up at anthropic.com before or after installing Crumb.

Crumb is a separate purchase from your Claude subscription. You pay once for the app. Anthropic bills you for Claude usage. The two are independent.

No. Most people never touch it. Crumb has two modes: Creative and Nerd. Creative is for building things in plain English. Nerd is for the people who want to tinker with how things get built.

If you're not sure which one you are, you're Creative. Nerd mode is fully there if you ever want it. Both unlock with one purchase. You don't pay extra for it.

The Ledger is the per-project history of everything you've built. Each session you close adds a crumb to the Ledger: what was done, when, how long it ran, how much context was used. It's shown as a bar chart, one bar per day.

The Ledger lives entirely on your machine. Never sent anywhere. You can see your complete project history without logging into anything. Come back after two weeks off and the trail is still there, exactly as you left it.

Yes. One license activates on up to 3 Macs. If you need to move it from an old machine to a new one, deactivate on the old machine from your account page and reactivate on the new one. The 3-activation limit is per license, not per calendar year.

Crumb itself works offline. The Ledger, your project list, session history: all of it is local and available without a network connection. The only thing that requires internet is running a Claude Code session, because that calls Anthropic's service.

Your data is always accessible. Your work is always there. You just can't start a new session without being online, because Claude needs to be there too.

The Quiet Pledge is Crumb's one-page data commitment. The short version: Crumb doesn't read your code, doesn't send your project files anywhere, and doesn't train on your sessions. Your Ledger entries stay on your machine. Your prompts go to Anthropic the same way they always have. Crumb never sees them.

It's not a terms document. It's a plain-language promise, written to be understood, not survived. Every outbound connection is listed.

Your project files are already on your machine, in the folders you opened. They don't live in Crumb. They live wherever you put them. If you stop using Crumb tomorrow, your code is exactly where it was before you installed it.

Crumb's own data (the Ledger, session records) is stored in a standard location on your machine. You can read it, back it up, or delete it. We don't hold anything hostage.

macOS 13 (Ventura) or later. Apple Silicon or Intel. Crumb is a universal binary so it runs natively on both. The app is 4 MB, signed, and notarized by Apple.

Yes. The free version of Crumb gives you one project in Creative mode, full access, forever. Nerd mode is visible inside the app so you can see what's there, but you can't start projects in it or use its features until you upgrade. No card to install. No card to use the free version.

$39 one-time or $4.99/month. Both unlock everything. The price you pay today is the price for this major version. When a new major version ships (roughly 18-24 months), existing one-time buyers get a discounted upgrade at $19. Monthly subscribers stay at the same rate.

Crumb is not VC-funded. We're not going to change what makes it good. The pricing is built to stay sustainable without being predatory.

Yes. MCP (Model Context Protocol) and hooks are Nerd mode features. MCP is a structured way to give Claude access to specific tools and data sources. Hooks are scripts that run before or after Claude Code actions.

If you didn't understand any of that, you don't need Nerd mode yet. Creative mode handles everything you need to build real things without touching any of this.

Crumb is built for individuals. No team features, no seats, no collaboration layers. Just you and your projects, organized.

The people who get the most out of it are solo builders who run a lot of long sessions and need to track what's been done. Developers who already live in a terminal use Crumb for the Ledger and the context gauge. Non-developers use it for everything. Both are the right answer.
