Show HN: Breadcrumb, record everything on your mac + context manager for AI
Introducing Breadcrumb: A Total Recall & Context Engine for your Mac
Breadcrumb is an AI-powered plugin designed specifically for developers. It acts as a comprehensive record of your Mac's activity, serving as a sophisticated context manager that allows you to dictate rules, shortcuts, and scopes for your AI assistants.
📂 Managing Context via "Scopes"
A scope is essentially a folder tied to a specific set of behavioral rules. When you are working within a scoped directory, the associated rules are applied to your AI automatically.
| Scope Path | Rule Count | Note Count |
|---|---|---|
/ (Global) | 22 | 88 |
/acme | 28 | 70 |
/myapp | 91 | 269 |
/personal | 0 | 4 |
Compatible with: claude, chatgpt, cursor, and opencode.
🖥️ Visual Memory & Screen Awareness
Your AI no longer guesses; it remembers exactly what appeared on your screen. For instance, if you were managing local snapshots, the AI knows the exact state of your system:
System Context Example: To view your current snapshots, you can execute:
tmutil listlocalsnapshots /To wipe them clean, use:
tmutil deletelocalsnapshots /Note: These are currently consuming of disk space.
📅 Chronological Awareness
Breadcrumb tracks your day so your AI understands your workflow.
Standup Summary (09:32):
- Priority: Ella needs a walkthrough of the retailer bug as soon as possible.
The most intense focus period was the 3h 40m spent on the landing page during the afternoon.
🔄 Seamless Session Continuity
When a long conversation becomes too bloated and the AI gets overwhelmed, Breadcrumb allows a new chat to pick up exactly where the previous one stalled.
- Session: Landing page footer 15:19 · 1h 42m · 38 turns
- (a) Continue (a?) More info
- Session: Loyalty dashboard totals Yesterday · 3h 10m · 64 turns
- (b) Continue (b?) More info
- Session: Speaker elimination Tuesday · 55m · 19 turns
- (c) Continue (c?) More info
- (s) View all other sessions
🛠️ Rules and Shortcuts
Dynamic Rule Creation
If you correct your AI, Breadcrumb suggests turning that correction into a permanent rule.
Proposed Rule:
Never push main“Never push main, merge, publish, or release without my explicit word.”
One-Word Shortcuts
Any repetitive workflow or complex instruction can be condensed into a single keyword.
- Example Workflow:
- 15m Standup
- 4h 10m Loyalty dashboard
- 4h 20m BUG-292
- Total: 8h 45m
- Action: Would you like to make this a one-word shortcut?
🔒 Privacy & Local Architecture
Breadcrumb operates on the principle that .
- Local Intelligence: Transcription, speaker identification, and daily organization are handled by models running directly on your Mac.
- Zero Data Transfer: No data is sent to the developers. The only communication is a daily update check that contains no identifying information.
- No Voiceprints: Speaker naming is derived from on-screen visual cues, not biometric voice data.
- Granular Control: You can explicitly exclude specific apps, websites, or sensitive phrases from being recorded.
