Cairn — Claude Export by Blacktrace

About

Stop hitting Ctrl+A.

Cairn drops your active Claude session onto your hard drive in under 200ms. It outputs clean, structured files ready for your codebase, preserving the data integrity that manual copy-pasting destroys.

⚙️ CORE CAPABILITIES
- Full Context Preservation: Captures prompts, outputs, 'thinking' blocks, and raw code artifacts. All of it.
- Native Extraction: Executes a direct, same-origin fetch. No fragile DOM scraping.
- Format Flexibility: Export exactly what you need—Markdown (.md), raw JSON, or isolated Artifacts in a .zip.
- Credential Redaction: Protect your IP. An optional parser scans and masks high-confidence secrets before they hit your disk: API keys, auth tokens, JWTs, and PEM private-key blocks.
🛡️ STRICT DATA CUSTODY
Cairn operates entirely within your browser's local execution environment.
- Zero telemetry.
- Zero third-party servers.
- Zero external network egress.
Your data routes strictly from the active tab, through the browser's native download API, directly into your filesystem.
⚠️ KNOWN LIMITATIONS (v0.3.x)
- Media Handling: Does not export raw PDFs or images (retains filename references only).
- Scope: Operates strictly on the single, active conversation tab.
