Cairn — Claude Export by Blacktrace

Export any Claude conversation — JSON, Markdown, or a zip of every artefact Claude built. Optional secret redaction. By Blacktrace.

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. 🔗 LINKS - Website: https://cairn.blacktrace.co - Support: trace@blacktrace.co
