Claude

API sync Fast

HAEVN syncs Claude conversations via the Anthropic API. It supports the full range of Claude’s capabilities, including extended thinking blocks and tool use.

Claude’s extended thinking feature is fully supported. When a conversation includes thinking content, HAEVN preserves the complete internal reasoning. In the Viewer, thinking blocks appear as collapsible sections above the response — click to expand and read the model’s full chain of thought.

HAEVN can import Claude Code session files. These are the JSONL files Claude Code generates in your project’s .claude/ directory. Import them via the Import feature.

Note: Live sync of Claude Code sessions is not currently supported — only file-based import.

  • Starred conversations — the star status is not preserved in the HAEVN archive.
  • Projects — project-level instructions and context are not currently synced alongside conversations.
