- Multi-platform support: works with 23 major LLM platforms.
- Single or batch export: exports the current conversation or all conversations at once.
- Incremental export: on the list page, batch export skips conversations you've already downloaded (by update-time anchor) and only fetches new/updated ones — dramatically faster on repeat runs.
- Content fidelity: exports include user messages, AI replies, reasoning / thinking, and citation sources.
- One-click save to AfterChat: on a conversation detail page, right-click the button to save the current conversation directly to your AfterChat workspace.
