会话记录在这些地方（~ 是用户目录，Windows 上是 C:\Users\你的用户名）：

Claude Code

~/.claude/projects/<项目>/<会话id>.jsonl

Codex

~/.codex/sessions/<年>/<月>/<日>/rollout-*.jsonl

Kimi Code

~/.kimi/sessions/<项目>/<会话>/context.jsonl

Antigravity

~/.gemini/antigravity/brain/<id>/.system_generated/logs/transcript.jsonl

claude.ai

设置 → 隐私 → 导出数据，邮件里的压缩包解开是 conversations.json

ChatGPT

设置 → 数据管理 → 导出数据，同样取 conversations.json

这些文件夹是隐藏的。Windows：在选文件窗口的地址栏粘贴 %USERPROFILE%\.claude\projects 回车。macOS：按 ⌘⇧G 输入 ~/.claude/projects，或 ⌘⇧. 显示隐藏文件。最新的会话一般是修改时间最近的那个。

Where the session logs live (~ is your home folder; on Windows that's C:\Users\<you>):

Claude Code

~/.claude/projects/<project>/<session-id>.jsonl

Codex

~/.codex/sessions/<year>/<month>/<day>/rollout-*.jsonl

Kimi Code

~/.kimi/sessions/<project>/<session>/context.jsonl

Antigravity

~/.gemini/antigravity/brain/<id>/.system_generated/logs/transcript.jsonl

claude.ai

Settings → Privacy → Export data; unzip the archive from the email and take conversations.json

ChatGPT

Settings → Data controls → Export data; same conversations.json

These folders are hidden. Windows: paste %USERPROFILE%\.claude\projects into the file picker's address bar and press Enter. macOS: press ⌘⇧G and type ~/.claude/projects, or ⌘⇧. to show hidden files. The newest session is usually the most recently modified file.
