Switch Claude accounts. Keep your flow.
Save your accounts, see their usage, and bring useful context into your next chat—all from one browser extension.
- Switch and organize accounts. Save, rename, search, and pin your Claude logins. Switch in a click, cycle with shortcuts, or quick-switch to the account with the most available session quota in the latest usage data.
- See usage and reset times. Check session, weekly, and model limits where Claude provides them. Refresh one account or all of them, and get a desktop alert when an exhausted session resets.
- Keep accounts ready. Choose background refresh every 4, 8, 12, 24, or 48 hours. Expired or revoked logins may still need you to sign in again.
- Export your conversation. Download a ZIP with a Markdown transcript, thinking, and optional images, code, artifacts, and attachments. The save confirmation shows the actual full file path. Raw exports need no AI API key.
- Create a Gemini handoff. Preview and copy a summary for your next chat using your own API key, encrypted locally. Summaries send selected conversation content and optional file/code context to Google; Google's terms and charges apply.
- Back up with a password. Create encrypted v2 account backups with a confirmed password of at least 12 characters. Restore v1 encrypted files or older unencrypted backups after reviewing and confirming the account list. HotSwap never saves or recovers the backup password. See the backup format.
- Choose your theme. Use Midnight, Claude Light, or Claude Dark.
Each Claude account keeps its own plan and limits. Switching does not move the original conversation; export or summarize its context and bring it into a new chat yourself.
- Sign in to Claude, open HotSwap, and save your current account with a label you recognize.
- Choose Start new account, sign in to another account, and save it too.
- Click a saved account or use a shortcut. Check usage in Accounts, export or summarize in Tools, and manage preferences in Settings.
Default shortcuts: Alt + Shift + → / ← to cycle, and Alt + Shift + 1 to quick-switch. On Mac, use Option in place of Alt. Customize shortcuts in your browser.
Version 1.3.2 supports Claude's redesigned UI. It exports the displayed branch, original files, and an export-report.json alongside the Markdown transcript. An _INCOMPLETE filename and warning identify content or files that could not be recovered. The export task continues after the popup closes; its details tab provides progress and cancellation. Live Brave acceptance verified a 2,000-line conversation and 43 files. See development status for validation evidence.
After updating an older build, reload your open Claude tabs to remove the previous page's download hooks.
Saved accounts and settings stay in your browser. Your saved Gemini key is encrypted with a browser-managed key and unlocks automatically in the background. Optional summaries communicate directly with Google; account and usage requests go directly to Claude. The extension has no analytics or tracking.
Account backups contain sensitive login data. Keep the encrypted file and its password safe. Local encryption does not protect against someone with control of your browser profile or device.
