Hop Claude to ChatGPT

Chat Transfer hops the open Claude thread to ChatGPT in Chrome by pasting a wrapped handoff into ChatGPT’s composer locally — Full, Last N, or last assistant — so you can continue that Claude chat without account migration and without silent-send.

Version 0.4.0 is live on the Chrome Web Store. Soft Auto-Send stays opt-in and default off. Preferences live in chrome.storage.local. Add to Chrome

What “hop Claude to ChatGPT” means here

People search “hop Claude to ChatGPT,” “continue Claude thread in ChatGPT,” or “open Claude chat in ChatGPT” for two different jobs. Chat Transfer only does the first:

Hop the open Claude thread vs full-account migration
Job	What moves	Chat Transfer
Hop current thread	The Claude chat you have open on claude.ai: Full, Last N, or last assistant → ChatGPT composer at chatgpt.com/	Yes. Copy and export stay on this device too
Full-account migration	Claude Projects, artifacts, memories, and the rest of the account — or ChatGPT history folders, memories, and custom GPTs	No
Keep two sites in sync	An ongoing mirror after the hop, including TransferLLM-style account sync	No. One hop does not watch later messages
Send	Who presses Send on ChatGPT	Paste never silent-sends. Soft Auto-Send is opt-in, default off, and asks once

The reverse walkthrough is Hop a ChatGPT chat to Claude. Same extension, same local paste; this page starts on Claude and lands in ChatGPT. Claude into Grok: Hop Claude to Grok.

Steps: Claude → ChatGPT in Chrome

Add Chat Transfer from the Chrome Web Store (0.4.0).
Open the Claude chat you want to continue in ChatGPT (a thread on claude.ai, not an empty new chat).
Open the popup or side panel → pick a hop payload (Full, Last N, or last assistant) → choose Open target / hop toward ChatGPT (or the hop-to-last-used shortcut if you bound ChatGPT last).
ChatGPT’s new-chat page (https://chatgpt.com/) gets a best-effort paste into the composer. If the box is empty, paste the hop backup yourself — Soft Auto-Send does not run on a failed land.
You click Send on ChatGPT — unless Soft Auto-Send is on (see below).

Extract runs only when you hop, Copy, or Export. Chat Transfer does not scrape Claude in the background. The wrapped hop names Claude as the source (“The following is a transcript from Claude…”) and, when the tab URL is http(s), adds a Source: line with query, hash, and credentials stripped. Copy and Export stay unwrapped — no hop wrapper and no Source: line. Longer install walkthrough: How to use.

Payload choices for a ChatGPT hop

Full — the turns read from the open Claude page, wrapped with a short continue line for ChatGPT.
Last N — the last N turns. N starts at 10. Presets set 4, 8, or 16. Useful when the Claude thread is long and you only need recent context in ChatGPT.
Last assistant — only the last assistant reply from Claude, when you want ChatGPT to react to that answer alone.

Cheap Claude chrome (Copy, Retry, thought/thinking headers) is not treated as a turn. Visible attachments become [attachment not exported: …] — file bytes are not invented, and Claude artifacts are not rebuilt inside ChatGPT.

Overflow: over about 12k characters, ChatGPT’s composer gets a short Last N (or compact) paste and the full Markdown downloads as a .md so a cut is not silent. Copy and Export stay the full unwrapped transcript — no hop wrapper.

Soft Auto-Send stays opt-in (default off)

A hop paste into ChatGPT does not silent-send. Soft Auto-Send is opt-in (hopSoftAutoSend in chrome.storage.local, default off). After a successful paste it asks once: “Send this hop now?” Confirm presses ChatGPT Send once; Cancel leaves the paste; a failed paste never asks. There is no upgrade path that turns the box on for existing installs. Full walkthrough: Soft Auto-Send. Same facts as the privacy policy (2026-10-09).

When the setting is on, Confirm is one best-effort press — not a retry loop. If Send is not pressable on the first look, Chat Transfer polls briefly (about two seconds) before one click; if that still misses, it may dispatch one plain Enter on the composer. That is the whole press budget for that hop. Try attach full.md can put a file in the box; that path still never clicks Send.

Local only — chrome.storage, no backend

Chat Transfer is a local-only Chrome extension. Settings (Demo mode, Keep system prompt, hop payload, last-used target, Soft Auto-Send) stay in on-device chrome.storage.local. There is no Chat Transfer backend; the marketing site does not receive hop text. Host access is only Claude, ChatGPT, Gemini, and Grok domains. Soft Auto-Send adds no host_permissions and no downloads permission.

This is still “this thread,” not a full-account move. Claude Projects, artifacts, and memories stay on Claude. ChatGPT history folders, memories, and custom GPTs stay on ChatGPT. A Claude→ChatGPT hop only continues the open chat you asked to transfer.

When not to use a hop

You need images, files, or Claude artifacts re-attached inside ChatGPT — hop notes them; it does not rebuild binaries.
You want background scraping while you browse — Chat Transfer only reads when you act.
You need an ongoing sync between Claude and ChatGPT accounts — that is not what hop does.

FAQ

Can I hop Claude to ChatGPT without migrating my account?

Yes. Chat Transfer hops the open Claude thread into ChatGPT’s composer on this device. It does not move accounts, Projects, memories, or later messages.

Does hopping Claude to ChatGPT silent-send?

No. Paste never silent-sends. Soft Auto-Send is opt-in, default off, and asks once after a successful paste.

Is this different from hopping ChatGPT to Claude?

Same extension and local paste model. Source is Claude and destination is ChatGPT; Soft Auto-Send and payload choices (Full / Last N / last assistant) are shared. See the reverse guide for ChatGPT → Claude.

Where does the ChatGPT hop land?

Open target opens ChatGPT’s new-chat URL (https://chatgpt.com/) and pastes there. It does not append into an existing ChatGPT conversation, and it does not keep the two threads in sync after you send.
