Ctxport
Free, open-source Chrome MV3 extension that copies AI conversations into structured Markdown Context Bundles, entirely on your machine.
Ctxport is a genuinely useful, zero-cost utility: it turns a 45-minute ChatGPT thread into a structured Markdown file you can paste into Claude, your IDE, or your note app for $0. Sidebar list copy — grabbing a conversation without opening it — and the Alt+Shift+C shortcut are the two features that make it faster than manual copying, and with 100% local processing plus an MIT license you can verify the privacy claim by reading the source. The catch is installation: it isn't a Chrome Web Store one-click install, so you sideload the MV3 ZIP through Developer mode. If you need a bundled workspace with cloud backup, sharing, and mobile apps, look at Mem or Taskade instead — Ctxport does one

Skip Ctxport if you need conversations captured on mobile, synced to the cloud automatically, or shared in a team library — it's a Chrome-only, local-only clipboard utility with a manual Developer-mode install.
Ctxport is $0 — no tiers, no seats, no usage caps, no add-ons — because it's an MIT-licensed extension rather than a hosted service. Compared with paid conversation-management workspaces like Mem or Taskade, which bill per user per month for cloud storage, sync, and collaboration, Ctxport is free but covers only the copy-out step; you supply the destination (a notes app, a repository, a shared drive).

What is Ctxport?
Ctxport — Free, open-source Chrome MV3 extension that copies AI conversations into structured Markdown Context Bundles, entirely on your machine. Best for AI power users who switch between multiple chatbots, Developers pulling code snippets out of AI chats, Researchers and writers archiving conversations as structured Markdown. Free to use.
Ctxport is a free, MIT-licensed Chrome extension that copies a whole conversation from ChatGPT, Claude, Gemini, DeepSeek, Grok, Doubao, or GitHub Copilot into a structured Markdown document with one click. It replaces the usual Ctrl+A / Ctrl+C mess — HTML residue, broken formatting, invisible characters — with a Context Bundle: YAML frontmatter (title, source, url, timestamp, message_count) followed by every message as a Markdown heading, with fenced code blocks keeping their language tags and indentation. The standout capability is sidebar list copy: you can copy any conversation straight from your chat history list without opening it, alongside an in-chat copy button and the Alt+Shift+C shortcut. Four export formats cover different jobs — Full (frontmatter plus all messages) for moving context between AI tools, User Only (frontmatter plus your messages only) for re-prompting another model, Code Only (all fenced code blocks extracted) for dropping snippets into an IDE, and Compact (messages without frontmatter) for quick pastes into notes. There's no sign-up, no account, and no data upload: it runs 100% locally in your browser, requests access only to the supported AI platform domains, and works offline after install. It is built and maintained by Jinming Yang (nicepkg) and the source is readable on GitHub under the MIT license. The trade-off is installation: you download the MV3 ZIP from GitHub Releases and load it unpacked via Chrome Developer mode rather than installing from the Chrome Web Store. It's a browser utility, so there is no cloud sync, no collaboration, no mobile or desktop app, and no API — and it is Chrome-only.

Limitations
- Ctxport is a free, open-source Chrome extension that runs 100% locally, requires no account, and uploads zero data — all processing happens in your browser, with no servers, cloud, or telemetry.
- It works only on the supported AI platform domains (ChatGPT, Claude, Gemini, DeepSeek, Grok, Doubao, GitHub Copilot).
- Installation is manual: download the MV3 ZIP from GitHub Releases, enable Developer mode at chrome://extensions, and Load unpacked — there's no Chrome Web Store one-click install.
- It is a browser extension rather than a service, so there is no API, no cloud sync or backup, no mobile or desktop app, and no team collaboration or shared libraries.
- Output is text you paste elsewhere; the archive lives wherever you put it.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Ctxport actually fits — and what changes day-one when you adopt it.
You finish a 40-message ChatGPT thread on a REST API design and want Claude to implement it. Instead of selecting and copying the page, you press Alt+Shift+C in the ChatGPT tab and get a Markdown Context Bundle with YAML frontmatter (title, source, url, timestamp, message_count) and every message preserved as a heading.
Outcome: You paste the whole bundle into Claude as one message; the code blocks keep their language tags and indentation, so the second model starts from your full context rather than a summary.
You have a DeepSeek conversation full of working snippets. You right-click, choose the Code Only format, and Ctxport writes out just the fenced code blocks.
Outcome: You drop the code straight into your editor — no prose, no HTML residue, no re-indenting by hand.
You open your Gemini chat history, use sidebar list copy on a months-old research thread without opening it, and save the Full format Markdown to your notes vault.
Outcome: The conversation becomes a searchable Markdown file with frontmatter metadata, while your prompts stay local — nothing is uploaded to any Ctxport server.
Use cases
- Move a long ChatGPT conversation into Claude for implementation without losing formatting or code syntax.
- Archive a Gemini research dialogue as a Markdown file with frontmatter so you can search it later.
- Extract every code block from a DeepSeek conversation with Code Only and paste it into your IDE.
- Re-prompt a different model with only your own questions using the User Only format.
- Share a structured conversation with a teammate as one searchable Markdown file.
- Copy a conversation straight from the sidebar list without opening it, then paste into your notes app.
- Capture a GitHub Copilot chat session as Markdown before the thread gets unwieldy.
Setup time & first value
How long it actually takes to get something useful out of Ctxport — broken out by persona, not the marketing-page minute.
For a developer: about 2 minutes — download ctxport-chrome-mv3.zip from GitHub Releases, unzip it, open chrome://extensions, enable Developer mode, click Load unpacked, and select the folder. For a non-technical user, budget 5–10 minutes the first time, since Developer mode and Load unpacked are unfamiliar steps; there is no sign-up or configuration after that. First copy is immediate once the
Switching to or from Ctxport
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual Ctrl+A / Ctrl+C: install the MV3 ZIP via Developer mode and use the in-chat copy button or Alt+Shift+C to get Markdown instead of HTML residue.
- →From screenshots: use sidebar list copy to pull whole conversations into a searchable Markdown archive instead of screenshot folders.
- →From retyping context between chatbots: paste the Full format Context Bundle into the second AI tool to carry the whole thread across.
- ↗To a notes app (Obsidian, Notion, or similar): paste the Full or Compact format and let the YAML frontmatter become note metadata.
- ↗To an IDE: use Code Only to extract fenced code blocks, then commit the snippets to your repository.
- ↗To a managed conversation workspace (Mem, Taskade and similar): keep Ctxport for capture and move the archive there if you need sync and sharing, since Ctxport has neither.
