Incognito Vault

Save Claude and ChatGPT incognito chats to Markdown with artifacts, keep a private local history, and resume any chat later.

Some chats are meant to vanish. Then one of them turns out to matter. Claude's incognito mode and ChatGPT's temporary chats leave nothing behind: no history, no sync, nothing attached to your account. That is the entire point of them, and it works perfectly — right up until you close the tab and realise the answer you needed went with it. There is no undo and no "recently closed". The conversation lived in one browser tab, and now it doesn't. Incognito Vault adds a save button and changes nothing else. The chat stays ephemeral on the site. A copy lands on your own disk as plain Markdown, in a folder you will still be able to open in twenty years with any text editor. ── WHAT IT DOES ────────────────────────────── ■ Saves any chat to Markdown, in one click Click "Save to Vault" at the bottom-right of the page, or open the toolbar popup and click "Save current chat". You get a real document: YAML front-matter with the title, platform, timestamp and message count, then the conversation with speaker headings, every code block fenced and tagged with its language, lists and tables and links preserved. It is Markdown, not a screenshot and not a wall of unformatted text — it opens in Obsidian, Notion, VS Code, GitHub, or Notepad. ■ Brings the artifacts with it Claude artifacts are saved into the same folder as the transcript that produced them. Code artifacts and diagrams are read straight out of the page. HTML and React artifacts — which render inside a sandboxed frame that no extension can read — are handled by pressing Claude's own download button for you, so the real file arrives complete rather than as a partial copy. Claude hands those files to the browser with no name attached, which is why saving one by hand gives you "download.md" in your Downloads root. Incognito Vault names each file after its artifact and files it next to the transcript that references it. ■ Gives ephemeral chats a real name An incognito chat is never named by the site, so a naive exporter produces a folder full of "new-chat", "new-chat (1)", "new-chat (2)". Incognito Vault reads a title out of the conversation itself. Saves land under "how-do-i-fix-a-cors-error" or "flutter-architecture-layers" — names you can actually search six months later. ■ Keeps a local history you can search Every save is listed in the toolbar popup with its platform, date, message count and artifact count. Search by title. Re-download the whole folder — transcript and artifacts — any time. Delete an entry when you are done with it, with a confirmation step so a mis-click costs you nothing. The full transcript is kept in the extension's own storage, so the history survives long after the chat itself is gone. ■ Resumes a saved chat Pick any chat from the history and press Resume. A fresh incognito or temporary session opens with the transcript already loaded into the composer, framed as context so the assistant picks up the thread instead of starting over. It is never sent automatically. You read it, trim it if it is enormous, and press Enter yourself. Sending someone's conversation on their behalf is not something an extension should do. ── HOW YOU USE IT ──────────────────────────── 1. Open a chat on claude.ai or chatgpt.com — incognito, temporary, or an ordinary one; all of them work. 2. Click "Save to Vault" on the page, or "Save current chat" in the popup. 3. The files appear in Downloads/IncognitoVault/<date>_<title>/. The button tells you what it captured — "Saved (12 msgs, 1 artifact)" — so you know at a glance whether the artifacts came along. Save before you close the tab. For an ephemeral conversation, the page in front of you is the only place it exists. ── WHAT LANDS ON DISK ──────────────────────── Downloads/IncognitoVault/ └── 2026-08-06_1243_flutter-architecture-layers/ ├── flutter-architecture-layers.md (the transcript) ├── artifact-1-layer-diagram.md └── artifact-2-dashboard.html One folder per chat. Ordinary files that you own, that no application controls, that back up and sync and grep like anything else on your computer. Delete them whenever you like — the extension neither knows nor cares. ── PRIVACY ─────────────────────────────────── No servers. No accounts. No analytics. No sync. No network requests of any kind — the extension contains no code that opens a connection, because there is nowhere for it to connect to. It reads the conversation on the tab you are looking at, only at the moment you press save, and writes it to your disk. That is the whole data flow. It asks for two permissions: • storage — holds your saved-chat history locally • downloads — writes the transcript and artifact files to your Downloads folder Plus access to claude.ai, chatgpt.com and chat.openai.com, which is where the conversations are. It deliberately does NOT request the "tabs" permission. That permission would let it see every tab you have open, and it does not need to, so it does not ask for it. An extension built to protect private conversations has no business watching the rest of your browsing.

Neither site can genuinely reopen an ephemeral chat. Resume pastes the transcript into a new session as context. A very long chat may exceed the composer or the context window, so trim it first. • Files go to Downloads/IncognitoVault/. Extensions cannot write anywhere else. Change your browser's download directory, or symlink the folder, if you want them somewhere specific. • Images are referenced by URL, not downloaded — and incognito image URLs expire, so those links will eventually go dead. • Claude and ChatGPT redesign their interfaces often. When a redesign breaks scraping, the extension says so plainly instead of silently saving nothing, and the fix is a selector update in one file. • Uninstalling removes the history. Your downloaded files stay where they are. ── WHO IT IS FOR ───────────────────────────── People who use incognito and temporary chats on purpose — for a salary question, a medical worry, a draft resignation letter, a half-formed idea, client work that should not be sitting in a chat history — and who occasionally need to keep one anyway. You should not have to choose between "this conversation is private" and "I can read this again tomorrow". Incognito Vault is an independent open-source project. It is not affiliated with, endorsed by, or sponsored by Anthropic, OpenAI, or Google. "Claude" and "ChatGPT" are named only to describe the websites the extension works on.
