Give Chrome a memory. TabX quietly remembers every page you read and recalls it by meaning — not keywords. Replay research as journey-map timelines, @mention any tab, stack or timeline to chat with cited answers, auto-group tabs into color-coded stacks, get scroll-synced page summaries, and search the web ad-free. Rated 4.9★ on the Chrome Web Store. 7-day free Pro trial, no card required. ## Who TabX is for - Heavy-tab knowledge workers and researchers who run 20–100+ tabs and lose track of where information lives. - Developers and technical users working across ChatGPT, GitHub, docs, Gmail, and YouTube at once. - Anyone who did research days or weeks ago across many tabs and now needs to find it again fast. - People who want AI recall, chat, and ad-free search without switching away from Chrome to a new browser. ## What TabX does - **Recall by meaning** — Find a page you read weeks ago by describing it — semantic search matches intent, not exact keywords, even on pages you already closed. - **Journey-map timelines** — Your visits auto-organize into named research sessions; one click rehydrates every page in the order you browsed them. - **@mention chat with cited answers** — @mention any tab, stack, or timeline and ask — answers stream in grounded in the pages you actually read, and cited back to them. - **Color-coded intent stacks** — Open tabs auto-cluster into named, colored Chrome groups so you can reopen a whole set at once — no manual tagging. - **Scroll-synced summaries** — A live page summary plus a “Now Reading” blurb that follows your scroll, section by section. - **Ad-free AI web search** — Flip to Online for 3–5 hand-ranked links with a collective answer on top — geo-localized and streamed in about a second. - **Land on the exact passage** — Click a result and TabX opens the tab, scrolls to the sentence, and highlights it — battle-tested even on ChatGPT, Gmail, GitHub, WhatsApp Web and YouTube. ## How it works 1. Install the extension and sign in with Google or an email one-time passcode (one click). 2. Browse normally — TabX de-duplicates and vector-embeds every page you read into your private cloud memory. No tagging, no bookmarking. 3. Press Ctrl/Cmd + I to open the side panel on any page, then recall by meaning, @mention a tab/stack/timeline to chat with cited answers, reopen a research timeline, or flip to ad-free AI web search. ## Why choose TabX over alternatives - It is a lightweight Chrome extension, not a whole new browser — no migration (unlike Perplexity Comet, Dia, or Arc). - It remembers pages you have already closed and recalls them by meaning, not just keywords. - Its highlight-and-scroll engine is battle-tested on hard, dynamic sites (ChatGPT, Gmail, WhatsApp Web, GitHub, YouTube). - AI works out of the box with no API keys to bring; your memory is private and per-user. ## Pricing - Free — $0 forever: TabX keeps saving every page you read, plus a daily free taste of the Pro tools (up to 5 AI actions/day across recall, @mention chat, and web search). Includes a 7-day Pro free trial, no card required to begin. - Pro — $20/month: unlimited AI recall, @mention chat, ad-free web search, timelines, stacks, and nudges. - Pro — $200/year: Pro billed annually (two months free). ## Frequently asked questions ### What is TabX? TabX is a Chrome extension that gives your browser an AI memory. It quietly remembers every page you read into your own private cloud memory, then lets you recall it by meaning, replay your research as journey-map timelines, @mention any tab to chat with cited answers, auto-group tabs into color-coded stacks, and search the web ad-free. ### How do I search across all my open Chrome tabs at once? Install TabX and press Ctrl/Cmd + I to open its side panel on any page. Type what you're looking for and TabX searches across your open tabs and your indexed reading history — by title, URL, and page content — then jumps you to the exact match and highlights it. ### How is TabX different from Chrome's history? Chrome history is a flat list of URLs you still have to remember the title of. TabX indexes the actual content of what you read and lets you recall it by meaning rather than keywords, chat with it, replay it as a timeline, and reopen a whole research session in one click. ### Is there a Perplexity Comet or Dia alternative that doesn't make me switch browsers? Yes — TabX gives you AI recall, @mention chat, and ad-free AI search as a lightweight extension inside the Chrome you already use. There's no new browser to install or migrate to. ### Is my browsing history private? Yes. Everything you read is indexed into your own private, per-user cloud memory, and all captured content is de-duplicated so nothing is stored twice. TabX never sells or shares your data, and you can wipe it anytime by emailing tabindex1@gmail.com. ### Do I need my own OpenAI, Anthropic, or Gemini API key? No. TabX's AI runs through the platform's own model subscriptions, so recall, @mention chat, summaries, and web search all work out of the box — no keys, no setup, no per-token surprises. ### How much does TabX cost? TabX keeps saving every page you read for free, forever, plus a daily free taste of the Pro tools. Pro is $20/month or $200/year and unlocks unlimited AI recall, @mention chat, ad-free web search, timelines, stacks, and nudges. Pro starts with a 7-day free trial and no card is required to begin. ### What happens when the free trial ends? Nothing is deleted, and TabX keeps saving every page you read for free. You also keep a daily free taste of the Pro tools — up to 5 AI actions a day, shared across history recall, @mention chat, and ad-free web answers. Upgrading to Pro makes all of it unlimited, and every page you've saved becomes instantly searchable in full. ### Which sites does TabX work on? Everywhere you browse, including the hard ones like ChatGPT, Gmail, WhatsApp Web, GitHub, and YouTube. The highlight-and-scroll engine is battle-tested across shadow DOM, accordions, and heavily dynamic pages. ### How do I open TabX, and can I cancel anytime? Press Ctrl/Cmd + I to open the TabX side panel on any page, or click the extension icon. Billing is month-to-month or annual and you can cancel in one click from the billing portal — no lock-in. ## Links - Home: https://www.tabx.dev - Pricing: https://www.tabx.dev/#pricing - FAQ: https://www.tabx.dev/#faq - Privacy Policy: https://www.tabx.dev/pp (Markdown: https://www.tabx.dev/pp.md) - Terms of Service: https://www.tabx.dev/tos (Markdown: https://www.tabx.dev/tos.md) - Chrome Web Store: https://chromewebstore.google.com/detail/tabx/bdmeibkfombnjpgjpokdpkbbmfbnmafl
