Sound familiar?

Browser history is broken — and it costs you every day.

You already read it. You already spent the time. Histiq makes sure that work never gets lost.

Your problem

You've got 40 tabs open right now. You're scared to close any of them, because closing a tab means losing it for good.

Histiq solves it

Close all of them. Every page is already indexed on your device. Pull any one back just by describing it, in seconds. Your tabs stop being your memory.

Your problem

You solved this exact thing last month. Now you're re-googling it, opening five wrong links to find the one you already read.

Histiq solves it

You research something once. Everything you've read stays instantly searchable, so you never hunt for the same answer twice.

Your problem

You know you read it. You just don't remember the title, the site, or a single exact word from it.

Histiq solves it

Describe it the way you actually remember it. A vague phrase is enough — Histiq searches by meaning, not by exact keywords.

Your problem

That research paper you read three weeks ago is now a file called 2401.07037.pdf. Good luck finding it.

Histiq solves it

Histiq reads and indexes PDF contents automatically. Find any paper, contract, or report by what it actually says, not its filename.

Features

Browser history search, finally done right.

🧠

Exact words, or just the meaning

Remember the exact phrase? You get an instant match. Don't? Histiq searches by meaning instead — "article about startup fundraising from YC" finds it even when you can't recall the title, the URL, or the exact words on the page.

🔒

Fully local & private

Your history never leaves your device. Embeddings and search run entirely in-browser — verified in DevTools.

Zero outbound requests

🤖

Indexes the whole page

Histiq silently indexes the full text of every page you visit — even collapsed FAQs, tabs, and "read more" sections most tools skip. No manual work, it just runs in the background.

Lightning-fast results

Search through thousands of pages in under 50ms. Local vector index, zero network round-trips.

🌐

Chrome & Edge

Works on both, from a single install. Your full reading history in one searchable place.

📄

PDF text-layer indexing

Open any PDF in the browser — Histiq extracts and indexes its text layer automatically. Search research papers, contracts, and reports by meaning, not filename.

Privacy controls you actually own

Exclude domains, mask sensitive URLs, set retention windows. Everything stays on your device — auditable in DevTools anytime.
