Is my browsing history really private?

Yes. Histiq stores everything in your browser's local IndexedDB. Embeddings are generated on your device with a small in-browser model (Xenova/MiniLM). Nothing is sent to any server. You can verify by inspecting the extension's network requests — there are none for your history.

How does the 14-day trial work?

The trial runs entirely inside the extension and starts on install — no signup, no card, no account. All features are unlocked for 14 days from day one. After that, pick a plan (Monthly, Annual, or Lifetime) to keep using semantic search.

What happens after my trial ends?

Your indexed history is frozen — not deleted. You won't be able to search until you subscribe, but all your data is preserved locally. Subscribe anytime and everything is instantly available again. If you don't subscribe within 30 days of trial end, data is cleared.

Does Histiq work on Firefox and Edge?

Yes. Histiq is available for Chrome, Firefox, and Edge. All features — semantic search, local indexing, PDF support, privacy filters — work identically across all three browsers.

How does AI semantic search work without sending data anywhere?

When you visit a page, Histiq runs a small embedding model (Xenova/MiniLM, ~25MB) directly in your browser to convert the page content into a 384-dimensional vector. When you search, your query is converted the same way, and the closest matches are returned via cosine similarity — all on your device. No external API, no model server, no cloud.

Does Histiq index PDFs?

Yes. When you open a PDF in your browser, Histiq automatically detects it, extracts the text layer using PDF.js, and indexes it in chunks — just like a web page. You can search across research papers, contracts, documentation, and any text-based PDF by meaning, not filename. PDFs up to 50 MB are supported.

Will my browser slow down?

No. Indexing happens in a background service worker with idle-priority scheduling. Embedding generation is throttled to use unused CPU cycles. On a modern laptop, you won't notice Histiq is running.

Can I cancel my subscription anytime?

Yes. Cancel anytime from your billing portal — no questions asked. Your local indexed data stays on your device regardless of subscription status.

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

Semantic search for every page and PDF you read.

🧠

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

📄

Searches your PDFs, not just pages

Open any PDF in the browser and Histiq extracts and indexes its text automatically. Find a research paper, a contract, or a report by what it said, not by its filename. Most history tools never touch your PDFs.

Up to 50 MB

🤖
