## DeClassIFY

DeClassIFY installs as a browser extension and works on the PDFs you already download every day. Instead of opening each file to find out what it is, the extension reads the document and assigns it a category, turning a folder of mixed downloads into something you can triage at a glance. The pitch is simple: stop burning hours on files that were never useful to you.

The extension is intentionally narrow in scope. It does not try to be a full document manager, an editor or a cloud drive — it does one job, classification, and keeps the footprint small (under half a megabyte) so it stays out of the way of normal browsing. The listing states that the developer does not collect or sell user data.

Because it is distributed through the Chrome Web Store, installing and removing it takes a single click, and updates arrive automatically. It will suit researchers, students, analysts and office workers who collect large numbers of PDFs and need a fast first-pass filter.

**Pricing & Plans:** Free to install from the Chrome Web Store. The listing does not advertise a paid tier; any premium features, if they exist, are not described on the store page.

- **One-second PDF classification:** Reads a PDF and assigns it a document category immediately, so you can decide whether it deserves your attention.
- **Triage for mixed download folders:** Turns a pile of unsorted PDFs into labelled groups you can scan quickly instead of opening file by file.
- **Tiny footprint:** The extension is only a few hundred kilobytes, so it loads fast and does not slow browsing down.
- **Privacy-conscious design:** The developer declares that user data is not collected, sold or used for unrelated purposes.
- **One-click install and updates:** Installs straight from the Chrome Web Store and updates automatically, with no separate account required.

**Strengths:** Very fast classification that removes the manual step of opening every PDF; Small, unobtrusive extension that does not slow the browser down; Free to install and distributed through the official Chrome Web Store; Explicit statement that user data is not collected or sold

**Limitations:** Small user base at the time of writing, so community reviews are limited; Only classifies PDFs — it is not a reader, editor or file manager; No public pricing page describing premium tiers or higher limits

## Kagi Search

Kagi takes the familiar search box and rebuilds the incentives around it. Rather than showing ads or sponsored placements, it is funded entirely by subscriptions, which means results are ranked on relevance instead of who paid. Technically it aggregates several leading search engines, then re-ranks the combined pool and filters out spam and low-quality pages, so you get broad coverage without the clutter.

The control layer is what makes Kagi distinct. You can boost, lower, pin, or block any domain so results reflect your own judgment about trustworthy sources. Search Lenses focus a query on a category like forums, news, or academic material, bangs and snaps jump into or restrict to a specific site, and the interface itself is highly customizable, from which result sections appear to full CSS restyling.

Kagi has also grown into an ecosystem. Quick Answer and the Kagi Assistant generate responses grounded in search results, Kagi Translate handles translation, and Summarize condenses long pages. Beyond the browser, the company ships Orion Browser and related tools such as Kagi News, Maps, and Mail. Query privacy is a core promise: searches are not logged or retained after results are returned.

**Pricing & Plans:** Kagi is paid rather than ad-supported. You can run a limited number of free searches anonymously and get additional searches during a trial, after which subscription plans for individuals, families, teams, and libraries apply. Plans start at a low monthly rate, with API access and some tools billed separately. Check the pricing page for current figures.

- **Ad-free, user-funded results:** Subscriptions replace advertising, so there are no sponsored results, affiliate links, or data sales influencing what you see.
- **Boost, lower, block:** Rank any website up or down, pin favorites, or block domains entirely so your results match your own standards.
- **Quick Answer and Assistant:** Append a question mark to get an AI answer above the results, or chat with the Assistant for deeper tasks with sources included.
- **Search Lenses and bangs:** Restrict searches to categories like forums or news, or jump straight into a specific site's own search with shortcuts.
- **Privacy-first ecosystem:** Translate, Summarize, News, Maps, and the Orion Browser extend the same no-tracking, no-selling approach beyond search.

**Strengths:** Zero advertising and no tracking-based monetization of your searches; Unusually fine-grained control over ranking, sources, and interface; AI answers and summaries grounded in the search results with visible sources; A widening suite of privacy-first tools beyond the search box

**Limitations:** Requires a paid subscription for full use, unlike free ad-supported engines; Search coverage depends on the upstream engines it aggregates rather than its own index; Some ecosystem tools are newer or still rolling out compared with the core search
