## Horus

Horus is a free Chrome extension designed to act as a reading and research companion while you browse. Its core function is summarization: instead of reading an entire article, you get a condensed set of key points, which is useful for fast readers or anyone who wants the gist before committing time. Because it runs as a browser extension, it integrates directly into your existing browsing flow.

Beyond summaries, Horus answers questions about whatever page you are on. You can highlight a topic and ask for clarification, and the assistant pulls from the page and related web content to respond. This makes it handy for research, study, or casual curiosity without opening a search engine in a new tab. It also covers two common friction points in reading: translation and rewriting, letting you convert page text into another language or rephrase dense paragraphs into simpler wording.

A notable extra is PDF chat. Large documents such as reports and textbooks can be opened and queried directly, so you can extract the information you need without scrolling endlessly. Horus is publisher-distributed through the Chrome Web Store and shows a modest user base, and it is free to install, which makes it easy to evaluate if its approach fits your workflow.

**Pricing & Plans:** Horus is a free browser extension offered at no cost. You install it from the Chrome Web Store and use its summarization, Q&A, translation, rewriting, and PDF chat features without a paid plan.

- **Instant page summaries:** Instantly condense a long web page into a precise summary so you can grasp the main points without reading everything.
- **In-page question answering:** Ask a specific question and get an answer drawn from the current page and related web information without leaving the tab.
- **Text translation:** Translate page text into your preferred language for multilingual browsing and language study.
- **Paragraph rewriting:** Rewrite or paraphrase selected paragraphs into simpler, clearer wording to make complex sentences easier to follow.
- **PDF chat:** Open a PDF inside the extension and chat with it, so large documents, textbooks, and reports become easier to digest.

**Strengths:** Free to install and use, with no subscription barrier; Works inside the browser so you never leave the page you are reading; Combines summaries, Q&A, translation, rewriting, and PDF chat in one tool; PDF chat makes long documents and textbooks easier to digest

**Limitations:** Small user base and low install count may limit community support; Last updated in 2024, so it may not include the newest model capabilities; Listed with no ratings yet, so quality is hard to gauge before installing; Relies on the developer's backend service, so availability depends on the publisher

## Knowt

Knowt is a study platform built around flashcards and AI study tools, and it markets itself as the leading free Quizlet alternative. Its pitch is consolidation: rather than juggling several apps, students upload their class materials once and get flashcards, notes, summaries, and practice tests generated in one place. Importing existing Quizlet sets takes a couple of clicks, including images and formatting.

The AI layer is powered by Kai, an assistant that works across PDFs, slides, images, videos, and live lecture recordings. Uploading files produces notes, flashcards, and quizzes automatically, and Kai can also answer questions about your materials and explain why a practice answer was wrong. An Exam Predictor and Planner builds a study schedule from uploaded course files, while Voice Tutoring & Podcasts let students be quizzed aloud or turn notes into audio for studying on the go.

Knowt is free to use for core studying, with unlimited learn mode and free practice tests. It is widely adopted in education, with millions of students and teachers using it and a strong presence in AP exam preparation, alongside SAT and ACT resources and a Chrome extension for on-screen study.
