## FasTube

FasTube addresses a very common irritation: you know a video or page contains the answer you need, but finding it means dragging a scrubber back and forth for several minutes. The extension flips that workflow. You highlight a phrase or question, launch the side panel with a click or the Ctrl/Cmd + M shortcut, and FasTube returns a set of timestamps pointing to the moments where that topic is actually discussed.

The tool is intentionally small and stays out of the way. It installs as a Chrome side panel, so it can be summoned over YouTube, lecture recordings, podcasts, documentation pages and PDFs without changing the layout of what you are reading. The developer claims results typically arrive within one to two seconds, and the companion ChatGPT integration lets you highlight a chatbot response and jump to the timestamped source material behind it.

FasTube is distributed through the Chrome Web Store as a free extension from independent developer Royce Braden Arockiasamy. At the time of this review the listing shows version 1.1, an update from April 2024, a 5.0 rating from a small handful of reviews and roughly a couple of hundred users. It declares that it does not collect or sell user data, which keeps the privacy footprint modest for a browser add-on of this kind.

**Pricing & Plans:** FasTube is offered as a free Chrome extension. There is no paid tier or subscription advertised on the extension listing; optional usage limits may apply to the AI features depending on the developer's backend.

- **AI-generated video timestamps:** Highlight a question or keyword and FasTube returns the moments inside a video where that topic is covered, so you can skip straight to the answer.
- **One-click side panel:** Launches from the toolbar or with the Ctrl/Cmd + M keyboard shortcut, appearing as a Chrome side panel that never covers the content you are watching.
- **Works beyond YouTube:** Handles videos on other platforms as well as articles and PDFs, so the same timestamp workflow applies almost anywhere you read or watch.
- **ChatGPT visual integration:** Connect chatbot replies to the underlying source material so an answer written by ChatGPT can be located and verified visually in the original video or page.
- **Fast results, light footprint:** The developer advertises results in one to two seconds and the extension package ships at roughly 25 KB, so it adds almost nothing to browser load.

**Strengths:** Removes the slowest part of video research by jumping directly to relevant timestamps; Very small install footprint with fast advertised response times; Works across general websites, PDFs and ChatGPT responses rather than only one platform; Clear privacy stance: the developer declares no collection or sale of user data

**Limitations:** Small user base and few reviews, so reliability across many site types is not widely proven; Last listed update is from April 2024, which raises questions about ongoing maintenance; Requires the Chrome browser and an active internet connection for the AI features to work

## 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.

**Pricing & Plans:** Knowt's core features are free: unlimited learn mode, free practice tests, flashcard creation, imports, and AI study tools with reasonable usage limits. Optional paid upgrades (Plus/Unlimited-style tiers) unlock higher AI generation limits and premium features. No credit card is required to start studying.

- **AI PDF Summarizer and Flashcards:** Upload up to 30 files and Kai instantly produces notes, flashcards, summaries, and practice resources from them.
- **Import and Lecture Recording:** Convert Quizlet, Kahoot, Wayground, and YouTube content, or record live lectures to generate notes and study sets.
- **Exam Predictor and Planner:** Upload class files to get a study plan and exam prediction that highlights what your professor emphasizes most.
- **Voice Tutoring and Podcasts:** Kai quizzes you by voice and can turn any note or flashcard into a podcast for study on the go.
- **Study Modes and Exam Prep:** Free learn mode, matching games, spaced repetition, and practice test rooms cover AP, ACT, and SAT prep.

**Strengths:** Free core with unlimited learn mode and practice tests; One-click Quizlet import preserves formatting and images; AI turns PDFs, slides, and lectures into study materials; Strong AP, SAT, and ACT prep resources plus a Chrome extension

**Limitations:** Some AI generation limits encourage upgrading to paid plans; Advanced study plans rely on accurate file uploads; Best experience requires creating an account to save materials
