## 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

## Qsafe (C9Lab)

Qsafe is one of the flagship products of C9Lab, a cybersecurity vendor focused on digital risk protection (DRP) and phishing simulation. Qsafe's job is external threat detection: it watches domains, mobile app stores, social media and dark web channels for signs that someone is impersonating your brand, then surfaces those threats with risk context instead of raw alerts. Typical findings include lookalike or typosquatted domains, phishing URLs, fake mobile apps, fraudulent listings and copycat social profiles.

Qsafe sits inside a wider C9Lab suite rather than standing alone. C9Pharos covers website security and uptime monitoring, C9Phish handles anti-phishing detection and employee phishing simulation training, and the free Business Risk Score (BRS) gives a quick external risk posture assessment. Together they cover brand protection, human risk, attack surface management and compliance reporting, and C9Lab offers an MSSP partner program so service providers can resell or white-label Qsafe and C9Phish from one multi-tenant console.

The platform is aimed at organisations rather than individuals: financial services, e-commerce, healthcare, technology, education and government are the highlighted verticals. Pricing is quote-based and requires contacting the vendor or booking a demo, which is typical for enterprise DRP tooling. Because detection, takedown and legal escalation are usually packaged together, buyers should ask about takedown SLAs and analyst involvement when evaluating it.

**Pricing & Plans:** Contact for pricing. C9Lab sells Qsafe through demos and quotes rather than published tiers, and offers an MSSP/white-label partner program for managed service providers.

- **Phishing and fake domain detection:** Monitors for phishing pages, lookalike and typosquatted domains, and other impersonation infrastructure aimed at your brand and customers.
- **Rogue app and social media monitoring:** Tracks app stores and social platforms for fake apps, impersonation profiles and fraudulent listings that abuse your identity.
- **Dark web monitoring:** Watches dark web channels for brand abuse, leaked credentials and mentions that signal upcoming fraud against your organisation.
- **Automated takedowns and incident response:** Provides takedown workflows for malicious content, backed by an analyst team for escalation and brand incident response.
- **Multi-tenant MSSP console:** Service providers can resell or white-label Qsafe alongside C9Phish from a single multi-tenant management console.

**Strengths:** Covers domains, apps, social media and dark web in one platform; Takedown workflows with analyst support, not just alerting; Part of a broader suite including website security and phishing simulation; Free Business Risk Score gives an instant external risk snapshot

**Limitations:** No published pricing, so evaluation requires a sales conversation; Enterprise-oriented: likely excessive and costly for small teams; Effectiveness depends heavily on takedown response times
