## 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

## Retime

Retime is scheduling software designed to replace the back-and-forth of arranging meetings. You define your availability, share a booking link or embed it in your site, and guests choose a slot that works — the event is then added to your calendar automatically. It is positioned for individuals who want a simple, free way to get booked, and for teams that need more control.

A free plan covers the essentials: Google Meet and Calendar support, 1-on-1 meetings, one scheduling link, one calendar connection per person, custom availability, cancellation and rescheduling, and desktop and mobile apps. Paid tiers unlock more scheduling links, multiple meeting types and teams, additional calendar connections, team calendar overlays, payments, and reporting.

Retime also folds light meeting management into scheduling. Teams can attach agendas, assign action items with due dates, and track tasks, so the tool supports the meeting follow-through as well as the booking. It integrates with a wide range of calendars and productivity apps and offers a 14-day trial of paid plans while keeping the free version available permanently.

**Pricing & Plans:** Retime has a free forever plan. Paid plans start at $10 per user/month (Basic), $16.67 (Pro), and $41.67 (Enterprise), with annual billing saving about 17% and a 14-day trial available.

- **Shareable booking links:** Define your availability once and share a booking page so guests pick a slot that fits your schedule.
- **Calendar synchronization:** Sync Google Calendar, Office365, Zoho, and more so your availability stays accurate and double-booking is avoided.
- **Payments for bookings:** Collect payments for paid bookings via Stripe and PayPal directly inside the scheduling flow.
- **Agenda and action items:** Plan meetings with agendas, action items, due dates, and a tasks section so follow-ups are not lost.
- **Team scheduling:** Overlay team calendars, create multiple meeting types, and manage several teams from one account.

**Strengths:** Generous free plan for individuals; Wide integration list including Google, Microsoft, Zoho, Stripe and PayPal; Built-in agendas and action items go beyond basic booking; 14-day trial of paid plans with a free version that never expires

**Limitations:** Advanced features like custom domains and payments require higher tiers; Calendar sync depth varies by which integrations you use; No major caveats — free tier is generous but capped at one link and one calendar connection
