## 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

## Letterly

Letterly is built for people who would rather talk than type. You open the app and record, or speak directly into Gmail, Slack or Notion through the system dictation layer, and Letterly returns polished text matched to the format you need — a message, an email, a note, a journal entry or a social post. Rewrites are handled by AI: pick a ready-made style such as a formal email or a concise meeting recap, or describe your own format and reuse it later.

Longer recordings get more structure. Letterly handles talks up to about 90 minutes and can split a meeting or lecture transcript by speaker, then produce a summary alongside the full text. Recordings and rewrites are unlimited on the platform, audio and video files can be uploaded for transcription from any device, and notes can be searched by keyword or organized with tags. Offline recording means ideas captured without a connection still arrive in your library.

Letterly is available as a native app for iOS, Android, macOS and Windows plus a web client, with sync across devices. It connects outward too: translations into 90+ languages, text replacements for frequently used phrases, custom vocabularies, Zapier and webhook integrations, Apple Watch recording, and an MCP server that lets assistants like Claude or ChatGPT read and manage your notes. The company states that user content is not used to train AI models.

**Pricing & Plans:** Letterly is free to start with a freemium model. The free tier covers everyday dictation, while paid plans unlock higher usage limits and advanced features; pricing is shown in-app and on the website.

- **Dictate into any app:** Speak inside Gmail, Slack, Notion or any other text field and have clean text appear where you were typing, instead of switching apps.
- **AI rewrites and styles:** Convert raw speech into notes, emails, posts or meeting summaries using ready-made styles or your own saved formats.
- **Meeting and lecture transcripts:** Record up to around 90 minutes, get a transcript split by speaker, and generate a summary alongside the full text.
- **90+ languages with auto-detect:** Language detection happens automatically as you speak, and you can switch mid-sentence without changing settings.
- **Cross-device sync and integrations:** Native apps for iOS, Android, macOS and Windows plus web, with offline recording, translation, Zapier and webhooks, and an MCP connection for AI assistants.

**Strengths:** Works as both a dedicated app and a dictation layer inside tools you already use; Handles long recordings and separates speakers, which basic dictation tools often cannot; 90+ languages with automatic detection and mid-sentence switching; Available on iOS, Android, macOS, Windows and web with sync, plus offline recording

**Limitations:** Voice-first workflow is less convenient in shared or noisy environments; Free tier has usage limits, so heavy dictation requires a paid plan; Accuracy still depends on microphone quality and background noise
