Top 15 'Lecture-to-Notes' AI Tools to try for Students to Stop Rewatching Hours of Recordings - Goh Ling Yong
Let's be honest. You've been there. It’s 11 PM, a major exam is looming, and you're staring at a playlist of ten different two-hour lecture recordings. You vaguely remember the professor mentioning a crucial concept in Week 4, but scrubbing through hours of video to find that one golden nugget feels like a monumental task. The caffeine is wearing off, and the urge to just give up and re-watch the entire series is tempting, but who has that kind of time?
This cycle of record, re-watch, and regret is a classic part of the student experience, but it doesn't have to be. We're living in an incredible era of technological advancement, and Artificial Intelligence is no longer just a sci-fi concept; it's a practical tool that can revolutionize the way you study. Imagine turning that two-hour lecture into a concise summary, a searchable transcript, and a set of perfectly organized notes in just a few minutes. It sounds like magic, but it's very real.
Here at the Goh Ling Yong blog, we believe in leveraging technology to work smarter, not harder. That's why we've dived deep into the world of AI-powered academic tools to bring you the definitive list. These 'lecture-to-notes' platforms are designed to be your personal study assistant, saving you countless hours and helping you focus on what truly matters: understanding the material. Say goodbye to endless re-watching and hello to academic efficiency.
1. Otter.ai
Otter.ai is one of the pioneers in the AI transcription space and remains a top contender for students. Its core function is simple but powerful: it takes your audio or video file and generates a highly accurate, time-stamped transcript. What makes it great for lectures is its ability to distinguish between different speakers (useful for Q&A sessions or guest lecturers) and to identify keywords automatically, giving you a quick overview of the main topics.
The platform's interface is clean and user-friendly. You can upload a pre-recorded lecture file or even connect it to your Zoom account to transcribe live online classes. Once the transcript is ready, you can read along, highlight important sections, add comments, and even share the notes with your study group. The search function is a lifesaver, allowing you to instantly find that specific term or concept you were looking for without re-watching a thing.
- Pro Tip: Create a "Custom Vocabulary" list within Otter.ai for each of your courses. Add complex terminology, professor names, and specific acronyms. This will significantly improve the accuracy of your transcripts, as the AI will learn to recognize the unique language of your subject.
2. Glean
If there's one tool on this list built from the ground up for students, it's Glean. It's more than just a transcription service; it's a complete note-taking ecosystem. Glean records your lecture's audio and visual presentation (slides) and synchronizes them with the notes you type. Instead of frantically trying to write down every word, you can simply type a short tag or keyword. Later, clicking on that tag takes you directly to the exact moment in the recording when you wrote it.
The real AI magic comes in post-lecture. Glean transcribes the entire recording, making every word searchable. You can then use its AI features to generate a summary, identify key action items, and create structured notes from the raw transcript. It effectively turns a passive listening experience into an active, reviewable study resource. This is perfect for students who want to engage in class but also want a perfect record to fall back on.
- Pro Tip: Use Glean’s "post-it" and "heading" features during the lecture. When the professor says something like "This will be on the exam," hit the "Important" button. This creates visual cues in your notes, making your review sessions incredibly efficient.
3. Notion AI
Many students already live and breathe Notion for organizing their courses, assignments, and personal life. The introduction of Notion AI brings the power of 'lecture-to-notes' directly into that existing workflow. While Notion doesn't directly record lectures, its AI can process any text you put into it. You can use a separate tool (like Otter.ai) to get a transcript, then paste that entire transcript into a Notion page.
With a single click, Notion AI can summarize the key points, pull out action items (like "research the Foucault pendulum"), explain complex concepts in simpler terms, or even draft a set of flashcards based on the content. The seamless integration is the key selling point. You don't have to jump between different apps; your transcript, AI-generated summary, and personal notes can all coexist on the same page, linked to your course syllabus and assignment tracker.
- Pro Tip: After pasting a lecture transcript into Notion, use the AI command
/summarize. Then, highlight a specific complex paragraph and use the command/explain this. This two-step process gives you both a high-level overview and a deep dive into the parts you find most challenging.
4. Fireflies.ai
Originally designed for business meetings, Fireflies.ai has been eagerly adopted by students for online classes and virtual study groups. It acts as an AI assistant that can join your Zoom, Google Meet, or Microsoft Teams calls automatically. It records, transcribes, and analyzes the entire conversation, sending you a complete summary shortly after the session ends.
Its "Smart Search" feature is incredibly powerful. You can search not just for keywords but also for topics and themes discussed during the lecture. For example, you could search for "discussion about marketing ethics," and Fireflies would pull up all relevant segments. It also creates a "Soundbites" feature, allowing you to clip and share important audio snippets—perfect for sharing a professor's key explanation with a classmate.
- Pro Tip: Use Fireflies.ai for your virtual study group meetings. It will transcribe your entire discussion, and its AI can generate a list of "Action Items" to ensure everyone knows their responsibilities for the upcoming group project.
5. Fathom
Fathom is a fantastic and, most importantly, free tool for students who attend classes on Zoom. It acts as a live assistant during your call, sitting quietly in the background. With a single click, you can highlight a moment in the lecture you know is important. Fathom will instantly transcribe that snippet and use AI to summarize it for you.
After the class is over, Fathom provides a full, searchable recording and transcript. The best part is the automatically generated summary, which is broken down into a high-level overview and a more detailed, time-stamped list of topics discussed. You can click on any topic and jump directly to that point in the video. For students on a budget who primarily use Zoom, Fathom is an unbeatable option.
- Pro Tip: Before your Zoom class starts, open Fathom and look at the control panel. Customize the "highlight" buttons to reflect your needs, such as creating a button for "Exam Question Hint" or "Confusing Concept." This lets you categorize important moments in real-time.
6. Descript
Descript is a powerhouse tool that blurs the line between a transcription service and a full-fledged audio/video editor. If your courses involve a lot of multimedia content (e.g., film studies, communications, marketing), Descript is a game-changer. You can upload a lecture video, and it will generate a transcript so accurate that you can edit the video simply by editing the text. Delete a sentence in the transcript, and Descript automatically snips it from the video.
Its AI features are top-notch. The "Studio Sound" feature can remove background noise and echo from a poorly recorded lecture, making it much easier to listen to. Its "Summarizer" can condense a long-winded monologue into the key takeaways, and the "Find Good Clips" feature uses AI to identify the most engaging or important parts of the recording for you.
- Pro Tip: If you have to give a presentation, record yourself practicing in Descript. It will transcribe your speech, allowing you to easily spot and remove filler words like "um" and "ah" just by deleting them from the text.
7. tldv (Too Long; Didn't View)
Similar to Fathom, tldv is another excellent free tool that integrates with Google Meet and Zoom. It's designed to make re-watching a thing of the past. During a live lecture, you can add time-stamped notes and tag teammates (or study partners), which are then compiled into a neat summary.
The AI features shine after the meeting. tldv automatically creates "chapters" for the lecture based on the topics discussed, making it easy to navigate. Its AI can also generate summaries, pull out key highlights, and provide a full transcript. One of its standout features is the ability to create and share short video clips from the lecture recording—perfect for reviewing a complex explanation or sharing a specific point with a friend who missed the class.
- Pro Tip: Use the "Reels" feature in tldv to create a short highlight reel of the most important concepts from all your lectures before an exam. Watching a 10-minute supercut is far more efficient than re-watching 20 hours of content.
8. AudioPen
AudioPen has a beautifully simple premise: it turns messy, rambling voice notes into clear, structured text. While not a direct lecture recorder, it's an indispensable tool for processing your thoughts after class. Instead of trying to type out a perfect summary of what you just learned, you can simply open AudioPen and talk. Ramble on, repeat yourself, go off on tangents—it doesn't matter.
Once you're done, its AI cleans everything up. It removes filler words, corrects grammar, and rewrites your spoken thoughts into a well-structured summary. This is incredibly useful for solidifying your understanding of a topic. You can verbally "explain" a concept to AudioPen as if you were teaching it to someone else, and it will provide you with a perfect set of written notes on that topic.
- Pro Tip: After a complex lecture, take a 5-minute walk and use AudioPen to record your immediate thoughts and questions. The AI will organize them into a coherent list you can use to guide your studying or to ask for clarification in the next class.
9. Sonix
For students who need the highest level of accuracy, especially in technical fields or for multi-language content, Sonix is a premium choice. It boasts fast, incredibly accurate transcription with features like automated speaker labeling and precise time-stamping. Its in-browser editor makes it easy to review and polish the transcript.
Where Sonix truly stands out is its translation capabilities. It can transcribe and translate your lecture into over 38 languages. This is a massive advantage for international students or those studying a foreign language. The AI-powered summary and thematic analysis tools help you quickly grasp the core concepts of the lecture without getting bogged down in the details.
- Pro Tip: If you're an international student and your professor speaks quickly, use Sonix to get a transcript in the original language. Then, use the translation feature to generate a version in your native language. You can compare the two side-by-side to clarify difficult vocabulary and concepts.
10. Tactiq
Tactiq is a free Chrome extension that generates real-time transcripts for Google Meet and Zoom. What makes it unique is that the transcript appears in a small window right beside your video call, so you can follow along as the lecture happens. You can highlight key points with a single click as they are spoken, and Tactiq will save them for you.
The AI-powered magic happens after the call. Tactiq uses OpenAI's models to automatically generate a detailed summary, identify key questions asked during the session, and list action items. This is perfect for staying engaged during the lecture without having to worry about missing anything important.
- Pro Tip: Use Tactiq’s "Ask AI" feature on the live transcript. If the professor mentions a term you don't understand, you can ask the AI to define it for you in real-time, right within the Tactiq window, without disrupting the class.
11. Anthropic's Claude
Unlike specialized tools, Claude is a general-purpose AI chatbot, similar to ChatGPT, but with a key advantage for students: a massive context window. This means you can paste an incredibly long lecture transcript—often the entire thing—into a single prompt and ask Claude to work with it. Other models might require you to break the text into smaller chunks.
Once you've pasted your transcript, the possibilities are endless. You can ask Claude to "Create a detailed study guide from this lecture," "Identify the three most important arguments the professor made," "Generate 10 potential multiple-choice questions based on this content," or "Explain the section on quantum mechanics as if I were a high school student." It's a versatile and powerful study partner.
- Pro Tip: After getting a summary from Claude, follow up with this prompt: "Now, act as a friendly tutor. Ask me questions about this lecture to see if I understood the key concepts." This turns passive review into active recall practice.
12. Microsoft Copilot
For students embedded in the Microsoft ecosystem (using Word, OneNote, and Teams), Copilot is becoming an indispensable AI assistant. If your university uses Microsoft Teams for online classes, Copilot can provide intelligent recaps, transcribing the meeting and generating AI-powered notes and action items automatically.
The real power lies in its integration with other apps. You can take a lecture transcript and bring it into Microsoft Word. From there, you can ask Copilot to "Summarize this document," "Rewrite this section for clarity," or "Create a table comparing the theories mentioned." In OneNote, it can help you organize your notes and generate review questions, keeping all your study materials in one place.
- Pro Tip: Use the dictate/transcribe feature in Microsoft Word to capture audio, then immediately use Copilot within the same document to summarize it and generate a list of key terms. This creates a seamless workflow from raw audio to structured notes.
13. Read.ai
Read.ai is another meeting-focused tool that offers deep, analytical insights perfect for detail-oriented students. It joins your online classes and provides a transcript, recording, and an AI-generated summary. However, it goes a step further than most.
Read.ai provides an "Impact Score" for the lecture, highlighting the most engaging moments. It also generates a topic-based outline with timestamps and summaries for each section. One of its best features is the "Key Questions" report, which automatically identifies every question asked during the lecture (by both the professor and students) and lists the answers if they were provided. This is an incredible resource for exam preparation.
- Pro Tip: Review the "Key Questions" report from Read.ai before an exam. It’s a goldmine for understanding what the professor and your peers found most important or confusing, which often aligns with testable material.
14. Laxis
Laxis is designed for people who want structured, intelligent notes. It transcribes your lectures and then uses AI to help you extract insights based on pre-set or custom templates. For example, you could have a template for "Problem/Solution," "Pros/Cons," or "Key Definitions."
During or after the lecture, you can highlight parts of the transcript and tag them according to your template. Laxis then automatically organizes these highlights into a neatly structured document. Its AI can also suggest summaries and insights based on the content, making it easy to convert a long, unstructured conversation into a practical study guide.
- Pro Tip: Before the semester starts, create a custom Laxis template for each of your courses based on the syllabus. Include categories like "Main Theory," "Historical Context," "Key Figures," and "Case Study Example." This will help you capture relevant information in a structured way from day one.
15. Supernormal
Supernormal brings speed and automation to the forefront. It's particularly great for students who need notes delivered instantly. It can transcribe your online lectures in real-time and, using AI, write detailed notes automatically. You don't have to lift a finger.
The platform offers several pre-built note templates, and you can create your own. For instance, you could have a "Cornell Notes" template, and Supernormal will attempt to structure the AI-generated notes into cues, notes, and a summary section. The focus is on a fully automated workflow that delivers polished notes to your inbox moments after your class ends.
- Pro Tip: Connect Supernormal to your Google Drive or Notion. Set up an automation so that your AI-generated lecture notes are automatically saved into the correct course folder, keeping you perfectly organized with zero extra effort.
