Beste KI-Lern-Apps 2026: 8 Tools, um Vorlesungen in Notizen umzuwandeln

1. Yaps: Talk Your Lecture Notes, Keep Them Private

Yaps is a voice-first, offline-first study app for Android, Windows, and macOS. It is built around the loop every student actually runs: capture the idea by talking, tidy the words automatically, file the result where you can search it, and hear it read back when you revise. Every one of those steps happens on your own device, so your recordings and notes never leave the machine and no account is needed to start.

That is the difference worth understanding. Speaking is roughly three times faster than typing, so the fastest way to get a lecture out of your head is to say it. Yaps makes talking the input method, then does the cleanup and filing you would otherwise do by hand at 11pm.

Study notes are only useful if you can find them again. Yaps keeps yours as searchable text on your own device, not in someone else's cloud.

Yaps for students

Talk your notes with the Yaps hotkey

Press the Yaps hotkey, talk, and clean text appears wherever your cursor is: your notes app, an email, a study doc, a browser, or a chat with a study group. Dictation runs through Yaps's on-device speech pipeline, so it works on a train with no signal and in a library with locked-down Wi-Fi.

It is multilingual. Yaps understands about 25 spoken languages and detects the language from your voice automatically, which matters if your lectures are in one language and your notes are in another. You do not switch a setting between a French seminar and an English tutorial. You just talk, and each lands as text.

Because dictation works across every app on the phone or laptop, it is not a "voice note mode" trapped inside one screen. It is the keyboard you already have, running about three times faster. See dictation for students for the full student setup.

On-device cleanup turns a brain-dump into tidy text

Spoken language is messy. You repeat yourself, you say "um", you start a sentence, stop, and restart it. Yaps cleans that up on your device as it writes: it removes filler words and false starts, fixes punctuation and capitalisation, and formats lists and numbers so a spoken "first, second, third" becomes a real list.

The outcome is the part that saves your evening. You ramble a summary of the lecture on the walk home, and what lands in your notes reads like something you wrote carefully, not a raw transcript you still have to edit.

A private, searchable vault

Everything you capture lands in Yaps voice notes: a private vault stored on your device. Search is local and instant, so typing "mitochondria" or "case law tort" surfaces every note that mentions it without a round trip to a server.

Notes are not just plain text. You can keep them as plain notes, checklists, or kanban boards, which suits a reading list or a revision plan as well as a lecture recap. When you need the notes elsewhere, you export to Markdown or plain text, both of which open in any editor with no lock-in.

If you study on two devices, vault note syncing keeps your phone and laptop in step. It is a premium feature that pairs the two over your local network or an encrypted peer-to-peer link with a QR code, so notes captured in the lecture hall are on your laptop by the time you sit down to write them up.

Turn a lecture you recorded into study notes, in four steps

If you already recorded a lecture on your phone or laptop, the Yaps Studio editor turns that audio file into text offline. Import the recording, let Yaps transcribe it on your machine, then trim and clean the result. You can export subtitles as an SRT file if you want to rewatch with captions, or send the transcript straight to your vault.

1. Open Studio and import the lecture audio file you recorded on your phone or laptop.
2. Let Yaps transcribe it offline. The local speech pipeline turns the audio into text on your machine, with no upload.
3. Clean and cut. Trim the dead air, fix any names, and let on-device cleanup remove the filler words.
4. Save it to your vault or export. Send the transcript to your searchable notes, or export subtitles as an SRT file for rewatching.

Listen back to revise

Revision is where read-aloud earns its place. Yaps reads your notes back to you with 18 voices on desktop and 2 on mobile, so you can revise on a walk or a bus instead of staring at the page. Trigger it with Option and Fn on desktop, or pick "Read aloud with Yaps" from selected text on Android. Hearing a definition in a different voice is a genuinely effective way to catch the gaps rereading hides.

Where Yaps is honest about its limits

Three limits, stated plainly. First, Yaps does not send a bot into a live lecture to caption it as the professor speaks. For a recording you already have, Studio transcribes the file offline, and if you need live captions during the class itself, Otter is the right tool below. Second, the read-aloud voices are English speakers in practice, so if you need your notes read out in many languages, a multilingual cloud reader is the better fit for that one job. Third, the iPhone and iPad app is coming soon, so on iOS it is not available yet. Android, Windows, and macOS all ship today.

Pricing and platforms

Yaps runs on Android, Windows, and macOS, with a live Chrome "Save to Yaps" extension for clipping web pages into your vault. There is no free tier. You download it, start a 7-day free trial, then subscribe: Pro is $15 a month and Max is $25 a month. An account is required only for billing, not for the core capture, cleanup, and search that run on your device.

For the wider student workflow, voice tools for student productivity and the best dictation software for students go deeper on setup, accuracy, and habits.

2. NotebookLM

The strongest fallback when your problem is not capture but comprehension across a stack of sources. You upload your readings, slides, and a lecture transcript, and Google's NotebookLM answers questions grounded in exactly those documents, with citations pointing back to the passage it used. Its Audio Overview turns a source set into a spoken summary you can listen to.

NotebookLM is excellent for "I have ten papers and a syllabus and I need to make sense of them by Friday". It is not a daily capture tool, it runs in the cloud, and it needs an internet connection. Use it next to your Yaps vault, not instead of it: capture and store in Yaps, then point NotebookLM at the exports when you need to interrogate a pile of readings.

Free, with a paid Plus tier for higher limits.

3. Notion AI

The default for students who already run their whole degree inside Notion pages and databases. Notion AI summarises pages, drafts text, and answers questions about your workspace, which is handy when your notes, reading lists, and project trackers already live there.

The trade is where the data lives and how it is captured. Notion stores your notes in its cloud in a proprietary format, offline support is partial, and there is no real voice capture beyond your operating system's dictation. If you want notes as files you own, captured by talking, Yaps is the better fit. If you want a shared team workspace for a group project, Notion is the stronger pick.

Around $10 per user per month for the plan that bundles AI.

4. Obsidian

The pick for students building a broad, linked knowledge base they intend to keep for years. Obsidian is a plain-markdown editor stored on your own disk, with backlinks, a graph view, and a large community plugin ecosystem. You can wire in local AI and semantic search if you enjoy configuring tools.

The catch is that voice capture, cleanup, and AI are all separate setup decisions rather than shipped features, and mobile dictation is weak. If you want the same markdown-you-own promise with voice built in, Yaps exports to Markdown too and can sit alongside a vault like this. For the pure typed-PKM job, Obsidian is the deeper tool. See our take on building an AI second brain for how voice capture and a vault fit together.

Free for personal use. Sync is a paid add-on.

5. Otter

The right tool for live lecture captions. Otter listens while the class is happening and produces a running transcript in real time, which is genuinely useful if a professor talks fast or you have an access need for live text. It runs in the cloud and integrates with common meeting tools.

This is the one job Yaps does not do: Yaps has no live lecture bot. The trade with Otter is privacy, because your audio goes to its servers and there is no on-device mode. If live captions during the lecture are the priority, Otter wins. If you want the recording turned into private notes afterward, Yaps Studio does that offline.

Free tier with paid plans for more minutes.

6. Anki

The gold standard for spaced repetition, the technique of reviewing a fact at widening intervals so it sticks. Anki schedules your flashcards so you see each one just before you would forget it, and its scheduling is the most respected in the category. Medical and language students in particular swear by it.

Anki does not capture lectures and does not write your notes for you. It is the revision engine, not the capture tool. The natural pairing is to capture and organise in Yaps, then move the definitions worth memorising into Anki cards. Yaps does not ship spaced repetition, so for pure flashcard drilling, Anki is the fallback to reach for.

Free on desktop and Android. The iPhone app is a one-time paid purchase.

7. Quizlet

The friendlier flashcard app, and the one with the biggest shared library. Quizlet is fast to make a set in, has study games that keep you going, and now layers AI study modes on top. For quick memorisation of vocabulary, terms, and definitions, it is hard to beat on ease of use.

Like Anki, it is a drilling tool, not a capture or notes tool, and more of it lives in the cloud. If you want the review step handled with the least friction and a library of ready-made sets, Quizlet is the pick. For getting the lecture into notes in the first place, that is Yaps.

Free tier with a paid plan that removes ads and adds features.

8. GoodNotes

The choice for students who think best with a pen. GoodNotes turns an iPad or Android tablet into a paper-like notebook, with handwriting that stays searchable, PDF markup for annotating readings, and AI study features layered on. If you diagram, sketch equations, or annotate slides by hand, nothing on this list beats it.

The trade is that it is a handwriting-first, tablet-first tool. There is no cross-app voice dictation, and the notes live in its own format. If your capture is spoken rather than drawn, Yaps is the better loop. If it is drawn rather than spoken, GoodNotes is the honest pick.

Paid, with a free tier limited to a few notebooks.

Four questions decide which study app owns your week: does it keep your work private and offline, can you capture by voice, can you search your own notes, and can it read them back for revision. Here is how the top picks answer.

The pattern is clear. Several tools do one column well. Yaps is the one that does all four in a single app, and does them without sending your work to a server.

Which step of the loop is your bottleneck? That question settles it faster than any feature list.

If you cannot get lectures out of your head fast enough, or you value privacy and offline use, start with Yaps: it captures by voice, cleans the text, files it, and reads it back. If your problem is making sense of a stack of readings, add NotebookLM. If you need live captions while the professor is still talking, use Otter. If your notes are already written and you just need them to stick, drill them in Anki or Quizlet. If you take notes with a pen, use GoodNotes.

Most students need the capture-and-recall loop first, with one specialist tool bolted on for a single job. That is why Yaps is the default here.

What is the best AI study app in 2026?

Yaps is the best AI study app for most students in 2026. It runs the full study loop on your own device: dictate notes by voice in any app, clean the text automatically, keep it in a private searchable vault, and listen back to revise. It works offline, needs no account for the core features, and runs on Android, Windows, and macOS. NotebookLM, Otter, Anki, and GoodNotes are strong fallbacks for source research, live captions, flashcards, and handwriting respectively.

Are there free AI study apps?

Yes, Anki and Quizlet both have free tiers for flashcards, and NotebookLM and Otter offer limited free plans. Yaps does not have a free tier: it is a paid app with a 7-day free trial, after which Pro is $15 a month and Max is $25 a month. The difference is scope. The flashcard apps drill facts you already wrote, while Yaps handles the capture, cleanup, search, and read-aloud that come before revision.

Can AI turn my lecture recording into notes?

Yes. If you recorded a lecture on your phone or laptop, the Yaps Studio editor imports that audio file and transcribes it into text offline, on your own machine. You can then clean it up, save it to your searchable vault, or export subtitles as an SRT file to rewatch with captions. The audio never leaves your device during transcription.

Which study app works offline?

Yaps works offline for its core features, including voice dictation, text cleanup, note search, and transcribing a recording in Studio. This matters on a train, in a lecture hall with weak Wi-Fi, or anywhere you would rather not depend on a signal. NotebookLM, Notion AI, and Otter all require an internet connection because they run in the cloud.

What is the most private study app for students?

Yaps is the most private option here. Your voice is processed on your device, your recordings are not uploaded, and your notes are stored locally as text you own, with no telemetry on your voice. Anki is also local but does not capture or write notes for you. The cloud tools on this list, including NotebookLM, Notion AI, and Otter, send your content to their servers to work.

How much does Yaps cost?

Yaps has no free tier. You download it, start a 7-day free trial, then subscribe: Pro is $15 a month and Max is $25 a month. An account is only needed for billing, so the on-device capture, cleanup, and search all run without one during the trial. There is no separate charge for the offline dictation that most students use every day.

Does Yaps work on iPhone or iPad?

Not yet. The iPhone and iPad app is coming soon, so on iOS Yaps is not available today. It ships now on Android, Windows, and macOS, plus a Chrome extension for saving web pages into your vault. If you need an iPhone study app right now, capture on a Windows or Mac laptop with Yaps and revisit this when the iOS app arrives.

Can Yaps transcribe a live lecture as it happens?

No. Yaps does not send a bot into a live class to caption the professor as they speak. For live captions during the lecture, Otter is the right tool, because it listens and transcribes in real time. For a recording you already made, Yaps Studio transcribes the audio file offline afterward and turns it into private notes.

Is Yaps or NotebookLM better for studying?

They solve different steps, so many students use both. Yaps is better for capturing lectures by voice, cleaning the text, and keeping searchable private notes on your device. NotebookLM is better when you have a stack of readings and want to ask questions grounded in those specific documents, with citations. Capture and store in Yaps, then point NotebookLM at the exports when you need to interrogate the sources.

Can I make flashcards with Yaps?

Not directly. Yaps does not ship spaced repetition or a flashcard system, so for drilling facts, Anki and Quizlet are the fallbacks. The natural workflow is to capture and organise your notes in Yaps, then turn the key definitions into cards in Anki or Quizlet. Yaps owns the capture and recall steps, and the flashcard apps own the memorisation step.

Can Yaps read my study notes aloud so I can revise by listening?

Yes. Yaps reads your notes back with 18 voices on desktop and 2 on mobile, which is a strong way to revise on a walk or commute. Trigger it with Option and Fn on desktop, or choose "Read aloud with Yaps" from selected text on Android. The shipped voices are English speakers in practice, so if you need revision audio in many languages, a multilingual cloud reader fits that specific need better.

What languages does Yaps dictation support?

Yaps dictation understands about 25 spoken languages and detects the language automatically from your voice, so you do not switch a setting between classes taught in different languages. This is useful if your lectures are in one language and you take notes in another. The read-aloud voices, by contrast, are English speakers in practice.

Does Yaps need an internet connection or an account?

No, not for the core study features. Dictation, text cleanup, note search, and transcribing a recording in Studio all run on your device with no connection and no account. You only need an account for billing, and premium vault syncing between your phone and laptop pairs the two devices directly over your local network or an encrypted link rather than through a public cloud.

Is Otter or Yaps better for students?

It depends on when you need the text. Otter is better for live captions while the lecture is happening, because it transcribes in real time in the cloud. Yaps is better for everything around that: capturing your own recap by voice, cleaning it, storing it privately, transcribing a recording afterward, and reading notes back to revise. For a private, offline study loop, Yaps is the default, with Otter added when live captions are the priority.
