Choose an AI note-taking app by the work you want to finish. Otter focuses on conversations and meeting records. Word and OneNote Transcribe help you correct speech as text. Gemini Notebook helps you question a collection of sources. Notion AI works within an ongoing workspace. Goodnotes connects notes and audio, while Notibo turns recordings and documents into editable study material.
This comparison uses official documentation checked on 11 October 2026. It does not rank transcription accuracy: that requires a comparable recording test, including your language and subject vocabulary.
Compare the output before the headline feature
| Tool | Useful starting point | Important limit to check |
|---|---|---|
| Otter | A conversation you need to search and summarise | Recording length, imports and supported language |
| Word or OneNote Transcribe | Audio you need to correct and quote | Account, platform and upload allowance |
| Gemini Notebook | Several readings or transcripts to question together | Source imports, citations and compute allowance |
| Notion AI | Notes, tasks and shared course work already in Notion | Workspace entitlement, usage and member cost |
| Goodnotes | Handwritten notes alongside audio | Device, transcription mode and export format |
| Notibo | A permitted lecture or document to turn into study notes | Remaining minutes, upload size and checking against the original |
A transcript and a set of notes serve different purposes. Use the transcript to recover the wording; use your notes to organise an explanation, example or question. Generated summaries can omit conditions, so compare the two when a claim matters.
The Dunlosky review rated practice testing and distributed practice highly across the evidence it assessed. That supports making time to retrieve and revisit knowledge. It does not establish that one note app produces better learning than another, or that storing ordinary text is ineffective.
Otter: check the length of one conversation
Otter's pricing page lists Basic at 300 minutes monthly, with a 30-minute conversation cap and three lifetime file imports. Pro has 1,200 monthly minutes, a 90-minute conversation cap and ten monthly imports, at US$16.99 monthly or US$8.33 per month billed yearly.
Otter records in its own apps and can join supported online meetings. It produces transcripts and summaries, so describing it as merely a raw transcript would miss part of the product. Its six listed languages are English, Spanish, French, German, Japanese and Chinese; the newer German and Chinese options are marked beta.
A 50-minute class exceeds Basic's single-conversation limit. A two-hour class exceeds Pro's. Compare those constraints with your timetable before counting total monthly minutes. See Otter alternatives if they rule it out.
Word and OneNote: useful when checking the wording matters
Microsoft's Transcribe guide describes speaker-labelled text, correction and navigation back to audio. It accepts WAV, MP4, M4A and MP3 uploads. Microsoft 365 includes 300 uploaded minutes monthly, with 30,000 for a qualifying Copilot licence.
Confirm eligibility first. OneNote Transcribe requires Microsoft 365 on Windows. Word's Windows feature is scoped to commercial tenants; its web workflow uses Edge or Chrome. University access to some Office applications does not establish that every speech feature is available.
Audio is saved in your OneDrive. Sharing the document does not automatically settle access to that audio. The OneNote versus Word guide compares ongoing course pages with finished documents and explains export considerations.
Gemini Notebook: useful across selected sources
NotebookLM is now Gemini Notebook. It transcribes uploaded audio on import and uses the resulting text as a source. Google's import guide lists a 200 MB file ceiling and up to 500,000 words per source. A compressed lecture may fit where a large WAV does not.
Google announced a mobile recorder in September 2026. Check the app before class. On a computer, the documented source workflow begins with imports rather than direct recording.
Its flashcards and quizzes support difficulty settings and missed-card practice. Google does not document a spaced-review calendar. Its current usage limits use compute allowances with five-hour refreshes and a weekly ceiling, so older fixed daily-chat figures are misleading.
For a reading assignment, ask one checkable question and inspect the cited passages. Source chat and experimental web-capable chat have different boundaries. The lecture workflow explains how to keep that distinction clear.
Notion AI: useful inside work you already maintain
Notion is a workspace for pages, databases and collaboration. Its AI guide includes drafting, workspace context, connected sources and AI Meeting Notes. It is not limited to text you type manually.
Free and Plus have limited trial AI responses; ongoing Business and Enterprise use has allowances, with premium credits available when enabled. The pricing page distinguishes members from guests, which matters when budgeting for a group.
Eligible students can receive an individual Education Plan, but that should not be confused with unlimited AI. If the free workspace already solves missed deadlines, try it first. If your group repeatedly turns meetings into assigned actions, test the AI feature against those actual decisions. Notion AI versus Gemini Notebook compares these two study jobs.
Goodnotes: check local versus cloud transcription
Goodnotes can record while you write and replay the relationship between handwriting and audio on supported platforms. Its transcription FAQ separates supported Apple hardware with a downloaded local model from cloud transcription on Pro or AI Pass. Cloud use consumes AI credits and requires internet access.
The FAQ does not support importing an external audio file for transcription. It also limits transcription to three hours even if recording continues. Its cloud language list includes English and Danish; its displayed local list omits English. Confirm the actual local option before purchasing for offline English lectures.
Goodnotes pricing lists Essential at US$11.99 yearly, Pro at US$35.99 yearly and AI Pass at US$9.99 monthly in addition to an eligible base plan. Test audio recovery and an export, not just handwriting. The Goodnotes alternatives guide covers other notebook choices.
Check the policy for the feature you will use
Storage, transcription and optional AI can follow different paths. Local transcription does not make a separate cloud summary local. A company's no-training statement can also have feedback or opt-in conditions.
For example, Otter describes training on de-identified material; Notion describes no training without opt-in. Google distinguishes personal feedback from managed Workspace accounts. Goodnotes' privacy policy includes AI improvement and consent conditions. Check the policy that applies to your account and intended feature.
Get permission before recording, then check whether uploading and sharing are permitted too. For restricted course, research or placement material, follow the institution's approved process.
A useful ten-minute comparison
Make a permitted sample containing a technical term, a number and a correction. For tools that require direct capture, record a comparable explanation in each app instead of assuming they accept the same uploaded file.
Check the transcript against the audio. Then examine a generated note: did it preserve the correction, identify an uncertain point and avoid inventing an example? Finally, find the explanation and open an export on another device. These checks reveal whether the workflow fits your course without pretending to be a general accuracy benchmark.
Where Notibo fits
Notibo records in the browser or accepts media uploads up to 50 MB. Direct recording runs up to two hours within the remaining minute allowance. Chrome and Edge can capture supported tab audio; phone recording needs the page in the foreground and screen unlocked.
It produces editable transcripts and notes, with Word or PDF export. Pro adds recording-based flashcards and scheduled review; cards are not editable. PDF, PPTX and DOCX documents can also produce study material. Check the generated content against the source, especially technical details and long notes that may be truncated.
Notibo has no stylus notebook, retained audio player or transcript timecodes. Keep your own audio because successful processing deletes the uploaded recording. Storage is in Frankfurt; transcription and notes use US processors under contractual safeguards. Notibo does not train models on your content.
The 14-day Pro trial includes 240 total minutes, starting with your first recording or the start button. Free then has 30 monthly minutes and five documents. Pro provides 1,200 monthly minutes for €9.99 monthly or €88.99 yearly. Try it when producing editable lecture material is the task you need help with.
