Inside Lecture Processor

The slides say what.
The recording explains why.

Keep both. Transcribe a lecture recording, extract the text from PDF or PowerPoint slides, and combine them into comprehensive, structured study notes.

Encoding → storage → retrieval

LECTURE RECORDING

“Retrieval is an active process. Try recalling an idea before you look at your notes.”

COMBINED NOTESIllustrative example

How retrieval supports memory

Information is encoded, stored, and later retrieved. Practising retrieval means bringing an idea to mind before checking the source.

Study prompt: explain retrieval in your own words.

From two sources to one document

Less switching between
slides and recordings.

A slide often contains the outline; the spoken explanation supplies the context. Lecture Notes brings those sources together so you can review one connected document.

  1. 1

    Add your sources

    Upload PDF or PPTX slides and an audio recording. You can also record in your browser or import a supported lecture link.

  2. 2

    Transcribe, extract, combine

    The recording becomes a transcript. Text is extracted from the slides. Both are combined into structured notes.

  3. 3

    Review and make it yours

    Read and edit the result, then use optional flashcards and practice questions to work with the material.

For conversations and research

An interview you can
read, quote, and code.

Interview Transcription formats the recording with timecodes and speaker labels. Add a concise summary or a version organized into sections when you need them.

Open the transcript in the coding workspace to label quotations, organize codes, and review an AI coding draft before accepting it.

Open Interview Transcription

Optional summary and sectioned-transcript outputs use separate add-on credits.

INTERVIEW TRANSCRIPTFormatting example
Onderzoeker

Wat helpt je om een college te onthouden?

Geïnterviewde

Ik probeer eerst zelf uit te leggen wat ik heb geleerd. Daarna kijk ik terug in mijn aantekeningen.

Onderzoeker

En wat doe je als je iets niet meer weet?

Geïnterviewde

Dan markeer ik dat onderwerp om het later opnieuw te oefenen.

Timestamps and speaker labels keep each turn easy to follow.

A whole week of material

Handle a queue.
Or just one small task.

Use batch processing for several items, and focused tools when you only need a transcript or an extraction.

One batch, clear results.

Choose a processing type: lecture pairs, slides, interviews, audio files, or slide-text/transcript-text pairs. Set shared options, adjust individual rows, and follow the batch on Batch Status.
