Lectures are long, dense, and easy to lose track of — especially when a professor moves fast through a proof, a case study, or a string of dates. Re-scrubbing through an hour of audio to find the one line you half-remember wastes study time you don't have. Transkio converts your recorded lectures into text you can search, skim, and copy straight into a study guide.
Whether you're a student capturing lectures on your phone, a TA producing accessible materials for a course, or an international student who needs a translated version to review key terms, a transcript turns a one-time listening experience into a reusable study resource. Upload the recording once and get a document you can revisit before every exam.
Re-listening to lectures doesn't scale when exams are close
A single semester can produce dozens of hours of recorded lectures, and most students only ever engage with that audio once — during the lecture itself. When it's time to review for a midterm or final, scrubbing back through hour-long recordings to relocate a specific explanation or definition is slow and frustrating, and it's easy to skip past exactly the section you needed.
It gets harder for ESL and international students, who may need to slow down, re-read, or translate unfamiliar terminology to fully absorb dense material — something that's nearly impossible to do with audio alone. And for courses with active Q&A, a recording that blends the professor's voice with student questions makes it even harder to follow who said what when you're reviewing later.
Upload the recording, get a study-ready transcript
Transkio transcribes lecture recordings into clean, readable text you can search with Ctrl+F instead of scrubbing a timeline. Upload an audio file or a recorded video export from Zoom, Panopto, or similar tools, and get a transcript back you can read, highlight, and paste into your own notes.
On Elite and above, Q&A-heavy lectures get labeled by speaker so you can tell the professor's explanation apart from a classmate's question. Elite plans add AI-generated summaries and key points for fast pre-exam review, and Pro plans let international students get a translated text version in 50+ languages to check comprehension.

Economics lecture — the Fed's dual mandate
so today we're gonna talk about um the fed's dual mandate right so basically there's two goals maximum employment and price stability and uh a lot of students get confused because they think the fed only cares about inflation but that's that's not really true um so lets back up and think about why price stability matters so like if inflation is too high peoples purchasing power erodes and businesses cant plan long term contracts and stuff
Today we're discussing the Federal Reserve's dual mandate. The Fed pursues two goals: maximum employment and price stability. Many students assume the Fed only targets inflation, but that's not accurate. Price stability matters because high inflation erodes purchasing power and makes it difficult for businesses to plan long-term contracts.
Frequently asked questions
How long can my lecture recording be?
The free plan includes 60 trial minutes with no card required, then 30 minutes every month, with a 100MB max file size and up to 30 minutes per recording. That covers most single lectures; longer sessions or heavier course loads fit better on a paid plan with higher limits.
Can Transkio tell different speakers apart during Q&A?
Yes. Speaker detection is available on Elite plans and above, so a lecture with a Q&A segment gets labeled by speaker instead of running together as one continuous block of text.
Can I get a summary of key points for exam review?
Yes. Elite plans generate an AI summary and key points for each transcript, so you can review the gist of a lecture quickly before deciding which sections to read in full.
Does Transkio translate my lecture transcript?
Pro plans and above can translate your transcript into 50+ languages. Note that translation currently applies to the text transcript only — translated SRT or VTT caption files aren't available yet, so translated exports come as plain text.
What lecture recording formats can I upload?
Transkio accepts common audio formats (MP3, WAV, M4A, AAC, OGG, OPUS, FLAC) and video formats (MP4, MOV, WebM, MKV, MPEG), which covers most phone recordings as well as exported captures from tools like Zoom and Panopto.
