Why AskSia
What makes AskSia a better way to transcribe video to text.
Most transcription tools were built around live meeting audio. AskSia handles full video content: lectures, webinars, interviews, podcasts in video form, and YouTube clips. The transcripts come out clean and ready to use.
40+ languages, with translation
Transcribe a Mandarin lecture into English notes, or a Spanish interview into German. AskSia detects the source language automatically and runs translation alongside the transcript in any direction.
Auto-detect plus translate
Every video format and source
Upload MP4, MOV, WEBM, MKV, AVI, FLV, M4V, or any other common video file. Paste a YouTube or Vimeo link. Drop in a screen recording or a Zoom export. One tool covers them all without conversion.
MP4, MOV, WEBM, YouTube, Vimeo
An AI assistant on the transcript
Once the video is transcribed, you can ask Sia to summarize it, generate questions, pull a list of key topics, or extract direct quotes. The transcript becomes a starting point, not a final deliverable.

FAQ
Common questions about transcribing video to text.
How do I transcribe a video to text?
Open AskSia, upload your video file, and the AI does the rest. Supported video formats include MP4, MOV, WEBM, MKV, AVI, FLV, and M4V. You can also paste a YouTube or Vimeo URL instead of uploading. The transcript appears in seconds with speaker labels and timestamps, and can be translated into more than 40 languages or exported as TXT, DOCX, or SRT subtitles.
What video formats does AskSia accept?
AskSia accepts MP4, MOV, WEBM, MKV, AVI, FLV, M4V, and most other common video formats, along with YouTube and Vimeo URLs. There is no need to convert the file first or extract the audio.
Can I transcribe a YouTube video to text?
Yes. Paste any public YouTube URL into AskSia and the transcript is generated in seconds, complete with timestamps and automatic speaker identification. Vimeo links work the same way. Private or unlisted videos require you to upload the file directly.
How long can the video be?
The free plan supports videos up to 30 minutes per file, with unlimited live recording sessions. AskSia Pro and AskSia Super remove the duration limit entirely, which is useful for full lectures, multi-hour interviews, and long webinars.
How accurate is the video transcription?
On clear audio, AskSia reaches 95 percent or higher accuracy. Real videos rarely have perfect audio, so accuracy varies with background noise, accents, and audio quality. The model uses context, which helps it pick up technical and academic vocabulary that generic transcribers usually miss.
Can I translate the video transcript into another language?
Yes. AskSia transcribes and translates at the same time, so you can read the original transcript in one language and the translated version in another, side by side. More than 40 target languages are supported, and the source language is detected automatically.
How much does it cost to transcribe video to text on AskSia?
AskSia is free to start, with no credit card required. The free plan covers videos up to 30 minutes each. AskSia Pro and AskSia Super remove the time limit and unlock additional features like Google Docs export, higher-accuracy tiers, and the full AI study companion.
