Turn videos, podcasts and recordings into accurate transcripts. Paste a YouTube or Bilibili video link, a direct link to a podcast episode or audio file, or upload an audio or video file, and Waper writes the transcript, a summary and chapters, translated into your language. Every passage has a timestamp you can play back from; save it to a knowledge base, and your agent can keep working with it.
What it does and which platforms it supports: Video to text on waper.ai.
Supported: YouTube, Bilibili, direct links to podcast episodes and audio files, and audio or video files from your computer. Playlists, live streams and paid content aren't supported.
Below the box is all the audio and video in your library, grouped by date, with a filter by source (All, YouTube, Bilibili, Podcasts & audio, Uploads). Each row shows the source, length and knowledge base; one in progress shows its current step, and a failed one says why and can be retried.
When processing finishes, existing feed episode titles or upload filenames are kept. Direct audio links without a title use the filename without its extension.
The page shows three steps: getting the content → turning it into text → writing the summary. The transcript appears as it goes, so you don't need to wait around: it'll show up in Notetaker (and your library) when it's ready, and you'll get a reminder from Kiki in its chat.
If the service restarts while preparing the audio, the job prepares it again automatically. The upload is kept until preparation completes so processing can continue, within the temporary upload's 12-hour retention period.
While processing, the length may be an estimate. Once audio is decoded, its actual length is used consistently in the completed item’s details, Notetaker list and Library list.
On a wide screen the player, title, source and chapters are on the left, and the "Summary" and "Transcript" tabs on the right. On a phone the player is at the top and shrinks into a mini player bar as you scroll.
Select any timestamp (a key point, a chapter, a transcript passage) and the player jumps there:
Below are a few follow-ups (pull out action items, write it up as an article in a knowledge base, list notable quotes); selecting one hands it to your agent.
For direct audio links and uploads, Waper prefers the file's title, show name and author tags. Without tags, it uses the filename without the link's query parameters. The price may initially show a filename; tags are filled in after downloading.
Each recording gets one note of your own:
The "Ask" button at the top right names who you'll ask: opened beside a chat, it's that chat's agent and the cursor goes straight into the chat's input box; opened on its own, it's the agent that transcribed it (your main agent if it wasn't done in a chat), opened beside the page. Either way it has this recording as context, so you can ask about it; citations carry timestamp links like [12:30]. The agent can go on to save the result to a knowledge base or set up a watch.
"More" has Open original, Export (Markdown, SRT subtitles, TXT), Move to knowledge base and Delete. Markdown includes the overview, key points, chapters and the timestamped transcript; SRT uses each passage's start and end times; TXT is one passage per line with its timestamp.
When the transcript or summary isn't in your content language, the page shows it translated into your content language by default (passage by passage, same timestamps), and you can switch back to the original or to bilingual any time. Each language is translated once and shared, at no charge.
One price by length: 6 credits a minute (each started minute counts). The transcript, the summary and the translation into your language are all included.
When you ask your agent to transcribe a link, the chat shows a progress card. When it would cost more than the credits you have left, or a lot at once, the agent shows a price card first and starts only when you confirm. Once the transcript is ready, the agent continues in the same chat with what you asked for (a summary, notes, an answer); you don't need to ask again. The recording shows up in Notetaker and your library as well.
Videos and podcasts picked into a brief get transcripts filled in behind the scenes (not charged to you), and the entry's summary is rewritten from the transcript. Open it with "Transcript & chapters" on the brief entry; it appears in Notetaker once you save it.
Your agent, MCP and the API can all read transcripts and start a transcription (charged the same way). See MCP and API.
Free handles recordings up to 60 minutes each; Personal and Pro go by credits rather than a plan cap, up to 10 hours each (which only keeps out unusually large files). Uploads included. Background transcriptions from your watches aren't held to your plan's cap (4 hours at most).
Failures distinguish regional or licensing restrictions, temporary download failures, and unsupported content. Retry a temporary download failure later. If the source restricts access, try another source or upload a file you can access.
