In short. Kagi documents PDF, PPTX, MP3 and WAV inputs, with transcripts involved in its podcast and YouTube handling.
Definition: Kagi Summarize, also called Universal Summarizer, is Kagi's tool for summarizing web pages and media from a URL. Kagi's API documentation documents direct support for PDF, PPTX, MP3 and other listed formats, while its product description makes a transcript a condition for podcasts.
Key facts
- Kagi's Summarize documentation says the website accepts the URL of a web page, PDF, PPTX, MP3, video or other content for summarization.
- The Universal Summarizer API documentation lists PDF, PowerPoint, Word, MP3 or WAV, experimental YouTube URLs, and scanned PDFs or images processed with OCR.
- Kagi's Universal Summarizer announcement, dated March 23, 2023, says YouTube handling used available video transcripts and lists audio or podcast support for MP3, WAV and AAC.
How does Kagi handle these source formats?
Kagi's current documentation presents the URL as the website input. The page describes Kagi Summarize as a tool for summarizing “any page, video or podcast (given a transcript)” and then gives the website input as a URL for a web page, PDF, PPTX, MP3, video or other content. A page owner therefore has a documented path for publishing a supported file or media resource at a URL.
The API page adds a format list. It names text web pages, articles and forum threads, PDF documents with the .pdf extension, PowerPoint documents with .pptx, Word documents with .docx, audio files in MP3 or WAV, experimental YouTube URLs, and scanned PDFs and images through OCR. The same page says the Universal Summarizer can summarize content of any length.
What does transcript-dependent media mean?
Kagi's product description attaches “given a transcript” to podcasts. Its current API list marks YouTube URLs as experimental. Kagi's March 23, 2023 announcement is more specific about the media path: “YouTube videos. We are currently using available video transcripts. In the future we will be summarizing videos directly.” The announcement also describes “Audio/Podcasts. Supported mp3 and wav formats” and says that one hour of audio is transcribed in real time in about 10 seconds.
The public pages establish that Kagi can use transcripts for some media and that the API lists audio files. They leave unspecified whether every arbitrary audio URL without an available transcript is transcribed before summarization.
!sum https://www.youtube.com/watch?v=JwLDrZmNIIA
The Summarize documentation gives this !sum example for opening a YouTube URL from a search or URL bar. For API users, the documented document endpoint is:
GET/POST /summarize
The API accepts either a document URL or passed text, with those two inputs exclusive. A URL-based request is the relevant path for a hosted PDF, slide deck or media file.
What should a website owner check?
Check the file extension and the media's transcript availability against Kagi's API list. A PDF, PPTX, DOCX, MP3 or WAV URL matches a format named there. A YouTube URL is documented as experimental, and Kagi's product description ties podcast summarization to a transcript. The docs therefore describe format and transcript conditions, while the exact result for a particular URL remains dependent on how Kagi processes that resource.
