In short. Kagi Assistant documents a 50 MB limit for webpages and online documents fetched from a URL.
Definition: Kagi Assistant can fetch a webpage or online document of up to 50 MB for use as conversation context. Uploaded files follow a separate 30 MB maximum.
Key facts
- Kagi's Assistant documentation sets the online webpage and document retrieval limit at 50 MB.
- The same documentation says to paste the URL into the Assistant conversation with the Entire Web toggle on.
- Kagi documents a separate 30 MB maximum for files uploaded through the Assistant's paperclip control.
- Kagi's Universal Summarizer API documentation lists URL and text as mutually exclusive inputs and gives that API a separate 1 MB total request-size limit.
What is the size limit for an online document?
The limit documented for Assistant URL retrieval is 50 MB. Kagi describes the feature as fetching “webpages and online documents” for use as context in a conversation. The page does not define whether “MB” means decimal megabytes or a binary unit.
The limit applies to content fetched from a URL. Kagi's wording covers both webpages and online documents, so a document hosted online belongs to this retrieval path when its URL is pasted into the conversation.
How is URL retrieval enabled?
Kagi says that Assistant web access is controlled with a button below the prompt field. The same page describes web access as powered by Kagi Search and says that you can enable it for an initial question and disable it for later questions in the same thread.
For a direct URL, the instructions are to paste the address into the Assistant conversation and turn on the Entire Web toggle. Kagi also documents an internet URL parameter: true enables internet access, while another value disables it and overrides the profile setting. The documented pattern is:
https://kagi.com/assistant?internet=true
How does this differ from uploads and the Summarizer API?
An uploaded file is a different input path. The Assistant documentation gives uploads a maximum file size of 30 MB and says that uploaded content remains in the conversation context for later messages. That 30 MB figure should be used when the file is attached from the device rather than fetched from an online URL.
Kagi's Universal Summarizer API documentation describes a separate endpoint that accepts either a document URL or text. It lists text web pages, PDF and PowerPoint documents among its supported content, and states that the API can summarize content of any length. The same documentation then states that total request size is limited to 1 MB. That API request limit is part of the Summarizer interface; the Assistant documentation gives the Assistant URL-fetch limit as 50 MB.
