Does slideshare.net block AI crawlers?

Yes, 4 of 17. As of October 19, 2026, slideshare.net's robots.txt blocks ClaudeBot, CCBot, Bytespider and Diffbot from the whole site. It keeps the other 13 out of parts of the site. 4 of them are named in a group of their own; the others follow its rules for every crawler.

Its /llms.txt returns an HTML page, not an llms.txt file. Its homepage is 136,113 tokens of raw HTML, 755 as Markdown (0.6%) and 217 pruned for the question “What is slideshare.net?”.

Each crawler, by its robots.txt rules

From https://www.slideshare.net/robots.txt (1,443 bytes, 11 user-agent groups), parsed per RFC 9309. Blocked: no path allowed. Partly blocked: some paths disallowed. The rule counts are those of the groups that apply.

Read slideshare.net through ContextFetch

GET /r/ returns a page as Markdown, with X-Raw-Tokens and X-Output-Tokens headers. Add ?q= and a question to get only the passages that answer it. No key needed for 25 requests a day; a free key has 2,500 credits. slideshare.net's robots.txt partly blocks ContextFetchBot: our index and crawls skip what it disallows, and a page you ask for is fetched once on your behalf (see the bot page).
