Link and citation checker
AI writes links from memory and quotes pages for things they never say. Vouch opens every link live and reads the source: what loads, what moved, what is gone, and whether the quote is really on the page.
Every redirect hop, the final address, the page title, a "page not found" page that still answers 200, a deep link that lands on the front page, and #section anchors that no longer exist. For a dead page, the closest real pages from the site's own sitemap.
Vouch reads the source's visible text and says per quote: word for word, only punctuation changed, wording changed, a number changed, or not there at all. It shows the passage it found so you can judge.
Sites that turn away automated checks are marked blocked, not dead. Pages built only by JavaScript can hide text and anchors. A matching quote shows the words are there, not that the claim is true. PDFs are not read.
Add the MCP server https://vouch.clawhard.com/mcp (tools vouch_check_links and vouch_check_quote) or call the JSON API described at /openapi.json. Before an agent fetches a docs URL it wrote from memory, or hands you a README, report or answer with sources, it can check every link and quote and fix what is dead or misquoted.
Add Vouch to ChatGPT, Claude, Cursor or any assistant that supports MCP, then ask it to check that links load (no 404s, soft 404s or missing anchors, with the closest real page) and that a page really contains a quote. No key, no login.

Vouch checks links and quotes against the live web: which links load, redirect, 404, soft-404 or point to a missing #anchor (with the closest real page from the site's sitemap), and whether a page really contains a quote, word for word or with changed words and numbers. No account.
Paste the text into Vouch (or give the list of addresses). It fetches every link live and tells you which load, which redirect and where, which are gone, which are "page not found" pages that still answer 200, and which #section anchors do not exist. For broken links it suggests the closest real pages from the site's sitemap.
A soft 404 is a missing page that does not admit it: the server answers 200 OK but shows a "page not found" message, or quietly redirects the deep link to the front page. Simple link checkers count those as working. Vouch flags them from the page title and heading and from redirects that land on the home page.
Give Vouch the source address and the quote. It reads the page's visible text and reports whether the quote appears word for word, with only punctuation or capitals changed, with different wording or different numbers, or not at all, and shows the passage it found so you can judge.
Some sites turn away automated requests with HTTP 401, 403 or 429 or a bot challenge page. That says nothing about whether the page exists, so Vouch reports it as blocked rather than broken. Open those links in a browser to be sure.
Yes. Add the MCP server https://vouch.clawhard.com/mcp (tools vouch_check_links and vouch_check_quote) or call the JSON API described at /openapi.json. It is also on the Clawhard MCP server at https://mcp.clawhard.com/mcp.
