Trustworthy knowledge for your agents, your site and every visitor

Build a cited library from your docs and pages, then connect it to Claude, Codex or Cursor, embed it on your own site, or share it as a page of its own. Every answer keeps its source.

Get an API keyTry it online

Add an MCP server named "re0" at https://re0.io/mcp using HTTP transport, then confirm it is connected and list the tools it exposes.

Paste it into Claude, Codex, Cursor or any client that can edit its own MCP config, and let the model do the setup.

  • Public libraries are free to query
  • Every answer keeps its citation
  • One library behind agents, widget and shared page

  • Connect your agent

    Plug it into Claude, Codex, Cursor or an agent of your own over MCP or the API, every result cited.

    Browse libraries to connect

  • Put it on your site

    Paste one line of script and visitors ask in the corner; answers come from your content only, with the page cited.

Put the same answers on your own site

Build a library from your website or docs, paste one line of script, and a chat bubble answers visitors from your content only, citing the pages it used and opening them on request.

  • One script tag; no build step and no changes to your pages
  • Answers come only from your library, with the source page beside each one
  • An allowlist of origins and a daily limit keep the key safe to publish

The whole integration

<script src="https://re0.io/widget.js" data-site-key="mm_site_…" async></script>

Create a site key on a library’s page in the dashboard; the snippet is ready to copy there.

Shared page

Share a library as a page of its own

Turn a library into a standalone company or product page: an introduction drafted from its own content on top, and underneath a Q&A that answers visitors from the library only, every sentence cited. Send the link, or print the QR code.

  • A first draft is written from the library; edit it and publish, with no review queue
  • Public or link-only, with an optional password and expiry date
  • Visitors leave their contact when the answer is not there, and the leads land in your dashboard

Publisher revenue share

Publish an expert library and earn on every retrieval

Each month the platform sets aside 20% of its net revenue and shares it among expert-library publishers by retrieval count. When someone retrieves from your library through an agent or the API, that retrieval’s share is credited to you.

See the revenue rulesEarnings never touch ranking, and readers never pay more for them.
  1. 1

    Publish and earn the expert tag

    Publish a public library and claim its sources, then apply for the expert tag on the library page. Earnings start once an administrator approves.

  2. 2

    Every retrieval accrues

    Each read of your library from another workspace counts toward the month’s share. Your own reads, linked workspaces and one reader’s reads beyond 200 a day do not.

  3. 3

    Settled monthly, as calls or cash

    The month closes, and after a 45-day hold the earnings can become calls, or be paid out to PayPal once they reach $20.00.

Start with one traceable query

Less guessing from your agent, more grounding.
