Add FactIQ to Claude

Works in Claude web, desktop, and Cowork·Requires a paid Claude plan·FactIQ is free to start

Set up

FactIQ is listed in the official Claude directory. This is the quickest way to install it: you do not add a marketplace or paste a repository.For the best experience, use Cowork. Basic FactIQ questions also work in Claude Chat, but advanced reports and local visualizations work best in Cowork.

  1. 1

    Open FactIQ in the Claude directory

    Go to claude.ai/directory/factiq while you are signed in to Claude. You can also open Customize → Plugins in the left sidebar, browse the directory, and search for FactIQ.

  2. 2

    Click Connect and sign in

    On the FactIQ listing, click Connect, complete the FactIQ sign-in, then start a new chat. Claude adds the FactIQ skill and the FactIQ connector to your account. OAuth grants read-only factiq:read access and no API key is required.

  3. 3

    Verify the installation

    Confirm FactIQ shows as installed under Customize → Plugins and as connected under Customize → Connectors. Ask a test question and confirm Claude invokes FactIQ and returns sourced data.

Update or remove FactIQ

ActionWhat to do
Update (GitHub install)If you installed FactIQ from GitHub, open Settings → Customize → Plugins, click Add in the top right, and choose Manage marketplaces. Click the three dots next to factiq-plugin, then click Check for updates.To get updates without doing this again, turn on Sync automatically in the same menu. Claude then re-syncs FactIQ when the plugin changes on GitHub.
Remove accessUninstall the FactIQ plugin, then disconnect FactIQ under Customize → Connectors.

Organization-managed installs sync from your private copy of the repo, which does not track ours automatically. To pick up plugin updates, pull from defog-ai/factiq-plugin and push to your mirror (or re-upload the ZIP for manual marketplaces).

Try it

Ask an economic or financial question normally — Claude selects the FactIQ skill automatically. Type /factiq to choose it explicitly.

  • Across Nvidia’s latest four covered earnings calls, how did management’s data-center demand commentary change? Check coverage first, identify the exact fiscal periods, and search each quarter separately using “data center demand,” “accelerated computing,” “AI infrastructure,” and company-native alternatives. Return verbatim quotes with speaker/role, section, call date, fiscal period, and citations; list missing quarters and cap hits.
  • Compare what Microsoft management said about AI infrastructure spending in covered earnings calls with executive media from the same period. Use verbatim quotes for earnings; keep FactIQ media paraphrases unquoted with person/role, title/channel, publication date, and timestamped links. Independently verify a media source before quoting it. Separate evidence from inference and identify coverage gaps.
  • What's the US unemployment rate, charted over the last 10 years?

Troubleshooting

Plugins or Cowork are unavailable
Plugins require a paid plan. On Team and Enterprise, ask an Owner or Primary Owner to turn on Cowork under Organization settings → Capabilities, then turn on Code execution and file creation and Skills under Organization settings → Skills.If custom plugin installation is still restricted, the Owner can install FactIQ for the whole organization — see the Organization tab under Set up. The FactIQ plugin is open source; review its source code on GitHub.
FactIQ does not appear in the directory
Sign in to Claude first, then open claude.ai/directory/factiq. If your organization blocks directory plugins, ask an Owner to allow FactIQ, or use the Organization tab under Set up.
Marketplace does not appear
Confirm the repository is exactly defog-ai/factiq-plugin. Organization policy can block custom plugin sources.
Marketplace is installed but the plugin does not appear
For organization marketplaces, the FactIQ plugin's installation preference may be set to Not available, which hides it from members even though the marketplace shows as installed. An Owner can change it to Available for install or Installed by default under Organization settings → Plugins. Members see the change on their next session.
Organization marketplace fails to sync from GitHub
Confirm your copy of the repo is private (a fork of our public repo stays public — duplicate it instead, as shown in the Organization tab under Set up) and that the Claude GitHub App has been granted access to it. If GitHub configuration remains a blocker, bypass it entirely: download the plugin as a ZIP file and upload it as a manual marketplace under Organization settings → Plugins.
OAuth gets stuck
Sign in to FactIQ in the same browser, then re-run Connect. You can also remove and re-add the connector from Claude settings.
Tools missing in chat
Start a fresh conversation after installation. Type /factiq to select FactIQ explicitly, or open Connectors in the composer and confirm FactIQ is enabled.
Claude Code is separate
Plugins installed in Claude don't appear in Claude Code — it has its own install path. See the Claude Code guide.
