April Flow is a sovereign AI assistant that answers questions from document Collections selected by the user.
What April Flow is
April Flow is a sovereign AI assistant that answers questions from document Collections selected by the user. It searches only the chosen Collections and includes supporting document extracts in answers; users can open originals and inspect highlighted passages. Its website assistant also uses selected Collection content rather than automatically reading public websites. The same Collections are available through the app, API, website assistant, customer portal, internal applications, and workflow integrations. Java and Python SDKs plus a Python scraper CLI support document uploads, querying, and workflow building. April Flow can run as a managed service or inside an organization’s infrastructure. Self-hosting is intended for control over data, infrastructure, AI processing, governance, and operating costs, including independence from external AI services. Starter, Team, and Business have increasing quotas and standard or priority support; Sovereign has custom deployment and pricing. Quota limits can pause questions, uploads, or indexing until renewal, added capacity, or an upgrade.
