Verdict
Use Open WebUI if you want a browser-based interface over local or cloud providers and you are comfortable managing a self-hosted-style setup. Use AnythingLLM if your main goal is a document/workspace-oriented app for chatting with files and organizing knowledge workflows. Both can be part of local/private AI setups, but neither should be treated as automatically private without checking provider, embedding, storage, telemetry, and network settings.
