Danswer is an AI-powered Q&A platform that helps teams quickly find and share knowledge from various sources, streamlining information retrieval and enhancing collaboration.
Danswer is an open-source, AI-powered question-answering platform that enables teams to query natural language questions against internal documents, workspace apps, and personal files, delivering reliable answers backed by direct quotes and source references for trusted information retrieval.[1][4] Its core value lies in streamlining knowledge discovery across diverse sources like Slack, GitHub, Confluence, Google Drive, and web scraping, using advanced semantic search, reranking with LLMs, and a custom deep learning model to interpret user intent accurately.[1][2]
Key features include user authentication with document-level access controls, a management dashboard for connectors and live updates, and simple one-line Docker Compose or Kubernetes deployment for self-hosting.[1][4] Designed for enterprises, engineering teams, HR departments, customer service groups, non-profits, and legal firms, it supports use cases such as centralizing employee FAQs, tracking project updates, and searching case files or technical specs.[2]
What sets Danswer apart is its permissively licensed (MIT) open-source nature, providing full data control, on-premise security, and customization of AI models—offering a flexible alternative to proprietary tools without vendor lock-in.[2][3][4]

[ToS] Explicitly states 'Danswer will not use Inputs or Outputs as inputs to train any AI-model (including any Third-Party LLM)' with only limited manual review permitted for accuracy improvement, not model training. This protection applies to all tiers.
“[ToS] 'Danswer will not use Inputs or Outputs as inputs to train any AI-model (including any Third-Party LLM), however Danswer may manually review Outputs produced by the Services against the Inputs and the underlying data from which the Output was made to build, train, and improve the accuracy of our automated methods of processing.'”

[ToS] Explicitly states Customer retains all ownership of Input and Output. Danswer retains no rights to customer-generated content. Customer has no claim against Danswer for similar outputs generated for other users, but this does not diminish customer's exclusive ownership of their own outputs.
“[ToS] 'For purposes of this Agreement and as between the parties, Input and Output are both deemed Customer Materials (and Customer shall retain all ownership of such Customer Materials, as permitted under applicable law).'”
[ToS] Establishes 'commercially reasonable information security program' but no specific compliance certifications (SOC 2, ISO 27001, GDPR, HIPAA) are mentioned in provided documents. No dedicated security or trust page referenced. Absence of explicit certifications warrants moderate concern score.
