DocsGPT
DocsGPT is an open-source platform for private AI agents, assistants and enterprise search over an organisation's own documents, built by Arc53. It runs where the data is allowed to be: Arc53's EU cloud, a dedicated managed instance, the organisation's own servers, or fully air-gapped with no outbound traffic.
Teams connect files and services (PDF, DOCX, XLSX, scanned documents with OCR, Google Drive, SharePoint, Confluence, GitHub, S3) and get answers cited to the source passage. Agents call tools and APIs with per-action approval, a visual builder turns document jobs into workflows, and agents can produce DOCX, XLSX, PPTX and PDF files.
Any model works: OpenAI, Anthropic, Google and others in the cloud, or local models through Ollama or vLLM. Governance covers OIDC SSO, SCIM 2.0, role-based access, guardrails, usage quotas and an exportable, append-only audit log. MIT licence, 18,000+ GitHub stars.
