Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
API docs that humans and AI agents ship together
Paste an OpenAPI, GraphQL, gRPC, SOAP, or AsyncAPI spec and Theneo builds a complete, navigable API reference with code samples and a versioned playground.
Engineers, writers, and PMs edit in the same document with live cursors, comments, version history, and one-click rollback, so docs stop drifting from the product.
Automatic changelog generation flags breaking changes as APIs evolve, keeping a timeline developers can trust.
An Ask AI assistant answers developer questions from your docs, and an MCP server plus llms.txt make the content usable by coding agents.
