Larkup Logo

Larkup is an open source platform that lets you build a private AI over your own files, websites, databases, and connected tools. Chat with your data, analyze it, or expose it through a live API. There is no pipeline to configure before you start. Open the app, provide your API key, load content from the Data page, and start chatting. Indexing, the RAG server, and model selection run behind the scenes.

​
What you can do with Larkup

  • Build a smart search engine: Turn any data, files, websites, databases, or connected tools into a private AI you can chat with.
  • Run local AI models: Keep your data under your control by connecting to local models or any provider you choose.
  • Chat with video: Import YouTube videos or upload media and ask questions with timestamped answers.
  • Load data from multiple sources: Easily index websites, files (PDF, CSV, Excel), raw text, and integrations (Notion, Slack).
  • Deep CSV analysis: Upload spreadsheets and get complex data analysis, charts, and summaries inline in chat.
  • Setup and deploy AI Agents: Launch your custom AI Agent server and connect to it via the SDK or REST API.
  • Customize your Agent: Fully brand your assistant, define instructions, and equip it with specific data and tools.
