A browser-based workspace for exploring graph and embedding data with filtering, search, timelines, public sharing and an optional AI Assistant. It accepts CSV, JSON, Parquet and Arrow data, and unsaved graphs can be explored without signing in.
Why I recommend it: Free for personal, educational and other noncommercial use; commercial use requires a paid license. Sign-in is required to save graphs and use the Assistant's limited free allowance.
Apache 2.0 open-source search infrastructure for AI applications, supporting vector, full-text, regex and metadata search, free to run locally with optional hosted cloud.
Why I recommend it: The free local version is enough to build and demo an AI project of your own — a portfolio piece that shows you can work with retrieval, not just prompts.
