InstaGraph
InstaGraph turns text prompts or URLs into interactive knowledge graphs. Type a topic like "Solar System" or paste a link, and the service maps entities and how they connect in a visual graph you can browse and share.
The hosted web app grew out of Yohei Nakajima's open source InstaGraph project, from the same creator behind BabyAGI. GPT generates the nodes and relationships from your input, and finished graphs can appear in a public gallery for others to explore.
Students, researchers, and analysts use it when they want to see how concepts link together instead of reading a wall of text. Google sign-in is required to create graphs.

Report bugs or request features through the GitHub support repo
Free to use with no pricing page or paid tiers listed on the site.
Open source codebase on GitHub alongside the hosted service.
Public graph gallery lets you explore community examples before creating your own.
Visual graph output makes entity relationships easier to scan than plain text.
Google account sign-in is required; no alternative auth method is listed on the site.
No dedicated support email or contact page beyond GitHub issue tracking.
Graph quality depends on GPT generation, so results may vary by prompt.
Is InstaGraph free to use?
InstaGraph does not list paid plans or pricing tiers on its website. The hosted service appears free to use after you sign in with a Google account.
Do I need a Google account to use InstaGraph?
Yes. InstaGraph requires you to sign in with a Google account before you can create knowledge graphs on the hosted web service.
How does InstaGraph create knowledge graphs?
InstaGraph accepts natural language prompts or URLs as input. GPT generates entities and relationships from that input, then renders them as an interactive knowledge graph you can view in the browser.
Can I browse graphs created by other InstaGraph users?
Yes. InstaGraph maintains a public graphs gallery on instagraph.ai/list where you can view community-created knowledge graphs before signing in.
Who created InstaGraph?
InstaGraph was started by Yohei Nakajima, a venture capitalist and the creator of BabyAGI. The instagraph.ai team turned his open source project into a hosted web service.
Is InstaGraph open source?
Yes. The original InstaGraph codebase is available on GitHub at github.com/yoheinakajima/instagraph. Bug reports and suggestions for the hosted service go to the InstaGraph-Support repository on GitHub.
