InfraNodus

Paste in an interview transcript, a PDF or a set of web pages and get a network graph of the ideas inside it, with gaps between topics marked out.

That is the core job of InfraNodus, an AI knowledge graph and text analysis tool that pairs network visualization with GPT models to generate insights from your writing and research material.

It also lists text generation among its uses, so you can work from the graph toward new ideas.

InfraNodus offers a free tier, plus paid plans billed monthly.

Basic is $12 and covers personal or academic use, with a Chrome and Firefox extension, an Obsidian graph view plugin, web imports and 40 GPT-4 credits an hour.

Advanced is $32 and adds API access, commercial use, larger uploads and live graph updates.

Premium is $66 and adds training, the largest upload limits and 500 GPT-4 credits an hour.

Each paid plan has a 14-day trial.

Upload sizes and AI credits climb with each tier, so heavy PDF users should check the limits first.
