I am a computer scientist who can't claim credit on the latest advances regarding AI. I guess only a handful of people are truly eligible for that! Like the rest of us, I have been working on utilizing it to build tools.
Recently, I developed a self directed research and learning tool mainly for my own use (also released publicly below). The tool is basically free but the underlying AI models are not. It connects to AI models via Openrouter BYOK, so I need to basically pay Openrouter for the brokering as well as for the AI models such as Claude 4.6 or GPT 5.4. For my purposes, unfortunately, the free or low cost models are not that great as I could tell by the quality of the output.
I am not here to market my tool, it is free anyways, it is great if it inspires people. Learning to me is addictive, I spent $150 already while experimenting on this tool and I can imagine how easily it can get out of control.
I did my best to optimize the context that is sent to the LLM every round. A good learning session with 20-30 slides, Q/A and assessment is around $2-3 dollars on Opus 4.6, which is not too bad for a journal club treatment of a 30+ page research paper. But I can see how this can quickly add up for a researcher or a grad student.
I know NotebookLM exists but where is the joy of being able to develop your own tools?
