I've used the free version of Claude for reducing imaging reports (MRIs and CT scans) to understandable summaries. Also for interpreting progress reports from physical, occupational, and speech therapists. For both the imaging and the therapy reports I fed in the reports over time and Claude did a good job helping me understand what progress/lack thereof that Mr wtg's therapists are seeing. Saved me a ton of time figuring out all the terminology.
I also used it to help figure out how to use ramps to facilitate wheelchair access to our house. It was lousy at that until I redirected it. And then it was still not very good. It did tell me which manufacturers have the highest quality products. It was probably a toss up whether it actually saved me time or not.
It gave a couple of off-the-wall interpretations about things that happened in therapy. It is much more "emotional" than I expected. I thought it would be more logical and detached.
It did a pretty good job comparing two OTC e-stim devices we were considering for home use to help try to wake up Mr wtg's arm.
I have found its fawning to be annoying. "You're so smart to have figured this out." "Mr wtg is so lucky to have you as an advocate in his corner." I haven't asked it to stop doing this yet, but I'm pretty close.
The mini-AIs that are in Amazon that answer questions about various products are basically useless at this point. And duck.ai (pops up in DuckDuckGo searches) and Leo (part of Brave) also have pretty limited use.
Haven't done anything beyond that.
I feel like I did when I first started using Netscape and AltaVista to access the info on the internet. The information and analysis that are available is amazing. But I'm also a bit troubled by the quality of the results. I still feel like I have to double check a lot of things because it can miss information and its analysis can be flawed. That becomes apparent if you have any background in the topic at hand. The quality of the prompts is definitely a factor; you kind of have to figure out how to use it. If you don't and take it at face value I could see running into problems.
