[BlindMath] I'm blind! I love math! I want to go higher than high school geometry.

I am somewhat biased in this answer because as many of you know I was in on the Graphiti development. Just adding this note for completeness. I don't make any money off my following statement.
The problem with using an AI is they are not always right. I am blind and have been using a Graphiti since 2017 to see graphs and there is nothing like it out there. If people are going to do complex math it is worth getting your school to get one if you can not afford one yourself. The graphiti plus has a line of 40 cells of braille under the graphic 40 by 60 5 level pin field and the first ones are being sent out as we speak. The older Graphiti still has the same graphics panel and you can zoom and move around a grid reading the actual text as well as feeling the overall view of the graphic in question. It can be used with HDMI so it can be used as a monitor with no extra software. Like I said their e is nothing out there like it. One Blind person used it to see the representation of proteins and you can find that article online. If you can't let me know. The graphiti also directly connects to the Orion Ti-84 and again you can read the screen including the coordinates by touch.

Hello,
Concerning text description of graphs, I recently used Be My AI for this purpose. The process still requires a few steps if you work from a Windows computer, as you will need to send the graph to your Android or Apple device, but the description of plots is quite insightful (including descriptions of line crossings and tangential points) and I was very happy with the result. I hope such features are soon available to use from a laptop computer and that automated graph descriptions are further refined.
Kind regards,
Bert
