If you feel like it please write in to [email protected] and we can set up a meet. I'd love to learn what we're doing wrong and potentially go through the support & improvements we've built.
This article should help as well. It's documenting not just the shortcuts but also how to perform different flows.
I feel for you. I'm blind in one eye and am at a pretty high risk of going blind in the other because of it. I do my best to make sure the things I build are accessible; it's a real shame that accessibility is typically an afterthought.
I didn't specifically target this as utility for visually impaired users(as we weren't able to test with such users), but was under opinion that it would help them if someone from the team shared links with our bot.
Reading your comment & that of others reg accessbility on slack makes me wonder if even when audio summary of URLs is received, whether someone with accessbility issues can click the player button.
On the same topic: your landing page does a bad job of displaying what your app does and why it is useful for me as a user. I had to watch the "how to use" video to get an understanding.
Users who received larynx content said they liked the voice summary of web content which their contacts sent to them & asked for a feature to summarise web content on-demand.
Hence, we released it as bots for Messenger, Telegram, Twitter & slack. I agree that the website portion of larynxBot can do a better job at explaining it.
