Just figured out yesterday that OpenBoard is abandoned and jumped over to Heliboard, thanks to the announcement for 1.0 in this community. The top comment mentioning FUTO Voice Input, was also a great find.
The only annoying part is that I now have to retrain my recommendations for HB, since OB unlike HB, offers no way to extract your settings, and I found no method to access the settings files in newer Android. Thankfully, since HB offers import/export, it will be the last time.
Here’s a tip for YouTube, than might come in handy.
In videos that have subtitles available, you can go to the bottom of the description and hit the Show Transcript button. It opens the transcript on the right, and you can search in it. The negatives are that it’s not always available, and when it is, and it’s automatically generated, it might be inaccurate/misspelled, especially for niche technical terms.
