I have a license for Devonthink Pro. It has strong AI capabilities. I don't think much of their customer service but, the software is still pretty robust. However, it is not the same as Freeter. It is not a question of what is more powerful as DevonThink would win easily. It is about what works effectively and simply. DT wants you to work in it’s environment alone. TaskPaper is not complicated, but it works very well. Freeter is also pretty simple to use. I don't have to worry about updating an index like DT does and I don't have to wrap my brain about how DT does things as it likes to use it's own built in text and browser tools.
I want to support the file structure I already have in place on my drive. And yes, DT will allow indexing too but again, this is not a comparison. Freeter is a dashboard and a pretty handy one at that. DT is great for complex comparisons of content using their AI. But I am merely trying to stay on top of various projects. I posted a link to Freeter, check it out if you like. Without getting married to the whole DT way of doing things, Freeter allows me a lot of freedom, peace of mind, and finally at the end of the day, success.
And no, I am not finding Freeters notes field of too much use yet. You can't print from them and you have to manually select all the text to copy out of them. I do keep some things in Freeters notes and todos, but I am still learning to do things this way. All my Freeter projects have a file launch button to my TaskPaper document. I find it much better to keep my progress notes in the same place (TaskPaper).
In case it helps, here is a screen shot of what this typically looks like. Freeter is behind my TaskPaper Dark theme document. Clicking on that lower left button in Freeter launched my TaskPaper file. Clicking the one beside it opens the .less file.
Each project is from the pull down menu on the upper left and each project has a TaskPaper launch button in the same place. IT seems to fit quite well for my purposes. I am still trying to track overall progress locally in Freeter but like I was saying, I am still new to all of this.
