I actually had good results with the free plan but with strong edit limitations (which I explicitly prompt for). Its the same underlying models as cursor (claude 4 is by far the best) and I find it a little easier to use because it takes up the full screen and is less eager than cursor somehow.
This has been an interest of mine for quite a while.
Right now the most relevant mapping process I have to do is taking Amazon product data and transforming it to a Shopify upload csv.
The largest of these is around 20k rows, so nothing crazy.
There are apps that do this via APIs, but at a large enough scale, they are not reliable.
The process takes around 10 hours, with the help of a VA who does the lower level cleaning stuff.
I made a bare bones spreadsheet with under 10 columns, which makes it much easier to work with the data.
Once I'm satisfied, I run it through a python script, which turns it into a Shopify conforming csv.
Because of different needs of clients, I almost always have to modify the script, but less and less each time, and Cursor makes the edits pretty easy, as long as I review each proposed change and prevent it from getting the script.
Good thing about cursor is that it can run its own tests against the input csv in agent mode and debug autonomously.
This is true, but at some point the community will figure out what's going on, and either leave to a more promising and uncompromised project, or find a way to limit the voting power of the attacker. You can see this happening now with the Curve Wars.
