NYTimes Spelling Bee Helper
This page will look at your hints screen and determine the lengths of the words that are left.

First upload screenshots of your hints page from the app, as well as the words that you have already entered. Image-to-text software (Tesseract) will convert your images into three text files. After uploading screenshots, click the edit buttons below to edit each file (clicking 'Save My Edits' each time), then hit the PROCESS button.

In the words list, make sure words are separated by spaces or new lines. Remove any junk entries.
In the two-letter list, check for 1 being mistaken for I and delete any garbage lines.
The lengths list must be entered manually, a fixed example is preloaded. It comes from the table in the hints screenshot, which will be displayed. Separate each number with a comma. The first line of the lengths list is the header, containing possible lengths. The next lines are the remaining rows of the table in your hints screen, for each letter, in order. (Note that the final column of your hints table, the totals, is not used.) An example of the lengths file could be:
4,5,6,8
0,1,1,0
1,1,0,1
2,1,1,0
