Yeah, that's totally fair, I just got overly excited.
Even just the total would be awesome. I don't mind entering metadata manually, and looking through a picture of the receipt for each line item if I need to do that, but I've love it to automatically capture the total so I can see those at a glance without manually inputting them. Maybe the date, too, but that's less important if I can just take the photo as soon as I get the receipt. (Getting the vendor would be doubly awesome, but I know that would be nearly impossible, so I wouldn't ever expect that.)
I wrote a web app to do this for myself when I was contracting, but I had to manually enter the vendor, total amount, and date for each receipt, which got really tedious. (The process wasn't fast enough that I would do it on the move, so I saved up receipts and did them in batches, which took a lot of time.) I'd love to just be able to take a picture and enter some metadata (probably just vendor and category) and have at least the total be pulled from the receipt, and the date either pulled or defaulted to today's date.
Yes, please let me know if you ever implement OCR! And feel free to contact me directly in general. My email is sasha1rus@gmail.com. In the meantime, I'm going to give this a try as-is. Thank you!
