There is an astonishing level of hype on the Braigo Labs website. However, that's not really a fair comment, as I haven't tried the product yet. If I can ever find my way through the self-promotion to figure out exactly what's on offer, I'll give it a shot and let everyone know.

Edit: So, OK. There's a register link near the top of the page. In short, the service lets you upload images in various formats, and have OCR done on them. So sort of a cloud Kurzwiel or KNFB, if you will. But free. One nice feature is that it can pull images from your dropbox and OCR them, making uploads easier. On the random screenshot I pulled off Reddit (apparently it's a screenshot of someone's phone, and the phone is displaying a weather alert from Environment Canada), the OCR it provided wasn't quite as good as $1. Also, by default, anything you upload is public, and will be associated with your real name/email address.

For the sighted folks, $1 is my test image.

The OCR results from $1 are:

Braigo gives me the following results:
> [«000 ROGERS ‘3 9:04 PM 1 ’0‘ )3 47% E]-, weather.gc.ca, Statements, 6:11 PM EDT Sunday 14 August 2016, Special weather statement in effect for:, o Newmarket — Georgina — Northern York, Region, 0 Pickering — Oshawa — Southern Durham, Region, 0 Uxbridge — Beaverton — Northern Durham, Region, 0 Vaughan — Richmond Hill — Markham, O, ‘A rare weather event expected for southern ., Ontario on Tuesday: a rainy day., Most people have heard the expression, "when, it rains, it pours". lt loosely means, when, something happens it can happen repeatedly, thereafter., Following what may be the most significant, summer rainfall for many locales in southern, Ontario yesterday, that expression may be on, peoples' lips again on Tuesday. A slow—moving, low pressure system over eastern Texas is, forecast to drift northwards over the next couple, of days reaching the lower Great Lakes on, ]

So I think I'll be sticking with OCR Space for now.

Edit to add: OCR results from Braigo and tesseract are identical. Looks like that's the OCR library they're using. Also, captionbot says "I think this is a screenshot of a building." Uh, no.
