Seeing AI vs Envision AI vs KNFB reader

hello. i am considering whether to pay for envision ai or knfb reader or to stick with seeing ai. i am not very experienced with these apps so i can't foresee what i may need them for.
how would you describe the comparative advantages of these apps?



I think there are podcast on each in the applevis. I have Seeing AI and it good. Also because it is from Microsoft, I know it will not just disappear one day. The only issue is that the app affects the battery.


I've used all three quite a bit. Seeing AI is free, and pretty robust in what it can do. KNFB reader is great if you're reading paper documents, but only that really. It's fast and you can do Offline OCR so it's a bit more secure. Beyond that though it's not at all worth the money I feel. It's outdated and these days, a bit cumbersome to use. ENvision is my favorite. I find it's a bit more accurate than Seeing AI, even though the two apps have similar capabilities. Envision's also nice in that it recognizes print and handwriting without switching to a separate area of the app. If you care, Envision also has a magnifier. I'd try a trial run of Envision and see what you think. I'd avoid KNFB reader though. Even if you scan multi-page documents, there are apps that are way, way cheeper which work better even for that. I've heard good things about Voice Dream Scanner for instance.

In general, I don't do a whole lot of document scanning, but when I do, the only advantage I've found to KNFB Reader over Seeing AI is PDF extraction. I don't believe Seeing AI can extract text from image based PDF documents.

Other apps might do this better and/or cheeper, but like I said, I only do PDF image scanning occasionally. For other purposes, Seeing AI suits my needs quite well.


I wanted to experiment with Seeing AI and downloaded it few days ago.
I found the app great but somehow, the battery drain is really quick in it.
I remember using it at around 90% battery power but when I closed the app it dropped to around 50.
I could never understand why so I deleted the app.

I use Seeing AI quite often. However, if I want to scan a document that I may wish to potentially keep I use Voice Dream Scanner. It is so much cheaper than KNFB Reader and seems to work much better. Also, if you have other Voice Dream products, the voices you have can be used with all of their products and, IMHO, are much better and more pleasant to listen to. This is not a knock on KNFB Reader, but I have had much better luck with Voice Dream.


Try a month just in case you do not care. If you like it them do the other.

Stick with a monthly

It's definetly best to stick with monthly at first. ALso, they had an amazing summer sale last year, so if you do decide you like the app and want to get lifetime, and they do another one, then, it'll be quite a bit cheaper. I have no idea if they will actually do that again though.

seeing Ai.

Hey. I've used Seeing Ai. and I love it! Because it's free, and it's more descriptive with images & text in images.
Also, you can browse your photo library right from the app! Which means photos can be analyzed & you can share them & then delete them if you wish. You can create a siri shortcut to browse photos, or just open the app, go to the menu & double-tap on browse photos. Also, if I do need to scan a doc, you'll get guidance as you scan. Go with Seeing Ai. & fohget the other ones. I think they're overpriced. But that's just the cheap skate in me talking. Seriously though, I think for a free app, you get a ton of features! I will say this though. While I have Seeing Ai. as my primary use app, I do have other Ocr. apps on my ipad. And I think every app has it's strong & weak points. Plus if 1 app isn't working, then you have another 1 or 2 or more as your fallback options. But if you want my opinion, go with Seeing Ai. & you will not regret it. Hope this helps. And sorry if this seems long-winded.

Seeing AI and VoiceDream Scanner

I use both Seeing AI and VoiceDream Scanner heavily. Seeing AI is great for many tasks but it is neither private enough or quite good enough for some document scanning. VoiceDream Scanner is great for document capture and also for those extremely sensitive things like identifying a certain credit card. KNFB Reader might as well be dead, because it's expensive and I don't know of a single job it has done better than VoiceDream Scanner. I've tested because I bought it when it first came out. Seeing AI's short text reading captures all kinds of things that don't work well with document scanners, and I love the convenience of the Siri integration.. Of these 2 apps I really can't say which I love more, so it's good we don't have to choose only one tool.

One More Vote for Seeing AI

First off, let me say that Seeing AI and Soundscape are currently the only scanning apps on my phone. I don't currently have enough on my iTunes gift card to get any of the commercial apps, but my birthday is coming up later this month so hopefully that will change. I've heard and read good things about all these apps, and wish to try others out. I read a little while back that the next version of KNFB Reader was in beta, and that it would be made a part of their Newsline app. Does anyone know if this is still the case and if so, will the expanded app still be free? I've got the Newsline app and really like it. Haven't used it much though yet. But back to Seeing AI. I have it and love it. I'm a bit confused though by the lighting as it relates to the various channels excepting of course the Light channel itself. That one plays a tone, so I find that kinda nice. I've scanned several things by myself and with the help of sighted people, and the app seems very impressive. I was talking with one of my tutors this morning about the app. She is fully sighted and recently took it for a spin, and she's very impressed as well. She took a picture of another staff member who works here.

KNFB reader

The NFB newsline app is still in beta with the KNFB reader integrated into it. I personally don’t use the KNFB reader part of the app because I find seeing AI, voice dream scanner, and the app simply called Voice, to be faster, easier to use, and yield better results.

I regret purchasing KN F

I regret purchasing KN F reader and wish I knew about seeing AI before having purchased it or about voice dream scanner... KNFB reader was so expensive and I've maybe used it twice and did not like the results. Feel like I just threw away money I could've spent on something more useful...

Voice stream scanner VS voice?

Can anyone compare voice Dream scanner and Voice? I understand that KNFB reader can recognize when you turn the page when scanning multiple pages. Can either voice Dream scanner or Voice do this? Can either scan two facing pages of a book?
