I got Brieferr because I like sentiment data. it is not DeepTalk, but it is not trying to be either. Brieferr is a tool for you to get insights from minimal data. You ask 2 questions, and you can ask them a million times (or however many times fit in a 1gb csv file) and then it plots out the sentiment using their ai/nlp algorithms.

I went and scraped a bunch of Amazon book reviews and used the title of the review for field 1 and the review for field 2. I did it on books I have read and I thought that brieferr got the sentiment from the reviews very accurate.

Pro/Con
-so this is both a pro and con-you can only put in two questions, but you also only have to put in two questions. It is hard to get people to fill things out so two questions is actually a pretty good idea. And you can fit that into any form/survey tool for desktop or mobile without making it look like you want the person to write you a book. Just "can I ask you two questions please?"
so some might see that as a limitation but it is also a strength.

Pros-
-Simple to use. Download the sample file and it has the following fields

Name
Email
What do you like best?
Do you have any suggestions?

You can replace the questions with your own, but I think you want them to be open ended and sentiment related. Like asking someone "what did you think about XYZ?" is a lot better than "What type of car do you drive?"

As for the name and email you can put anonymous into both fields. So you don't need to get that data, but you can. I haven't run it with email or names yet, and it doesn't need it for the sentiment measures. I suspect it has those fields because if you have a form on your website you also want to capture their email so the system lets you process the form output but only actually uses the two questions.

-good output. I like the charts and the info that each dashboard has. It can point you in the right directions of how your customers are liking/not liking your product and see s summarized version of what they are actually saying.

Cons-
-I don't have a lot really. I had one small issue but support got to it quickly and everything was fine. The tool does what it says it does and they have their roadmap as well so over time it will do even more. But in its current format it works just fine.

I like it. It probably won't completely blow your mind as to what your survey participants are saying, unless you are dense af, but it will show you what is actually being said and then show you specifically what they like/don't like as long as you ask good questions and get a decent number of responses back.

If you get lots of feedback, do lots of short surveys (2 questions), or want to try and figure out how much people like your product, then try out Brieferr. it is a solid and interesting tool that give you a quick view into peoples opinions about whatever you ask them.
