It is very important for us because otherwise, we need to do it again. Also, the collaboration between the team and our clients are way more seamless in the tool with the review and q&a features. ### 9. Great service, good product **Rating:** 4.5/5.0 stars **Reviewed by:** Robbert R. | Small-Business (50 or fewer emp.) **Reviewed Date:** February 15, 2023 **What do you like best about Kili?** Kili stands out in its customer service. They provide great help with onboarding and provide the right resources for setting up your first projects. When one of our team mates has a question, the reply from kili is always fast and helpful. They are very open to new feedback and that is always great to see. Furthermore, they provided us with some help getting acquainted with the quality assurance tools they have. The product itself is also pretty nice to use. Labeling is fast, and the experience is quite customizable with plenty of options for each project and keyboard shortcuts to make the experience fast. **What do you dislike about Kili?** The platform looks great, and serves our needs, but some features are missing. One of the features we would have liked to see is regarding text annotation projects in images. Right now, we need to upload OCR data with the image (for which kili provided a tutorial) but it would have been great if this is done automatically. **What problems is Kili solving and how is that benefiting you?** Kilii is helping us label data faster than before. This is for two reasons: smoother labeling experience, and easy collaboration between labelers. Another issue kili is helping us with is higher quality data: The reason is twofold.

I used the platform to label and tag images, and I found it so easy and efficient, the best labeler I have used so far. Its integrations using its API make it just better. Another point I want to mention is the helpful community and staff, I joined their slack server, and they helped other users and me with complete dedication. **What do you dislike about Kili?** I honestly find the bugs/breakage of elements in Kili a bit annoying. I understand it's new, so it'll be perfect if they get fixed up! There are some general issues with the dashboard, like sometimes login doesn't work correctly, or there might be some issue with cookies that prevent me from accessing the website. A workaround I found was to use incognito until the staff fixes the issue. **What problems is Kili solving and how is that benefiting you?** Kili is making it very user-friendly to tag and label all kinds of data.
