We've been using Rasa ever since we started LimeChat. The HumanFirst <> Rasa integration allowed us to continuously improve our projects with conversational data generated from our deployed bots. We now ship projects and improve existing ones in record time.
Nikhil Gupta
Co-founder, LimeChat
Having been in the IVR space for over 10 years, developing an intent catalog from historical conversational data was painful and required a lot of manual efforts. HumanFirst is introducing an approach and tooling that makes this activity way more efficient and scalable.

Yves Normandin
CEO, Nu Echo
Having more than 1000 intents with 100+ utterances on average, we were finding it difficult (if not almost impossible!) to manage via Excel. The HumanFirst platform has helped efficiently maintain and organize our intents at scale as well as made it easier for our data annotator to edit them, data scientists to build models on them and provide transparency to our business stakeholders.

HumanFirst Studio seems to streamline a lot of the development process of a chatbot. I may have a look at getting premium access.

Cristina Santamarina

Manager at

I have been wanting something like this since I started working with conversational interfaces. This is something a lot of my previous customers have missed: a way for non-technical people to manage conversational training at scale. Now I have somewhere to send them.

Shivani Gupta

Quite useful for the kind of work I was doing. Would save a lot of time in pre-modeling efforts.
