CivBot Revolutionizes Support Stack
We all love CivBot (powered by GPT-trainer) over here - there's no way we
could manage without him… We've embedded him directly into the Support
stack, trying to get people to move away from going straight to
Freshdesk/Featurebase or hitting the support@, and it has been quite
successful.

Asynchronous Communication Made Easy
We are using the bots as a way for employees to retrieve policies and
procedures for our organization. We are 24/7 and 365 so we have
asynchronous communication needs. The ability to draw from a
policy/procedure and then provide an answer is awesome. We also have to
recall lots of information in the form of procedures. The Bots we built allow us
to retrieve this info quickly and to trust the answer. The ability to cite the
document retrieval is appreciated. Ground truth is important in our business.

Accurate and Reliable GPT-Based Product
I've tried many products based on gpt: afforai, orimon, gpt4 with plugin, I've
tried deploying each one of these, they don't work as this one.
This one provides accurate, useful and sourced information - in a clean way.
On a technical level, there are no quirks or bugs that have seen.
I'm confident this is the product that will stay, and work for most
applications, especially in actual work environment. I've deployed it
successfully in my business.

Perfect fit for 1/10 the price
My colleagues and I have been very impressed with GPT-trainer so far. It's really easy to get started;
there are good templates that gave us a solid starting point for our chatbot.
Integration into our website took literally 120 seconds. Maintenance and administration are hassle-free.

Game-Changer for Complex Methodologies
GPT-trainer’s bots have been a game-changer for us and our clients, guiding
us through complex methodologies like First Principles, FDA Design Control
methods and phases, and Lean Six Sigma with ease. Their solution not only
reduces confusion but also enhances the accuracy of our problem-solving
processes - we have seen no hallucinations to date. The app's multiple
text/document retrieval options are incredibly helpful. We're thoroughly
impressed with the product's capabilities and eagerly anticipate future
enhancements.

Improved Customer Service Efficiency
The project, initiated in June 2023, with the deployment of the bot and GPT-
trainer's conversational AI platform, led to substantial improvements in our
customer service efficiency. We felt the impact within a week. The vast
majority of issues are resolved completely autonomously. This immediately
freed up our team to focus on more important tasks.

Thanks to this tool!
Ìt is easy today to create and train quickly one's own chat bot. It is a complete tool that can make the data collection,
the structuration and much more. More than simple chat bot, you can use this too to set up your own Ai for different and complex task.
All you need is to have the data to be used and GPT trainer itself can help in gathering those data
