As answered by people managing JSFiddle and Semuko.
Semuko's answer:
We respect our customers' privacy and do not publicly disclose customer names without their permission.
Semuko's answer:
Semuko combines an all-in-one CRM and business management platform with a deeply integrated AI assistant called Ask Semu.
Instead of using separate tools for client management, contracts, invoicing, payments, scheduling, workflows, communication, social media, and AI, Semuko brings those functions together in one connected platform.
Ask Semu is designed to make AI useful in the context of running an actual business—not just as a standalone chatbot. It gives creative professionals an intelligent assistant alongside the CRM tools and business information they already use every day.
Semuko also includes features such as:
The result is a modern, flexible platform designed to help creative professionals spend less time managing software and more time growing their businesses.
Semuko's answer:
Semuko is designed for businesses that want more than a traditional CRM.
While platforms such as HoneyBook, Dubsado, Bloom, and Studio Ninja focus primarily on client management and workflow tools, Semuko combines those core capabilities with Ask Semu, its built-in AI assistant, along with automation, live chat, embeddable booking and checkout, API access, social tools, POWERFUL mobile apps 📱, and agency-focused functionality.
Semuko is built to reduce the number of separate subscriptions and disconnected tools required to operate a creative business.
Users can manage:
All of this can be managed from one connected platform while using AI to help work more efficiently.
Semuko is also designed to grow with a business, from independent creatives to teams and agencies that need more advanced capabilities, integrations, white-label experiences, and greater flexibility.
Semuko's answer:
Semuko is built primarily for creative professionals, independent service businesses, growing teams, and agencies that manage clients, projects, bookings, and payments.
Its core audience includes:
Semuko is especially well suited for professionals who want to consolidate multiple business tools into one platform and use AI and automation to reduce administrative work as their business grows.
It works for solo professionals who need an easy way to manage their entire client journey, as well as larger teams and agencies that need advanced integrations, API access, team functionality, and branded client experiences.
Semuko's answer:
Semuko was created from nearly two decades of firsthand experience building software for creative professionals and understanding how they actually run their businesses.
Over the years, business software became increasingly fragmented. A creative professional might need one system for CRM, another for contracts and invoicing, another for scheduling, another for communication, another for social media, and now yet another tool for AI.
Semuko was built around a different idea:
Your business tools should work together.
The goal was to create a modern platform where the client journey, business operations, automation, communication, and artificial intelligence could live in one connected ecosystem.
That vision has evolved into Semuko today: an AI-powered CRM and business management platform centered around Ask Semu and designed specifically for creative professionals, service businesses, and agencies.
Semuko continues to be built around the same principle: give independent businesses powerful technology without forcing them to stitch together a dozen different platforms.
Semuko's answer:
Semuko is built primarily with modern web technologies. The platform also uses cloud-based APIs, integrations, and dedicated mobile applications.
Semuko uses a modern API-driven architecture designed to support automation, AI-powered functionality, real-time experiences, third-party integrations, and continued expansion of the Semuko ecosystem.

Test your javascript, CSS, HTML or coffeescript online with jsfiddle code editor. Jsfiddle – code playground.
JSFiddle cannot be used to host code on your server. The code has to be on JSFiddle and is public all the time.
What is missing from JSFiddle is live previews. You have to basically refresh the page by clicking on the play button. And compared to other playgrounds, JSFiddle is probably the slowest. Another slightly frustrating...
