As answered by people managing JSFiddle and The Reflection.
The Reflection's answer:
The Reflection works with corporate training and sales enablement teams across FMCG, pharmaceutical, retail, IT, financial services, engineering, and manufacturing sectors. Deployed globally, with active teams across the UK, Europe, Middle East, and emerging markets — supporting practice sessions in more than 15 languages. Client details are available upon request.
The Reflection's answer:
The Reflection is scenario-agnostic — any conversation, any role, any industry. Most AI roleplay platforms are built around SDR cold calls or scripted sales pitches. The Reflection covers the full range of workplace conversations that actually drive business outcomes: face-to-face field sales meetings, leadership feedback sessions, performance reviews, difficult conversations, and frontline customer interactions. Fully customizable scenarios, no rigid templates, no VR infrastructure required. Deploy in days, not months.
The Reflection's answer:
Customization depth is a key reason clients choose it: scenarios reflect your actual products, your actual objections, your actual brand language. Clients report 28% uplift in sales performance and 2× faster time-to-productivity during onboarding.
The Reflection's answer:
L&D managers, Sales Enablement leaders, and HR teams in mid-market and enterprise companies. Strong adoption in field sales (pharma, FMCG, medical devices), leadership development programs, and frontline teams in retail, hospitality, and healthcare.
The Reflection's answer:
The Reflection was founded by Petr Kanaev, who spent over 15 years leading Learning & Development at Mars Incorporated — managing training programs for thousands of employees. That experience made one thing clear: most corporate training builds knowledge, but rarely changes behavior. The gap between knowing something and actually being able to do it in a real conversation is where most L&D investment gets lost. The Reflection was built to close that gap — a practice-first platform that moves teams from knowledge to genuine skill, through realistic, repeatable conversation simulations. Everything in the platform reflects what actually works in large-scale corporate training.
The Reflection's answer:
The Reflection is built on large language models combined with RAG (Retrieval-Augmented Generation) technology — meaning AI characters in every simulation are trained on your company's actual knowledge base: products, pricing, objections, sales methodology, brand standards. Practice sessions aren't generic roleplay — they reflect your specific business reality. On top of that, the platform includes a proprietary feedback system delivered directly on the video timeline. Reviewers and managers can leave precise, timestamped comments at the exact moment in a conversation where something happened — rather than general post-session notes. This approach has shown 40% faster skill acquisition compared to standard AI roleplay platforms. The result is the most customizable AI roleplay platform available for corporate sales and leadership training — fully adaptable to your company's language, scenarios, and standards, without any vendor dependency.

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...
