As answered by people managing Diffyn and Tokvio.
Diffyn's answer
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
Tokvio's answer:
Most AI apps give you one AI and hope it is the right one for your question. Tokvio gives you all three of the best AIs — Claude, ChatGPT and Gemini — and automatically picks whichever one will give you the strongest answer.
One subscription instead of three.
Diffyn's answer
Diffyn is the platform that specializes on both change management and multi-model analysis.
Tokvio's answer:
Every other AI app locks you into one model. If that model gives you a bad answer you have no options.
Tokvio always gives you the best answer available because it has access to all three leading AIs and routes to whichever performs best for your specific question.
You also save money. Claude Pro, ChatGPT Plus and Gemini Advanced cost $60/month combined. Tokvio is $25/month for all three.

Diffyn's answer
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Tokvio's answer:
People who use AI tools regularly but are tired of managing multiple subscriptions and switching between apps trying to figure out which AI to ask for what.
Freelancers, small business owners, students and everyday people who want better AI answers without the complexity. Anyone who has ever thought "I wonder if Claude would answer this better than ChatGPT" — Tokvio answers that question for them automatically.
Diffyn's answer
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
Tokvio's answer:
I was paying for Claude, ChatGPT and Gemini separately and switching between three different tabs all day. Each AI was better at different things but I never knew which one to use for what.
I built Tokvio to solve that problem for myself and anyone else who felt the same way. One app, all three AIs, smart routing that figures out the best one automatically.
I built and launched it at 15 years old using Claude Code as my primary development tool.
