Questions & Answers

As answered by people managing heyEli.io and Diffyn.

What makes your product unique?

heyEli.io's answer

Eli is the first platform focused entirely on the parent — not the child — in the ADHD equation. Instead of clinical resources about ADHD itself, Eli gives parents ready-to-use tools: AI-generated school letters and word-for-word scripts for everyday ADHD parenting situations.

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.

Why should a person choose your product over its competitors?

heyEli.io's answer

Most ADHD resources are information-heavy but action-light. Eli skips the articles and gives you tools you can use in the moment — a letter ready to send to your child's teacher, or the exact words to say during a meltdown. It's also 100% free with no account required.

Diffyn is the platform that specializes on both change management and multi-model analysis.

What's the story behind your product?

heyEli.io's answer

Eli was built by a tech dad raising a child with ADHD. After struggling to find resources that actually helped in the moment — not just explain what ADHD is — he built the tool he wished existed.

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.
