Questions & Answers

As answered by people managing TankBud and Diffyn.

What makes your product unique?

TankBud's answer

TankBud connects tracking to care data. The catalog covers a growing list of 1,500+ fish, invertebrates and corals plus 300+ plants, with tank size, water parameters, temperament and tank mates for each. The stocking calculator checks a planned community against that data before you buy anything. Saved plans convert into live tanks with the same logs, reminders and photos.

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?

TankBud's answer

Most aquarium apps do logging or calculators, not both. TankBud ties them together, so the same care data behind the public catalog powers the stocking check in your plans and tanks. There's no cost for hobbyists. Paid plans exist for businesses that manage multiple tanks (fish stores, breeders, service companies with client tanks), and those come with a free trial.

Diffyn's answer:

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

Which are the primary technologies used for building your product?

TankBud's answer

Next.js and React with TypeScript, Postgres on Supabase, deployed on Railway. TankBud is an installable web app (PWA), so it runs in any modern browser and installs to a phone home screen without an app store.

Diffyn's answer:

React, Next.js, POSTGRESQL

How would you describe the primary audience of your product?

TankBud's answer

Freshwater and saltwater hobbyists, from one betta tank to a whole fishroom. People who want water tests, maintenance and stocking plans in one place instead of a spreadsheet. There's also a business tier for aquarium service companies, fish stores, breeders, and any other business that manages multiple tanks.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

TankBud's answer

I'm a long time aquarium hobbyist and a software engineer. I first built TankBud for my own tanks because my water tests, maintenance notes and stocking research were spread across a spreadsheet, a notes app and a pile of browser tabs. I worked on it for a couple of years and it's now officially released. The care catalog and stocking calculator are free for anyone to use, no account needed.

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.
