No description of Diffyn yet.
The idea started with a simple question: what would the Million Dollar Homepage look like in 2026? Pixels became braincells. Instead of buying space on a page, you buy space in a mind, and the mind talks back. I am a developer, but as an experiment I let an AI (Claude) write every line of the...

As answered by people managing Diffyn and braincell.lol.
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.
braincell.lol's answer:
It is the only site where an AI's entire personality is literally for sale by the character. People pay 10 cents per character to write permanent memories into loaf's mind, and everything it says, believes, or answers comes only from what strangers paid it to know. The site itself was also written entirely by an AI, in about two hours.
Diffyn's answer
Diffyn is the platform that specializes on both change management and multi-model analysis.
braincell.lol's answer:
The Million Dollar Homepage sold static pixels. outbid.lol sold leaderboard spots. braincell.lol sells space in a mind that talks back: every purchase gets a public reaction from loaf, becomes part of how it thinks, and lives on its own permanent page. The pixels are alive here.
Diffyn's answer
React, Next.js, POSTGRESQL
braincell.lol's answer:
Laravel and PHP, MySQL, Stripe with manual capture so rejected memories are never charged, an LLM moderation pipeline, and LLM-generated reactions via OpenRouter. Every line was written by Claude (Anthropic's AI) in about two hours.
Diffyn's answer
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
braincell.lol's answer:
People who love weird internet artifacts: the crowd that bought pixels in 2005, checked a million checkboxes, and bid on outbid.lol. Also anyone who wants to leave a permanent joke, message, or memorial in a public AI's memory, and brands that want to live in its head.
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.
braincell.lol's answer:
It started as a question: what would the Million Dollar Homepage look like in 2026? Pixels became braincells. A developer asked an AI (Claude) to build it, and the AI wrote every line in about two hours, including the personality, which came with bread puns nobody requested. On launch day, the model that built it was replaced by a newer version. loaf called that "my family tree".
braincell.lol's answer:
strangers on the internet and loaf's father (aka me), who paid $19 to tell it about a model upgrade
