The gap Amberbird fills If you're on an H-1B, an F-1 visa with OPT, or working toward an employment-based green card, you know the choice: pay a lawyer $400 an hour for a question that might take five minutes to answer, or go searching Reddit and hope the loudest voice in the thread happens to be...

As answered by people managing Diffyn and Amberbird.
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.
Amberbird's answer:
Most AI immigration tools are built to always answer, and that confidence is exactly what makes them risky in a domain where a wrong answer can cost someone their status. Amberbird does two things differently: every claim it makes is tied to the specific USCIS source it came from, so you can verify it yourself, and it's built to recognize when a question depends on individual legal judgment and refuse to guess, referring you to a licensed attorney instead. The refusal is treated as a core, tested feature, not a fallback.
Diffyn's answer
Diffyn is the platform that specializes on both change management and multi-model analysis.
Amberbird's answer:
Right now the choice for most people is a $400-an-hour immigration lawyer or an anonymous forum thread, both of which have real downsides: one is expensive for a simple question, the other is free and occasionally catastrophic. Amberbird sits between them. It handles the clear, common questions with sourced, verifiable answers, so you're not paying attorney rates for something the government already published, and it's honest about the edge of its own competence instead of bluffing through the questions that genuinely need a human.

Diffyn's answer
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Amberbird's answer:
People navigating US immigration who have a question, not a case: international students on F-1/OPT status, H-1B visa holders and their employers, and individuals working toward an employment-based green card. Typically people who don't yet need to retain an attorney but can't find a reliable, fast answer anywhere else.
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.
Amberbird's answer:
It started from a simple observation: people on H-1B, F-1/OPT, or green card timelines carry a specific kind of 2am fear, a question like "does my OPT clock keep running if I leave the country?" where getting it wrong doesn't cost money, it costs years. The only options were an expensive lawyer or a confident stranger on a forum. Amberbird was built to close that gap with something in between: honest, sourced, and willing to say "this needs a lawyer" when that's the true answer.
