Why not just use ChatGPT for your union contract?
Because general tools draw on the open internet and will answer anything (invented if needed) with no citation and no accountability. AviChat is built only on your collective agreement, cites the article and section on every answer, and declines questions the contract doesn't cover.
General tools are good at general things. Your collective agreement is not a general thing.

What general tools do better
To be fair: for general knowledge, quick answers on non-contract questions, and everyday writing tasks, tools like ChatGPT are genuinely useful, and faster than anything purpose-built. If a member wants a recipe, a cover letter, or the capital of Portugal, they should use one. AviChat does one thing: your collective agreement, answered with its own words and a citation. That narrowness is the point.
"So does a contract tool replace the steward?"
It's the question that follows this one almost every time, and it deserves more than a row in a comparison table. The short version: a tool like this handles lookup work — finding what article 14.3 actually says — and judgment work stays exactly where it was. Full answer here, including what unions are winning in AI contract language and six questions worth asking about any tool put in front of your local.
