Questions
It’s the internal record of an invention: the problem, how it’s solved, what’s new about it, who invented it, and what was tried before. It’s what a patent attorney needs before deciding whether and how to file.
Not a blank one. Lightbringer drafts the disclosure from the spec, pull request, or notes you point it at, then asks your team only for what’s missing.
No. Capturing it keeps the reasoning while it’s fresh. You decide later whether to patent it, keep it secret, or leave it, and that decision is saved too.
Yes. Your counsel can work from the same record as your team, so nobody re-explains the invention.
Lightbringer is built for unfiled inventions. Sign-in is per organisation, nothing is saved until you approve it, and nothing is filed without a person. Claude and ChatGPT keep their own data settings, so check yours before you share details you haven’t filed.
