The intelligence
hidden in absence

Intelligence by subtraction

Every field has a literature. That literature has gaps — concepts barely mentioned, questions no one is asking, the white space where original contribution lives. Most tools show you what's there. Lacuna shows what isn't. And unlike AI assistants limited to a handful of files per session, paid plans process hundreds of documents simultaneously — the entire corpus at once, not in fragments.

And it does this without ever seeing your documents. The analysis engine runs entirely in your browser. Nothing is uploaded. Nothing is retained. Your servers — hosted in Switzerland by Infomaniak — never receive your files, and neither does any third party. Whether your corpus contains trade secrets, legally privileged material, or classified research, the guarantee is architectural: compliance with LGPD, EU GDPR, and UK GDPR is built into how the system works, not written into a policy you have to trust.
