You remember reading it \u2014 the exact point you need is somewhere<\/em> in your documents. But when you search for it, keyword search comes up empty, because the book didn’t use your words. You typed “how is light turned into energy,” and the textbook said “the light-dependent reactions convert light energy into chemical energy.” Same idea, zero matching keywords, no result.<\/p>\n

learn-me.ai’s Search<\/strong> works differently. It’s semantic search across your knowledge bases<\/strong> \u2014 it finds passages by meaning<\/em>, not just matching words. Ask in plain language and it surfaces the exact passage you were thinking of, even when the wording is completely different.<\/p>\n

Semantic Search: ask in plain language, get the exact passage \u2014 with source, page, and a relevance score.<\/figcaption><\/figure>\n

Search by meaning, not keywords<\/h2>\n

Type a question or a phrase the way you’d actually say it. Behind the scenes, Search reads the intent<\/em> of your query and matches it against the meaning of every passage in your sources \u2014 a hybrid of vector (semantic) and keyword search. So a query like “how is light turned into energy?”<\/em> pulls back:<\/p>\n

“In the light-dependent reactions, chlorophyll absorbs photons and converts light energy into chemical energy<\/strong> stored as ATP and NADPH\u2026”<\/p>\n

No exact words in common \u2014 but it’s exactly the passage you wanted.<\/p>\n

Every result is a real, cited passage<\/h2>\n

You don’t get a vague list of files \u2014 you get the actual ranked passages<\/strong>, each with:<\/p>\n
