Chat with any PDF, video, or website and get cited answers in seconds
Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.

Answers drawn from roughly 25,000 manuals spanning more than 85 brands, covering boilers, heat pumps, air conditioning, ventilation, charging points, solar panels and inverters.
Look up error codes, check parameter and settings values, and identify the exact part number needed, instead of digging through portal PDFs.
Every response carries the original technical source and page reference, so technicians can verify the advice before acting on it.
Manuel indexes past work orders, internal documents, technician tips and previously solved faults alongside manufacturer data.
