ParancU

Find the evidence in your documents.

ParancU lets you import PDFs, paste text, scan pages or use images, then ask questions and inspect the passages most relevant to what you are looking for.

Rather than hiding retrieval behind a generated answer, ParancU keeps the underlying evidence visible and lets you explore multiple candidate passages.

Multilingual retrieval and an adjustable semantic-lexical balance help connect questions to answer-bearing passages across different kinds of documents.

Local-first architecture

Corpus persistence, multilingual E5 embedding, semantic-lexical scoring, ranking and evidence inspection operate on-device. During corpus preparation, ParancU currently uses a constrained OpenAI API step to generate a short summary and one guiding question for each source chunk.
