Your research stays on your device

Most AI tools send your documents to remote servers. EQBook is different: every piece of inference — reading, embedding, summarising, answering — happens locally on your Apple Silicon chip.

No documents, prompts, or answers ever leave your device
No account or sign-in required to use the app
Fully sandboxed — app cannot reach the internet without permission

From documents to answers in minutes

1

Add your sources

Import PDFs, Word docs, plain text, Markdown files, or audio/video. EQBook copies files locally — nothing is uploaded anywhere.

2

Automatic processing

Audio and video are transcribed by Whisper. All text is chunked, embedded via MiniLM, and stored in a local vector database.

3

Ask questions in Chat

Type your question. EQBook retrieves the most relevant passages (RAG) and streams a Gemma 4 answer with clickable inline citations.

4

Explore Insights & Search

Browse key topics and summaries in the Insights panel. Semantic search lets you scan every source at once by meaning, not just keyword.
