Ask Your Documents Anything
Free · In-App Purchases · Designed for iPad
Offline RAG. Ask your documents anything - get cited answers in seconds. No cloud, no accounts, just dump, query, and watch the magic happen.
Your documents. Your questions. Answers that cite their sources.
Stop digging through PDFs. OpenIntelligence brings research-grade retrieval to your iPhone - the same techniques powering enterprise AI search, running entirely on your device.
12 ADVANCED RAG TECHNIQUES. ZERO CLOUD DEPENDENCY.
This isn't keyword search. OpenIntelligence uses a full retrieval-augmented generation pipeline:
• HyDE (Hypothetical Document Embeddings) — Bridges vocabulary gaps between your question and the answer
• Hybrid Search — BM25 keyword matching fused with 384-dim neural embeddings
• Reciprocal Rank Fusion — Merges multiple retrieval strategies for better recall
• MMR Diversification — Reduces redundant results, surfaces broader context
• Cross-Encoder Reranking — Neural model re-scores every candidate for precision
• Parent Document Retrieval — Expands matches to include surrounding paragraphs
• Contextual Compression — Strips irrelevant sentences, keeps only what matters
• Lost-in-Middle Mitigation — Reorders context so the AI attends to key passages
• Query Rewriting — Clarifies ambiguous questions before retrieval
• Semantic Chunking — Splits documents at natural boundaries, not arbitrary limits
• Multi-Column OCR — Correctly reads complex PDF layouts at 360 DPI
• Agentic Tool Use — AI calls search, summarize, and compare tools autonomously
THE RESULT?
Ask "What oil does my car take?" and get "SAE 0W-20 synthetic, 5.3 quarts" - with a citation you can tap to verify.
DEEP THINK MODE
Standard mode answers in seconds. Deep Think spawns multiple reasoning sessions, cross-validates evidence, and synthesizes a thorough response. Perfect for research, legal review, or technical documentation.
