Anvit: Local Agentic RAG

Anvit is a private, offline AI assistant that lets you chat with PDF and Word documents, get instant answers, and extract key insights, all without sending your data to any server. Whether you're studying, researching, or reviewing reports, it's the AI document reader that stays entirely on your phone.

Built with advanced agentic RAG, Anvit goes beyond simple document search. It breaks complex questions into focused steps, retrieves the most relevant passages across your files, and refines weak results before showing you an answer, so you get sharper, more reliable responses from your PDF and DOCX library.

No cloud. No tracking. No data collection. Your documents, questions, and conversations never leave your device.

Key Features

• 100% Offline AI — Gemma 4 (2B or 4B) runs locally through Google LiteRT. Once downloaded, the app works fully offline with no internet connection needed.

• Chat with PDFs & Word Documents — Ask questions across PDF and DOCX files and get answers grounded in the exact passages from your files.

• Agentic RAG Pipeline — Complex questions are automatically broken into focused sub-queries, retrieved across multiple passes, and refined before you see the answer.

• Hybrid Retrieval — Combines dense semantic search with BM25 keyword search. Finds what you mean, not just what you type — the best of both worlds for offline document search.

• Corrective RAG (CRAG) — When retrieval quality is poor, the app automatically re-queries with rephrased terms instead of hallucinating an answer.

• Multiple Document Collections — Organize your PDFs and Word files into named collections and query each independently.

• Cited Sources — Every answer includes the source document and the exact passages used — no guessing where the information came from.

Great for

• Students — Chat with textbooks, research papers, and lecture notes (PDF or Word). Get instant answers and summaries without rereading entire documents.

• Professionals — Review contracts, reports, and technical specifications faster with an offline AI document assistant that respects your confidentiality.

• Researchers — Query large archives of PDFs and DOCX files privately. Anvit handles multi-document reasoning without requiring a cloud subscription.

• Privacy-conscious users — Anyone who wants the power of an AI document summarizer and PDF chat without trusting their files to someone else's servers.

Anvit is proof that powerful, private AI is already in your pocket. Your phone is the cloud.
