Problem → solution
Private files should not need a cloud vault.
Contracts, receipts, notes, and screenshots pile up across folders and chats. Most AI document tools ask you to upload sensitive files to someone else’s servers. Bruq AI keeps the archive local: index on the phone, retrieve snippets, then optionally phrase an answer with an AI key you configure yourself.
Private vault
Documents and the index live on your device — not an Influrion cloud drive.
On-device index
OCR, chunking, and embeddings run locally until files show Ready.
Cited answers
Ask in plain language and verify every claim against source snippets.
Features
Built for a vault you can trust.
Ask your vault
Chat in plain language or run hybrid, semantic, or keyword search. Answers can include Verified Sources citations.
Grounded answers with citations
Open reference text and the original file. If the vault context is not enough, Bruq AI is instructed to say it does not know.
On-device indexing
Import → extract (PDF text or OCR) → chunk → embed locally until items show Ready. Processing status stays visible.
Folder discovery & auto-recognition
Browse device media like a library, batch-import with triage, and optionally watch Downloads, Documents, and Pictures.
Device lock + BYOK AI
Unlock with the phone’s PIN, pattern, fingerprint, or face. Groq and OpenRouter keys stay on device — no Influrion-hosted keys.
Inside the app
Vault, Ask, folders, and settings.
A calm Private Archive interface — parchment surfaces, ink navy type, brass accents — with a friendly vault mascot.
How it works
Import → index on device → ask & verify.
Import
Pick PDFs and images, or let Bruq AI find them on your Android device. Optional auto-recognition keeps the vault growing.
Index on device
Text extraction, OCR, chunking, and embeddings run locally until files are Ready in your private vault index.
Ask & verify
Search or chat over your vault, then open citations to confirm answers against the source snippets and originals.
Privacy
What stays local vs what leaves the device.
Stays on your phone
- Original PDFs and images in your vault
- OCR / PDF text extraction, chunking, and embeddings
- Local SQLite index (keyword + vector search)
- API keys stored on device
- Vault unlock via the phone’s built-in lock
Only when you ask with AI configured
- Your question plus retrieved text snippets
- Sent to the provider you chose (Groq primary, OpenRouter fallback)
- Not used to sync or host your full vault at Influrion
- Search still works against the local index without chat

On Android you may need to allow installs from this browser. Your vault stays on-device after install.
FAQ
Questions about Bruq AI.
What is Bruq AI?
Bruq AI is a privacy-first Android knowledge vault by Influrion Solutions. It turns PDFs and images on your phone into a searchable on-device archive you can ask in plain language, with cited answers. It was formerly known as BrainVault.
Is my vault uploaded to Influrion?
No. Documents and the local index stay on your device. Influrion does not host your vault.
What leaves the phone when I ask a question?
When an AI provider is configured, retrieved text snippets plus your question are sent to that provider to generate the answer. OCR, chunking, and embeddings run on-device.
Do I need an API key for Bruq AI?
Yes for AI chat answers — configure Groq and/or OpenRouter (bring your own key). Search over your vault still uses the local index.
What file types does Bruq AI support?
PDFs and images (with on-device OCR). Optional smart photo filtering can skip personal photos during auto-recognition.

Is Bruq AI available on iOS?
Android is the shipping focus today (package com.bruq.ai). iOS identifiers exist in the project; Influrion will announce availability when a store build ships.
