Three steps

Upload locally, ask, get a verified answer

01

Upload — on your device

Your filing is parsed, chunked, and embedded in the browser. No server sees the file.

02

Ask in plain English

A router sends explanatory questions to an on-device model, and number questions to a verified cloud tier.

03

Read a checkable answer

Every answer carries citations you can click, a confidence pill, and a provenance badge.

Why trust it

The privacy and the proof are the product

🔒 Your document stays home

Parsing and embeddings happen in your browser. We store only your email and a daily usage counter — never document text.

🧮 The model never does the math

The model proposes an arithmetic expression; a deterministic sandbox computes it. A hallucinated number physically can't reach you.

📎 Open citations, honest confidence

Answers cite the exact excerpt and show a confidence pill. Low-confidence answers are flagged, never dressed up.
