Formal Brief

"Pursuant to the holdings in Morrison v. Olson, 487 U.S. 654 (1988), the constitutional framework demands careful consideration of the separation of powers..."

Assertive Argument

"The defendant's own documents contradict this testimony. Exhibit 47 shows exactly what they knew — and when they knew it."

Technical Precision

"Section 12(b)(6) requires plausibility, not probability. Plaintiff's complaint satisfies this standard at ¶¶ 23-31, 45-48."

How It Works

Three steps to privacy-first legal research

Load the AI

The model downloads once (~1GB) to your browser cache. After that, it loads locally in seconds — no internet required.

Add Your Documents

Upload PDFs and text files. They're indexed in your browser memory — never uploaded to any server.

Research & Draft

Ask questions, search cases, or draft arguments. The agent searches, validates citations, and writes in your voice.
