A secure, 100% local word processor and contract editor. Index your company's playbook and get compliance flags inline as you draft, generate Aggressive, Balanced, or Friendly clause alternatives with local Gemma models, redline counterproposals clause by clause, and export clean DOCX — all on your Apple Silicon GPU. No upload, no account, no cloud. A drafting room for agreements that can't leave the building.
Silo Systems builds infrastructure for people who would rather not negotiate with their own software. SiloDraft is the same discipline, pointed at one job — turning a counterparty's paper into a signed agreement that holds your positions — done entirely on the machine you already own. Your unsigned deal never becomes someone else's training data, and your negotiation playbook never lives on someone else's server.
Drafting, playbook indexing, compliance checks, clause generation, redline compares, and OCR all run on your Mac through a bundled local runtime on your Apple Silicon GPU. The Gemma model weights download once from Hugging Face or ModelScope, then SiloDraft works offline for the lifetime of the app — your drafts, trade secrets, and client agreements never touch a server.
Index your company's drafting guidelines once and SiloDraft holds every clause against them. Retrieval runs locally over SQLite FTS5 with reciprocal rank fusion — as you draft or edit, non-compliant clauses like off-policy liability caps or the wrong governing law are flagged inline, with the relevant playbook position right beside the text.
SiloDraft's compliance flags, risk analysis, and generated clauses are informational drafting assistance only — not legal advice, and no attorney-client relationship is created by using the app. It accelerates your drafting; it does not replace your judgement or your attorney. Every flag is a prompt to look, not a verdict.
Write in a rich-text drafting canvas with a negotiation sidebar that keeps flags, playbook positions, and alternatives in view. Start from a blank page, paste in a counterparty's Word file, or import a scanned PDF — on-device Apple Vision OCR turns image-based contracts into editable text without an upload.
Index your company's drafting guidelines once — retrieval runs locally over SQLite FTS5 with reciprocal rank fusion. As you draft or edit, SiloDraft flags non-compliant clauses inline: a liability cap below policy, the wrong governing law, a missing carve-out — each flag informational drafting assistance, with the playbook position attached so you decide.
Select a clause and generate Aggressive, Balanced, or Friendly alternatives with local Gemma models through mlx-lm — offline, on your own GPU. Compare the counterparty's counterproposal side-by-side with clause-level diffs and risk analysis, then ship a clean DOCX, Markdown, or annotated risk-summary PDF in one click. Nothing in the deal ever leaves the machine.
Index your company's drafting guidelines and SiloDraft checks every clause against them as you type — liability limits, governing law, indemnities — flagging deviations inline with the playbook position attached.
Select any clause and generate drafting alternatives — Aggressive, Balanced, or Friendly — offline, using local Gemma models through mlx-lm on your Apple Silicon GPU. No prompt ever leaves the machine.
Compare a counter-party counterproposal against your draft side-by-side, clause by clause, with clear visual diffs and risk analysis — so you see exactly what moved and what it costs you.
Import scanned PDFs and image-based contracts using on-device Apple Vision OCR. The paper agreement someone faxed in 2009 becomes editable, searchable text without ever being uploaded.
A rich-text editor built for contracts: inline risk highlights directly in the text and a negotiation sidebar that keeps flags, playbook positions, and clause alternatives one glance away.
Export a clean DOCX for opposing counsel, Markdown for your own records, or an annotated risk-summary PDF report for the deal team — to a folder you choose, never to a server.
The Gemma model weights download once from Hugging Face or ModelScope with live progress. After that, every compliance check, clause draft, and redline compare is fully offline.
A SwiftUI host boots a bundled FastAPI backend on loopback (127.0.0.1:8765) and renders the editor in a WKWebView from that same origin. No browser, no server, no port open to your network.
Contract-review platforms rent you the workflow by the seat and run your unsigned agreements through their servers. SiloDraft is a single purchase, on your Mac, with unlimited local drafting, playbook checks, clause generation, and redline compares — because it all runs on hardware you already own. Buy once, keep the deal room.
