Your intelligent
document engine.
Research, write, and create with an AI collaborator that understands your work — all running privately on your Mac.
Your AI does the research. You write the paper.
Ask COTID™ to find sources on a topic and it searches, reads, summarizes, and cites — bringing everything straight into your document workspace. No copy-pasting between tabs.
Every query, every page it reads, every fact it pulls stays on your machine — never logged, never shared. The research lives in your project and nowhere else.
Write with the AI. Not after it.
A full document editor with AI built into every interaction. Highlight text and ask COTID to expand, rewrite, summarize, or cite. It drafts sections, you refine them. It suggests structure, you make the calls.
Research papers, investment memos, technical specs, business plans, meeting notes — real documents ready to export as PDF or Word.
Charts and diagrams from a sentence.
Describe what you need — "quarterly revenue bar chart" or "user flow diagram" — and the AI lays it out. Arrange it on a canvas, adjust the data, export charts as PNG.
Bar charts, line graphs, pie charts, scatter plots, flowcharts, and data tables — generated from your data or from a description. Charts can also pull their values straight from one of your tables.
Capture everything. The AI connects the dots.
Voice notes, file uploads, pasted links, random ideas. Drop them in and DiffusionScope™ connects them — linking notes to documents, surfacing relevant research, suggesting where things belong.
Everything stays on your machine.
Every document you create, every chart you generate, every source the AI finds — it all lives on your device. No cloud sync. No server uploads. Your work is yours alone.
