Your private AI workspace.
A local AI assistant that researches, writes, and creates with you — running entirely on your Mac. Zero tokens. Unlimited use. Nothing leaves your machine.
It does the research. You make the decisions.
COTID™ browses the web, reads sources, pulls data, and synthesizes what it finds — then helps you turn that research into finished documents, charts, and roadmaps. All privately. All on your device.
Tell it what you're working on. That's it.
Create a project. Tell the AI your topic, your field, and any context it should know. From then on, every document, every search, every answer is shaped by your project — no repeating yourself.
Write with AI. Not after it.
This isn't "generate a document and hope for the best." You work alongside the AI — it drafts, you refine. It suggests, you decide. Highlight text and ask it to expand, rewrite, cite, or shorten. The AI is your collaborator, not a black box.
Documents. Tables. Diagrams. Notes. Tasks. All in one place.
Everything you need to go from idea to finished work — without switching apps, paying per query, or uploading your data to someone else's servers. Tables, charts, and diagrams are elements — standalone editors you can embed in any document by reference.
Private web research
COTID searches the web, reads sources on your behalf, and folds what it finds into your project's context — nothing leaves your Mac.
Documents
Research papers, memos, specs, plans, slides, flyers, and posters. A full editor with AI built in — and elements embedded right inside. Export as PDF or Word.
Tables
A spreadsheet-grade table editor. Import CSV, write formulas, and drive charts. Embed a table by reference into any document — update once, every instance stays in sync.
Diagrams
Flowcharts and data charts as standalone editors. Describe what you need — or point at a table — and the AI builds it.
Notes
Voice or text. Capture ideas anywhere — the AI organizes them and connects them to your projects.
Tasks
Set your key dates up front — milestones, submissions, deadlines. Add tasks with deadlines and priorities, and the bell in the header flags what's due or overdue across every project.
No tokens. No cloud. No limits.
Most AI tools charge per query, send your data to remote servers, and cap your usage. COTID™ runs on your Mac — there's nothing to meter, nothing to upload, and no one between you and your AI.
Zero tokens
Use it as much as you want. No daily caps, no per-query billing, no "you've hit your limit."
100% private
Everything runs on your device. Your documents, your research, your conversations — never leave your Mac.
