Verbinal Thought

Think clearly before you build

A native Mac workbench for thinking through the systems you're about to build. You talk a design through with an AI thinking partner, and every idea worth keeping becomes a Thought: saved, tagged, searchable, and ready to reuse. This is a thinking tool, not a coding tool — it sits upstream of the work.

A typical session

Reason out loud about the system you're designing. The AI challenges assumptions, proposes alternatives, and surfaces contradictions. It does not design it for you.
Promote any exchange — a sentence, a decision, a whole strategy — into a Thought you can find again.
Drag prior Thoughts into a new conversation so today's thinking builds on yesterday's.
Arrange Thoughts on a project canvas to see how the pieces fit.
Convert a pile of Thoughts into a spec, an assumption ledger, an assertion list, or a handoff brief, and export it as clean markdown.

AI proposes, you commit

The AI is a thinking partner, not a ghostwriter. Every change it suggests lands as a reviewable proposal you accept or reject. There is no “design-for-me” button. AI uses OpenAI today and requires an API key you supply.

Your thinking stays yours

Local-first: Thoughts live in a local SQLite file on your Mac; your API key is stored in the macOS Keychain. No accounts, no cloud sync we operate, no server-side copy of your work. No telemetry, no tracking, no ads, no third-party analytics.

Fully usable offline

Write, tag, link, search, and export with no AI at all. AI is an option you opt into with your own key, not a requirement.

What this is not

It does not write source code, read your repo, or run your tests. It helps you think clearly about what you're building.

A native Mac app

Built in Swift and SwiftUI — no Electron, no web wrapper. Requires macOS 14 or later.
