zQinta

Start with any topic — "Neural Networks", "The French Revolution", "Music Theory" — and zQinta generates a visual tree of connected concepts. Each node is a sub-topic you can expand further, building a complete map of the subject. It mirrors how understanding actually works: new ideas connect to what you already know.

Every expansion offers three levels: Beginner (3–5 clear sub-concepts), Intermediate (5–8 with more depth), and Advanced (8–20, expert-level). Start at the surface and dive as deep as you want — from a 5-minute overview to a 200-level deep-dive on the same topic.

Yes. Every concept card has its own chat — ask follow-up questions, request examples, or get a different explanation. The chat stays scoped to that concept, so your Q&A never gets lost in an endless feed like a regular AI chat.

Yes. From any concept, generate a finished video with synchronized narration and sound built in — powered by Seedance 2.0, using your own API key (BYOK). The video renders under the concept and can be published to the Market as part of a course.

Yes. With AI you can generate every aspect of a course from your knowledge tree: a finished video (with audio baked in via Seedance 2.0) and the full written text (concept explanations, overviews, notes). You choose how to package and sell it — as a video course, a text-only guide, or both together. Set your own price on the Market and buyers pay you directly via Stripe. One knowledge tree, every format, your revenue.

Yes. Pick from five response styles — Short informative, Long and detailed, Include many examples, Explain like I'm 5, and Deep and professional. Structured formatting (headings, bullets) and step-by-step for how-to topics are always on.

Yes. Choose from 27 languages — English, Spanish, French, German, Russian, Armenian, Japanese, Korean, Chinese, and more — or pick "Auto" to match the language of your prompt. The AI writes its entire answer in your chosen language regardless of how your question is written.

Absolutely. Every concept has a private notes field — write your own summary, examples, or questions. Your notes are never sent to the AI; they stay yours.

Free tier searches concept titles. Premium unlocks full-content search — find any word inside any concept's explanation across all your maps, instantly.

Yes — Premium can export any map as a polished PDF (clickable graph + detail pages), JSON (full workspace backup), or Markdown (clean heading hierarchy for notes or blogs). You can also import JSON to merge workspaces.

Premium includes CloudKit sync — your knowledge maps stay up to date across every Mac signed into the same iCloud account, end-to-end encrypted.

No — the app ships with free Apple AI (on-device + Cloud Compute). For stronger reasoning (GPT-4o, Claude), bring your own OpenAI or Anthropic API key. Your key is stored in your Mac's Keychain; we never see it.

Completely. Your boards live locally on your Mac. CloudKit sync is end-to-end encrypted. We collect no personal data, run no analytics on your content, and never sell anything. If you bring your own AI key, your prompts go directly to that provider — not through us.

Yes. Generate a knowledge tree, then use AI to create a finished video (with synchronized audio via Seedance 2.0) and polished written content from it. Package any combination — video, text — and publish it to the Market as a course. Set your own price ($0–$50), and other users pay you directly via Stripe (we take a 30% platform fee). Stripe Connect handles payouts to your bank.

Browse the Market, watch the intro video, read the AI-generated overview, and pay securely with Stripe. The course imports into your workspace as a knowledge tree you can explore, expand, and learn from — in whatever format the creator published (video, text, or both).

Yes — zQinta auto-updates via Sparkle, so you always have the latest version without lifting a finger. No App Store required.

Any Mac running macOS 15 (Sequoia) or later, Apple Silicon or Intel. The app is a native macOS build — no Electron, no browser, just fast native performance.

Yes — cancel whenever, no questions asked. There's a dedicated “Unsubscribe” button right in the app's Subscription tab. Canceling ends your Premium at the next billing date and you drop to the Free plan. Your maps, concepts, notes, and purchased courses all stay — nothing is deleted. You can keep buying courses on the Market as a free user and re-subscribe whenever you like.

You can delete your account at any time from the app's Subscription tab or the user menu. Deleting your account cancels your subscription (no future charges), wipes your account from our servers — profile, maps, posts, comments, notifications — and signs you out everywhere. We keep only an anonymous financial record for accounting purposes, as required by law. This is permanent and cannot be undone, so we ask you to confirm.

Nothing is lost. If you cancel or your subscription lapses, you keep all your maps, concepts, notes, and any courses you bought. You simply drop to the Free plan's limits (fewer maps, shallower depth, fewer AI messages). CloudKit sync pauses and AI generation uses the free Apple AI limits. Re-subscribe any time to restore everything instantly.
