The AI era's dirty little secret

You're still just… waiting.

AI models got 10× smarter. Your workflow? Still tab-switching every 20 seconds.

You give up waiting and open YouTube.

Then 90 minutes disappear.

You find out it finished 30 minutes ago.

Momentum: gone.

You tab-switch 10 times just to check.

Each switch costs ~23 seconds of focus.

You forget what you were even doing.

"Wait, what was I asking for?"

Features

One tab. Six AIs. Zero babysitting.

Everything you need to stop watching and start shipping.

FAQ

Questions?

Which AI assistants do you support?

Claude, ChatGPT, Gemini, Perplexity, Grok, and Higgsfield (image + video generation) — all on day one. Next up: Midjourney web, Sora, Apple Music.

Is my data safe?

Everything runs locally in your browser. Summaries are generated on your machine, never sent to our servers. Spotify OAuth uses PKCE with no client secret on our side. Zero telemetry, zero analytics. Open source under PolyForm Noncommercial.

Why $9.99 for 72 hours, $29 after?

Founding Member pricing — our way of thanking early adopters. After launch week, it's $29 lifetime. Once you buy, you're locked in forever — including future features.

Will you switch to a subscription later?

No. Lifetime buyers are grandfathered in forever. We may add optional subscription tiers for future server features (mobile push relay, team dashboards), but everything you bought today stays lifetime.

Do I need Spotify Premium?

Only if you want playback controls — that's Spotify's API rule, not ours. Every other Nok feature works whether you have Spotify or not.

What if I don't like it?

30-day no-questions-asked refund via Gumroad. Reply to the receipt email, we'll process your refund.

What browsers?

Chrome, Edge, Brave, Arc — any Chromium-based browser (Manifest V3). Firefox and Safari are on the roadmap.

Does Nok work with the desktop apps (ChatGPT / Claude / Gemini)?

Nok captures completions inside your browser tabs. The official desktop apps already have built-in OS notifications — Nok adds the missing layer for web sessions: 3-line summary, quick reply, custom sound, Slack/Discord/Teams relay. If you live in tabs, Nok is for you. Higgsfield is web-only, so Nok is the only way to get notified there.
