nonolingo
Fix your English where you type, on Mac
What is nonolingo?
nonolingo is a macOS app for people who write English at work as a second language. In any text box (Slack, Gmail, Teams, Telegram, WhatsApp, Notion, a browser field) it shows two lines under your draft: a clean fix that keeps your words, and a native rewrite that sounds like a fluent speaker. Press Tab to accept, Esc to ignore; it never sends for you. You can also type in your own language and get natural English back, select a message to get reply ideas, or translate it with its tone. 7 days free with everything on, no sign-up or card, then free every day. Pro is a one-time pass ($1.99 for 30 days or $19.99 for a year) that never renews. Requires macOS 14+, Apple silicon or Intel.

When you have one app you have to grind on every single piece of it. But when you have a portfolio, we're looking at incremental things we can roll across multiple apps to lift the entire business.
Portfolio thinking shifts you from grinding one app to lifting all apps simultaneously
Price testing each individual app yields marginal gains. But a paywall colour test proven across one app, then rolled to 36 others, multiplies the return. Michael deliberately avoids deep per-app optimisation in favour of insights that are portfolio-portable. The strategy is ruthless prioritisation: only do the work that compounds across the whole.
I made a video about that and it got like 1 something million views and that strategy that I brought to the internet has since been repeated so many times that it's referred to as the compare lists method.
Validate Demand by Making a Video About the Problem Before Building Anything
Ben discovered the demand for a safer Instagram unfollower tool by creating a video explaining a manual workaround — not by building anything. The video drove over a million views and sent traffic to a competitor's tool, proving massive latent demand before he spent a dollar on development. He then spent 4 years watching the idea mature before building it himself.
There's a play for whatever you're stuck on.
