Alongside client work I build small Chrome extensions that solve problems I kept hitting myself. The Brand Voice Checker lets you highlight any text on any page — LinkedIn, Google Docs, your CMS — right-click, and get an instant brand voice score out of 100 with an A–E band, measured across ten calibrated language dimensions against your own voice profile. It also runs a compliance pre-screen on claims, promises and guarantees against EU, UK, Irish and US advertising rules, with numbered on-page highlighting and one-click copy of the rewritten version. The YouTube CPA Calculator sits directly inside YouTube Studio and answers the question every channel owner eventually asks: what is a subscriber actually costing me? It turns the numbers already on screen into a clear cost per subscriber, so you can see which videos are growing the channel efficiently and which are quietly burning budget — no exports, no spreadsheets.
