Brushline is an independent studio designing and building a line of AI-native products — software grounded in real intelligence, privacy by default, and a high bar for craft. OneSquad is live today, with more in active development.
Each Brushline product solves a problem the incumbents structurally ignore — and each is built to ship, not to demo.
A controllable workflow from intent to production. Markdown specs are the source of truth; a squad of AI personas — PM, engineer, QA, security, DevOps — build strictly against them, with a human as the gate at every step.
Visit onesquad.aiSee what users experience across web pages and AI conversations — errors, performance, frustration — without reading a word of what they said. Privacy-first by default, live in under 60 seconds, under 14 KB.
Visit hivue.aiLong-form writing with the people, places, and moments of your story tracked automatically in a living knowledge graph. Launching as an AI memoir companion — capture a life story before it's lost, in any language it was lived in.
Coming soonAn owner-owned health record that turns a light daily habit into a factual, shareable record — and notices what changed between vet visits. Private by design, never a diagnostic tool, never tied to a clinic.
Coming soonNot a setting buried three menus deep. Our products collect the minimum, keep your data yours, and make deletion a button — not a support ticket.
AI should surface what you'd have missed and state it plainly — never overreach, never pretend to be something it isn't. We hold a hard line on what our products claim.
We build products people use every day, not impressive prototypes. OneSquad is live, HiVue is in customers' hands, and the bar only goes up from here.
For media, partnership inquiries, support, or any question about a product in the line, we'd be glad to hear from you.
