What Kuro actually does
A dark theme shaped around the page
Kuro maps page colours through an adaptive OKLCH engine instead of placing one blunt inversion over everything. It preserves visual hierarchy, protects photography and video, and repairs contrast while keeping the site recognisable.
- Perceptual OKLCH colour mapping
- Media-aware image and video handling
- AA or AAA contrast policies
Every comfort control, close at hand
Tune brightness, contrast, warmth, palette, and rendering mode for the site in front of you. Switch among Adaptive, Filter, Matrix, and Static engines, save site-specific choices, or apply a temporary override to one tab.
- Four rendering engines for difficult pages
- Per-site, per-tab, and workspace profiles
- Keyboard shortcuts for fast switching
Plans that understand the interface
Kuro builds a deterministic theme plan locally from the page's style structure, then remembers it in a bounded cache. If you explicitly opt in, OpenRouter, DeepSeek, or your own endpoint can refine a privacy-filtered style summary without receiving page text.
- Local planning and cache are on by default
- Remote planning is optional and consent-gated
- Provider, model, endpoint, and design vision stay under your control
Keeps up with pages that never sit still
Single-page navigation, CSS-in-JS updates, open shadow roots, and virtualised interfaces are watched as they change. Kuro refreshes the affected styles before the page can settle back into a bright frame.
- SPA and route-change awareness
- Open shadow-root and adopted stylesheet coverage
- Pre-paint replay from an exact-route cache
A theme that follows your evening
Activate Kuro by clock time, system appearance, or sunrise and sunset from coordinates you enter. A gradual circadian warmth curve can soften the screen as daylight fades without changing the content itself.
- Time, system-theme, location, and circadian modes
- Custom activation and deactivation times
- Adjustable peak warmth and ramp duration
The details that make Kuro feel like Kuro
Adaptive engine
Perceptual colour mapping that respects the page's own hierarchy.
Four engines
Adaptive, Filter, Matrix, and Static modes for every kind of site.
Site-aware plans
Local plans and exact-route cache entries remembered on your device.
Dynamic coverage
SPA routes, CSS-in-JS, shadow roots, and virtualised content stay themed.
Evening automation
Schedules, system theme, sunrise, sunset, and circadian warmth.
Explicit boundaries
Optional AI receives style summaries only after you opt in.
Kuro, up close
Not a policy summary. The actual behaviour.
Theme settings, site rules, provider keys, and generated plans stay in browser-managed storage on your device.
Kuro has no Selfhood account, backend analytics, advertising, telemetry, or cross-site tracking.
Optional remote planning is off by default and sends only a privacy-filtered style summary—not page text, form values, screenshots, or the raw DOM—to the provider you choose.
Asked, answered
Its Adaptive engine rewrites colours in perceptual OKLCH space, respects page hierarchy, isolates media, and repairs contrast. Filter, Matrix, and Static engines remain available as predictable fallbacks for difficult sites.
