System requirements

Ktlyst runs in your web browser — no install. Here's what you need for the best experience.

Supported browsers

Use a recent version of:

  • Google Chrome 104+
  • Microsoft Edge 104+
  • Safari 15.4+ (macOS / iPadOS / iOS)
  • Mozilla Firefox 104+

Older browsers and Internet Explorer aren't supported. Keeping your browser up to date is recommended.

Devices

  • Desktop / laptop (Windows, macOS): full editing.
  • Tablet, e.g. iPad (screen width 768px and up): full editing with a touch-friendly interface.
  • Phone: view-only — sign in, browse your canvases, and pinch-to-zoom a read-only viewer. Editing needs a tablet or PC; phones stay view-only in landscape orientation too.

Feature notes by browser

  • Floating reference window (Pro): an always-on-top window on Chrome / Edge; on Safari and Firefox it opens as a normal pop-up (allow pop-ups).
  • Export to PDF / PNG (Pro): works in all supported browsers.
  • Paste a screenshot (Cmd/Ctrl+V): requires a browser with clipboard support.
  • Video / GIF frame picker: drop an MP4 / WebM / MOV / M4V / OGV video or a GIF and scrub to grab the exact frames — only the frames you pick are saved; the source never leaves your device. Frame-by-frame GIF picking needs a browser with the WebCodecs API (recent Chrome / Edge / Safari) over HTTPS; otherwise the GIF's first frame is added.

Connection & storage

  • Internet connection required. Cloud sync and AI generation run online; Ktlyst doesn't work offline.
  • Free plan: your images are stored in your browser on the device you added them on.
  • Pro plan: 10 GB of cloud storage (expandable) with sync across your devices.
  • JavaScript, cookies and local browser storage must be enabled. Strict private-browsing or tracking-prevention settings can affect saving and sign-in.

Recommended

A reasonably modern laptop, desktop, or iPad-class tablet with the latest version of one of the supported browsers, and a stable internet connection. No special graphics card is required.
