You already write in Fountain. We built the editor that runs it on every device, and an assistant that doesn't try to take your job.
We're Fountain-native too. Your scripts open exactly as you wrote them — no conversion, no normalization.
Highland is macOS-only. Arqo runs the same editor on iOS, Android, Windows, web. The phone is the editor, not a viewer.
Going to a producer who needs FDX? We'll round-trip with Final Draft 12 — locked scene numbers, A-pages, dual dialogue intact.
A Fountain script's plain-text honesty + an assistant that helps you find your own through-line. It will not autocomplete your dialogue.
File → Save As → keep the .highland or export as Fountain (.fountain).
Scripts → Import → drop the file. Highland's extras (notes, colored sections) are preserved as Fountain note blocks.
Sign in on iOS or Android. Same script. Same Fountain. Same shortcuts.
FDX, Fountain, plain text, production PDF. Free tier exports too.
Imported as Fountain notes for now. The Bin-equivalent UI ships in 2026-Q3.
Partial. We have Focus mode (hides everything but the current scene). The full word-target Sprint surface is on the roadmap.
No urgency. Highland is excellent on macOS. Switch when you want a phone editor or a memory layer that knows your script — Arqo doesn't replace what you have, it adds what Highland deliberately doesn't.
Through Fountain, yes. Highland .highland format isn't a public spec, but the underlying Fountain text is preserved exactly.
Two scripts on Free. Full editor. Full export. Bring your FDX, see how it lands.
