Bring your Celtx scripts. We respect every revision mark, every dual-dialogue block, every locked scene number — and we will not paywall your own PDF the day your subscription lapses.
Celtx puts your PDF behind an active subscription. Arqo's free tier exports FDX, Fountain, and production PDF — forever. Lapsing doesn't freeze your work.
Celtx grew into a production suite; the script editor stopped being the priority. Arqo is screenwriting first — Fountain-native, FDX-clean, mobile-real.
Pricing: $9/mo Pro · $24/mo Studio. No "assistant add-on" line item. Plug in your own Anthropic key today; OpenAI + Google routing rolls out across the assistant routes through 2026 — no markup on what you spend.
Where did Mira last appear? What scenes happen on the rooftop? The memory layer surfaces your own through-line — it does not autocomplete your dialogue.
In Celtx Studio: Script → Export → Final Draft (.fdx). On free Celtx, the FDX export sits behind the paywall — see FAQ for the workaround.
Scripts → Import → drop the .fdx. Scenes, dialogue, dual-dialogue, revisions, and locked scene numbers come through.
Open the imported script in Arqo. Spot-check the first 3 scenes — element types, character names, scene numbers. Export FDX back out if your producer asks.
Sign in on iOS or Android. Same script, same editor — Celtx Mobile is a viewer; Arqo on phone is the editor.
Celtx requires a paid tier for FDX export. Workarounds: (1) start a Celtx free trial of a paid plan, export FDX, then cancel. (2) Copy your script into a plain-text Fountain file and import that into Arqo. (3) Sign up for our .celtx native-import waitlist below — when it ships, we'll email you.
Not yet. Native .celtx parsing is on the roadmap and we are taking waitlist names — sign up at the bottom of this page. Today: export FDX from Celtx, import into Arqo.
Arqo focuses on the script. Production breakdowns (scheduling, breakdown sheets, call sheets) are not in Arqo today and won't be — that's a different tool. Your Celtx production data stays in Celtx; the script comes to Arqo.
In Celtx, your editor and exports go behind the paywall when a subscription ends — your scripts are still on their servers, but you can't get them out without paying again. In Arqo, every format — FDX, Fountain, PDF — comes out on the free tier from Account → Export everything. You always get your work out.
Yes. Round-trip the FDX between them. Most writers we've talked to do exactly this once a script gets close to production.
Two scripts on Free. Full editor. Full export. Bring your FDX, see how it lands.
