Wayscript vs Celtx

The longer answer

Formatting and interchange: watch the directions

Both apps format to industry standard and print a clean, submission-ready PDF. The difference is in the doors. Celtx's interchange is one-way on both counts — it exports Fountain but doesn't natively import it, and it imports Final Draft (.fdx) but doesn't natively export it. Wayscript reads and writes both formats natively, in both directions. In practice that means work moves into Celtx more easily than it moves out, while Wayscript is deliberately easy to leave — which is exactly the property that makes it safe to commit to.

Planning: index cards vs the story behind the script

Both apps do index cards, and Celtx's are a solid, familiar take. Wayscript's planning runs deeper into the story itself — beat-sheet templates and index cards sit alongside a corkboard, outliner, narrative threads and a timeline, each a different window on the same structure, over the script and the prose alike. If planning for you means arranging scenes before a shoot, Celtx covers it; if it means holding a season, a series or a world in your head, Wayscript gives that shape more places to live — including a branching quest graph with Play Mode and ink, Yarn and JSON export on the Author plan, for stories that are played rather than filmed.

The story bible: filing vs knowing

Celtx has genuine story development tools — character catalogues, notes and development documents that feed its pipeline. What they don't do is connect themselves. Wayscript's vault treats the bible as a working model — typed entities joined by real relationships, backlinks written automatically from every mention in the script, and a live graph of how cast and world fit together. Name a character in scene forty and her entry already lists it. For a production binder, Celtx's catalogues are fine; for the story's own memory, self-linking is the difference between filing and knowing.

Collaboration: browser teams vs a shared studio

Both apps do real-time collaboration well. Celtx is team-shaped by design — the browser-first model plus team and education accounts make it easy to put a whole class or crew in one workspace, and its education plans court exactly that audience. On Wayscript, real-time co-editing with presence and comments arrives with the Author plan — one script live on two screens at once. For writing partners, either works; for a production office or a classroom, Celtx's account model is the more natural fit.

Production and pre-production: Celtx's home turf

No hedging on this one — if the goal is getting a script shot, Celtx does things Wayscript doesn't attempt. Breakdowns, shooting schedules, budgets and storyboards live in the same suite as the script, and its revision tools serve that pipeline today. Wayscript ships revision passes and marks now, with locked pages on the roadmap, and has no breakdown, scheduling or budgeting features at all. Writers who stop at the polished draft won't miss any of that; teams taking work to camera should weight this section heavily, and honestly, towards Celtx.

Platforms and offline: the cloud question

This is the mirror image of the last section. Celtx runs in the browser with an Android app, but there's no desktop app, and its offline mode was retired in 2023 — no connection, no writing. Wayscript is local-first with real desktop apps on Windows, macOS and Linux, the full editor on iOS and Android, and a web app when you want one; your files live on your own machine, and cloud sync is encrypted and included on every plan, running automatically — an account is required, so the sync is a given, but the writing itself never waits on a connection. If you write on trains, planes or a farm with patchy broadband, this section settles it by itself.

AI and proof of authorship

On AI, Wayscript's answer is structural. Nothing runs unless you switch it on, and only on paid plans; the Reviewer's brief ends at critique — pacing, consistency, structure — with drafting simply not on the table; Ask AI is a research assistant confined to your own bible; and your words never train anyone's models. Authorship certification sits on top — a tamper-evident record graded from Bronze up to Onyx, attesting that no machine wrote a word. Celtx's current feature list is the place to check where it draws its own line; certification of authorship, either way, is something only one of these tools offers.

Price: what the money buys

Both start free. Celtx's free plan holds one project; Wayscript's free plan holds three at once, and only projects you started yourself count toward that cap — samples and imported manuscripts ride along free. The editor, planning, the story bible, every export format and cloud sync are all in the free tier. Paid, Celtx's Writer plan runs about $12.49/month, and the team and studio tiers above it carry the pre-production features — check Celtx's current pricing for those. Wayscript's Author plan is $8/month ($72/year) for unlimited projects, co-writing, analysis and the interactive studio, with Author + Reviewer at $14/month for the reviewer in full. If you need the production pipeline, Celtx's price buys something Wayscript doesn't sell; if what you need is the writing studio, Wayscript is the cheaper seat.

Switching from Celtx

The clean path is Fountain — export your script from Celtx as Fountain and import it into Wayscript, which reads it natively, so scenes, sluglines and dialogue survive the trip as structure rather than flat text. Celtx doesn't natively export Final Draft (.fdx), so that route isn't available, and it's fair to say the move takes one more step than leaving an FDX-native tool. Catalogue and development notes are re-created in the vault by hand; budget an afternoon for most projects, and expect the hours to feel well spent once the bible starts linking itself. Your Celtx project stays in your account as an archive, so the door back stays open.
