InteScene as a Celtx alternative
InteScene is an all-in-one Celtx alternative that spans screenwriting, breakdowns, scheduling, budgeting and call sheets in a single connected workspace. You write in an industry-standard editor with live pagination and colour-coded revisions, the AI breaks the script down into one shared catalogue, and that catalogue drives the schedule, budget and call sheets automatically. It imports and exports Fountain and FDX, plans start free, and paid tiers begin at GBP 12 per month with a two-week free trial.
Celtx is a well-known pre-production tool, so an alternative should cover scripting and planning without forcing data between disconnected tools. InteScene starts in an industry-standard screenplay editor that formats scene headings, action, dialogue and the rest as you type, counts pages live and supports the full production-office revision workflow with colour-coded rounds, locked revisions and accept or reject. Two writers can co-write the same scene at once thanks to a true merge engine. From there the AI reads your scenes and pulls every element into a single shared catalogue. That catalogue is the spine of the rest of the workspace. It drives a three-view scheduler with an AI shooting-order generator and a live conflict engine, a two-speed budget that reaches a full chart of accounts, casting, locations and auto-generated call sheets and sides. AI runs throughout: scene summaries, shot lists, storyboard frames, a six-lens script analyser covering legal clearance, cost, dialogue voice, structure, sensitivity and proofing, and a continuity tracker built for out-of-order shooting, all metered by one transparent credit wallet with you keeping the final say. Scripts import and export as Fountain, FDX with revisions, PDF and project JSON, so you are never locked in. Plans start free, paid tiers run from GBP 12 per month with a two-week free trial.

Frequently asked questions
Is InteScene a good Celtx alternative?
InteScene is a good Celtx alternative for teams that want screenwriting, breakdowns, scheduling, budgeting and call sheets in one connected workspace. You write in an industry-standard editor with live pagination and colour-coded revisions, the AI breaks the script down into one shared catalogue, and that catalogue drives the schedule, budget and call sheets automatically. It also adds AI across the pipeline and real-time co-writing in the same scene.
Can InteScene import my existing scripts?
Yes. InteScene imports screenplays from Fountain, Final Draft FDX with revision colours intact, plain PDF and a full InteScene project JSON. There is also a neutral 'Migrate from another tool' path that reads another screenwriting app's project archive and rebuilds the screenplay as fully editable blocks. You can export back out as Fountain, FDX, PDF and JSON, so nothing is trapped.
Does InteScene include AI features?
Yes. The same AI that reads your script breaks it down into a production database, summarises scenes, suggests shot lists, generates storyboard frames, proposes an optimised schedule, runs a six-lens script analysis and tracks continuity. Every AI action shows its credit cost before you run it, you are never charged for a cancelled or failed job, and AI features are optional and human-in-the-loop, with you always having the final say.
