The short answer: FinalBit — the platform formerly known as NolanAI — is the best AI tool for screenwriters in 2026 if you plan to shoot what you write, because it carries a script through breakdowns, budgets, and schedules. Sudowrite is the better pure writing partner for developing story and dialogue. Arc Studio is the cleanest traditional screenwriting app for outliners, and Final Draft 13 remains the file format everyone downstream will ask you for. Below: six tools compared on verified pricing, free-tier reality, and what each one is actually best at.

What the pricing pages don’t make obvious
Three gotchas, all verified on the vendors’ own pages. First, FinalBit’s free Basic plan watermarks your PDF and Final Draft exports — fine for drafting, unusable for sending to a producer. Second, Arc Studio’s headline subscription does not include its AI features: its pricing page lists the Table Read and Research Assistant as optional add-ons you buy credits for separately, on top of Essentials or Pro. Third, Sudowrite’s credits only roll over on its top Max plan — on Hobby and Professional, unused credits expire every month, so a quiet writing month is money spent on nothing. Also worth knowing before you search for it: NolanAI no longer exists under that name. It rebranded to FinalBit, and the old address redirects there.
1. FinalBit (formerly NolanAI) — best all-in-one, script to production
FinalBit is a browser-based screenwriting platform with an AI Co-Pilot for dialogue and scene work, plus script coverage, automated breakdowns, AI budgets you can export to PDF and Excel, storyboards, and scheduling. Basic is free with one project and 100 one-time AI requests. Creator runs $40/month ($28 on annual billing) with unlimited scripts and AI requests plus 100 monthly AI video credits. Pro runs $100/month ($70 annual), raising video credits to 210 and unlocking the full automated pre-production suite and advanced analytics. Students get 50% off annual plans.
Pros: Only tool here that follows the script into production; generous unlimited AI on Creator; free tier to start.
Cons: Free exports are watermarked; the NolanAI-to-FinalBit rename means older tutorials point at a brand that no longer exists.
2. Sudowrite — best AI writing partner for story and dialogue
Sudowrite was built for fiction writers, and screenwriters borrowing it for development work get its Story Bible for keeping characters and world details consistent, its Muse model tuned for prose and dialogue, and feedback tools that read a scene back like a tough script reader. Plans differ only in credits, not features: Hobby & Student is $10/month billed annually (225,000 credits), Professional is $22 (1,000,000 credits), and Max is $44 (2,000,000 credits, the only tier where unused credits roll over, for up to 12 months). We cover it in depth in our Sudowrite review. You will still finish and format the script in a dedicated screenwriting app — Sudowrite is the development partner, not the delivery tool.
Pros: Strongest story-consistency tools here; every plan unlocks every feature; free trial with no credit card.
Cons: Credits expire monthly except on Max; not a production-formatting tool.
3. Arc Studio — best traditional screenwriting app
Arc Studio is the modern, clean take on screenwriting software: proper automatic formatting, a strong outlining and beat-board workflow, and real-time collaboration that feels like Google Docs. Its free tier covers two scripts in the web app. Essentials is $69/year with the desktop and mobile apps and unlimited scripts; Pro is $99/year and drops to $79/year on renewal, per its pricing page. Just budget honestly for the AI extras — table reads and the research assistant are credit-based add-ons, not part of the subscription.
Pros: Best outlining workflow here; cheap annual pricing with a renewal discount; free tier is genuinely usable for drafting.
Cons: Free exports carry a watermark; AI features cost extra credits on top of the plan.
4. Squibler — best for fast, high-volume first drafts
Squibler generates full-length screenplays and books from a brief, with formatted scenes and dialogue, and keeps characters and plot elements organized as it goes. Its free plan includes 1,000 AI credits a month with no time limit — a real drafting allowance, not a weekend trial. Plus is $29.99/month or $15.83/month billed annually for 10,000 credits a month and PDF/DOCX export; Pro is $89.99/month or $49.17/month billed annually and is the only tier with unlimited credits. Treat the output as raw material: generated scenes still need a writer’s rewrite pass.
Pros: Permanent free plan with monthly credits; unlimited generation on Pro; handles books and scripts in one workspace.
Cons: Every regeneration spends credits whether you keep the words or not; monthly sticker prices are steep next to annual.
5. WriterDuet — best for co-writing and writers’ rooms
WriterDuet is the collaboration specialist: multiple writers in one script in real time, with revision tracking and clean Final Draft export. Its free tier covers three projects, and paid plans start at $9.99/month (Plus), with Pro at $11.99 and Premium at $13.99. Its AI assists are lighter than FinalBit’s or Sudowrite’s — think rewrite and dialogue help inside the editor rather than generation — which for many writing teams is exactly the right dose.
Pros: Best real-time co-writing here; free for three projects; exports clean .fdx files.
Cons: AI features are assistive, not generative; solo writers may prefer Arc Studio’s outlining.
6. Final Draft 13 — the delivery standard, deliberately not an AI tool
Final Draft is on this list because the industry runs on its .fdx format: when a producer asks for “the file,” this is the file. Version 13 lists at $249.99 and was $199.99 on its own product page when we checked; a subscription Suite option also exists. Be clear-eyed about what you’re buying — Final Draft’s product page makes no AI claims, and that is by design. Write and develop in the tools above if you want AI help, then deliver in Final Draft format (every tool on this list exports .fdx), or keep Final Draft itself for production drafts and revisions. For more on the prose side of the craft, see our roundup of the best AI tools for authors, and if your script is headed for a channel, our best AI tools for YouTubers picks up where the script leaves off.
Pros: Industry-standard format and revision workflow; one-time purchase option.
Cons: No free plan; minimal AI by design; major-version upgrades cost extra.
Frequently asked questions
Can AI write a screenplay for me?
It can generate scenes, dialogue, and full draft structure — Squibler and FinalBit both do it — but a generated draft is a starting point, not a shooting script. Expect to rewrite heavily. There’s also a legal reason to stay hands-on: the US Copyright Office requires human authorship for protection, and FinalBit’s own writing on this is blunt about it.
What is the best free AI screenwriting tool?
Squibler’s free plan, for its 1,000 AI credits a month with no time limit. FinalBit Basic and Arc Studio’s free tier are good for formatting and drafting, but both watermark exports, so budget for a paid month when it’s time to send the script out.
Do I still need Final Draft?
Only if a producer, contest, or writers’ room requires working in it directly. Every tool here exports .fdx, so you can deliver a Final Draft file without owning Final Draft. If scripts are your income, the $199.99–$249.99 one-time price eventually pays for itself in friction avoided.
Which tool is best for a first-time screenwriter?
Arc Studio. The free tier teaches you real screenplay format and outlining without watermarks on your drafts in progress, and Pro at $99/year is the cheapest full-featured step up here.
Our pick: FinalBit Creator if this script is getting made; Sudowrite Professional if you’re still finding the story; Arc Studio Pro if you want one clean app and think in outlines. Start free, and upgrade the month you need clean exports — not before.
