Your Screenplay. Your Voice. Your AI Assistant.
Professional screenwriting software with an integrated AI assistant that helps you write faster—without ever taking over.
Private. Offline-capable. Free to start.
Mac & Windows • No credit card required • Works offline
Built for How Screenwriters Actually Work.
With a Partner That Listens.
Professional screenwriting software shouldn't cost $250.
→ Inkwell is free to start, with a $10/month Pro option when you want more AI. No forced upgrades, no paywall. Plus, we import your .fdx files perfectly.
AI tools try to write FOR you, not WITH you.
→ Quill suggests, never replaces. Every change appears as a diff you approve or reject. Your voice stays yours. Your words stay yours.
Cloud-only tools lock you out offline and expose your IP.
→ Inkwell works offline and saves locally. Your script lives on your machine. We don't store your writing or train models on it.
You juggle five apps: one for writing, one for outlining, another for brainstorming...
→ Inkwell brings it all together. Write, format, brainstorm with AI, and export—all in one app. No more copy-pasting between windows.
Everything You Need. Nothing You Don't.
Professional screenwriting meets intelligent assistance. Here's what makes Inkwell different.
Brainstorm with Quill AI
Chat with Quill like you'd brainstorm with a writing partner. Ask for scene ideas, dialogue options, character development, or plot twists—tailored to your story's context.
Approve or Reject Every Change
Quill never auto-applies edits. Suggestions appear as diffs—added text in green, deletions in red. Accept or reject with a click. You stay in complete control of every word.
Import & Export Industry Formats
Work seamlessly with Final Draft (.fdx), Fountain (.fountain), and PDF. Import existing scripts without losing formatting. Export to industry-standard formats for producers, agents, or contests.
Offline-Friendly Native App
Write on a plane, in a cabin, anywhere. Inkwell is a desktop app that saves locally and autosaves your work. When you're back online, Quill is ready—but the editor never stops working.
Model Choice & Control
Choose from multiple AI models—faster models for quick suggestions, advanced models for deeper analysis. Switch anytime based on what your scene needs.
Choose Your Writing Environment
Clean, distraction-free interface with Light, Sepia, Focus, and Midnight themes. No learning curve—if you've written a script before, you'll feel at home.
Mac & Windows — No credit card required
See It in Action
Smart auto-formatting and Quill AI suggestions help you write faster—without ever taking control away from you.
Smart Auto-Formatting
Industry-standard screenplay format applied automatically as you type. No manual formatting needed.
Quill AI Suggestions
Get helpful suggestions for dialogue, action lines, and scene descriptions—you approve or reject every one.
You Own Your Words. Always.
Your privacy, your ownership, and your creative control are non-negotiable.
Your script stays private and local. We never use your writing to train AI. You retain 100% ownership and authorship. Inkwell was designed in line with WGA guidelines – your rights and creative control come first.
Start Free. Upgrade When You're Ready.
Professional screenwriting shouldn't break the bank. Inkwell gives you everything you need to write—for free. Upgrade only when you want more AI firepower.

Built by a Screenwriter, for Screenwriters
"I built Inkwell because I was tired of choosing between expensive legacy software and AI tools that wanted to write for me. I needed something that understood the craft—and respected the writer."
— James, Creator of Inkwell
Inkwell is in active development. Your feedback directly shapes what we build next.
Frequently Asked Questions
Everything you need to know about Inkwell and Quill AI.
Does Quill write for me?
No. Quill suggests—it doesn't author. It can brainstorm ideas, offer dialogue alternatives, or help punch up a line, but every suggestion requires your explicit approval. You're always the writer. Quill is the assistant.
What about copyright and IP?
You own everything you write in Inkwell, period. We don't claim any rights to your material. Using Quill doesn't transfer ownership or create shared authorship—it's legally equivalent to using spell-check or a thesaurus.
Will my writing train the model?
No. We don't store your scripts or use them to train AI models. When you use Quill, only the necessary text snippet is sent to the AI API for processing, and we use data opt-out protections. Your creative work stays yours.
Do I need internet access?
Not for writing! Inkwell works completely offline. You only need internet when you want to use Quill AI. All your script editing, formatting, import/export, and file management works without Wi-Fi.
Can I export to Final Draft?
Yes. Inkwell fully supports Final Draft's .fdx format for both import and export. Your formatting, scene numbers, notes, and dual dialogue are preserved. You can seamlessly collaborate with people using Final Draft.
How does Quill protect my voice?
Quill analyzes your script's existing style and context to make suggestions that fit your tone. Plus, every suggestion appears as a diff—you see exactly what would change before accepting. If something feels off, just reject it. Your voice remains intact.
Is this like ChatGPT writing my script?
No. Quill is designed specifically for screenwriting assistance, not autonomous generation. It works within your script's context, offers options, and requires approval. Think of it as a writing partner who listens and suggests, not a robot churning out pages.
Can I use Inkwell for free forever?
Yes! The free plan includes the full screenplay editor, import/export, unlimited scripts, and a monthly allotment of AI suggestions. You can write complete screenplays without ever paying. Upgrade to Pro for more AI usage, or purchase credit packs for pay-as-you-go flexibility—no subscription required.
