Quill AI Suggestions

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. As a screenwriter myself, I needed something that understood the craft—and respected the writer."
— James, Creator of Inkwell

You Don't Need Another Robot.
You Need a Partner.
Final Draft costs $250. Every few years, they want you to upgrade again.
→ Inkwell is free to start, with a simple $15/month Pro option if you need more AI. No forced upgrades, no $250 barrier to entry. 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. Your IP feels exposed.
→ Inkwell works offline, saves locally. Your script lives on your machine. We don't store your writing. We don't train models on it. You're safe.
You juggle five apps: one for writing, one for outlining, ChatGPT for brainstorming...
→ Inkwell brings it all together. Write, format, brainstorm with AI, and export—all in one app. No more copy-pasting between windows.
Inkwell is screenwriting software built by writers, for writers—with AI that actually understands its place.
Everything You Need. Nothing You Don't.
Professional screenwriting meets intelligent assistance. Here's what makes Inkwell different.
Conversational Co-Writing
Chat with Quill AI like you'd brainstorm with a writing partner. Ask for scene ideas, dialogue options, character development, or plot twists. Quill understands your script's context and offers suggestions tailored to your story.
Approve or Reject Every Change
Quill never auto-applies edits. Suggestions appear as diffs—added text in green, deletions in red. Click accept or reject. Simple. Transparent. You stay in complete control of every single word.
Import & Export with Fidelity
Seamlessly work with Final Draft (.fdx), Fountain (.fountain), and PDF files. Import your existing scripts without losing formatting. Export to industry-standard formats when it's time to share with producers, agents, or contests.
Offline-Friendly Native App
Write on a plane. Write in a cabin. Write anywhere without worrying about Wi-Fi. 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 to match your needs—faster models for quick suggestions, advanced models for deeper analysis. Switch between models anytime based on what your scene needs. You guide the AI, not the other way around.
Choose Your Writing Environment
Clean, distraction-free interface. Select from Light, Sepia, Focus, or Midnight themes to match your mood and environment. No learning curve—if you've written a script before, you'll feel at home immediately.
You Own Your Words. Always.
We built Inkwell with one core principle: the writer comes first. That means 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.

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.
