How to Protect Your Script When Using AI Analysis Tools
Worried about uploading your screenplay to an AI tool? Here's what to look for in script security — from encryption to upload certificates.

The number one concern we hear from filmmakers considering AI analysis: "Is my script safe?"
It's a valid concern. A leaked script can derail a project, damage relationships, and cost millions in lost value. Here's what you should look for — and what Kalezio does differently.
The Risk with General AI Tools
When you paste your script into ChatGPT, Claude, or any general-purpose AI, you're uploading your intellectual property to a system that may:
- Use your content for training — Most general AI tools include language in their terms that allows using uploaded content to improve their models
- Store your content indefinitely — Your script may live on servers long after you've closed the browser tab
- Lack audit trails — No way to prove when you uploaded content or that it wasn't accessed by others
For casual brainstorming, this might be acceptable. For unreleased scripts worth millions in production value, it's a non-starter.
What to Look For in AI Script Tools
If you're evaluating AI tools for script analysis, here's a security checklist:
1. Data Processing Transparency
Does the tool explain exactly what happens to your script during analysis? Can they describe the technical pipeline, or just promise "it's secure"?
2. No Training Policy
Does the tool explicitly guarantee that your content will never be used to train or fine-tune AI models? This should be unambiguous in their terms.
3. Data Deletion
What happens to your script after analysis is complete? Is the raw content deleted, or does it persist in their systems?
4. Encryption Standards
Is data encrypted both in transit (TLS) and at rest (AES-256)? These are table-stakes for any tool handling sensitive intellectual property.
5. Proof of Submission
Can you prove when you uploaded your script? If a similar concept appears later, do you have any verifiable record of prior creation?
How Kalezio Handles Script Security
We built Kalezio for an industry where a leaked script is a catastrophe. Our approach:
Anti-contamination pipeline — Your script is obfuscated before any AI processing. The Oracle never sees your raw content in its original form.
No raw script storage — Once analysis is complete, the original content is deleted from processing systems. Only your analysis results are retained.
No training on your content — Your scripts are never used to train, fine-tune, or improve our AI models. This is a hard technical guarantee, not just a policy.
Upload certificates — Every script upload generates a timestamped, cryptographic certificate. It includes a SHA-256 hash of your content, the exact upload time, and your identity — without revealing any actual content. You can share this publicly as proof of prior creation.
Encryption everywhere — TLS 1.3 in transit, AES-256 at rest. Your content is encrypted at every stage.
The Bottom Line
AI analysis tools can provide enormous value to filmmakers and studios. But not at the cost of your intellectual property. Before uploading any unreleased script, verify that the tool meets the security standards your content deserves.
