Every time a SaaS company updates its terms of service, the AI training clauses often shift, sometimes subtly, sometimes dramatically. You might notice new language about "model improvement," broader data retention, or looser opt-out rules. But spotting these changes manually is tedious and error-prone. This worksheet gives you a repeatable, step-by-step method to compare how two versions of a ToS differ on AI training, so you can decide whether the new terms protect your data better or worse.
TL;DR- AI training clauses hide in privacy policies and ToS under different headings (look for "model improvement," "analytics," "product development").
- Side-by-side comparison reveals scope shifts: does the new version train on all user data or only anonymized input?
- Red flags include removal of opt-out language, expansion of "permitted purposes," or looser deletion timelines.
- Use this worksheet to document changes in plain language, then escalate to your legal or vendor-management team.
- Terms Doctor's A-F grading and change tracking can help you spot AI clauses faster and flag updates automatically.
Why AI training clauses matter
AI systems learn from data. The question is: whose data, and with what permission? Over the past two years, companies have rapidly added or expanded AI training clauses into their terms of service. Some are transparent ("we use your content to improve our models, and you can opt out"). Others are vague ("we may use your data for research and product development"). When a company updates its ToS, these clauses often change, sometimes expanding rights, sometimes adding limits.
If you rely on a tool for work, a small shift in AI training language can change your risk exposure. For example:- A design tool might shift from "we don't train on your private projects" to "we train on all projects unless you toggle an option per file."
- A productivity app might expand its definition of "analytics" to include full conversation logs sent to external AI vendors.
- A freelance platform might remove a previous promise to delete contractor portfolios after account closure.
How to use this worksheet
This worksheet is designed for solo reviewers, small teams, and anyone managing vendor compliance. You'll need:
- Two versions of the ToS (current and previous, or two different vendors)
- 30–45 minutes of focused time
- A text editor or spreadsheet to record findings
- This worksheet printed or open in a second window
Step 1: Locate and extract AI training language
AI training clauses don't always live in an obvious section. Search for these keywords in both documents:
- "AI," "machine learning," "model"
- "Train," "training," "learn," "learning"
- "Analytics," "product development," "research"
- "Improvement," "service improvement"
- "Data processing," "permitted purposes"
- "Aggregate," "anonymize," "pseudonym"
- "Vendor," "third-party AI," "service provider"
Why this matters: AI clauses are scattered across privacy policies, terms of service, data processing addenda, and cookie notices. If you only skim the Privacy Policy, you'll miss the AI training clause buried in the "Product Development" section of the ToS.
Step 2: Create a side-by-side comparison table
Create a simple three-column table:
| Aspect | Version 1 (Old/Vendor A) | Version 2 (New/Vendor B) |
|---|---|---|
| Data types used for training | Specify exactly what data: user content, logs, metadata, analytics? | |
| Scope of training | Does it apply to all users or certain tiers? Opt-in or opt-out? | |
| Retention timeline | How long is data kept before deletion? | |
| Third-party sharing | Does the company share data with external AI vendors? | |
| Opt-out mechanism | Can users disable training? Per-account or per-asset? | |
| Transparency | Does the company disclose how training works? | |
| Deletion rights | Can users request deletion of their training data? |

This quote captures the pain point: manual comparison is slow and error-prone. A structured table forces precision.
Step 3: Spot changes in scope and language
Now compare each row. Look for these red flags:
Scope expansion:- Old: "We use anonymized analytics to improve search."
- New: "We use all user content, including files and conversations, to train AI models."
- Flag: Data definition broadened from analytics-only to full content.
- Old: "Users can opt out of AI training via Settings > Privacy."
- New: "AI training is enabled by default. Contact support to disable." (or no mention of opt-out)
- Flag: Switching from opt-out to opt-in is a major shift in user control.
- Old: "We train on user feedback to improve our sorting algorithm."
- New: "We may use your data for research, development, and other business purposes."
- Flag: "Other business purposes" is open-ended and harder to enforce.
- Old: "Training data is deleted 30 days after account closure."
- New: "Training data may be retained for up to 2 years for model refinement."
- Flag: Longer retention means your data is at risk longer.
- Old: "We train models internally and do not share user data with AI vendors."
- New: "We may share training data with selected third-party AI vendors for model development."
- Flag: Your data is now leaving the company's control.
Step 4: Document your findings
Write a plain-language summary of what changed. You don't need legal jargon, focus on practical impact:
Example summary:
"Version 2 now trains AI models on all user documents (not just analytics). Previously, only anonymized metadata was used. Version 2 also removes the opt-out button and requires contacting support. Third-party AI vendors can now access our training data. Retention was extended from 30 days to 2 years post-deletion."
Key takeaway: Changes in AI training scope, removal of opt-out levers, and new third-party sharing are the biggest risks to your privacy.

How Terms Doctor can help
Terms Doctor runs 101 consumer-protection checks on every website you visit, including dedicated checks for AI training clauses. When you visit a SaaS tool's pricing page or sign-up form, the extension automatically pulls the ToS and flags AI training language, third-party data sharing, forced arbitration, and auto-renewal risks, all ranked A-F.
If a company updates its ToS, Terms Doctor's change-tracking feature alerts you to what shifted. You can then use this worksheet to dig deeper into the specific language changes and decide your next move.
Not legal advice: These comparisons and checklists are informational tools. If you're signing a contract worth significant money or exposure, have a lawyer review the final terms.
