Comparison
A lot of marketing teams use ChatGPT to check EU ad copy. It gets some things right. But GDPR compliance requires article-level precision that a general assistant is not trained to give. Here's an honest comparison.
Trained specifically on GDPR articles 6, 7, 9, 13, and 14 as they apply to marketing copy. Maps every flag to the specific obligation, detects bundled consent, special category data inference, and third-party disclosure gaps. Returns a transparency score and a before/after compliant rewrite.
Excellent general-purpose assistant for drafting and editing marketing copy. Can discuss GDPR concepts and suggest improvements when prompted carefully. Not trained on current enforcement decisions, DPA guidance, or platform-specific EU policy, and has no structured detection framework for article-level compliance.
Side by side
ChatGPT can help with GDPR awareness. Legalify is built for GDPR audit. The difference is precision and accountability.

|---|---|---|
Article-level GDPR detection Findings mapped to Art. 6, 7, 9, 13, 14 — not generic 'may be risky' language. | Yes | No |
Art. 9 special category (health) inference Detects when product context lets sensitive health data be inferred. | Yes | No |
Bundled consent detection (Art. 7(4)) Flags consent tied to a purchase or other action that is not freely given. | Yes | No |
Consistent, structured output Same compliance framework applied every time — not prompt-dependent. | Yes | No |
Before/after compliant rewrite Each flag ships with a ready-to-use rewrite of the problematic sentence. | Yes | Partial |
Current DPA guidance and enforcement awareness Detection tuned to actual enforcement decisions, not just regulation text. | Yes | No |
Third-party recipient disclosure gaps (Art. 13/14) Catches copy implying Meta/Google targeting without disclosed recipients. | Yes | No |
Transparency score Single quantified score for the copy's overall disclosure quality. | Yes | No |

FAQ
ChatGPT can identify obvious issues if prompted carefully, but it lacks a structured GDPR detection framework. It does not map findings to specific articles, does not apply current DPA enforcement guidance, and produces different results depending on how you phrase the question. For a one-off sense-check it can help; for consistent pre-launch compliance auditing it is not reliable.
Legalify applies a structured framework to every scan: Article 9 special category data inference (health products implying sensitive data without explicit consent), Article 7(4) bundled consent (consent tied to a click or purchase), and Article 13/14 third-party disclosure gaps (personalised ad targeting without named recipients). ChatGPT does not have a deterministic detection layer for these — findings depend on prompt wording and vary between sessions.
For teams who ship EU ad copy regularly, yes. A dedicated tool gives consistent, accountable output that you can use as evidence of a pre-launch compliance process. ChatGPT's output is not auditable in that way — it changes between sessions and cannot be cited as a compliance check.
Many teams do. ChatGPT is useful for early drafting and general copywriting; Legalify is used at the pre-launch audit stage to check the final version against specific GDPR articles before it goes live.
