Editor's analysis: is Merlin AI Assistant safe?

Merlin (by getmerlin.in / 100x Engineers) is a smaller AI assistant with limited publicly verifiable security documentation. As of the 2026-07-31 scan, here is what the public record shows.

Security certifications: Merlin's privacy policy claims full compliance with SOC 2, GDPR, and ISO standards for users on paid plans (USD 5/month or more). However, these claims could not be independently verified through published certificates or audit reports as of the scan date. No ISO 27001 certificate or SOC 2 report was found on Merlin's website or through public registries.

Data handling: The privacy policy scored 5.0 out of 10 across our 11 fixed criteria. Three red flags were identified: no clear mechanism for users to request data deletion, GDPR/CCPA handling not clearly stated (only referenced for paid-tier users), and user content may be used to develop and improve AI models. The policy does address retention periods, stating extension activity data is kept only as long as reasonably necessary.

Infrastructure: Merlin's extension communicates with getmerlin.in (first-party) alongside google-analytics.com, linkedin.com, and x.com. The data flow suggests standard analytics and social sharing integrations.

For business use: The tiered compliance model — where security guarantees only apply to paid users — is unusual and creates a two-class system. Without independently verifiable certifications, Merlin's security claims cannot be relied upon for regulated industry use.

Bottom line: Merlin's security posture is in the lower tier among the extensions we scanned. The privacy policy's tiered compliance claim (paid users get SOC 2/GDPR/ISO, free users do not) is a red flag in itself. The policy score of 5.0/10 and three red flags — no deletion rights, unclear GDPR handling, and AI training — compound the concern. Users handling sensitive data should prefer extensions with independently verified certifications.

Is Merlin safe to use? Merlin claims SOC 2/GDPR/ISO benefits primarily for paid users — a tiered compliance story we treat as a caution signal because free-tier guarantees are weaker and claims were not independently verified at scan time. Privacy policy scored 5.0/10 with red flags for deletion clarity, GDPR/CCPA clarity, and AI training.

Is Merlin for Chrome safe for business? Not as a default for regulated work. Prefer extensions with independently published audit reports and clear, tier-agnostic data processing terms. Casual personal use is a user judgment call after reading the permission and policy sections above.
