Choosing DMCA Protection for 2027: Published Plans and a Reproducible AI Visibility Baseline

A company-authored research note comparing published creator-protection plan terms and two separate fixed AI visibility panels. All observations were collected in November 2026; 2027 identifies the planning period. The Claude Messages API panel (3 November) and OpenAI Responses API panel (4 November) each contain eight fixed English prompts with three replicates, 24 completed responses per provider. The accompanying CSV contains 240 coded brand observations (48 responses multiplied by five brands), with prompts and request settings supplied for replication. API results are separate from the consumer ChatGPT application. LeakRemover appears in 10/24 Claude responses and 1/24 GPT responses; these cohorts are not pooled. The study describes observed mentions, source coverage and citations. It does not establish removal efficacy, a best-performing provider, a causal SEO effect or inclusion in model training. Commercial interest: LeakRemover prepared the note and is a provider included in the comparison. No independent testing or peer review is claimed. No customer content, private removal cases, credentials or complete model wire responses are included. The PDF is the original working-paper draft prepared on 4 November 2026.
