# MARKLINE > AI content transparency for brands, agencies and publishers — EU AI Act Article 50 readiness. > Product = MARKLINE; legal/commercial entity = Vertexi5. > Not legal advice. We do not sell guaranteed legal compliance. > No Code-of-Practice alignment or certification claims. ## What it is MARKLINE by Vertexi5 helps UK/EU-facing brands, agencies and publishers build readiness evidence — marking, disclosure playbooks and counsel-ready packs — for Article 50 transparency. We map provider vs deployer roles, inventory generative workflows, and ship playbooks and ops. Evidence for counsel — not solicitor advice; not a compliance certificate. ## Who it is for (ICP) Brands, creative agencies and publishers shipping AI-assisted text, image, audio or video to EU audiences (UK firms with EU audiences included where scope applies). ## Timeline (high level — claims C1–C2) - Art. 50 transparency obligations have applied since 2 August 2026. - For generative systems on the market before 2 Aug 2026, Art. 50(2) machine-readable marking grace ends 2 December 2026. - Deployer duties (e.g. deepfakes / certain public-interest text) are generally not deferred by that grace. ## Offers (indicative bands) 1. Compliance Sprint — £28k–£45k, 10–20 working days (map, inventory, risk register, playbook, tech plan, board one-pager). 2. Continuum — £1.2k–£4.5k/mo (beta waitlist; ongoing ops / attestation rhythm — readiness artefacts, not CoP alignment). 3. Agency Desk — £3k–£8k/mo (agency intake QC, label checklist, client disclosure copy). ## Integrity (banned claims) - Not legal advice; not a law firm. - No guaranteed compliance or regulatory clearance. - No Code-of-Practice / CoP alignment / presumption of conformity via MARKLINE. - No invented market-size claims; public claims live in CLAIMS.md. - Footer on every public asset: MARKLINE by Vertexi5 · Not legal advice ## Contact MARKLINE by Vertexi5 Email: markline@vertexi5.com ## Links - Home: https://markline.vertexi5.com/ - Sprint: https://markline.vertexi5.com/sprint.html - Continuum: https://markline.vertexi5.com/continuum.html - Agency Desk: https://markline.vertexi5.com/agency.html - About: https://markline.vertexi5.com/about.md - Claims: https://markline.vertexi5.com/CLAIMS.md - Full agent brief: https://markline.vertexi5.com/llm-full.txt Optional fuller summary for RAG / agents: see llm-full.txt
