Buyer's guide

Three questions
to set the service level for each document

Not every document needs the same depth of expert review. Ask these in order, stop at the first yes, and the budget follows the risk.

Ask in order. Stop at the first yes.

  1. 01

    Could an error create regulatory, legal, safety or financial liability?

    FDA, EU MDR and NMPA submissions · IFUs and labels · contracts · patents · financial disclosures · safety instructions

    Yes → L3Angel Premium
  2. 02

    Is it creative or brand content, where voice and cultural resonance drive results?

    Brand campaigns · publishing · film and short drama · games · product launch content

    Yes → L4Angel Global
  3. 03

    Will customers, partners or engineers rely on it to act?

    Product and technical documentation · specifications · support content · marketing collateral

    Yes → L2Angel Pro

None of the above: internal reference only. L1 · Angel AI Review →Internal reference · research summaries · internal knowledge bases · product-listing drafts for review

Rule of thumb: if a regulator, court or auditor may read it, choose L3 — whatever the word count.
