Lumin review

Lumin is designed around Google Drive: it says your files stay in Drive, with encryption at rest and in transit, and that Lumin does not store or move them to external servers. Lumin for Chrome and Google Workspace integrations put the editor where Drive users already work. The editor adds text boxes, shapes, images and freehand drawing, highlights text, edits the raw text of a PDF, rearranges, merges, splits and deletes pages, adds fillable fields, redacts content and searches scanned text. Lumin counts a document as completed once you share, download, print or sync it. The free plan covers 3 documents a month, Starter costs $9 a month for 10 documents, Pro costs $19 a month per team for 200 documents team-wide plus 5 agreements, and Business at $99 a month adds domain control, enforced Google sign-in and connectors for Slack and OneDrive. A library of 5,000+ free forms helps with paperwork. The document caps make it less suited to heavy editing.
