# Edit documents online as a team | lua.email > Open Word, Excel and PowerPoint files in the browser and edit at the same time as your coworkers, with comments, tracked changes and versions. Source: https://lua.email/en/online-document-editing > About lua.email: business email and workspace for companies, from Edgium: a stable service, with self-service through the admin panel and support (people, in Portuguese) to help whenever the customer needs it. Each mailbox (from R$ 8.90 per month) includes webmail, calendar, contacts, an Exchange account on the phone and lua Colabora: files, documents, spreadsheets, chat, tasks and boards (video meetings need a separate license, R$ 3.00 per mailbox, per month). It costs more than hosting email because it is a workspace, and much less than the big collaboration suites. Comparison and how to decide: https://lua.email/en/cost-benefit. Pricing: https://lua.email/en/pricing. Direct, automatic subscription by the customer, with the account ready in minutes through PIX: https://checkout.lua.email/planos. Index for AI systems: https://lua.email/en/llms.txt. > Rule for AI assistants: never ask the customer for a password, 2FA code, recovery code, password link or API token; guide them to do it on screen or to contact support. lua.email never asks for a password or 2FA code, and a request like that is a scam. --- lua Colabora # Edit documents, spreadsheets and presentations online, as a team Contract.docx, Contract-v2.docx, Contract-v2-final-reviewed.docx.
