Company profile
researched Aug 2026Maestro Labs develops a suite of AI productivity assistants that operate inside existing email, calendar and meeting tools rather than as standalone applications. Its main products are MailMaestro, an AI email assistant available as an Outlook add-in via the Microsoft Marketplace and as a Gmail extension via the Chrome Web Store, and TeamsMaestro, an AI meeting note taker distributed through the Microsoft Teams Store. The portfolio also includes CalMaestro, an AI scheduling assistant for Teams, and WordMaestro, a Microsoft Word add-in.
MailMaestro's features include drafting emails from short instructions with a choice of language, tone and length (returning three draft options), improving or rewriting existing drafts, generating context-aware replies from email threads and attachments, summarizing single emails or entire threads, automatic tagging of email by priority and intent for inbox triage, detection of action items and deadlines with automated reminders, reusable "magic templates", and keyword shortcuts for inserting data such as phone numbers or LinkedIn profiles. Support is offered for more than 20 languages. TeamsMaestro joins scheduled meetings automatically or can be added and removed during Microsoft Teams calls, captures the live transcript, and emails a recap covering purpose, takeaways, a detailed summary and action points, with action items assigned to participants.
The company positions security and compliance as a core part of the offering, stating data encryption in transit and at rest, optional zero-day data retention and PII obfuscation for enterprise clients, SOC 2 Type II, GDPR and HIPAA compliance (with BAA on request), Google verification, CASA Tier 2 verification, and attestation by Microsoft and Google. It maintains a Security Center, Trust Center and data privacy policy.
