FlyMSG is a free AI-powered text expander and writing assistant built as a browser extension by Vengreso, a sales productivity company founded in 2017 by CEO Mario Martinez Jr. It helps users create reusable shortcuts ('FlyCuts') and generate AI-written messages directly inside LinkedIn, email, and other web apps.
FlyMSG offers a genuine freemium model, not a time-limited trial. The free plan includes core text-expansion features and a limited amount of AI generation, while paid tiers unlock larger template libraries, more AI usage, and team features.
FlyMSG is distributed as an extension for Google Chrome and Microsoft Edge. Because it works inside the browser, it functions across virtually any web-based application, including LinkedIn, Gmail, Outlook on the web, and most CRMs.
FlyMSG combines traditional text expansion with built-in AI generation and a strong focus on LinkedIn and sales prospecting workflows. TextExpander leans more toward general-purpose, cross-platform expansion, while Magical emphasizes data autofill. FlyMSG is most differentiated for sales, recruiting, and social-selling use cases.
Vengreso markets a savings of roughly one hour per day, or about 30 hours per month, based on heavy users who replace repetitive typing with FlyCuts and AI-generated drafts. Actual savings depend on how much repetitive writing a user does â high-volume sellers and recruiters tend to see the largest gains.
