The record

Product: MailRovers is an open-source, local-first desktop email client for Gmail.
Mail workflows: It supports browsing cached labels and conversations, offline reading, search, composing, replying, local drafts, sending, and mailbox changes.
AI features: It can summarize conversations and stream AI-assisted reply suggestions for user review.
AI provider: Users provide an OpenAI-compatible API base URL, model identifier, and API key.
Integrations: Gmail is its sole mail provider, and the app connects directly to Gmail without a MailRovers-hosted application server.
Local storage: Mail data and application data are stored locally using SQLite, and synchronization runs while the desktop app is open.
Credential security: Gmail refresh tokens and AI API keys are encrypted with Electron safeStorage before SQLite persistence and are kept out of the renderer.
AI data handling: The app sends only messages needed for the requested AI operation, and AI cannot send mail or perform mailbox actions automatically.
Email HTML: Email HTML is treated as untrusted content in a sandboxed frame that blocks scripts and navigation.
Availability: The project says MailRovers is alpha software, targets macOS, must be built from source, and is not ready for a primary or business-critical inbox.
Notable limits: Windows, Linux, and non-Gmail providers are unsupported, and synchronization runs only while the app is open.
Distribution: The project says it has no signed, notarized, or automatically updating public release.
License: MailRovers is available under the MIT License.
Maker: The README identifies MailRovers as a project from Rinhelp, described there as an AI support tool.
