About GhostReply
GhostReply is a macOS Terminal application that auto-sends AI-generated iMessage replies using your personal texting style. It reads your message history locally to build a style profile for each contact, then watches chosen conversations and writes responses. The tool runs entirely on your Mac, sending relevant context directly to Groq via your own API key-no data passes through GhostReply servers.
Review
GhostReply takes a narrow, single-purpose approach to AI messaging. It doesn't try to be a full chat client or productivity suite. Instead, it sits in Terminal, watches iMessage, and replies when you don't. The setup is manual and the interface is text-based, which tells you a lot about who it's built for.
Key Features
- Per-contact style learning. GhostReply reads your local message history during setup and stores a separate profile for each person, so replies match how you actually text that individual.
- Conversation selection. You choose whether to monitor a single contact or all one-to-one chats. Group chats are skipped automatically.
- Local context routing. Message context goes from your Mac directly to Groq using your API key. GhostReply's servers never see your conversations.
- Manual reply override. If you respond to a message yourself, GhostReply steps back and doesn't send an AI-generated reply.
- Terminal-based control. The process runs in a Terminal window. Closing that window stops the auto-replies immediately.
Pricing and Value
GhostReply costs $4.99 as a one-time payment. The latest release includes hosted AI, so you can install with a single command and try 10 replies free without creating an external AI account. After those free replies, the one-time purchase applies. There is no subscription. Earlier versions required users to bring their own API key; the hosted option is new to this release.
Pros
- One-time $4.99 payment with no recurring charges.
- Message history and style profiles stay on your Mac rather than on external servers.
- Stops replying the moment you close the Terminal window or reply manually.
- Skips group chats by design, reducing unwanted automated messages.
- Hosted AI option removes the need to configure an external API key.
Cons
- Requires comfort with Terminal; there is no graphical interface.
- Limited to iMessage on a single Mac-no cross-device or cross-platform support.
- Not well suited for users who want granular control over reply timing, tone adjustments, or per-message approval before sending.
GhostReply fits a specific workflow: someone who uses iMessage heavily on a Mac and wants to offload quick replies without handing conversation data to a third-party service. The Terminal-only interface and single-machine limitation keep the scope tight. It won't replace a full messaging assistant, but for the $4.99 one-time cost, it does the one thing it claims-auto-replying in your style until you tell it to stop.
