ChatGPT for Mac alternative
OpenAI’s desktop app with frontier models, memory and meeting recording—versus Tyne’s on-device dictation and an encrypted vault you control.
The ChatGPT Mac app gives you OpenAI’s models in a desktop window and an ⌥ Space chat bar. It offers Memories, Record mode for meetings (up to four hours, on paid plans), and an opt-in Computer History feature on Pro, Business and Enterprise.
Requests are processed on OpenAI’s servers. Computer History logs interaction events such as clicks, typing and app switches (no screenshots or audio), processes them on OpenAI’s servers, and saves the resulting memories on your Mac as plain Markdown files.
Conversations, recordings and Computer History events are processed by OpenAI in the cloud.
OpenAI documents that Computer History memories are stored on your Mac as unencrypted Markdown.
Voice input is documented for writing prompts inside ChatGPT, not for typing cleaned text into any app.

On Turbo, Balanced mode is the default. Loom Turbo can process relevant note, document or screen content for supported answers and reports. Local Only keeps new request content on your Mac.

Request Beta AccessQuestions
Yes. Tyne’s Free plan includes unlimited on-device dictation with no word cap. Tyne is currently invite-only, so you need to request beta access before installing it.
Yes. After the speech models are installed, dictation and cleanup run on your Mac. Local Only keeps new AI request content on your Mac; live web search and Loom Turbo cloud answers require a connection.
No. Raw dictation and meeting audio are transcribed on your Mac and are not uploaded. On Turbo in Balanced mode, selected text or an image can be sent for a supported cloud answer, but raw audio and the full vault stay on your Mac.
ChatGPT for Mac is a strong choice if you value access to openai’s most capable models and agent features. Tyne is designed for people who want system-wide Mac dictation plus encrypted local notes and a document workspace.
