Pismo is a native AI writing assistant for Mac and Windows. Rather than living in a browser tab or extension, it runs as a desktop application and works on text in the apps people already use, including email clients, documents, messengers and browsers. The pricing page also lists iOS support.
The company is based in Luxembourg and describes the product as a single writing tool for everyday use. It improves writing, fixes errors, changes tone, summarizes and translates, and it aims to do all of this without sending users to a separate window.
Pismo operates in the background of the operating system. Users select text in any app, then trigger an AI action with a hotkey or the on-screen widget, which opens an AI overlay. This avoids copying and pasting text into a separate chatbot window, a point several reviewers on the site praise.
Processing happens in the cloud, so an internet connection is required. The company says it does not store or process the texts users work with, and that the app connects to the cloud only when AI processing is needed. Users can also bring their own OpenRouter key to choose models.
Pismo's built-in actions cover grammar and spelling fixes, smart rephrasing, tone adjustment from casual to professional, friendly or persuasive, summarization into bullet points, and shortening or lengthening text. Translation works to and from any language, and the company says it aims to preserve meaning rather than translate word for word.
Control features set it apart from simpler tools. Custom prompts can be created, saved and organized, then launched by custom hotkeys. The Bring Your Own Key option connects to OpenRouter. The interface is localized in ten languages, including German, Spanish, Japanese and Hindi.
