Pismo

Pismo is a native desktop AI writing assistant for macOS and Windows that provides proofreading, rewriting, translation, and text generation across any application through a floating overlay widget and customizable hotkeys. It is designed for professionals, writers, multilingual workers, and students who want to improve their writing quality and productivity without switching between browser tabs or applications.

Key Features

• Grammar and spelling correction: Pismo scans selected text for errors and suggests fixes powered by AI, covering typos, grammar mistakes, and awkward phrasing.
• Smart rephrasing: Users can rephrase sentences to improve clarity, flow, and readability with a single hotkey press.
• Tone adjustment: The tool can adapt text tone from casual to professional, friendly, or persuasive depending on the target audience and context.
• Translation: Pismo translates selected text to and from multiple languages while preserving contextual meaning, supporting both writing improvement and international communication.
• Summarization: Long articles, emails, or reports can be condensed into concise bullet points or short summaries.
• Custom prompts: Users can create, save, and organize personalized AI instructions for repetitive tasks such as fixing code, replying to customer inquiries, or drafting social media posts. Prompts can be assigned to hotkeys for instant execution.
• Bring Your Own Key (BYOK): Through OpenRouter integration, users can connect their own API keys and choose from specific AI models instead of using the built-in defaults.

How It Works

Pismo runs as a background desktop application on macOS and Windows. Users select text in any application such as email clients, document editors, messengers, browsers, or IDEs and trigger Pismo via a hotkey or the floating widget. The AI overlay appears near the selected text, offering actions like improve, fix spelling, translate, summarize, or rephrase. Results replace the selected text or are copied to the clipboard, allowing the user to stay in their current workflow without context switching.

Use Cases

• Professional communication: Compose persuasive work emails, polish cover letters and resumes, and write compelling product descriptions with the right tone for each audience.
• Multilingual collaboration: Translate messages for global clients, understand foreign news and articles, and communicate with international colleagues without leaving the active application.
• Academic writing: Draft and refine essays, research papers, and reports with grammar correction and style suggestions that maintain academic standards.
• Content creation: Generate blog posts, marketing materials, and social media content faster with AI-assisted drafting and refinement.

Integrations

Pismo works in any desktop application including Microsoft Word, Slack, Discord, VS Code, web browsers, email clients, and design tools like Figma. It is not a browser extension but a system-level native app, meaning it functions consistently across all installed software.

Pismo offers a monthly plan at EUR 8 per month and an annual plan at EUR 75 per year (approximately EUR 6.25 per month, saving 22 percent).

Privacy and Security

Pismo is designed with a privacy-first architecture. The company states that it does not store or process user texts, connecting to cloud AI models only when processing is requested. It is GDPR compliant with servers located in Belgium (EU), and a Data Processing Agreement (DPA) is available upon request. Pismo does not sell or license user content to third-party data brokers.
