Overview

Socials:

Manzoni is an AI-powered word processor for MacOS that prioritizes minimalism and privacy.

Most AI writing tools stream your text to remote servers. This one doesn’t. It runs fully on your machine — no data ever leaves your device.

Get assistance from open-source LLMs integrated into a custom writing interface without sharing your words with clouds that enforce unclear privacy policies.

It’s fast and accurate for writing and polishing text locally. Some models were fine-tuned specifically for writing tasks. (Please note that text generation speed and quality may vary depending on your laptop's hardware and model size).

If you care about control over your data, this tool is for you!

Key features:
🧘 Clean, distraction-free UI: minimal design, dark and light modes, always easy on the eyes.
💡 Inline prompt bar: press spacebar to brainstorm ideas, get suggestions, and overcome writer’s block without breaking the flow.
✨ Inline edits: select text and ask AI to check grammar and polish content instantly, no copy-pasting between tools.
📝 Prompt templates: jumpstart writing with ready-made creative prompts that cover 35+ use cases without staring at the blank page.
🌶 Uncensored LLMs: pick from a curated list of open source, fine-tuned and uncensored LLMs that don’t sound boring or corporate.
⌨️ Markdown shortcuts: format text without leaving your hands from the keyboard.

Everything is powered by local AI models:
100% offline
No accounts
No tracking
No data leaves your device

All features available for free below 3 documents to try the full experience at your own pace and upgrade with a one-time purchase once it becomes part of your workflow.

🧩 TextWisely was born from a personal itch ⚠️ Sending numerous Emails and Slack messages daily, I found myself constantly switching apps and re-entering the same prompts into ChatGPT to refine my writing 💡 This inspired me to create TextWisely to boost writing speed, reduce context switching, and improve quality with instant text actions: → Grammar corrections → Email drafts → Structured writing → Tone changes → Translations ...and more 👉 It's a native macOS desktop app – shortcut-heavy for power users, but also click-friendly for those just starting out 🚀 Give it a try – Share your feedback and experience 👋 Edgar, creator of TextWisely
