## RewriteBar

RewriteBar solves a very practical problem for Mac users: most writing assistants live in their own editor or browser tab, while real writing happens everywhere — Slack threads, email clients, Google Docs, Notion, Word, WhatsApp and code editors. RewriteBar instead sits at the system level. It grabs your current selection, sends it to a language model with the action you picked, and pastes the result straight back over the original text, so you never leave the app you are working in.

Out of the box it ships with a library of ready-made actions: grammar and spelling fixes that understand full-sentence context, rewriting for clarity, simplification, tone adjustment, humanizing AI-sounding text, summarising to bullet points, fixing broken JSON, converting to title case, turning formal German or French into the informal register, and translation across 500+ languages. On top of those presets you can build your own commands, insert variables, and chain several actions into one workflow — expand, emoji-fy, translate and summarise in a single pass. A side-by-side diff view lets you check exactly what changed before you accept it.

Flexibility is the other selling point. You can bring your own API key from OpenAI, Anthropic, Google, Groq, Mistral, DeepSeek, OpenRouter and dozens more; subscribe to the RewriteBar Gateway to get access to 70 models without managing keys; or run everything through a local model with Ollama, LM Studio or Apple Intelligence for maximum privacy. The app is only around 25 MB, is natively built for macOS, integrates with PopClip, and never stores your text on RewriteBar's servers.

**Pricing & Plans:** Freemium with a free trial, then one-time licences. Try it free with 35,000 credits and no credit card; Standard is $29 one-time (1 device, 35,000 credits, BYOK and local models); Pro is $59 one-time (3 devices, 1 year of RewriteBar Gateway with 3 million monthly credits). Extra devices cost $19 one-time, and the RewriteBar Gateway can be bought separately for $40 per year. Refunds available within 14 days.

- **Works in any application:** RewriteBar captures the selected text system-wide and pastes the improved version back, so it functions in Chrome, Google Docs, Word, Slack, Notion, VS Code, email clients and more.
- **Preset and custom AI actions:** Use built-in commands such as fix grammar, simplify, humanize, summarise, title case, fix JSON, create ASCII art or translate, or author your own commands with variables and prompt libraries.
- **Chain actions into workflows:** Combine several actions to transform text step by step — for example expand, add emojis, translate and rewrite a title in one flow.
- **Cloud or fully local models:** Bring your own API key from major providers, use the RewriteBar Gateway, or keep everything on-device with Ollama, LM Studio, oMLX or Apple Intelligence.
- **Diff view and shortcut-driven flow:** Compare original and rewritten text line by line or word by word, and trigger everything from keyboard shortcuts or PopClip integration.

**Strengths:** Genuinely app-agnostic thanks to system-level text capture; One-time licence options with no mandatory subscription; Strong privacy story with local model support and no server-side text storage; Very small footprint (~25 MB) with native macOS performance

**Limitations:** macOS only, with no Windows or Linux version; Some actions require configuring your own API key, which adds setup work and separate provider costs; Advanced workflows and the 70-model gateway are gated behind the Pro or Gateway plans

## Thesaurus – Powered by AI

Thesaurus – Powered by AI rethinks the classic reference tool for the age of language models. Instead of returning only the rigid synonym lists of a traditional dictionary, it accepts ordinary language as input — turns of phrase, slang, acronyms and partial thoughts — and proposes richer alternatives that fit the intent behind what you wrote.

The app lives in a compact Mac window that can be pinned as a floating panel above other apps, so it stays within reach while you write in your editor, browser or chat window. Its results are presented in a leather-textured pane that can be customized across four visual styles, giving the tool a distinctive, desktop-native feel rather than a browser tab.

A major part of version 2.0 is flexibility in how the AI runs. The app can use on-device Apple Intelligence models so lookups work offline without sending text anywhere, and it can also draw on fast cloud models such as Cerebras for quicker responses. Reviews praise the design and everyday usefulness while noting that the local model can feel slower than the cloud option, and that antonyms are not yet included.

**Pricing & Plans:** Free. The app is listed on the Mac App Store at no cost, with no subscription required. Cloud model usage depends on the model provider arrangements built into the app.

- **AI-powered synonym search:** Enter a single term, a phrase, an acronym or slang and get a diverse set of alternative words and similar expressions instead of a fixed dictionary list.
- **On-device and cloud models:** Switch between local Apple Intelligence models for offline private lookups and faster cloud models such as Cerebras for lower-latency results.
- **Pinnable floating window:** Keep the app as a small floating panel above your other windows so the right word is always a glance away while you write.
- **Four customizable window styles:** Choose from multiple leather-textured skins to match the look of your desktop setup.
- **Tiny footprint:** A roughly 14 MB download for macOS that starts quickly and stays out of the way.

**Strengths:** Natural-language input handles phrases, slang, acronyms and idioms, not just single words; On-device Apple Intelligence support means lookups can work offline; Beautiful, minimal Mac-native interface with four customizable styles; Free to download with no subscription

**Limitations:** Local on-device model can respond noticeably slower than cloud models; No dedicated antonyms function, a gap several reviewers have flagged; Requires a recent version of macOS to run
