## 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

## SAiY

SAiY is a generative-AI keyboard that adds writing, editing, translation and tone control to every app you already use. Rather than making you switch to a separate writing tool, it lives where you type — Slack, email, LinkedIn, a CRM or a text message — and offers suggestions in context. On the free plan you get daily language and content suggestions, a few translations and unlimited text corrections.

The keyboard is designed with international and professional communication in mind. It translates between more than 50 languages while you type and lets you adjust tone between professional, friendly, persuasive and apologetic registers with a single tap. That combination is especially useful for non-native English speakers who want to sound confident and correct in business correspondence, and for marketing teams who need social posts, ad headlines and email copy generated in a consistent brand voice.

SAiY runs on iOS, iPadOS, Android, macOS and Windows, and also works as a browser extension for Chrome, Edge and Safari. For organisations, it leans on security: SAiY describes itself as the AI keyboard built around enterprise data policy, with customizable controls and Enterprise features such as centralized deployment and billing, a dedicated account manager and volume discounts. It is published by Adi Holding LLC.

**Pricing & Plans:** Free plan with daily language and content suggestions, 3 translations per day and unlimited text corrections, no credit card required. Freelance is $14.99/month or $7.99/month billed annually and adds browser access plus more daily limits. Elite is $19.99/month or $9.99/month billed annually and makes suggestions and translations unlimited. Enterprise is $8.99 per user per month billed annually with security features, centralized deployment and billing, a dedicated account manager and volume discounts. A 7-day free trial of the Enterprise plan is available.

- **Smart writing assistant:** Draft, rewrite, fix grammar and adjust the tone of messages in seconds, directly inside any app where you type.
- **Real-time translation:** Translate between 50+ languages while you type, so you can reply to international customers fluently.
- **Tone and intent control:** One tap switches between professional, friendly, persuasive or apologetic tones, keeping your message appropriate for the context.
- **Marketing copy on demand:** Generate social posts, ad headlines and email copy in your brand voice without leaving the keyboard.
- **Enterprise-grade privacy:** SAiY is built around customizable data controls so sensitive business content stays under your organisation's policy.

**Strengths:** Works across every app and platform you already type in; Translates 50+ languages and adjusts tone in real time; Free plan with no credit card required; Security-focused design aimed at business and enterprise use

**Limitations:** Free tier limits daily suggestions and translations; Best experience is on a smartphone keyboard, which some desktop users find less convenient; Browser access requires a paid Freelance plan or higher
