## 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

## Vibe Shift

Vibe Shift solves a very specific communication problem: the message you have already rewritten five times before hitting send. It installs as a Slack app and turns tone adjustment into a single slash command. Type your message as you normally would, decide whether it should read professional, casual, friendly, concise, cheerful, or encouraging, and Vibe Shift returns a polished version instantly, right where you type.

A second workflow, /reply, reads the recent history of a channel and drafts a context-aware response in your chosen tone, which is useful in busy threads where a well-composed answer matters but time is short. To keep output consistent, you can define custom writing preferences that apply to every rewrite, so Vibe Shift keeps your voice across conversations.

The app is designed to feel invisible. It works on desktop and mobile across channels, direct messages, and threads, and your text is never saved to a database or used for training, only held briefly in memory so rewrites can be regenerated. Pricing is straightforward, with a free allowance for every workspace and Pro and Team plans for individuals and teams that write a lot.

**Pricing & Plans:** Free to start with 50 rewrites and 5 replies per workspace each month and no credit card required. Pro is $9.99/month for 300 messages, and Team is $34.99/month for 3,000 messages with priority support.

- **Six selectable tones:** Rewrite any Slack message in professional, casual, friendly, concise, cheerful, or encouraging tone with a slash command.
- **Context-aware reply generation:** Drop /reply in a channel and Vibe Shift reads recent conversation history to draft a context-aware reply automatically.
- **Custom writing rules:** Set personal writing preferences that apply to every rewrite so the output consistently sounds like you.
- **Instant, in-Slack workflow:** Results appear in seconds inside Slack with no app switching or copy-pasting, on desktop and mobile across channels, DMs, and threads.
- **Privacy by default:** Messages are never stored in a database or used for training and are held in memory for at most 24 hours to allow regeneration.

**Strengths:** Rewrites messages in seconds without leaving Slack; Six preset tones plus custom writing rules keep your voice consistent; Context-aware replies save time in busy channels; Privacy-first design with no message storage or training use

**Limitations:** Requires installing a Slack app to get the full workflow; Free tier is capped at 50 rewrites and 5 replies per workspace each month; Focused on tone and replies rather than long-form writing or editing
