A browser sidebar that reads the page, rewrites the selection, and saves custom actions; your local model does the thinking.
licenseMIT
runson your machine
installInstall the extension from the Chrome, Edge or Firefox add-on store
enginesOllama, Chrome AI (Gemini Nano) and OpenAI-compatible local endpoints such as LM Studio or llamafile
dataChats, settings and other extension data are stored in the browser's local storage; only the optional share feature contacts the project's server
the catch vs WordtuneIt can rewrite selected browser text, but it lacks Wordtune's polished inline choices, fluency tuning, and consistent shorten-expand workflow.
setupThe extension installs cleanly, but it still needs a running local model endpoint and browser-to-localhost connectivity

Select text anywhere, hit a hotkey, and fix, rewrite, summarize, or obey a custom instruction without opening another tab.
licenseGPL-3.0
runson your machine
installUse the portable Windows ZIP or macOS DMG; Linux currently runs from source
enginesGemini, native Ollama and any OpenAI-compatible cloud or local endpoint on Windows/Linux; the macOS port also supports OpenAI, Anthropic, Mistral, OpenRouter, Gemini, MLX and Ollama
dataAPI keys and configuration stay on the device; the app does not retain writing or logs, and selected text goes only to the chosen cloud provider unless a local model is used
the catch vs WordtuneIt is close for hotkey rewrites, but it does not match Wordtune's polished inline alternatives, sentence controls, and cross-device hosted consistency.
setupYou must supply an API key or install a local model; macOS needs Accessibility permissions, while Linux installation and Wayland support remain rough

System-wide selected-text commands, reusable experts, a scratchpad, and document context; bring the model and skip the subscription.
licenseAGPL-3.0
runson your machine
installDownload a desktop binary from GitHub Releases; macOS also supports `brew install --cask witsy`
enginesOpenAI, Anthropic, Gemini, xAI, Meta, Ollama, LM Studio, Mistral, DeepSeek, OpenRouter, Groq, Cerebras, Azure and OpenAI-compatible endpoints, plus optional image, video, speech, search and MCP providers
dataConversation history, experts, settings and document repositories live in the local application profile; local files are indexed locally, while prompts and retrieved context sent to a cloud model leave the machine
the catch vs WordtuneIt can create rewrite commands, but Wordtune's immediate side-by-side sentence choices and editor integration are more focused and predictable.
setupIt is BYOK unless you install Ollama and a local model; system-wide commands also need OS accessibility permissions
