Deep Dive: Switching from QuillBot to Witsy
Trade-offs, installation & data architecture

It can run rewrite commands anywhere, but results depend on prompts and models rather than QuillBot's purpose-built paraphrase controls and writing-tool suite.
How to deploy Witsy

What it takes to run
It is BYOK unless you install Ollama and a local model; system-wide commands also need OS accessibility permissions
Where your data lives

Why fork Witsy instead of vibe-coding a QuillBot clone?
A paraphraser/summarizer/grammar wrapper over an LLM and LanguageTool is easy to build; the paid app wins on UX, extensions, plagiarism workflows, and bundled tools.
