Deep Dive: Switching from HyperWrite to Witsy
Trade-offs, installation & data architecture
What you trade away
Its system-wide commands are powerful, but they are action-based rather than HyperWrite's continuous inline suggestions and browser-aware autocomplete.
How to deploy Witsy
Download a desktop binary from GitHub Releases; macOS also supports `brew install --cask 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
Conversation 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
Why fork Witsy instead of vibe-coding a HyperWrite clone?
The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For HyperWrite, draft, rewrite, and answer questions using user-selected context and personal templates. The hard boundary is browser presence, personalization history, and proprietary agent workflows, plus workflow, data, and model tuning.
