Deep Dive: Switching from TextCortex to Witsy

Trade-offs, installation & data architecture

The Catch vs TextCortex

What you trade away

Its experts and document repositories are flexible, but it lacks TextCortex's integrated browser knowledge bases, collaboration, and turnkey onboarding.

Installation

How to deploy Witsy

Download a desktop binary from GitHub Releases; macOS also supports `brew install --cask witsy`

Day-2 Operations & Setup

What it takes to run

It is BYOK unless you install Ollama and a local model; system-wide commands also need OS accessibility permissions

Data Ownership

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

Build vs Fork Verdict: YES (the core loop fits in a weekend)

Why fork Witsy instead of vibe-coding a TextCortex clone?

TextCortex's solo core is compact: build a private AI writing workspace workspace that sends user text to one chosen model, stores versions, applies reusable instructions, and exports Markdown. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on model, data, workflow.
