Section 01
Graphlink is a desktop-based graphical AI workspace built with Python and PySide6, designed to address the limitations of mainstream linear chat interfaces in complex reasoning tasks. It replaces linear conversations with a node canvas, supporting branching reasoning, multi-AI provider orchestration, and a rich plugin ecosystem, enabling local-first data storage and offline work capabilities.
Section 02
Most current mainstream AI interaction interfaces are linear chat modes, which struggle to meet needs like branch exploration and scheme comparison in complex reasoning tasks. Graphlink's design philosophy is based on the insight that 'complex work does not proceed in a straight line', upgrading AI interaction to a visual node canvas. This project is the second-generation evolution of Graphite; it was renamed Graphlink to avoid name confusion and highlight the core of connected reasoning.
Section 03
Graphlink uses Python 3.10+ as its core runtime, with the desktop UI based on the PySide6/Qt framework. Local models are integrated via Ollama, and the API supports OpenAI-compatible endpoints and Google Gemini. Data persistence uses SQLite + JSON serialization; all data is stored in the .graphlink folder in the user's home directory (including chats.db and session.dat), ensuring local-first and offline work.
Section 04
Built-in node types include core elements like chat, code, document, image, and thinking, as well as auxiliary elements like notes and frame containers. The plugin system is rich: Workflow Architect generates execution plans, Branch Lens compares branch differences, Quality Gate performs production readiness reviews, Code Review Agent conducts structured code reviews, Gitlink manages repository context, Py-Coder assists with coding, and Execution Sandbox runs Python code in isolation.
Section 05
It supports local Ollama models (default qwen3:8b for chat, etc., deepseek-coder:6.7b for code diagrams) and API modes (OpenAI/Gemini). Task models can be flexibly configured to balance privacy, cost, and performance. Application scenarios include research analysis (parallel branch comparison), code development (full-process visualization), creative writing (multi-plot exploration), decision support (systematic option evaluation), etc.
Section 06
It supports exporting to formats like plain text, Markdown, HTML, Python scripts, Word, and PDF, and importing multiple file types. Local SQLite storage lays the foundation for collaboration (database files can be shared). For privacy, all data is stored locally; API keys and others are saved in session.dat, and it is recommended to migrate to stronger credential storage solutions for sensitive scenarios.
Section 07
Graphlink is in the active development phase; the codebase is transitioning from Graphite, and some modules still contain old names. The development strategy prioritizes Windows, with core code being portable. Future plans: improve automated testing, unify configuration processes, enhance secure storage, expand the plugin ecosystem; community contributions are welcome, with CONTRIBUTING.md and SECURITY.md provided to guide collaboration.
