AI Tool Decision Hub
Choose AI tools by workflow, not hype.
This hub turns the site's AI tool archive into a global decision surface for builders, researchers, creators, and AI enthusiasts. Use it to compare coding agents, general agents, AI search, knowledge tools, local LLM setups, image tools, and practical calculators.
How this hub should be used
- Start with the job, not the brand. Coding, search, writing, RAG, image generation, and local deployment need different tools.
- Prefer tools that expose workflow evidence: files changed, sources used, traces, tests, costs, and failure states.
- Use public rankings as hints, then test your own tasks with your own data and constraints.
- For sensitive work, check data retention, admin controls, model provider, deployment region, and export options before uploading anything important.

Translate tokens into pages, words, and rough document scale before choosing a model.
Model selector
Choose models by writing, coding, RAG, local deployment, image, and video scenarios.
Local LLM GPU fit checker
Estimate whether a model can fit your local GPU memory under common quantization choices.
Prompt generator
Turn goals, input materials, tone, and output format into a usable prompt template.
Agent stack selector
Compare Dify, n8n, LangGraph, MCP, and custom agent stacks by workflow needs.
RAG chunk size calculator
Pick chunk size, overlap, and retrieval count based on document type and context window.
Next layer: English deep guides
The deep guide archive is still largely Chinese. This page now gives global readers a usable map first, then sends them into the deeper archive when they want more detail. The next upgrade should translate the highest-search guides into full English pages.
