Best chat & LLM AI tools — how to compare
Most “best AI chatbot” lists are affiliate score sheets. Use this checklist instead: match the tool to the job, check free-tier limits, and keep a human verification bar for anything public.
Comparison checklist
- Job fit: drafting, coding, research, or everyday Q&A
- Free vs paid limits (messages, models, file uploads)
- Whether answers show sources you can open
- Data retention / training on your chats
- Multimodal needs (images, PDFs, voice)
- Whether local/offline is required

FAQ
What is the best free AI chatbot?
It depends on the job. Free ChatGPT, Gemini, and DeepSeek tiers are strong for everyday drafting; Claude often wins on careful writing; Perplexity wins when you need linked sources. Run the same real task on two tools before you commit.
ChatGPT vs Claude vs Gemini — which should I use?
Use ChatGPT for broad everyday tasks and plugins, Claude when you want careful long-form and coding help, and Gemini when you live in Google Workspace or need multimodal drafts. Keep a verification bar for anything you publish.
When should I use a local LLM instead?
When privacy, offline use, or predictable cost matters more than frontier quality. Compare with our Local LLM vs API guide and tools like Ollama or LM Studio.
