How to Choose an AI Assistant

Cloud vs self-hosted. ChatGPT and Claude run on their providers' servers — zero setup, always updated. OpenClaw and Moltbot run on your hardware — full privacy, no subscription, but you manage the infra.

Context window matters. Claude Pro offers 200K tokens — enough for entire codebases or books. ChatGPT Plus sits at ~128K. Match the context size to your actual workload; don't overpay for capacity you won't use.

Tool integrations. The best AI assistants now connect to your actual tools — email, calendar, Slack, CRM. If 80% of your day is in specific apps, an assistant that integrates there beats a more powerful one that doesn't.

Multimodal capabilities. Need image generation? ChatGPT Plus. Need vision analysis? Claude Pro and ChatGPT both handle it. If you work heavily with images, diagrams, or documents, skip text-only assistants.
