Finding information
Gemini can be useful when the task benefits from Google search context. ChatGPT can also help when search or browsing features are available.
For current facts, ask for sources and open them yourself. Do not rely on model memory.
Synthesizing sources
ChatGPT is often strong at turning scattered notes into a brief, comparison table, decision memo or outline. Gemini can help discover and summarize Google-connected material.
Use one model to gather or summarize and the other to challenge assumptions.
Verification workflow
Keep a source log, check dates, prefer primary sources and mark claims that need verification. For medical, legal, financial or policy topics, use official sources and expert review.
