The Claude vs ChatGPT Split
Claude excels at long-form, research-heavy writing. ChatGPT is better for rapid iteration and punchy rewrites. Use Claude for the skeleton of your essay. Use ChatGPT to make it snappier. Combine them.
Growing Your Newsletter With AI
Beehiiv's growth tools (referral programs, viral loops) are powerful. But your best growth tool is consistency. AI makes consistency possible. When you can write a 2000-word essay in 2.5 hours instead of 5, you actually hit publish on schedule. That's when growth happens.
