Claude, Gemini, Perplexity…
side-by-side comparison
You're Juggling AI Tools. Helena Brings Them Together.
ChatGPT for writing, Claude for analysis, Gemini for search, Perplexity for research — every task needs a different tab, a different subscription, a different context window. You lose focus, lose context, and waste time copying between services.

Feedback From Real Users
I was paying for ChatGPT Plus and Claude Pro separately. Helena lets me use both through API keys for a fraction of the cost.
The side-by-side comparison is incredible. I ask the same question to Claude and ChatGPT and pick the better answer in seconds.
I use Helena daily while coding on GitHub. Having Claude right there in a sidebar saves me 20+ context switches a day.
My team was split on ChatGPT vs Claude. Helena solved that debate — now everyone uses both through one interface.
