FAQ

How does the A/B testing work?
You create a campaign, add prompt variants with different wording or models, then send identical inputs through each variant. PromptSplit records token usage, cost, and your quality scores so you can compare results side by side.
Which AI models are supported?
We support OpenAI (GPT-3.5, GPT-4, GPT-4o), Anthropic Claude, Google Gemini, and any OpenAI-compatible endpoint. Bring your own API keys — we never store them.
Can I cancel my subscription anytime?
Yes. Cancel from your account dashboard with one click. You keep access until the end of your billing period and your data is exportable at any time.
