Frequently asked questions
What is the best free alternative to ChatGPT Plus?
ZeroLimitAI has a 3-day free trial with no credit card, running on the best free AI models available right now (e.g. Google's Gemma), re-ranked daily. After the trial, the Chat plan is $19 a year, against $240 a year for ChatGPT Plus. You get open models, not OpenAI's own.
Is there an AI assistant with no monthly subscription?
Yes. ZeroLimitAI Lifetime is $99 once, with no recurring payment; it includes the full app and the developer API (5,000 calls a day). If you only want the chat, the Chat plan is $19 a year. ChatGPT Plus, Claude Pro and Gemini Advanced are about $240 a year each.
Which models does ZeroLimitAI use?
Only free models. ZeroOptimize™ ranks them every day on published benchmarks and LM Arena votes and sends each message to the best one that is answering at that moment. The free catalog changes week to week; the live list is at zerolimitai.com/leaderboard.
How does ZeroLimitAI compare to ChatGPT, Claude, and Gemini?
ChatGPT, Claude and Gemini give you each company's own frontier models for about $20 a month. ZeroLimitAI does not include those models: it runs on the best free models available, picked automatically for each message, for $19 a year. For everyday writing, research and code questions that is often enough; for the hardest tasks the paid frontier models are stronger.
