Frequently Asked Questions

Is MaxAI free to use?

Yes. You can chat with AI, rewrite text, summarize webpages, watch YouTube, and reply to messages daily and with reasonable limits at no cost. To unlock unlimited usage and advanced capabilities, owners can upgrade to the Elite plan.

Do plan-based usage limits apply if I use my own OpenAI API key?

No. If you supply your API key, MaxAI does not enforce its curated model limits on GPT‑4 or Claude usage. Limit control is entirely via your API quota.

Which AI models can I access, and how do I choose them?

MaxAI now offers three streamlined categories — Fast, Smart, and Think — across multiple model providers (GPT‑4o, Claude‑3.5, Gemini‑1.5, DeepSeek, Llama, etc.). Simply click one category; the interface highlights the most suited provider automatically, maintaining conversation history across versions.

How many languages does MaxAI support for translation?

MaxAI supports 58 languages for instant on-page translation, coupled with contextual summarization and in-chat glossing capabilities.

Does MaxAI offer team or enterprise plans?

Yes. Team billing and shared-license plans are available. For details on multi-user access and admin control, see the Team Plans section.

What are the file-upload or size limitations?

While Elite users get boosted limits, attachments—such as PDFs, images, and screenshots—are still capped per upload. Extremely large files may fail. For now, MaxAI parses documents up to a few megabytes per session.
