Tips for better answers
Get the most out of the free assistant.
1
Be specific
Give context, constraints and a desired format. 'Write a 100-word LinkedIn post about remote work for a software engineer' beats 'write about remote work'.
2
Ask follow-ups
The conversation keeps context, so refine and drill down: 'now make it shorter', 'add a third option', 'in French'.
3
Verify important facts
Free models can be confidently wrong. Double-check numbers, quotes and code for critical decisions.
AI Chat — FAQ
Is this really free?
Yes. The chat runs on the free Google Gemini API tier. There are no credits, subscriptions or hidden fees — usage is limited to a few messages per minute to keep it fair for everyone.
What can I use it for?
Writing, coding, learning, translation, brainstorming, summarizing and more. It's a general assistant that also knows PromptHub's prompt library and tools.
Is my conversation private?
Your messages are sent to the LLM to produce a reply and are not stored or indexed by PromptHub. The conversation history lives only in your browser session.
Why is there a message limit?
The free Gemini tier allows roughly 15 requests per minute per key, shared across all PromptHub users. A short per-user limit keeps the service fast and free for everyone.
How is this different from the specialized tools?
The specialized tools (Writer, Code, Career, Social, Learn) are optimized for one task with structured forms. The chat is open-ended — use it to explore, then switch to a tool for a polished result.
