Be specific — the more context you give, the better the result. 2. **Let the AI work** — AI Chat Assistant streams the response back as it is generated, so you can start reading immediately instead of waiting for the whole answer. 3. **Refine or export** — Ask follow-up questions to narrow the result, then copy it or download it. No API key and no account are required. ## Use cases - Drafting a first version quickly when the blank page is the hard part - Summarising a long document down to the points that matter - Rewriting text for a different audience, tone or reading level - Students, marketers and developers who want an AI assistant without paying for a subscription ## Tips - Say who the output is for and how long it should be. Specific constraints produce far better results than an open request. - Treat the first answer as a draft and refine it with follow-ups rather than re-typing the whole prompt. - Always check facts, figures and citations yourself — a language model can state something wrong with complete confidence. ## Common problems - **The answer stopped part-way through** — The response hit its length limit. Ask it to continue, or split the request into smaller parts. - **The result is generic or off-target** — The prompt left too much open. Add the audience, the format, the length and an example of what good looks like. - **The tool declined the request** — The prompt crossed a safety boundary of the underlying model. Rephrase it, stating the legitimate context and purpose. ## FAQ ### Is AI Chat free? Yes — 10 free server messages/day.
