Prompt for Gemini AI
Act as a [role, described specifically -- e.g. "senior copywriter with 10 years in B2B SaaS" rather than just "writer"]. Task: [describe exactly what you need, including any constraints on length, tone, or approach]. Context: [any background information Gemini needs to do this well -- audience, prior attempts, what hasn’t worked]. Format the response as [desired format, e.g. "a numbered list of 5 items, each with a one-sentence explanation" or "a single paragraph under 100 words"]. If anything in my request is ambiguous, ask a clarifying question before answering.
Gemini responds best to prompts that separate four things clearly: who it should act as, what exactly you need, any context it needs to know, and how you want the answer formatted. This one template adapts to research, writing, coding, or planning tasks just by changing what’s inside the brackets.
What this produces
A response shaped by the role, task, and format you specify — rather than Gemini guessing at tone, depth, or structure from a bare question.
Variations
Two ready-to-copy versions for the most common starting points.
Act as a research assistant with a habit of citing sources and flagging uncertainty. Answer this question with current, accurate information: [your question, stated specifically]. For each claim, note your confidence level and, where possible, the type of source it likely comes from (official documentation, news reporting, general consensus). Explicitly flag anything that might be outdated or that you’re not fully certain about, rather than presenting it with the same confidence as verified facts.
Act as a [role, e.g. “project planner with experience running small team launches”]. Break down [task or goal, described specifically] into a numbered list of concrete, sequential steps. For each step, include: what needs to happen, roughly how long it should take, and a one-sentence note on why that step matters or what commonly goes wrong there. Flag any steps that depend on external factors outside direct control.

FAQ
Does this work for image generation too?
This template is built for text-based tasks — research, writing, planning, coding. For image generation specifically, use the dedicated Best Gemini Prompts for Images template instead.
Do I need to restate the role in every follow-up message?
No — Gemini generally keeps the role and context from earlier in the conversation. Restate it only if you’re switching to a different type of task.
What if Gemini’s response is too long or too short?
State a length explicitly next time (“in 3 sentences” or “in detail, covering X and Y”) — Gemini follows explicit length instructions much more reliably than vague ones like “briefly.”
