Prompts for Meta AI: Research, Writing, and Planning

Meta AI is available across Meta's apps — WhatsApp, Instagram, Facebook, and at meta.ai — making it a convenient assistant for quick research, drafting, and planning without switching to a separate app. The most effective prompts for any of those surfaces share the same principle: give the model the context it needs before making a request.

Like any AI assistant, Meta AI can state things confidently that are incomplete or wrong. The prompts below include verification steps for factual claims. Tools like fenbs keep reusable prompt versions and your confirmed findings so they carry across sessions and to other AI apps when you need more capability.

How Meta AI differs from other assistants for prompt purposes

Meta AI does not currently support a persistent system prompt the way ChatGPT's custom instructions do. Each conversation starts without memory of previous ones by default. That means useful context — your role, your project background, your preferred response style — needs to appear in the conversation itself rather than in a standing setting.

This makes the first message in any session important. A session that opens with your context produces more relevant responses from the first reply onward. A session that opens with a direct question gets a general answer that you then have to correct with follow-up context — which takes more messages to reach the same quality.

Check Meta's help pages↗ (opens in a new tab) for the current state of memory and personalization features, as these have been evolving. Where features exist, use them; where they do not, build the context into the prompt.

Prompts for quick research

Meta AI can search the web in some contexts. For any factual claim you will rely on, ask it to flag uncertainty rather than state things confidently. This is especially important for US regulatory, legal, or financial claims, where a summary can omit a qualification that changes the practical meaning.

I am researching [topic] for [purpose]. Give me a summary of the key facts. For each fact, tell me whether you are confident in it or whether I should verify it. For anything I should verify, suggest where to look.

Is the following accurate: [specific claim]? If you are confident, explain why. If you are not certain, say so and tell me where I could verify it. Do not present it as fact if you are unsure.

For US regulatory, legal, or financial claims, verify against official sources: FTC at ftc.gov, IRS at irs.gov, SEC at sec.gov, or the relevant agency. Meta AI can point you in the right direction, but the agency's own documentation carries the authoritative version.

Prompts for writing and drafting

Writing prompts need to supply the audience, purpose, and constraints that Meta AI cannot know without being told. Including these details in the first message produces a draft that is closer to usable than one that requires several rounds of correction.

Write a [type of writing, e.g. message, caption, summary] for [audience]. Purpose: [one sentence]. Key point to include: [one or two facts]. Keep it to [target length]. Tone: [formal / casual / direct].

Here is a draft: [paste draft]. Tell me: (1) is the main point clear? (2) what is the weakest sentence, and why? (3) what would you change to make it more effective for [audience]? Be direct.

When Meta AI revises a draft, compare the revision to the original. A model given a draft to improve will sometimes smooth out the voice along with the problems — particularly in conversational writing where a slightly unpolished phrase was intentional.

Prompts for planning and decisions

Planning prompts work best when the model is given the specific constraints of your situation rather than asked for generic advice. Generic advice is typically the kind of thing you have already read; specific advice addresses your actual constraints and what you have already tried.

I need to [goal] by [timeframe]. My constraints are: [list]. What I have already done: [list]. Give me the next three steps, in order of importance. For each step, note any risk or dependency I should know about.

I am deciding between [option A] and [option B]. My priorities are: [list, in order]. My constraints are: [list]. Analyze each option against my priorities. Do not make the decision for me — give me the analysis and flag what I am missing.

Building context into the prompt

Since Meta AI does not currently persist preferences between sessions, supply role context at the start of conversations where it matters. A short context block at the top of any message does the job. Keep it to three or four lines — enough to anchor the model without taking so long to write that it defeats the purpose of using a quick assistant.

My context: I am a [role] working on [project type]. My audience is [description]. My preferred style is [brief description]. With that in mind: [your actual request].

If you use the same context block for every session on a project, save it somewhere you can paste it quickly. Keeping a library of context blocks — one per client, project, or role — means each conversation starts from a known baseline rather than from a general-purpose default.

Keeping reusable prompts across sessions and apps

Meta AI's session-level memory limitation means reusable prompts need to live outside the app. For most purposes, a notes app or snippet manager is enough. If you use multiple AI apps and want the same prompt context available across all of them, a shared skills store removes the need to maintain separate copies in different places.

How to do this with fenbs

1. Create a free account and set up a project for your work or study.
2. In Skills and prompts, save your most useful prompt templates: context block, research prompt, writing prompt, planning prompt.
3. For each project, add context notes with the background you paste into Meta AI at the start of relevant sessions.
4. Connect a supported AI app from Integrations for tasks that benefit from a direct MCP connection. Use Meta AI alongside it for quick drafts and messages.
5. After sessions where you confirm important facts or decisions, record them in fenbs so they carry into the next session in any app.

fenbs does not connect to Meta AI directly. It is most useful here as a prompt library and record-keeping tool for projects that span multiple sessions or tools. If your work stays in short, contained Meta AI conversations, the prompts above work without any additional tool.
