Reels scripts in AI: how to cut the long intro and get to the point

I work in SMM and create three or four Reels scripts every day, come up with five opening lines, re-edit two videos after client feedback, and somehow end up arguing about whether that emoji is really needed in the third frame.

That’s why I stopped looking for just any AI that writes viral scripts. I haven’t found that magic button yet. But I did find something more useful: setting up an AI agent that understands the mechanics of short videos and then receives specific details about the niche, product, audience, and task each time.

This is especially important for me because I work with different projects. Today it’s cosmetics, tomorrow a restaurant, the next day an expert blog, and a week later a travel account. A single universal template quickly starts sounding repetitive, with only the brand names changing.

Why standard AI for scripts quickly starts writing the same thing

You can open any AI assistant and type: “Come up with a viral Reels script for a coffee shop.”

The response will likely be decent. Then you ask for five more options. They will also be decent.

And then the familiar cycle begins:

• “Can you make it livelier?”

• “Make the opening catchy.”

• “Now without clichés.”

• “Now make sure people watch until the end.”

• “Now make it less salesy.”

And instead of a script, you end up with a small literary club. The problem often isn’t the AI itself. It doesn’t know which specific mechanics you want. If you simply ask it to write a viral video, it starts guessing.

I find it more efficient to explain the agent’s operating rules upfront, then provide specific tasks in subsequent requests.

Masha GPT This platform is particularly useful as an AI aggregator: it brings together various models in one service and offers a dedicated agent mode. The platform currently provides access to dozens of models and tools, including text, image, and video generators. This means I can use Masha GPT not just as a chatbot for drafting text, but as a workspace where scriptwriting is only the first step.

How to set up an AI agent for Reels scripts

First, I define the agent’s workflow rather than the topic of a specific video. Here is the prompt for Reels scripts that you can use:

You are a professional screenwriter for short vertical videos on Reels, Shorts, TikTok, and similar formats. Your task is to create scripts that hold attention, convey the main idea quickly, and align with the mechanics of the specific niche.

Before writing a script, analyze the specified niche, product, audience, account format, and video goal. Do not use a single universal structure for all tasks.

Identify which attention-holding mechanics are natural for this niche: curiosity, relatability, conflict, contrast, unexpected observations, mistakes, myth-busting, result demonstrations, personal stories, humor, practical value, social proof, intrigue, questions, open loops, or other suitable techniques.

Do not promise virality or make false claims. The goal is not to guarantee views, but to increase the likelihood of retaining attention through strong structure, clear ideas, and relevance to the audience’s interests.

For each request, first determine:

1. who the viewer is;

2. why the topic might interest them;

3. what conflict, question, or interest arises in the first few seconds;

4. the key message the viewer should take away;

5. what will keep them watching until the end;

6. the logical next action after viewing.

Do not start the script with long introductions, greetings, author bios, or obvious topic descriptions. If the context allows, start immediately with action, results, conflict, an unexpected thought, a question, or a specific situation.

Write in natural, conversational language. Avoid advertising clichés, excessive emotion, and phrases like “you won’t believe,” “shocking,” or “this will change your life,” unless such clickbait styles fit the specific project.

Consider the visual component of the video: suggest what should happen on screen alongside the dialogue if it helps maintain attention.

For short videos, always account for the actual speaking duration. Avoid overloading the script with text.

If I specify a video length, calculate the speech volume accordingly. If no length is specified, aim for a short, dynamic clip and indicate the approximate voiceover time separately.

Unless I request otherwise, always offer two ways to present the same idea:
Option A — more direct, fast-paced, and practical.
Option B — more emotional, narrative-driven, or provocative, if suitable for the niche.

Do not change the core message between options. Change only the delivery style.

Output format:
1. Mechanism: which retention mechanism is chosen and why it fits this niche.
2. Hook: the opening phrase or action.
3. Script: lines plus brief visual cues.
4. Closing: final thought and a natural call to action.
5. Duration: approximate speaking time.
6. Improvement tips: one or two recommendations for filming or editing.

If information is insufficient, ask only essential questions. Do not invent facts about the brand, product, expert, or personal experience.

Your main goal is not just to write polished text, but to create a script ready for short-form video production.

This is where a well-configured AI agent shines. I once explained how it should approach script thinking, not just writing. This doesn’t mean the neural network literally thinks like a human. Rather, we predefine the analysis sequence it must follow for the task.

Start with a 30-second structure

Suppose I need to adapt an expert topic into a short video. I give the agent this prompt:

Adapt an expert topic into a Reels script of about 30 seconds.

Topic: [INSERT TOPIC].

Target audience: [DESCRIBE AUDIENCE].

Product/expert: [NAME].

Video goal: [REACH / SUBSCRIPTIONS / SALES / TRUST / CLICK-THROUGH].

Build the script using this structure:
hook → core idea → demonstration → closing.

Open with an immediate reason to keep watching. Skip greetings and long introductions.

In the main part, explain one key idea. Don’t try to squeeze five tips into 30 seconds.

In the demonstration, show a concrete example, action, result, or situation.

End with a natural transition to the call to action.

Provide two delivery options for the same topic:

1. direct and practical;

2. emotional or story-driven.

Avoid false promises, unverified numbers, and phrases like “this is guaranteed to go viral.”

After the scripts, indicate the approximate speaking time.

In fact, after the first prompt, the agent itself asked similar questions to help me define the specific Reels topic:

It’s no longer just “write me a Reel,” but a proper technical brief. This significantly improves the result. I asked for a script for a cosmetic clinic, specifically promoting biorevitalization treatments for women aged 35–45. Note: if you need to base the script on expert knowledge, upload a report, scientific article, or text from your specialist. This allows the agent to extract facts, figures, and phrasing without making things up. I uploaded a link to an expert article: 

Here is the Reel script I received from the very first generation: 

Option A: Direct and Practical (Expert Logic)

1. Retention mechanism: Contrast and addressing a hidden objection (the myth that any injections change facial features). 2. Hook: “After 35, even a $300 cream stops delivering that fresh look. And it’s not about the cream.”

• Speech duration: ~27–29 seconds (68 words at a calm, confident pace).

• Shooting tips: Use clean, diffused lighting without aggressive beauty filters. For a premium audience, the honest texture of well-cared-for skin is essential.

Option B: Emotional and situational (Life trigger)

1. Retention mechanic: Relatability through a common work scenario (looking tired on video calls despite having inner energy). 2. Hook: “You’re well-rested and full of energy, but in the mirror and on calls, you look like someone who hasn’t slept in a week.”

• Speech duration: ~26–28 seconds (64 words at a lively conversational pace).

• What to improve during filming: The expert’s attire should be understated monochrome (white, graphite, beige), creating a premium minimalist look without distracting visual noise to emphasize the clinic’s high status.

How to check if your script really fits into 30 seconds

There is one thing I always recommend: read the script aloud. Not silently in your head, but out loud. Because saying “this should take about 30 seconds” and actually speaking it are two different realities.

If I’m reading the text and at the 24-second mark realize I still have half the script left, then it’s not a 30-second script. It’s a 47-second script that desperately wanted to be 30 seconds.

Here’s what I usually do:

1. Paste the finished script into notes;

2. Start a timer;

3. Read at a normal conversational pace;

4. Note where I have to speed up;

5. Remove anything that doesn’t advance the story or idea.

Pay special attention to the first 5 seconds. If there are three introductory sentences there, the video is already asking too much of the viewer.

Three ready-made prompts for different niches

The same AI assistant can work very differently depending on the task. I wouldn’t create a separate agent for every niche. It’s easier to keep the core setup and change the input data. Here are three examples for three different niches.

I recommend saving these templates separately. When working with four clients simultaneously, searching your mind for the perfect prompt formulation is a luxury you can’t afford.

Where you can write a script and immediately proceed to creating visuals

For me, the most convenient format here is one where scriptwriting and content production aren’t scattered across five different services. In Masha GPT , text models, image and video generation, and additional tools are available. The service allows switching between models within a single workspace; the website also highlights an AI agent mode.

Therefore, the workflow looks something like this:

idea → AI agent → script → timing check → footage → cover → final video.

For example, an AI agent wrote a script about a coffee shop. I realize that some scenes can be created using AI. Instead of going off to find a separate image generator, I can switch to the visual part within the same workspace. If I only need a script, I stay in text mode. If I need images, I generate them next. If I need a cover, I formulate a separate request for the visual.

This is exactly the case where an AI aggregator is useful not for the number of models in a pretty table, but for reducing the steps between an idea and ready-made content.

What I changed in my work after setting up the agent

I used to start with the question: "What should I write in the first three seconds?" Now I start with a different one: "Why should a person stay after the first second?"

The difference seems small only in words. If you first define the viewer's interest, conflict, promise of specific benefit, or intrigue, the script becomes much easier to assemble. Then you can choose the format: dialogue, UGC, expert monologue, sketch, demonstration, or storytelling.

That is why I would not advise looking for one "best neural network for scripts." It is better to configure an AI agent for the very principle of working with scripts, and then give it different tasks.

• Today — cosmetics.

• Tomorrow — a coffee shop.

• The day after — travel.

And in a week, the client will suddenly ask for a Reel about industrial equipment. This is where the versatility of the setup is tested: a good agent should not drag beauty blogger mechanics into B2B, but first figure out what actually makes people watch short videos in this particular niche.

Save this algorithm

In short, my current workflow is as follows:

1. Set up the agent — explain the principles of creating short videos to it.

2. Provide context — niche, product, audience, goal, platform.

3. Request two options — direct and emotional/story-driven.

4. Remove the introduction — if it can be cut without losing meaning, cut it.

5. Check the speech with a stopwatch — always out loud.

6. Check the first few seconds — the viewer must understand why they should keep watching.

7. Move to production—footage, images, video, and cover art.

Only then ask yourself: “Will this go viral?” Because no prompt, AI tool, or even a social media manager with 15 years of experience can honestly guarantee virality. What you can do is trim unnecessary parts from the script, strengthen the opening line, make the structure clear, and give your video a better chance of being watched.

And that’s a concrete task you can tackle every day.

If you regularly write scripts for Reels, save this guide in full. Pay special attention to the core prompt for the agent. Setting up a solid workflow once is far more useful than starting a new chat every day with “come up with something viral.”
