How to Create a GRWM Video with AI (2026 Tested Method)

Before recording, create a script. The fastest way to do this is with a large language model.

Using a tool like ChatGPT-4o or Claude 3 Sonnet, you can generate a complete video outline in under 60 seconds. Provide a detailed prompt specifying the event, the style, and the products you'll feature.

For example: "Write a 45-second GRWM video script for a casual coffee date. Include 5 steps: skincare prep, foundation, simple eye makeup, blush, and choosing a knit sweater.

Make the tone chatty and mention a specific product like 'Saie Glowy Super Gel'." The AI will output a structured script with timings and talking points. This prevents rambling and ensures your final video is concise and engaging, which is critical for retaining viewers on platforms like TikTok where the average watch time is just seconds.

High-quality audio is essential for a polished GRWM video. You have two primary options: record your own voiceover or use an AI voice generator.

For an authentic feel, recording your own audio with a simple USB microphone provides a personal touch. However, for speed and consistency, AI voice tools are highly effective.

Services like ElevenLabs or PlayHT can convert your script to speech that is nearly indistinguishable from a human voice. The free tier on ElevenLabs, as of Q1 2026, includes 10,000 characters per month, enough for about ten short videos.

The key is to select a voice that matches your brand's personality—whether it's energetic or calm. A common mistake is using a generic, robotic voice, which can immediately signal low-quality production to viewers.

With your audio complete, gather your video clips. For a GRWM, this involves filming short segments (2-4 seconds each) of your routine.

Ensure all footage is shot in a 9:16 vertical aspect ratio for Reels and TikTok. The most important step is the edit.

Import your AI voiceover track into a video editor first, then lay your video clips on the timeline to match the narration. This audio-first approach is 3x faster than trying to narrate over a pre-edited video.

Make quick cuts that align with key phrases in the script. For example, when the voiceover says "applying foundation," the corresponding clip should appear instantly.

This synchronization keeps the viewer engaged and makes the video feel professionally produced.

The final assembly is where an AI video tool accelerates the workflow. Instead of manually aligning every element, you can use a platform that automates the process.

An AI-powered editor like FluxNote can take your script, audio file, and video clips and help synchronize them on a timeline. The main time-saver is the auto-captioning feature.

Since studies show up to 85% of social videos are viewed without sound, captions are not optional. Generating them automatically saves at least 15-20 minutes of tedious work per video.

You can then adjust the caption style and timing to ensure they are perfectly synced and easy to read, a critical step before exporting your final 1080p video file.

Before publishing, perform a final optimization pass for each platform. While the core video is the same, details matter.

For Instagram Reels, add a trending audio track from the Instagram library and set its volume to 1-5% behind your main voiceover. This can significantly boost reach.

For TikTok, use the platform's native text overlay for a key hook in the first 3 seconds, even if you already have captions. Research 3-5 relevant hashtags using a tool like Flick or by checking top-performing videos under the #grwm tag.

A common oversight is forgetting a cover photo; design a simple one in a tool like Canva with a clear, bold title that tells the viewer exactly what the video is about before they click play.
