How to Build and Sell AI Video Scripts Using Synthesia That Remove Filler Words and Charge Clients $500 to $1200 per Project

We built a Synthesia video script service from scratch and tested it with real scripts. The result: clean, filler-free videos that look like a production team made them. This guide covers how to write scripts that remove filler words, how to produce the final video in Synthesia, and how to price and sell this as a $500 to $1,200 service.

Imagine sending a client a polished AI avatar video instead of a shaky Loom recording. No "um," no "uh," no dead air. Just a clean, confident message that makes your client look like they have a media team. That is what this service delivers.

What Is a Synthesia Filler Word Removal Video Service and Why Does It Matter?

A Synthesia filler word removal video service is a done-for-you offering. You take a client's raw talking points or rough transcript, clean the script using AI, and produce a polished video using a Synthesia AI avatar. The client gets a professional video without ever appearing on camera.

Who buys this: coaches, consultants, real estate agents, course creators, and small business owners who need video content but hate how they sound on camera. The market is large. According to Wyzowl's 2024 Video Marketing Report, 91 percent of businesses use video as a marketing tool, but most struggle with production quality.

What you charge: $500 for a single video package, up to $1,200 for a multi-video bundle with script revisions. We cover exact pricing below.

Which Tools Should You Use?

You need three tools: one for script cleaning, one for video production, and one for delivery.

We use Claude for script work. It handles long transcripts without losing context, which matters when a client sends you a 2,000-word rough draft. ChatGPT and Gemini work too, but Claude stays consistent across longer documents.

For video production, Synthesia is the clear choice here. It has 160-plus avatars, supports 120 languages, and produces broadcast-quality output.

Your tool cost is roughly $49 to $73 per month. On a $500 project, your margin is strong.

How to Get Started Step by Step

• Collect the raw content. Ask the client for a rough script, bullet points, or a recorded voice memo. A Google Form works well for intake.
• Paste into Claude. Use this prompt: "Clean this script for a professional AI avatar video. Remove all filler words like um, uh, you know, and like. Tighten every sentence. Keep the speaker's voice. Output a clean script under 300 words."
• Review and revise. Read the output aloud. Cut anything that sounds stiff. The script should sound natural, not robotic.
• Log into Synthesia. Go to app.synthesia.io, click "Create Video," choose an avatar that matches the client's brand tone, and paste the cleaned script.
• Select voice and language. Match the avatar's voice to the client's audience. Synthesia lets you preview before rendering.
• Export and deliver. Download the MP4. Send it via Google Drive or a client portal. Include one round of revisions in your base price.

A single project takes 90 minutes or less once you have the workflow dialed in. If you want to automate the proposal side of this service, How to Build a Proposal Automation System Using PandaDoc and AI That Cuts Your Proposal Writing Time From 2 Hours to 15 Minutes shows you exactly how.

What to Watch Out For

Synthesia avatars do not handle emotional nuance well. If a client's script needs warmth or humor, the avatar can come across as flat. Set expectations upfront. Tell clients this works best for informational, sales, or explainer content, not heartfelt personal messages.

Also, Synthesia's Starter plan limits you to 10 minutes of video per month. If you land multiple clients fast, you will need the Creator plan at $89/month. Factor that into your pricing before you scale.

One more thing: some clients will send you a 1,500-word script and expect a 3-minute video. That does not work. A 3-minute video needs roughly 450 words. Coach clients on this early or you will spend extra time cutting their content down.

What to Do Right Now

Open Claude today and paste in a rough script you already have, even your own bio. Run the filler word removal prompt from step 2 above. Then sign up for a Synthesia free trial and produce one test video. That is your proof of concept and your portfolio piece.
