1. Research: Perplexity
Stop guessing what to make. Find out what people are already searching for.
The prompt:
```
What are the most common questions people ask about [TOPIC]?
What existing videos on this topic are missing?
Give me 5 video ideas with specific angles.
```
Perplexity cites its sources. You can click through to verify. This replaces two hours of manually browsing YouTube search results and reading Reddit threads.
Free tier: 5 Pro searches/day. Use them for topic research. Regular unlimited search for follow-up questions.
---
2. Scripting: Claude
ChatGPT can write a script. Claude writes one that sounds like you talking, not a robot reading a Wikipedia article.
The prompt:
```
Write a YouTube script about [TOPIC].
Tone: conversational, like you're explaining to a friend.
Structure:
- Hook (5 seconds): surprising fact or question
- Body: 3 main points with examples
- Outro: one clear takeaway + call to action
Rules: under 1,500 words. No jargon. No "in today's video."
Read at an 8th grade level.
```
Why Claude over ChatGPT: Claude's prose sounds more human. For a script you'll be reading out loud, natural phrasing matters more than perfect grammar.
Free tier: ~20-30 messages/day. Enough for 5-7 script drafts daily.
---
3. Thumbnails: ChatGPT (GPT Image)
Thumbnails get the click. GPT Image generates them from a prompt.
The prompt:
```
YouTube thumbnail for a video titled "[TITLE]".
Bold, high contrast, warm colors. Face with surprised
expression (not real person, illustrated). Clean
composition. 16:9 aspect ratio. No text on the image.
```
If you need text on the thumbnail, switch to Ideogram (free tier) for better text rendering. ChatGPT is better at the images. Ideogram is better at putting words on them.
---
4. B-roll: Pexels + Pixabay
AI-generated video is not ready for prime time yet. Stock footage is.
Workflow:
- Read your script. Highlight every noun and action verb.
- Search each on Pexels and Pixabay
- Download 2-3 clips per keyword
- You'll use maybe half. That's fine. Options > no options.
Both sites are free. No attribution required. Search by keyword, download the highest resolution available.
---
5. Music: Suno
Background music sets the tone. Suno generates original tracks so you never worry about copyright strikes.
The prompt:
```
Upbeat lo-fi instrumental, 90 BPM, background music for a
tech explainer video. No vocals. Warm, positive energy.
```
Download the track. Import into CapCut. Set volume to 15-20% so it doesn't compete with your voice.
Free tier: 5 generations/day. Save the good ones. After a week you'll have a library of 10-15 original tracks you can reuse.
---
6. Voiceover: ElevenLabs
Don't want to record your own voice? ElevenLabs generates natural-sounding narration.
The workflow:
- Paste your Claude-written script
- Pick a voice (dozens available, sorted by style)
- Adjust speed to 0.9x (slightly slower sounds more natural)
- Generate
- Download as MP3
Free tier: 10 minutes of generated audio per month. One 8-10 minute video uses most of it. For multiple videos per month, upgrade to Starter ($5/month).
---
7. Editing: CapCut
CapCut is free. No watermark. Made by the TikTok company. Optimized for vertical video, works for horizontal too.
The 10-minute edit workflow:
- Import audio (your ElevenLabs file or your own recording)
- Drag B-roll onto the timeline
- Align clip changes with sentence breaks in the audio
- Add background music at 15-20% volume
- Add auto-captions
- Export
No color grading. No fancy transitions. No effects. Good content does not need them.
---
8. Captions: CapCut Auto-Captions
CapCut transcribes your audio with ~95% accuracy. The remaining 5% are proper nouns and technical terms.
The 2-minute caption fix:
- Click Text → Auto Captions
- Let it process
- Scroll through. Fix the 5% that are wrong.
- Choose a caption style (clean sans-serif, no animations)
Captioned videos get higher watch time. Many people watch with sound off.
---
9. YouTube SEO: TubeBuddy
TubeBuddy is a browser extension that tells you how to title and tag your videos.
Free tier features:
- Tag suggestions based on what top-ranking videos use
- Search volume estimates for keywords
- Competitor tag analysis
The free tier is limited but useful. For serious YouTube SEO, VidIQ's free tier is the alternative.
---
10. Publishing: Buffer
Record once. Publish everywhere. Buffer schedules posts across platforms.
Free tier: 3 social channels. Connect YouTube, Twitter/X, and LinkedIn. Write one post, schedule it everywhere.
The 30-second cross-post:
- Upload video to YouTube
- Copy the description
- Paste into Buffer → post to Twitter + LinkedIn
- Schedule for optimal posting time

FAQ
Q: Do I need all 10 tools?
A: No. Start with Claude (scripting), CapCut (editing + captions), and Pexels (B-roll). Those three cover 80% of the time savings. Add the others as you need them.
Q: Will my audience know I used AI?
A: Not if you edit. AI scripts need a human pass. AI thumbnails need a human check. AI captions need human corrections. The tools accelerate. The human makes it good.
