The £0 Tech Stack Behind My £500/Month AI Side Hustle

I run a faceless YouTube channel that generates £400–£700 per month. The entire production stack costs me under £45/month — but nearly all of it can be replicated with completely free tools.

Here's the zero-cost alternative stack I wish I'd started with.

The Stack I Actually Use vs The Free Alternative

Scripting

Paid: ChatGPT Plus (£16/month)

Free alternative: Claude Free Tier + DeepSeek

Claude's free tier gives you enough monthly usage for 8–10 scripts. DeepSeek (free, no limits) handles the heavy drafting. Use both in rotation and you'll never hit a paywall. The quality difference between ChatGPT Plus and Claude Free for script organisation is negligible.

Voiceover

Paid: ElevenLabs (£4–£18/month)

Free alternative: Microsoft Edge Read Aloud

Edge's built-in TTS has British English voices that are surprisingly natural. Record system audio with OBS (free) while Edge reads your script. Quality isn't ElevenLabs-level, but for a starting channel, viewers genuinely won't notice the difference.

Thumbnails

Paid: Canva Pro (£10/month)

Free alternative: Canva Free + Photopea

Canva's free tier covers 90% of what you need. Photopea (free, browser-based) fills the Photoshop gap for advanced edits. ChatGPT generates thumbnail concepts for free — prompt it with "Give me 5 thumbnail ideas for a YouTube video about [topic]."

Editing

Paid: CapCut Pro (optional)

Free alternative: CapCut Free + DaVinci Resolve

CapCut's free tier does auto-captions, background removal, and long-to-shorts extraction. DaVinci Resolve (completely free, no watermark) handles everything else. This combination is genuinely powerful enough for professional output.

The Full Free Stack

Total: £0/month.

When to Upgrade

Start free. Upgrade only when a tool directly limits your output or earnings:

  • Upgrade ElevenLabs when you're publishing 3+ videos/week and voice quality affects retention
  • Upgrade Canva when thumbnail A/B testing shows Pro templates outperform Free
  • Upgrade ChatGPT when script research time exceeds 2 hours per video

Upgrade with revenue, not before it.

The Real Secret

The tool stack genuinely doesn't matter much. A great script recorded on a phone mic will outperform a mediocre script voiced by ElevenLabs' best British voice. The algorithm rewards topic selection, thumbnail design, and viewer retention — not which AI voiceover service you used.

Start with free tools. Publish 20 videos. Then decide what's worth paying for.
