Building is easy now. Marketing isn't. Here are the AI tools that helped with each marketing task

I built my app in months. Marketing has been the hard part. There's no "vibe marketing" yet, but a few tools made specific jobs much easier. Here's what I used, task by task:

1. Launch video → ElevenLabs

• What I used: its image, video, voice, and music tools. I made one reference image of my character and generated every scene from it, so his face stayed the same. The voices use Eleven v3 dialogue with tags like [tired] and [pause].

• Tip: avoid the AI agent editor. It used about 3x the credits I expected. Generating each piece yourself is cheaper.

2. Editing, captions and motion graphics → Claude

• What I used it for: text animations, chat-bubble scenes, captions, and syncing the voices to each scene.

• Tip: ask for the animations as code (HTML) and have it rendered to video. It's pixel-perfect and costs no video credits.

3. Social copy → Claude

• What I used it for: one idea rewritten for each platform (Peerlist, X, Instagram, YouTube), each within the platform's length limits.

• Tip: give it your real story and your real numbers. Generic prompts get generic posts.

4. Brand assets → Claude + my existing design tokens

• What I used it for: a logo lockup, a YouTube banner that fits YouTube's safe area, and a shareable results card.

• Tip: paste your exact brand colors and font so everything stays consistent.

5. Built-in distribution → a shareable results card in the product

• Users share their result, and the card links back to the app. It's the one channel that grows without me posting.

What still doesn't have a tool: taste, consistency, and showing up every day.
