https://plugthis.ai/rebuilds The "I Rebuilt" series: popular paid Chrome extensions, rebuilt with PlugThis. en-us Fri, 15 May 2026 08:10:26 GMT https://plugthis.ai/rebuilds/eightify https://plugthis.ai/rebuilds/eightify Thu, 14 May 2026 00:00:00 GMT Eightify charges $20/month for YouTube video summaries. I rebuilt the core functionality as a custom Chrome extension in 12 minutes using PlugThis. Here's the full prompt and what I learned. Udaya The "follow-up prompt" pattern is the real superpower. You don't need to get the build perfect on the first prompt — you can iterate. ## Cost comparison Eightify costs $20/month. The rebuild costs: - PlugThis one-time license (you already own this) - OpenAI API usage: roughly $0.02 per summary using GPT-4 mini, or $0.10 per summary using full GPT-4 For 50 summaries per month: $1–5/month vs. $20/month. Break-even on the API costs is the first month. The bigger upside: you own the extension. If Eightify shuts down or hikes prices, you're unaffected. If you want a feature Eightify doesn't have, you add it yourself. ## Compare side-by-side Full comparison of Eightify vs. building your own: [/alternatives/eightify](/alternatives/eightify). ## Next up Up next in the series: WriteSeed (AI article writer). Same template — paid SaaS at top of category, rebuild in PlugThis, document the process. If there's a specific extension you'd like to see rebuilt, reply to me on YouTube or X. ]]>
