    1. Are prompts the biggest limitation for AI website generators?
    2. Built a tool that scores your prompt out of 100 and tells you exactly what's missing — looking for people to stress-test it
    3. I got tired of wasting tokens and starting prompts from scratch. I created prompt management tool to Test/Save/organize all my prompts. It is live and free for all.

    1. I distilled the leaked Claude Fable 5 system prompt into a clean, universal 500-token Markdown engine for ChatGPT and Gemini. No bloat.
    2. Don't click buy yet. Chatgpt will find every discount code for what you're buying, then open a browser and test them at checkout
    3. reverse image search your own face and see everywhere your photos got reposted without you knowing. takes two minutes and it's actually unsettling

    1. The cheapest prompt optimisation I found this year was deleting the navigation from context entirely
    2. Cached my agent's browser paths to save tokens, spent three days debugging wrong data instead
    3. I kept getting mediocre AI outputs until I standardised how I wrote prompts. Here’s the framework.

    1. Stop letting ChatGPT be an ai writing tool for your essays. Here's the prompt I give people instead.
    2. Stop treating your AI like a senior engineer, treat it like a genius intern
    3. The prompt I run before every stakeholder review that predicts the exact questions execs will ask (the part no AI presentation tool does for you)
