Rather than a long video course, it is delivered as a sequence of short daily emails: you receive a lesson on a weekday morning, apply it to a real task that day, and return the next morning for the next building block. The structure is designed to break the loop of endless tutorials by forcing small amounts of deliberate practice. The curriculum moves through three broad arcs. It starts with how AI systems actually work and how to spot useful opportunities in your own role, then progresses to building: drafting, analysing, automating and prototyping with AI as a co-pilot, and finally to making AI a durable part of your daily rhythm through repeatable systems and habits. The goal is not tool trivia but judgement — the ability to pick up any AI product and use it competently. The challenge is oriented toward individuals but is also packaged for organisations that need to raise AI literacy across a whole team, with a sales-led track for company-wide rollouts. Because lessons are emailed, no software install or special account is required beyond signing up with a work email address. **Pricing & Plans:** The email challenge is free to join for individuals — you sign up with your name, company website and email. Team and enterprise rollouts are quoted separately through a sales conversation; specific team pricing is not published on the site. - **Daily emailed lessons:** A new short lesson lands in your inbox every weekday morning, so progress fits around a working day instead of competing with it. - **Three-phase curriculum:** Think with AI, build with AI and work with AI: a progression from fundamentals to automation to lasting habits, rather than a random tour of tools. - **Applied real-work tasks:** Each lesson asks you to use AI on something from your actual role, so you finish with artefacts and workflows you can keep using. - **Team programs:** Structured rollouts bring the same curriculum to a whole organisation with accountability and shared momentum, arranged via a sales conversation. - **Large peer community:** You learn alongside thousands of other professionals going through the same challenge, with supporting insights and case studies from 100 School. **Strengths:** Very low time commitment: roughly fifteen minutes per day, five days a week; Email delivery means no new app to install or platform to learn; Curriculum is practice-first, with tasks tied to your own real work; Free for individual learners, with a straight path to team programs **Limitations:** The current format is 15 days rather than the original 30, so expectations should be reset; No interactive live instruction is included at the individual level; Advanced or highly technical AI topics are out of scope [Profile (Markdown)](https://openaitools.app/tool/30daysofai.md) ## PromptHero PromptHero started life as a gallery where people could look up prompts for image models and see the exact text that produced each result. That archive is still at the centre of the product, and it has grown to cover video models, language models and newer image engines. You can filter by model, style or trending categories, open any creation to inspect its prompt and parameters, and copy it into your own workflow. Over time the site has expanded into an actual creation tool. After signing in you can write a prompt, pick a model from a wide catalogue and generate images or videos on PromptHero's own infrastructure, keeping your results private or publishing them to the community. A credits system governs how much you can generate, and unused credits roll over rather than expiring. PromptHero is also a learning resource. Its Academy section, model directory and prompt collections are aimed at people who want to understand prompt engineering rather than just copy a string of text. The platform is independently operated and is not affiliated with or endorsed by Midjourney, OpenAI, Stability AI or any other model vendor it references. **Pricing & Plans:** Freemium. A free account gives limited daily generations at standard speed with public results. Starter is about $19/month and Pro about $29/month on monthly billing, both including a monthly credit allowance, private generations, all models and faster queues. One-off credit packs (roughly 1,000 credits for $59 and 2,000 for $99) never expire, and annual billing often runs a two-months-free promotion. - **Millions of searchable prompts:** Search and filter a large library of community prompts by model, style or category, and see the exact text behind each result. - **Built-in image and video generator:** Create images and videos on-site with models including ChatGPT Image, Midjourney, FLUX, Nano Banana, Seedream, Veo and Sora. - **Model directory and comparisons:** Browse documented AI image, video and language models in one catalogue to decide which engine fits your task. - **Private generations and rollover credits:** Paid plans keep your output unlisted, and unused generation credits accumulate instead of expiring each month. - **Academy and prompt guides:** Structured lessons and prompt-writing references for anyone moving from copying prompts to writing their own. **Strengths:** Very large, well-categorised prompt archive with exact prompts visible; Generation across many models in a single interface; Private generations on paid tiers and credits that never expire; Free tier is genuinely usable for testing **Limitations:** Free tier output is public and limited to a small daily quota; Credit consumption varies a lot by model and resolution; Interface is dense, with a lot of navigation for new users; Prompt quality is community-driven and inconsistent [Profile (Markdown)](https://openaitools.app/tool/prompthero.md) ## Frequently Asked Questions ### How do 30DaysOfAI (100 School AI Challenge) and PromptHero compare in monthly traffic? 30DaysOfAI (100 School AI Challenge) has 26,006 monthly visits, while PromptHero has 1,044,654.
