## 14DaysOfAI (100 School)

14DaysOfAI (now also presented as "15 Days of AI") is an email-based learning challenge run by 100 School. Instead of long video courses, it sends one compact lesson to your inbox every weekday morning, sized for roughly 15 minutes of focused practice. The curriculum is split into three arcs: thinking with AI, building with AI, and working with AI, so learners move from first principles to hands-on automation and prototyping.

The challenge is aimed at professionals rather than developers. Lessons mix explanation with concrete tasks, so you finish with working prompts, small workflows and an automation habit instead of just theory. 100 School also offers a teams track for organisations that want structured AI upskilling with accountability, and runs a newsletter plus additional courses on no-code and writing.

Because it is delivered by email, the format adapts well to busy schedules: there is no fixed class time, and you keep the lesson archive to revisit later. It is free to join the individual challenge.

**Pricing & Plans:** The individual challenge is free to join. 100 School sells a separate paid offering for teams; specific pricing is quoted on request.

- **Daily email lessons:** A new lesson lands in your inbox each weekday morning, designed to be completed in about 15 minutes.
- **Three-week skill arc:** Progresses from how AI models work, to building prompts and automations, to embedding AI into your daily workflow.
- **Task-based practice:** Lessons pair each concept with a real work task so you produce usable outputs, not just notes.
- **No setup required:** Everything runs through your existing email and whatever AI tools you already use; no installs or coding environment.
- **Teams programme:** A structured version for organisations that adds accountability and group capability building.

**Strengths:** Very low time commitment, roughly 15 minutes per weekday; Free to join the individual challenge; Practical, task-oriented curriculum rather than passive video; Delivered by email, so it fits any schedule and works on any device

**Limitations:** The daily drip format means you cannot binge the whole curriculum at once; Best results depend on actually doing the tasks, which takes discipline; Content is generalist, so specialists may want deeper technical material

## 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
