🍼 First: 6 words grown-ups use

The tiny dictionary

Learn these 6 things and every card below will make sense.

πŸ›οΈ GitHubA giant free library where programmers share their recipes (code). Anyone can walk in and take a copy. Free.
πŸ“– RepoOne recipe book in that library. "Trending repos" = the recipe books everyone is grabbing this week.
⭐ StarsBookmarks. When 50,000 people star a repo, it means 50,000 programmers said "this is really good." It's the like button.
πŸ”“ Open sourceThe recipe is public. You can read it, use it, change it, and even sell cakes you bake with it. Nobody charges you for the recipe.
πŸ€– AgentA robot helper with an AI brain. It can read pages, think, type, and click β€” like a tireless intern who works for electricity.
πŸ”‘ API keyA name-tag that lets your robot talk to a service. Many services give free name-tags with a daily allowance β€” like free samples at Costco.
πŸ€” "Wait… why is all of this free?"
Programmers share code to become famous, get jobs, and build communities. The companies behind some tools make money selling fancy versions to big businesses β€” but the toy itself is free for people like you. Your only real "costs": your laptop, electricity, and sometimes a free-tier account. That's it. πŸ’š

  4. Out comes a finished video file. Post it.

πŸ‘€

⭐ 48,246 · biggest gainer this monthFREE · zero API fees
github.com/Panniantong/Agent-Reach

βš™οΈ How it works
  1. Install the little command-line tool.
  2. Your AI assistant can now search & read Twitter/X, Reddit, YouTube, GitHub, XiaoHongShu.
  3. Ask: "What products are trending in my niche this week?"
  4. It reads hundreds of posts and reports back.
πŸ’Έ Is it free for me?Yes β€” its whole selling point is "zero API fees." It reads public pages cleverly instead of paying Twitter's $100/mo API.

⭐ 48,208100% FREE
github.com/mvanhorn/last30days-skill

The Clicking Robot β€” lists your items everywhere

πŸ€–

page-agent (by Alibaba)

⭐ 20,918100% FREE
github.com/alibaba/page-agent

βš™οΈ How it works
  1. It's a small JavaScript brain you add to a webpage/browser.
  2. It looks at the page like a human: finds buttons, boxes, menus.
  3. You give plain-English commands: "set price to $19, category: accessories."
  4. It fills everything; you review and click Publish yourself.
πŸ’Έ Is it free for me?Free code. Needs a small AI brain for understanding pages β†’ point it at free models (Toy Chest #6). ⚠️ Marketplaces frown on full auto-posting β€” keep a human finger on the final button.
πŸ€‘ How it makes YOU moneyTwice. 1) Crosslist one item to Vinted + Depop + Facebook in one go β€” at 20 listings/day this saves hours daily. 2) Other resellers PAY $29–149/month for tools like Vendoo that do exactly this. Build yours, then sell access. Proven market.

Skill Packs β€” the new thing people are selling

A "skill" is just a lesson card for AI robots. Right now, packs of lesson cards are getting tens of thousands of stars a month. You can install them free β€” and more importantly, make your own and sell it.

Your Own Store β€” stop paying the mall

🧱

Instatic

⭐ 1,961 · +518 todayFREE
github.com/CoreBunch/Instatic
Like you're 5: Depop and Vinted are malls β€” they take a cut of every sale (Depop β‰ˆ10% + payment fees). Instatic is a free kit that builds you your OWN little shop-website in about 1 minute, where you keep 100%.

β›½ Toy Chest #6

Free AI Fuel β€” the trick that makes everything above $0

Most robots above need an "AI brain" to think. Brains usually cost money per use. These two tools collect all the free samples from AI companies into one big free tank.

πŸ›’οΈ

freellmapi

⭐ 14,540~1.7 BILLION free tokens/mo
github.com/tashfeenahmed/freellmapi

βš™οΈ How it works
  1. Sign up for free accounts at AI providers (it lists which).
  2. Put the free keys into freellmapi β€” it becomes ONE address.
  3. Point any tool above at that address.
  4. It auto-switches providers when one runs out ("failover").
πŸ’Έ Is it free for me?That's its entire purpose. Free tool stacking free tiers = your listing descriptions, video scripts, and trend summaries cost $0.

The Photo Robot β€” eyes for quality control

πŸ‘οΈ

supervision (by Roboflow)

⭐ 46,150FREE
github.com/roboflow/supervision
Like you're 5: A robot eyeball for Python. It can look at a photo and go "there's the product, there's the detail" β€” then crop it, cut the background out, or count things, for hundreds of photos while you sleep.
βš™οΈ How it works
  1. A free Python library β€” a few lines of code (I can write them for you).
  2. Feed it a folder of your raw phone photos.
  3. It auto-detects the product, crops to 3:4, cleans backgrounds.
  4. Bonus: compare original vs AI-enhanced photo to catch "drift" (wrong stone count!) automatically.
πŸ’Έ Is it free for me?Yes, fully free library, runs on your laptop.
πŸ€‘ How it makes YOU moneyAt 20 listings/day, photo prep is your bottleneck. Auto-crop + auto-QC turns an hour of fiddling into minutes β€” and catches the AI-drift fails before a buyer does.
