Every week our Radar goes through GitHub looking for small projects that are picking up speed before everyone else notices them. This week it brought back four hidden AI tools on GitHub, and none of them has reached 2,000 stars yet.
Everything below is what each project's README says, so read it as a heads-up, not a review. We spotted them; you get to try them and tell us how it goes.
1. Mika: can an AI use your Android apps while you keep using your phone?
See it on GitHub
★ 1,755 stars as of 31 Oct 2026, for a repository created two days earlier.
Its README describes an Android app that takes a one-sentence request and carries it out on your phone. It drives your apps on a hidden background screen, so you can keep scrolling while it works.
Why it caught our attention: most phone apps have no API. Mika looks at the screen and taps the way a person would.
Honest caution: it's a public beta, it needs your own model API key or a ChatGPT login, and its authors ask you to read their disclaimer first (automating other apps may break their terms).
2. whatsapp-mcp: what did I miss in that WhatsApp group?
See it on GitHub
★ 397 stars as of 31 Oct 2026, plus 157 points on its Show HN post.
Its README says you link your phone once, the way you'd link WhatsApp Web, and from then on Claude, ChatGPT or Grok can search and read your chats. It's read-only, so it can't send anything. One example prompt: "Summarize what I missed in the family group this week". Anyone with family in another time zone will feel that one.
Why it caught our eye: we already run a similar read-only WhatsApp setup for our own morning catch-up, and it's the kind of workflow that saves real time. One honest difference: this repo keeps your messages in Cloudflare (its README says your own copy needs the Workers Paid plan), while a local version leaves them on your own computer. Worth thinking about if you have client chats in there.
Honest caution: the README itself warns that WhatsApp's terms discourage this kind of linked device and the account could be restricted.
3. unslop: how do you make an AI-made website look designed?
See it on GitHub
★ 1,568 stars as of 31 Oct 2026, also two days old.
Its README describes a Claude skill that finds the slop first (purple gradients, glows, emoji labels, shouty copy) and fixes the screen pass by pass, like a designer would. It can also make a short before-and-after video of your screen "unslopping itself", ready to post.
Why it's interesting: you know the look. Finally someone named it.
Honest caution: the video needs Playwright and ffmpeg installed.
4. Kensaku: can you search your screenshots by the words inside them?
See it on GitHub
★ 314 stars as of 31 Oct 2026.
Its README describes a free, open-source launcher for Windows, macOS and Linux that finds PDFs by topic and screenshots by the text inside them. It says nothing leaves your machine, and your AI can search the same index over MCP, read-only.
Why it caught our attention: the README calls it "screenshot archaeology". I felt seen.
Honest caution: builds aren't code-signed yet, so expect a warning the first time you open it.
What these four have in common
Three of the four open doors that are normally shut: phone apps, WhatsApp, your screenshots. That's the exciting part, and why each one comes with a caution line.
The real question
Which of these would you actually let near your phone or your chats? Try one and tell us how it goes on WhatsApp.
Rather set up your AI tools with someone next to you? Here's how we start.
