Yesterday's Top Launches: 5 Tools from May 12, 2026

Yesterday’s drop of new developer tools felt unusually practical—no blockchain wrappers, no AI wrappers for wrappers, just small utilities that get out of your way. I scrolled through the five launches that hit the feed after midnight and kept three tabs open longer than I care to admit. Below is the short version of what shipped, who it’s for, and why you might (or might not) care.

PostPolish

If English isn’t your first language, commenting on Twitter or LinkedIn can feel like walking onto a stage with your zipper down. PostPolish is a Chrome extension that lives in the right-click menu and turns “i think u r right” into “I completely agree—well put.” You can also highlight someone else’s post and let the tool suggest a reply, or take a one-liner and expand it into a short paragraph that still sounds like you.

I tested it in Portuguese first, then in my broken Spanish, and the output stayed surprisingly close to my tone—no sudden MBA jargon. The polish happens inside the same tab, so you’re not bouncing to ChatGPT and losing the thread. Downsides: it only works on social sites for now, and the free tier gives you 30 actions a month, which burns fast if you’re addicted to quote-tweeting. Still, if you’ve ever deleted a reply because the wording felt off, this pays for itself in confidence.

SafeTrip

Reddit horror stories about taxi scams in Bangkok or fake petitions in Paris are gold, but they’re scattered across fifty sub-threads you’ll never find again. SafeTrip scrapes those warnings, plus blog comments and direct submissions, and drops them on a world map. Click a city and you get a short card: “Fake monk blessing – reported 12× – near Grand Palace.”

The dataset is thin for now—Berlin had two entries, Mexico City zero—but the idea scales fast if travelers actually feed it. I like that there’s no account wall; you land, search, leave. Long-term, the team wants to auto-pull from local news police blotters, which could turn this into the Crunchbase of street rip-offs. Pack it alongside your vaccine card.

QR Attendance Scanner

Event organizers know the pain of standing at the door with a paper spreadsheet while the keynote speaker is already on slide four. This web app creates an event, spits out a single QR code for attendees, and turns any phone into a scanner. No install, no signup for attendees, no “can you spell your last name again.”

I ran a fake meetup with two laptops and my desk phone—took ninety seconds to create the event, scan three codes, and export a CSV. The scanner even works offline; it queues the data in the browser and syncs when you’re back on Wi-Fi. Perfect for university clubs, barcamps, or that wedding where you swore you’d track who actually showed up. The UI is barebones, but that’s kind of the point: open, scan, done.

Fear-Setting (a Tim Ferriss exercise)

Tim Ferriss popularized this three-column worksheet—define the worst case, prevent it, repair it—years ago on a TED stage. Someone finally cloned it into a reusable Notion page so you don’t have to draw columns on a napkin each time you consider quitting a job or moving to Lisbon.

The template is free, duplicate-ready, and comes with gentle prompt text so you don’t stare at a blank page. I walked through a “What if I open-source my side-project and nobody cares” scenario; ten minutes later I had three plausible ways to recover my reputation and a clearer sense that the upside outweighs the crickets. If you already live in Notion, this is a no-brainer bookmark. If you don’t, export to PDF works fine.

Playlist Name AI

Streaming apps are great at recommending songs and terrible at naming the results. Playlist Name AI asks for mood, genre, activity, style, and a couple favorite artists, then spits out titles like “Velvet Midnight Circuit” or “Lo-Fi Laundry Escape.” You can generate endlessly and save the keepers once you sign in with Google.

I fed it “ rainy, indie, coding, Nils Frahm, no vocals” and got back “Drizzle & Debug,” which is honestly better than anything I’ve come up with sober. The tool is free, no watermark, and the names stay short enough to display fully on CarPlay. Downside: it won’t actually build the playlist for you, so you still have to drag tracks around. Still, if you’re sharing mixes with friends, this saves you from the dreaded “Untitled Playlist 7.”
