Yesterday's Top Launches: 5 Tools from September 15, 2026

Five products went live yesterday, September 15, and the range is unusually wide: two of them belong squarely in the new developer tools conversation, one is a Windows writing assistant, one is an iPhone app for documenting incidents, and one is a map of borshch. None of them carried a community ranking yet, so what follows is my own read on each rather than a leaderboard.

Resurf

A local-first context library for Mac, iPhone and iPad. You throw notes, links, PDFs, images, voice memos and video into one inbox, tag and sort them later, and search everything with ⌘K. The part that separates it from the long graveyard of read-later apps is the handoff: because the library sits at ~/Library/Resurf as plain local data, you can pass saved context to AI agents through MCP or a CLI on Mac, or ask questions across your own collection. Written in native Swift, works offline, no account, optional sync through your own iCloud.

Who it’s for: designers, researchers and writers who collect material constantly and lose it. The honest caveat is that most of us already have three places we save things, and adding a fourth only works if the search is genuinely fast and the capture shortcut (⌘⇧C) becomes muscle memory. Free to try on Mac, free on iPhone and iPad, with a separate purchase license available. macOS 14.3 or later.

DemoTV

A 24/7 channel for product demos where the audience decides what airs on Channels 1, 2 and 3. Products go head to head in what the site calls Channel Battles, paired by category, and viewers back the one they’d actually try. No sign-up to vote. The line that matters: airtime never buys rank. Paid placements exist, they’re labelled, and they buy exposure and clicks only.

Submitting a demo is free, a YouTube link or a 40MB MP4 is enough, and approved makers get an embeddable widget for their own site plus a dashboard for recruiting testers. The mechanic is clever and the incentive design is honest. The risk is the same one every marketplace faces early on: it needs volume, and right now the number of rated products is small.

GhostWriter by MyHandler

This one reads your screen instead of asking you to prompt it. Put the cursor in a text field, double-tap the hotkey, and a draft appears in your voice, grounded in the thread above the cursor, addressed to the right person. It works out whether you need a reply, a continuation, a fill-in or a rewrite before it writes anything, and it never sends. If the reply proposes a meeting time, it checks your next two weeks of calendar first.

Windows 10 and 11 only, free, with macOS and Linux promised. Worth flagging the privacy shape: screen capture happens locally against an encrypted vault, but the assembled context is sent to a cloud model, which the company says operates with zero data retention. That’s a reasonable design, though not the same as fully on-device. If you write replies all day in Slack and Outlook, the double-tap gesture is the whole selling point, and it’s a good one.

Kirokune

An iPhone app for logging work and personal incidents with notes, voice recordings and photos, organized into a timeline. One tap starts a recording, which matters when typing isn’t realistic. Records land in a case, the free plan gives you one, and Plus adds unlimited cases, detailed reviews and PDF export. You can also import chat exports from Apple Messages, Messenger or Instagram without connecting accounts. Records stay on the device, no account, no cloud.

It’s direct about its limits. No automatic sync or backup, so keep your own copies. It doesn’t diagnose, decide what happened or give legal advice, and it can’t tell you whether recording a conversation is lawful where you are. Available in the US and India, iOS 17 or later, free with in-app purchases.

Naverny Borshchu

Not a dev tool, but genuinely well-built. An interactive map of Ukrainian borshch covering 278 bowls across 31 cities, 103 of them rated. Every bowl is scored on the same seven criteria: meatiness, beetiness, saltiness, thickness, aftertaste, presentation and overall. Because the questions are identical everywhere, ratings from different cities become comparable, and a Borshch Index adds price context (202 UAH per serving in Kyiv, 56.1 UAH per 100g against a homemade pot). Whoever tastes an unrated bowl first stays on it as its discoverer.

Free, open source, no ads and no affiliate links, which is why the listings aren’t paid placements. It’s a small project with a clear cultural mission and a data model that’s more disciplined than most restaurant apps manage.

If you only try one thing from yesterday, Resurf is the most interesting bet on how local context and AI agents fit together. GhostWriter is the one most people could use tomorrow without changing anything else about how they work.
