Yesterday's Top Launches: 5 Tools from September 15, 2026
Yesterday's batch of five new products centers on local-first data ownership, with three connecting to AI models without routing anything through a company index and two built to work entirely on your own machine.
Five products shipped yesterday, and the batch leans heavily toward a single theme: keeping your data where you can see it. Two of them are local-first by design, one refuses to upload your screen recordings, and one is explicitly built to measure something none of your existing analytics dashboards cover. If you track new developer tools, the local-AI angle is worth noting, because three of these five connect to a model without ever routing your stuff through a company index.
Resurf
Resurf is a personal context library that lives entirely on your Mac. Save articles, PDFs, screenshots, voice memos, GitHub repos, tweets and code snippets with ⌘⇧C from any app, and it all lands in one searchable inbox you organise later with Spaces and Tags. Everything sits at ~/Library/Resurf, sync is optional through your own private iCloud, and there is no account.
The AI side is opt-in and unusually flexible. You bring your own key, ask questions across your own library, and hand saved context to agents over MCP or the CLI on Mac. It is written in native Swift across Mac, iPhone and iPad.
Honest caveat: personal knowledge management is a graveyard of abandoned vaults. Resurf’s bet is that the inbox model plus native rendering beats folder discipline. Free on iPhone and iPad, paid license for Mac. Worth a look if you already have a collection habit that keeps failing.
ScreenCursor
A Chrome extension that records your screen and does the zooming for you while you record. Every click, drag and keystroke becomes a camera move that arrives a beat before the action, so the viewer is already looking at the right spot. You still get full manual control over every zoom, plus wallpaper framing, browser chrome with the real page title, and clip splitting.
The whole pipeline runs in the browser. Nothing uploads, no account, no watermark, no subscription. $49 once at early pricing, up to three machines.
It is not Screen Studio. No webcam overlay, no motion blur, 1080p ceiling, and recording quality depends on your machine having hardware video encoding. But it runs anywhere Chrome does, including Windows and Linux, and Screen Studio does not. For quick demo clips, that trade is often fine.
Visiby
Answer engine optimisation is now a budget line, and Visiby is a visibility layer for it. It samples more than 50,000 prompts weekly across ChatGPT, Claude, Perplexity, Gemini, AI Overviews and Copilot, then reports your citation share per engine, which competitor got cited in your place, and the structural recipe behind it.
The interesting parts are the Citations Explorer, which ranks the actual URLs the models pull from and flags honey-pot versus dead-weight pages, and the Action Plan, which prices each fix against projected visibility lift. Recipe Intelligence tracks which on-page elements get extracted per engine: H2s, FAQ schema blocks, tables, lists.
Pricing runs $49 to $499 a month. The Lite tier’s 25 prompts a month is thin for anything serious, so realistically you are comparing Starter against whatever SEO suite you already pay for. It complements Semrush or Ahrefs rather than replacing them.
DemoTV
A 24/7 television station where short product demos play on a loop and viewers decide the running order. Two products go head to head, you back the one you would try, and an Elo-style audience score sorts Channels 1, 2 and 3. Watching and voting need no sign-up.
Submission is free, capped at 40 MB or a YouTube link, and reviewed before going live. Founders get an embeddable widget with a configurable call to action, plus an optional backer code to reward viewers who picked them. Paid airtime exists at 5, 10, 25 or 100 units, but the site is emphatic that it never touches rank.
The station showed 110 live demos and about 54,000 views at capture, which is small. Whether the audience ranking stays meaningful at scale is the open question.
GhostWriter by MyHandler
A Windows tool that drafts text inside whatever app you are already using. No prompt field, no sidebar. Put your cursor in the reply box, double-tap Left Ctrl, and it reads the thread above you, works out what you would write next, and types the draft at your cursor in your voice.
It classifies the situation first, so a continuation continues instead of restating your own sentence, and a reply answers the other person instead of summarising the thread back at them. It maps who said what, matches how you write to that specific recipient including the sign-off, and cross-checks any proposed meeting time against your calendar. It never sends.
The architecture is split: screen capture and the index stay in an encrypted vault on your PC, but the assembled context goes to a cloud model with zero retention to produce the draft. Free on Windows 10 and 11, macOS and Linux coming.
Ranking note
Audience scores had not settled across the board on launch day, so the only public ranking signal here is DemoTV’s own Elo board, which currently rewards demos viewers actually want to try rather than ones with marketing budgets. On merit, Resurf and ScreenCursor feel like the two with the clearest reason to exist: both remove a specific step people already hate.
