keystrokes, zooms, and channels

Today: a keyboard shortcut that finishes the sentence you were about to type, a screen recorder that puts the zooms in for you, and a television channel where the audience decides which demos are any good.
GhostWriter by MyHandler — Two taps and it's already written
GhostWriter writes the thing you were about to write. Double-tap left Ctrl in any text field in any app and it reads what is on the screen and works out what comes next. It sits inside MyHandler, a local-first assistant for Windows that indexes your screen, files, mail, calendar and meetings into an encrypted vault on your own drive, which Tery Emilson calls OpenClaw for people without a Mac mini in a cupboard. Forty years he has been shipping software, starting on a Tandy CoCo with 4K of memory, and in 1999 he got annoyed enough that Pocket PC had no database that he sat down and wrote one. It stayed the biggest on the platform for a decade, across 135 countries, and the UN ran it.
Arcjet — Your agents stopped answering and started doing
(sponsored)Your agents call tools, write to databases and move money, so a wrong answer is now a wrong action, which is a considerably worse meeting. Arcjet runs policy before every LLM call, tool call, query and API request: prompt injection, sensitive data, bots, rate limits, spend quotas, and your own rules in Rego on top. It reads the OpenTelemetry you already emit, so switching it on is one environment variable, no code changes and nothing to deploy. Each check also reads the earlier steps in the same workflow, so an agent's tenth action gets judged against the first nine and not on its own. JavaScript, Python and Go SDKs all at 1.0, agent framework guards included, free tier to start on.
ScreenCursor — Screen recorder with auto zoom effects
ScreenCursor records your screen and places the zooms for you. It watches where the cursor goes and where you click, and when you stop recording the zooms are already in, so what comes back is finished. Phoenix built it because every good product demo he had ever seen was made in Screen Studio, which is Mac only, and he is on Windows. Chrome extension, no installer, no admin rights, nothing uploaded. He is asking Windows and Linux people to go and break it, because that is who he built it for.
DemoTV — The audience-ranked TV channel for product demos
DemoTV is a television channel for product demos, ranked by the people watching them. Two demos go head to head, you pick the one you would actually try, and an Elo score built from thousands of those votes decides who sits on channels one to three. Steffan Winstanley built it because every product has a slick demo and not one of them tells you whether the thing is any good, since the polish belongs to the product and not to anybody reviewing it. You can pay for airtime, which is labelled as such. You cannot pay for a better rank.
Build with Astra, win big prizes

We teamed up with OpenAI Developers to launch the GPT-6 Astra Challenge on Product Hunt.
GPT-6 Astra is built for complex, multi-step work—from software engineering and research to workflows that require judgment and follow-through. Build something useful with Astra, launch it on Product Hunt, and compete for API credits and ChatGPT Pro subscriptions. If you've hit your token limit, OpenAI will be resetting usage for people who participate
If you're already building with Astra, this is a chance to share what you've made and put it in front of a wider audience. You can schedule your launch for Friday, September 18.
