Show HN: Dodosend – a Fast keyboard first Gmail client A while ago, I worked on an gmail clients and ended up learning a lot about email, so I kept building my own. The things I cared about most were speed, privacy, good UX, and full keyboard shortcuts support. It's still a beta, you can try it through interactve demo or download here: https://dodosend.com P.S. If you request access, please only do so if you're willing to actually try it and send me some feedback. https://dodosend.com September 28, 2026 at 04:03AM

Show HN: ParkourNote – A research workspace, built solo in a month with Claude Hi HN, I'm sushi. I built ParkourNote, a personal knowledge management app that currently focuses on research: finding papers, reading PDFs, asking AI about them, and writing. A few things it does: Describe a topic, and an agent creates a project, searches arXiv, and imports relevant papers The PDF reader previews citations on hover, overlays translations on the page, and shows original and translated text side by side The agent sees the page you're reading and your selection; you can also connect Claude or ChatGPT via MCP A block editor with math support that compiles LaTeX / Typst to PDF Demo (7 min): https://youtu.be/yZs2nQJtgkg ParkourNote is just me. I built it in about a month: the web app, a Flutter mobile app, and a Chrome extension. It isn't even my full-time job. I work on it for an hour or two in the morning before work, plus evenings and weekends. Two things surprised me along the way: - The web app uses BlockNote for Notion-style editing, but I wanted Flutter for mobile. I asked Claude to implement a compatible editor in Flutter. It took about a day, and it works: documents round-trip between web and mobile. - In high school I worked as a video editor for MarginNote. Back then, a single 5-minute video took about a month, from scripting to recording, editing, and animation. For ParkourNote, I made launch videos for the Chinese, English, Japanese, and Korean markets in one weekend, plus a second Chinese version cut for portrait viewing. I didn't open a video editor once. It was all done with Claude Opus 5.5. PG recently posted something along the lines of: in the AI era, you want to be either very close to the users or very close to the intelligence. That resonated with me, but honestly, building this left me a bit lost. I find it hard to think of a consumer software feature that current AI can't build. So if anyone can build anything, where is the moat? I'm genuinely unsure. The other side of it is exciting, though. Running ParkourNote alone, I feel less like a solo developer and more like a CEO of a small company: I manage product, engineering, marketing, and operations, and somehow it's all manageable. A one-person company feels genuinely possible now, in a way it didn't a few years ago. Signup is required since the AI features cost money to run; new accounts get 100 free credits after email verification. Happy to answer questions about the product, the workflow, or the moat question. I'd genuinely like to hear how others are thinking about it. https://ift.tt/WnlP4Qd September 27, 2026 at 09:31PM

Show HN: An interactive debugger for the Mornington Crescent esolang Originally put together ten years ago, I've migrated this project over to Codeberg and in the process fixed a couple of bugs. The most glaring issue was that in the intervening years, CORS has become a thing so the Transport for London Tube map can no longer be loaded directly from their site; instead, there's a local copy of the SVG. I'm happy with where it is at the moment, there might be more small patches in another ten years. https://ift.tt/LWcdkua September 27, 2026 at 04:53AM
