Show HN: Coolphabets – Teaching kids to read and write in their mother tongue COOL + ALPHABETS = COOLPHABETS COOLPHABETS teaches you to read and write in your mother tongue - for kids who are just starting, and adults who never did. Millions of families live outside the country they were born in. While parents can read and write in their native language, their kids - the second generation - can barely do so. Kids often speak their mother tongue fluently because it is the language they use at home. But reading and writing is rarely a "felt need" for them. And kids are unlikely to feel that need unless parents nudge them - preferably at an early age. Many parents genuinely want their kids to be able to read and write in their mother tongue. This usually means a textbook or a weekend language class. Both can feel like a chore. Most language apps teach you to 'speak' a language. COOLPHABETS teaches you to 'read' and 'write'. Reading and writing are a genuinely difficult problem to solve - especially on an app. Getting a child to write letters correctly is the harder part. That's where we built CoolphaSense - a collection of tiny AI models that run entirely on the device and provide instant feedback on handwriting. COOLPHABETS is designed for kids. No ads. No tracking. COPPA compliant. The apps are designed to work fully offline. No cloud roundtrips to a 'Mothership AI model'. COOLPHABETS is currently available in Indian languages. - Telugu - Kannada - Hindi - Tamil - Marathi Most other Indian languages will be onboarded by December 2026. Other world languages (Asian, Middle Eastern, European) are early next year. The bigger motivation is cultural. A language can survive for several generations as a spoken language, but if its script is lost, something important is lost with it. If one generation stops reading and writing in its native script, reconnecting with that part of the culture becomes much harder. If you are a parent who feels this way, COOLPHABETS is for you and your kids. https://ift.tt/OX0q3pG Android: https://ift.tt/t91oB7F... iPhone: https://ift.tt/Ml60bDJ We would love to hear from parents settled outside their native countries, parents raising kids in multilingual households, and from people working on handwriting recognition, on-device AI/ML, and language learning.

Show HN: Pocketty – iPhone SSH terminal that pings you when an agent is blocked https://ift.tt/ErMOfZe

Show HN: Pocketty – iPhone SSH terminal that pings you when an agent is blocked Hello~! pocketty is an SSH terminal for iPhone and iPad, made for herdr. herdr keeps your agent panes alive on your computer and knows the state of each one: working, needs you, or done. I made this in anger/desperation for the latter half of my recent paternity leave. Nap traps are sweet, but there's only so much doom-scrolling and movie-watching I can handle... In any event, I've been using it for the last couple months and no longer have to be my desk anymore to be productive. Now the nap-traps are still productive (when i want them to be) ! How it works: - The app talks to your computer directly over plain SSH. Tailscale is the easy way to reach it from anywhere but any SSH host you can reach works. - A small Rust daemon on the host watches herdr. When a pane needs you, it seals the alert to your phone's key with HPKE (X25519, ChaCha20-Poly1305). A stateless relay (pocketty's) on Cloudflare Workers passes the sealed bytes to APNs (Apple Push Notification servers), and a notification extension opens them on the phone. The relay can't read them and keeps nothing. - Your SSH key is made in the Secure Enclave and can't be exported. - The terminal uses libghostty-vt for state and draws with wgpu on Metal, so full-screen TUIs look like they do on your desk, albeit narrower. - Diffs for each agent turn, a file browser, and previews of `localhost` dev servers your agent starts, all through the same SSH connection. No port forwarding to set up. herdr and the daemon are optional. Without them, it's a normal SSH client. There's no account to set up and no analytics or tracking in the app. The app runs a 14-day free trial, with full feature access. Then, if you're as happy as I am with it, then it can be yours forever with a one-time purchase: $99 for the first two weeks (launch promo) then $129 after that. Happy to answer anything about the sealed push setup or running libghostty on iOS. https://pocketty.app/ October 9, 2026 at 01:11AM

Show HN: Durable Actors – OSS Durable Objects with configurable compute https://ift.tt/BuKpvCD

Show HN: Durable Actors – OSS Durable Objects with configurable compute Hi HN, we're Thomas and Olivier from Terse ( https://ift.tt/Zu0DlU1 ) We've built Durable Actors, an open-source alternative to Cloudflare's Durable Objects. A Durable Object/Actor is a tiny server that handles one request at a time and has its own SQLite database. There's exactly one of each in the world and it is addressed by name. This is the perfect primitive for deploying multiplayer agents. Each agent can have its own Durable Actor, and each user can connect to that Actor via websocket. This is fully horizontally scalable. Your users can deploy and share agents at will without putting pressure on a central DB or websocket server. Durable Actors are also great for coordinating agents within a system. Since only one request is handled at a time, you can protect critical data such as a CRM and allow multiple agents to run concurrently without worrying about data races. The only alternative to this is Cloudflare's Durable Objects. However, there is extreme lock in (they pull you into D1, R2 + workers as well) and it wasn't originally built for agentic workfloads when it was released 5 years ago. Some notable projects built on Durable Objects include RampInspect, OpenInspect as well as the multiplayer frameworks Liveblocks and PartyKit. You can now build these kinds of projects on Durable Actors. Durable Actors is a version of DO that is built for concurrent agentic workloads. It is fully open source (MIT License) and includes a helm chart for you to easily self-host. Some key features: - Configurable compute: Specify CPU, RAM, data residency, idle-timeouts all in a decorator - No outer worker: We generate a type-safe client that you can just plug into your existing tech stack. - (coming soon, like today) Export SQLite table via CLI + MCP for exposing OLTP logs to your agent to help you debug. And our Performance Numbers (all p95): - Durable write: 85.6ms - Stateful Read (data in sqlite): 2.14ms - Actor Warm up: 334ms Here is a little counter demo so you can see the latency yourself: https://ift.tt/fDhOSqr Would love your feedback! https://ift.tt/7PXQnEa October 6, 2026 at 10:58PM

Show HN: Jev-pages – Building landing pages real time with Jev https://ift.tt/y2cTopi

Show HN: Jev-pages – Building landing pages real time with Jev An experiment using Jev to generate landing pages in real time. Jev is great at picking between different options so I attempted to break down the langing page UI into a set of choices for the model to choose from. How this works: 1. Users type what kind of page they want and Jev decides what each line is (headline, fact, assertion etc.) 2. Jev makes choices for each layer of the page (opening, stage, light, depth etc.). Parameterizing design is hard (impossible?) but this took some tuning with Claude 3. A full page is constructed with a single call of about 90 questions. Of course using an LLM would be more prudent for step 1, but I wanted to check the limits of Jev's understanding (it works pretty well in my opinion!). https://ift.tt/za42MEB October 5, 2026 at 12:30AM
