Show HN: I rewrote my notepad calculator as a local-first app with CRDT syncing
Hacker News (score: 32)Description
Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which should make it relatively easy to get document sharing working too.

Show HN: Anchor Relay – A faster, easier way to get Let's Encrypt certificates
Show HN: Anchor Relay – A faster, easier way to get Let's Encrypt certificates From the cryptic terminal commands to the innumerable ways to shoot yourself in the foot, I always struggled to use TLS certificates. I love how much easier (and cheaper) Let's Encrypt made it to get certificates, but there are still plenty of things to struggle with.<p>That's why we built Relay: a free, browser-based tool that streamlines the ACME workflow, especially for tricky setups like homelabs. Relay acts as a secure intermediary between your ACME client and public certificate authorities like Let's Encrypt.<p>Some ways Relay provides a better experience:<p><pre><code> - really fast, streamlined certificates in minutes, with any ACME client - one-time upfront DNS delegation without inbound traffic or DNS credentials sprinkled everywhere - clear insights into the whole ACME process and renewal reminders </code></pre> Try Relay now: <a href="https://anchor.dev/relay" rel="nofollow">https://anchor.dev/relay</a><p>Or read our blog post: <a href="https://anchor.dev/blog/lets-get-your-homelab-https-certified" rel="nofollow">https://anchor.dev/blog/lets-get-your-homelab-https-certifie...</a><p>Please give it a try (it only takes a couple minutes) and let me know what you think.
Show HN: An Open-Source E-Book Reader for Conversational Reading with an LLM
Show HN: An Open-Source E-Book Reader for Conversational Reading with an LLM Hi HN! I've been working on BookWith, an open-source e-book reader that integrates AI as your reading companion.<p>The problem: Traditional e-readers are passive. When you encounter something unclear, you have to context-switch to search for it. Your highlights and notes remain isolated, and you can't easily connect ideas across different books.<p>My solution: BookWith embeds an AI that maintains full context of what you're reading. It features:<p>- Context-aware AI chat: Ask questions about the current page/chapter and get instant answers<p>- AI podcast generation: Automatically converts book content into conversational podcasts using Google Cloud TTS<p>- Multi-layer memory system: Short-term (last 5 conversations), mid-term (summarized every 20), and long-term (vector search) memory that maintains continuity across reading sessions<p>- Smart annotations: 5-color highlighting system that AI can reference and analyze<p>Technical stack: Built as a fork of Flow (epub reader), with added LLM integration and vector database for semantic search. Supports multiple LLMs and languages (EN/JA/ZH).
