Show HN: Local MCP – Claude/ChatGPT read your iMessage, Teams, files on-devicehttps://www.local-mcp.com/enI kept hitting the same wall: AI assistants are great until they need my context — the email thread, the calendar, the iMessage, the file on my disk. Cloud connectors can only reach things with a public API, so they physically can't touch the stuff that lives only on my machine.So I built Local MCP — a native macOS app that connects Claude Desktop, Claude Code, Cursor, and ChatGPT to your real local apps over MCP: Mail, Calendar, Contacts, iMessage, Microsoft Teams, Slack, WhatsApp, Notes, Reminders, OmniFocus, OneDrive/Google Drive, Office docs, and local files. ~180 tools.The part I care about most is where the data goes:- Desktop/CLI clients (Claude Desktop, Cursor, Claude Code): everything runs on localhost — nothing leaves your Mac, no API keys, no OAuth to us.- Web AIs (ChatGPT, Claude.ai) that can't reach localhost: there's an optional, opt-in encrypted relay you turn on yourself. It's off by default and it's the only path anything leaves the machine. I flag this explicitly beca

Show HN: Wax Spinner, a "now playing" social app for vinyl record collectorshttps://www.waxspinner.comI collect records and I build apps in my spare time (and listen to records while I build apps), and this is what happens when those two things run into each other.Many people post photos of what they have spinning on their turntables on social media, and most never get any engagement. It occurred to me that people might want a better way to do this, and bringing them together in a niche social site might help.So I made Wax Spinner. Connect your Discogs (the de-facto vinyl collector's catalogue) account, post whatever you're playing with an optional note, and it lands in a feed where people can like it and comment. You can also browse anyone's full collection on their profile, and filter the feed by genre, pulled straight from Discogs metadata.The conversation and the discovery are the primary purpose.The details this crowd might find interesting: every spin generates its own OpenGraph share card on the fly, with cover art, artist, year, and notes rendered server-side and cached.

Ask HN: How would you launch an open-source app with a small budget?https://news.ycombinator.com/item?id=48735500I have been working on Kiyeovo - an open-source desktop P2P messenger with an optional anonymous mode - for almost a year now. The plan is to go full-release on 7th of July.Currently, I’m trying to figure out how to make the launch more visible - market the product (even though it's FOSS).The common answer I saw was to "build in public", but as I, and many of us, don't have any sort of following online - that won't have as big of an effect. Still, useful advice.Since the final release of the product is less than a week from now, I decided to focus a lot more on the marketing aspect.I allocated a budget of 550$ which I will spend on the release. - 150$ of that will go into deploying bootstrap, relay and STUN/TURN servers around the world so that you can use the app without setting up your own infrastructure - path of least friction for users who just want to try the app out.I'm left with 400$ which are going straight to getting the word out. And this is where I need your help and advice

Show HN: Looped Whisper (FOSS) – Voice transcription menubar app for macOShttps://github.com/loopedautomation/whisperI built a free, open-source (MIT) macOS menu-bar app that runs Whisper models locally to assist with dictation. There is also the option to use an LLM (BYOK).You hold a global hotkey, speak, and the text gets pasted at your cursor similar to other similar/popular apps.Some details: - Transcription runs locally via WhisperKit (CoreML), so it works offline once the model is downloaded. BYO model — tiny through large-v3, auto-downloaded and cached. The base model has been working surprisingly well for me with gpt-5.4-mini as the transformation model. - Push-to-talk (hold) and start/stop toggle hotkeys, both configurable. - fn/Globe key supported. - Realtime mode for live captions as you speak. - Optional LLM cleanup to fix typos/punctuation — point it at Anthropic or any OpenAI-compatible endpoint, key stored in the macOS Keychain. - A vocabulary feature to bias recognition toward your names, jargon, and identifiers (handy for dictating code). - This works as a menu-bar agent, no Dock ico

Show HN: Better PDF Presentations (+Typst)https://presio.xyzLike many of us here I prefer not use PowerPoint. Recently I've been making slides in Typst (https://typst.app) which is great, except there's no good way to actually present the resulting PDF, and no support for speaker notes, videos or GIFS.To fix this I built Presio: https://presio.xyz. Present any PDF in the browser as two synced windows, a controller (speaker notes, timer, media controls) and a viewer for the projector. It handles embedded video and GIFs, including YouTube/Vimeo.Local by default: your PDF never leaves your browser. Optionally shareable so the audience can follow along on their own devices.A short GIF explains it best: https://imgur.com/a/ZbvhPncTry the an example presentation: https://presio.xyz/present?from=https://github.com/benedict-...Works with plain Typst, Polylux, Touying and PDFs from LaTeX too (speaker notes supported).

Show HN: LoveInvoice – a free invoice tool for freelancers and small businesseshttps://loveinvoice.comI recently built LoveInvoice, a pleasant invoicing tool for freelancers and small businesses.After spending time working on freelance-side projects (and recently losing my job, which gave me more time to focus on it), I wanted to build something simple that doesn't require a subscription or a bunch of features you don't need when you're just getting started.LoveInvoice lets you generate and send PDFs, automate reminders, and manage clients, with full customisation where it matters (emails, invoices, branding).The core app is free to use.There is an optional Stripe integration for taking payments online, which takes a capped 1% fee to cover costs. Otherwise, you can just include bank details on invoices and handle payments manually.It's still early, so I'd really appreciate any feedback on the product, UX, or anything confusing.Thanks!Link: https://loveinvoice.com

Show HN: TS Package to Convert Final Cut, Premiere, Resolve and OpenTimelineIOhttps://github.com/ChatOctopus/timelineA small TypeScript library that imports and exports FCPXML, FCP7/xmeml, and OTIO, plus a CLI.You can use it for reading, writing, and converting video-editing timelines with frame-accurate timing.e.g: npx @chatoctopus/timeline convert edit.fcpxml --to otioFeatures:- Format conversion - Import/parse/Export - Give it clip paths (+ optional trims); it probes them with FFprobe and assembles a timeline - Programmatic timeline constructionCaveats: it moves the structure of an edit (cuts, clips, timing, media) but not effects, color, titles, or audio mixing. Transitions only survive into OTIO (they flatten to cuts in FCPXML/xmeml), and on the Final Cut side, it reads Resolve-style asset-clip timelines rather than FCP's compound/multicam/title containers.Contributions: Looking for some real-world test files of FCP, Premiere, and Resolve to find and fix any remaining bugs.

Show HN: Open-source job search plugin for Claude Codehttps://github.com/agent-data/job-searchHey HN,I wanted to share an open source plugin + skills I put together that turn Claude Code into a job search assistant. The goal is to minimize the amount of time needed to find interesting and relevant jobs.How it works:1. Clone the repo, install the plugin, and run `/job-search`2. Claude will ask a few questions to understand the roles you’re interested in and save your preferences locally.3. Claude will then pull live job postings (currently, LinkedIn Jobs), compare posts against your preferences, and generate a digest of the posts that are relevant.4. [Optionally] Claude will also run your search on a schedule (e.g., daily) to surface new posts matching your preferences over time.Features on the roadmap:- ATS platform support (e.g., Workday, Ashby, Greenhouse)- Support for additional agents (e.g., Codex, Cursor)- Skills for having Claude compare resumes to job descriptions to estimate “fit”- Skills for having Claude recommend resume edits to better align with a given job descript

Show HN: PMB – local-first memory for AI coding agents over MCPhttps://github.com/oleksiijko/pmb/blob/main/README.mdHow it works: - Storage uses one SQLite database file, plus a local LanceDB index of vectors. No need for a server, cloud services, or any API keys. - Retrieval is a hybrid approach using BM25 (rank-bm25) and vector-based search (sentence-transformers) combined with a co-occurrence graph of entities, using reciprocal rank fusion. The idea is to find the right memory, not the closest one. - It plugs into the agent's lifecycle via MCP: before the agent responds, relevant memories are added to its input; after each turn, decisions and new learnings are automatically recorded. No need to manually remember "remember this". - It maintains a dictionary for each project which builds itself based on your memories, which improves recall performance for the project-specific vocabulary. - It can run fully offline, pointing to a locally installed Ollama model and even the optional large language model features such as consolidation, de-duplication, and chatting about your memories stays on your mac

Show HN: Notedog – Git-friendly portable Markdown journal, edit from a laptophttps://notedog.run/Hi. I've created this Android app for a couple of motivations: 1. no need to sync; 2. easy to throw away (no lock-in); 3. works without internet access.The app runs a small web server and allows you to edit your journal with the app UI, and also from browsers on other devices. Since in both cases the changes will be persisted in the phone, no need to sync.You can connect to the editor server by using a private IP address in the local network, Tailscale network, or optionally, use a built-in HTTPS tunnel (paid subscription) via the internet and keep a handy access with the same URL.I'd appreciate your feedback.

Show HN: Topaz – A small application language that compiles through Rusthttps://github.com/studiohaze/topazHi HN, I'm Matt, CTO at STUDIO HAZE in Seoul. I've wanted to build a programming language for twenty years, ever since Ruby got me wondering what a small language out of Korea might look like. Today I'm opening the repo for the first time, as Topaz v5.2.Topaz reads like Python or TypeScript, runs on a reference interpreter (topaz run), and builds a self-contained native binary by lowering to Rust, then handing off to the Rust toolchain (topaz build). function factorial(n: int) -> int { if n < 2 { return 1 } return n * factorial(n - 1) } print("10! = {factorial(10)}") // 10! = 3628800 The idea: application logic should have a small, fixed surface with one obvious way to write each thing, and the compiler does the hard part underneath. Writing glue in Python and TS, I kept re-making the same policy decisions — errors, absence, cleanup. Topaz decides those once: Result for recoverable failure, optionals for absence, defer for cleanup.Identifiers are Unicode from the lexer up, with no impl

Show HN: Satd – a Bitcoin full node in Rusthttps://github.com/epochbtc/satdI'm Ben, and I've written a modern, independent implementation of the Bitcoin protocol in Rust. The primary problem I wanted to tackle was monoculture: the Bitcoin network and community has been based on a single C++ implementation for 15 years, a descendant of the original Satoshi-authored codebase. This codebase and the small Core committee are a single-point-of-failure, and is a potentially attractive target for those who would seek to damage or disrupt the network.On top of that, while the Core team has done a great job at stewarding and improving the codebase, it can't help but be a big, complex tree of largely legacy C++. I wanted something modern, easier to maintain and with batteries included:- Native TLS (including mTLS) out of the box- Built-in (optional) API services for Electrum (based on electrs) and Esplora (no sidecars or separate services needed to run a wallet backend)- Atomic indices with a single RocksDB data store (address index can't lag core block index, for examp

Show HN: I built a native project management app that respects your privacyhttps://getmilestones.app/store/Hello HN!I wanted to show you the project management app that I've been building for the past 2 years: Milestones! It's completely native and works on iPhone, iPad, and Mac.It doesn't need an account, it's local-first, with optional iCloud Sync that can be turned on in settings. iCloud Sync means that your data can be synced but still stays private, as it syncs to your own iCloud account. Additionally, analytics and crash reports are opt-in and you're asked before any data is sent to any analytics server.I built this app for myself, since I am handling multiple projects constantly, but wanted a way to manage them without having to use bloated, complex tools, plus I needed a way to divide tasks into "phases" or milestones (e.g. App versions).It's free to download and has a generous free-tier, the pro version comes with a monthly, yearly or lifetime option and is mainly for power-users. I also just released an MCP Server for the Mac version.I'd love for you all to try it and tell me what

Show HN: Fungible – A local personal finance app in the terminalhttps://github.com/tomfunk/fungibleFungible is a terminal-based personal finance app that fills the Mint-shaped void in my life. It runs using your own plaid credentials (optional) and has its own integrated chatbot (also optional and BYO key).You connect banks via Plaid or import CSVs. Transactions get auto-categorized by rules you define. On top of normal categories there's a flexibility layer (fixed / flexible / discretionary) so you can see at a glance what's actually controllable spending. There are also tags (also separate from categories) for isolating things like trips or hobbies.The financial health screen does savings rate, liquidity runway, and FIRE projection with adjustable assumptions. Probably overkill but I like it.It also has an MCP server so Claude/ChatGPT can talk to you about your finances, create rules/tags, etc. That’s always the most annoying thing for me when trying a new personal finance tool. Hopefully this brings down the barrier to usefulness. The agent/chatbot in the app has the same tools a

Show HN: My independent search engine focused on user controlhttps://slicksearchhq.comI've always been frustrated with search engines. Google used to be the one I always used, but it's now completely overrun with ads and AI Overview. Alternatives like Mojeek, Marginalia, DuckDuckGo, or Startpage don't seem to give me the results I'm looking for.What's even worse is that search engines like DuckDuckGo, Startpage, and Ecosia are using AI Overviews too. These features ARE optional, but I still felt annoyed that I had to opt out of everything.This is why I created my search engine Slick. Slick is an independent search engine with its own index. It aims to be everything users want from a search engine, whether that's privacy, speed, transparency, or customization.We aim to let users have full control over their search engine. Currently, we have implemented this using custom per-domain ranking (similar to Kagi) and custom bangs (DuckDuckGo bangs, but faster and with the ability to add your own).For revenue, we WILL be using ads in the future, but we want to approach them diff

Show HN: Crowdsourced tracker for what each Windows/M365 update breakshttps://win-update-tracker.vercel.app/Sysadmins find out about a broken Windows update three ways: a user ticket the morning after Patch Tuesday, an r/sysadmin thread 48 hours later, or Microsoft's own Known Issues page 1–3 weeks deep. There's no central feed of "this KB broke this thing on this config." Bleeping Computer and AskWoody are the closest, but slow and unstructured.So I built one.What it does: - Pulls posts every 4–6h from r/sysadmin, r/msp, r/Intune, r/ActiveDirectory, r/exchangeserver, r/AZURE via the Reddit JSON API - Pulls RSS from MS Health Dashboard, Bleeping Computer, AskWoody, BornCity, MS Security Blog, and the Windows IT Pro / Intune / Exchange TechCommunity boards - Groups by (primary KB, component) so 12 threads about the same 802.1X bug become one row with 12 source links - Ranks by score + post_count + recency - Optional Thursday digest email via ResendEvery regression row links back to the underlying Reddit/RSS posts — the classifier is not authoritative, the source threads are.

Show HN: ClassKeep – Booking, credits, and smart waitlists for boutique studioshttps://www.classkeep.appHi HN — I built ClassKeep.The trigger: every small studio owner I know (pilates, yoga, pottery, even a dog trainer) runs the operational side of their business on WhatsApp + a Google Sheet, or on one of the expensive incumbents (Mindbody/Glofox) they actively dislike. The single biggest leak is last-minute cancellations: someone bails at 6am and the seat just goes empty, because there's no fast way to notify a waitlist.ClassKeep tries to remove that end-to-end:- Public booking page on a free *.classkeep.app slug (custom domain optional), with a drag-and-drop page builder so it doesn't look like a generic SaaS template. - Credits, drop-ins, and recurring subscription plans, all via Stripe Connect — the studio gets paid directly, I never touch the money. - A waitlist that auto-notifies via email + web push + SMS the instant a seat opens; first tap wins. This is the part most studios told me they'd pay for on its own. - 1-tap tablet check-in for instructors so they're not fumbling with a
