Hey HN! We love voice dictation, but wanted an open source version for transparency, privacy, and something that everyone could contribute to. So we built Voquill, an open source alternative to WisprFlow, Monologue, and SuperWhisper.

It lets you dictate into any desktop app. Press a hotkey, talk, text gets inserted. You can run Whisper locally, use our server, or wire up any provider you want (OpenAI, Claude, Groq, OpenRouter, whatever). You have full control over where your data goes.

Runs on Windows, MacOS, and Linux. Open source, AGPLv3, built with Tauri and Rust. We're working on a mobile app too (Flutter) that's currently in beta for iOS and android.

To try it: Download from the repo or voquill.com. Click "local setup" on first launch. Hope you like it!

Hey everyone, Nathan here: I'm an MLE at Mozilla.ai. I can't tell you how many things around my house I've been saying "I would really like to have somebody take a look at that". But here's the problem: all the people in the trades are extremely overwhelmed with work. There is a lot to be done and not enough people to do it.

One of my best friends runs his own general contracting business. He's extremely talented and wants to spend his time working on drywall, building staircases, and listening to Mumford and Sons while throwing paint onto a ceiling. But you know what gets in the way of that wonderful lifestyle that all us software engineers dream about?

ADMINISTRATION.

He thought running his own business would be 85% show up and do the work, but turns out a large chunk of the time is spent talking to clients to schedule time to get an estimate, working with home management companies to explain the details of an invoice, and generally just manage all of the information that he's gathering on a single day.

Luckily for the world, AI is here to help with this. Tech like openclaw has really opened our eyes to the possibilities, and tech to help out small businesses like these are now within reach.

That's why I'm excited to share out an initial idea we're trying out: clawbolt. It's a python based project that takes inspiration from the main features that make openclaw so powerful: SOUL.md, heartbeat proactive communication, memory management, and communication over channels like WhatsApp and iMessage. With clawbolt, we're working on integrating our latest work with any-llm and any-guardrail, to help make clawbolt secure and to ease onboarding.

This is all new, so this is a call for ideas, usage, and bug reports. Most of us that try to get plumbers/roofers/handymen to come help us with a home project know how overwhelmed they are with admin work when they're a small team. I'm hoping that we can make clawbolt into something that helps enable these people to focus on doing what they love and not on all the paperwork.

Let me know what you think! Docs at https://mozilla-ai.github.io/clawbolt/

My dad cuts window profiles in his workshop and I kept watching him measure, mark, and reposition by hand hundreds of times a day. So I built him a motorized ruler that moves to any position you tap on a tablet.

It runs on an ESP32-S3 over BLE 5.3, uses hardware-timed stepper pulses (RMT peripheral, no CPU jitter) to hit 0.5mm accuracy, and pairs with a Bosch GLM laser meter - point, measure, and the ruler moves there. No typing, no transcription errors.

You can also upload cut lists from a file or email and it runs each position in sequence - perfect for batch cutting window profiles where you need the same set of measurements repeated all day.

Open hardware: off-the-shelf linear rails, NEMA 23 closed-loop stepper, inductive homing sensor. Total BOM is about 470 EUR. I sell the firmware, app (Android + desktop), and a step-by-step build guide for 350 EUR.

Happy to answer questions about the build or the ESP32 RMT approach to stepper control.

I think everyone should build their own HN reader at least once in their life. This is mine and its pink. I wanted a good HN experience on mobile something I could pull up on the train and browse comfortably. So I built a PWA that works well on mobile and feels native on the phone. Along the way, I kept adding things: Semantic search – Stories are embedded with OpenAI's text-embedding-3-large and indexed in MongoDB 8.2's Vector Search. Search combines vector similarity and full-text via Reciprocal Rank Fusion, so you can find stories by meaning, not just keywords. Personalized feed: A profile vector is built from your reading history and bookmarks (weighted by time spent and recency). After a few stories, the feed adapts to your interests. Content extraction: A Playwright-based scraper fetches article text, generates thumbnails, and extracts metadata. Real-time updates and infinity scroll. Auth is passkey-first (WebAuthn) and works without personal information. Stack: Angular 21, FastAPI (Python 3.14), MongoDB 8.2, Valkey for job queues. It's a hobby project and I had a lot of fun building it. Feedback welcome!

In Hybrid Search, searchers such as BM25 and Vector Search run independently, produce separate result sets, and get merged...

Introducing ... ... Wormhole Vectors!

Instead of merging orthogonal results, traverse between the vector spaces. Run a lexical search, pool the matching documents' dense vectors, and search the dense space from that point.

Hybrid search runs two queries and hopes the right answer was in one of them. Wormhole vectors let you traverse between the spaces instead.
