Show HN: Mumble Dictation – local dictation that learns your vocabulary
Hey HN! It’s Wen from Narya.ai. We build Mumble Dictation, a local-first and privacy-focused dictation app on Mac.
Homepage and Download: https://heymumble.com/dictation
YouTube:https://youtu.be/Bma59TrR62c?si=DM-LyjZY5GZ9-f64
Two things kept bugging us about the dictation products on the market:
1. Most of them ship your audio to the cloud, and those who is claiming to be private are often just a thin wrapper of cloud APIs with a privacy policy.
2. Those general-purpose ASR models are terrible at your vocabulary: library names, co-workers' names, project codenames, etc.
Mumble Dictation is built around those problems. Its full pipeline including ASR and transcript cleanup is running on your device with local models. Your audio never leaves your machine. Plus, it collects the hot words in your daily usage and gets them spelled correctly.
In particular, the app learns from what you type and what's on your screen, entirely locally, and builds a personal dictionary. At inference time, we boost those terms during decoding, so "Supabase", "PowerSync", or your teammate's name comes out right the first time, instead of some phonetic guess. The dictionary never leaves your machine for sure.
A few other things it does:
- Multilingual (40 languages)
- Custom transcript transform (concise, bullet points, translate, or any prompt you can define yourself)
- Bring your own API key (OpenAI, Anthropic, Ollama, etc.) if you want a different LLM model for transcript cleanup
- Voice shortcuts: say "buy paper towels" and it opens Amazon with the search filled in, or "ask Claude about dictation apps" and it opens Claude with your question already submitted
Pricing is a one-time purchase, no subscription. It's $50 at launch (half the planned price).
Happy to answer questions here.

Show HN: Bookshelf – book quotes that appear between Claude Code and Codex turns
This is a small quality of life project i built for myself and using it for 3+ months now, decided to fork it out and publish as a skill separately.
Instead of seeing terminals filled with code and tool calls, seeing a book quote felt like a breath of fresh air considering all of us are glued to it day and night.
Hope the random quotes that pop up in your terminals lets you have a moment of pause or happiness every now and then while the agents keep churning out stuff for us.
Please feel free to give it a spin and let me know your thoughts and feedback!

Show HN: Skim – a minimalist open-source email client for Windows (MIT)
I built Skim because I was super dissatisfied with all existing Windows clients.
I mean, it's not a rocket science, there should be some lightweight modern solution, isn't it? So I decided to create a client that just, you know, MAKES SENSE and has design younger than dinosaurs.
Key points:
* Obsessed with installer size: it should be under 5Mb.
* BYOK AI. Cowriter, agentic search, summarization and other AI stuff is powered by your own key for Anthropic/Openrouter, or you can connect your own OpenAI-compatible server (including local)
* No bloat. It should be as contextual as possible: gives you right button when you need it. No menu at all. No integrations. Just email.
* Instant startup, super modest on resources
* Cool warm zine design with paper colors and really calming vibes
It's MIT - contribution and stars are welcome!
