Tsarpon Ask HN: What are you working on? (July 2025)

Fastest locally running dictation tool for developers. Done with VAD, noise profiling, low level audio work.

Tsarpon Show HN: Typeform was too expensive so I built my own forms

I recently had to do a form and just asked claude to 1. Write up the form with the questions styled with tailwind, shadcn, heroui. 2. Wire it up and give me a cloudflare function to write to a KV store 3. Instructions on how to setup above with cloudflare free tier.

It got it in the first shot, took me <3-4mins to copy paste in cloudflare. Been working well so far, the page is also hosted on cloudflare pages and hasnt cost anything so far.

Tsarpon Ask HN: Any resources for finding non-smart appliances?

Someone should build a search listing for this.

Tsarpon OpenFLOW – Quickly make beautiful infrastructure diagrams local to your machine

I had the same issue. I found this and it works decently well and OSS.

Tsarpon Ask HN: What Are You Working On? (June 2025)

Im just stuffing the binary into a scratch container. I had to port over openssl certs, but works like a charm after!

Locally running wispr flow equivalent without any tracking, signup, analytics or subscriptions.

Dictate into any text window on your Mac. Works really well with technical language specifically when using with claude code, cursor, windsurf.

Very fast since the underlying whisper.cpp lib is very well optimized for Metal and CoreML usage on Apple Silicon machines.

Low friction Markdown based voice journaling. Locally transcribed voice memos with whisper and write as markdown files (to any folder or obsidian vault).

Tsarpon Ask HN: What Are You Working On? (June 2025)

https://github.com/srv1n/kurpod

Lets you create encrypted containers disguised as normal files. 1000s of images, pdfs, videos, secrets, keys all stuffed into an innocent look "Vacation_Summer_2024.mp4".

I've almost got true steganography working i.e to get the carrier file to actually open in any file system(currently with mp4, pdf, png and jpeg).

Things like this have existed in the past, but nothing with a simple UI,recent encryption standards.

Tsarpon Show HN: Nxtscape – an open-source agentic browser

Dont you need to navigator.webdriver === true for CDP to drive automation? Maybe I need to update my understanding on this. THis is usually a dead giveaway

Tsarpon Show HN: Nxtscape – an open-source agentic browser

True, but its orders of magnitude lesser when webdriver flag is an extremely basic bot check that is now considered 101.

Tsarpon Show HN: Nxtscape – an open-source agentic browser

With stuff like https://www.cloudflare.com/en-in/application-services/produc... and https://blog.cloudflare.com/ai-labyrinth/ big money going on both sides last thing you want is to shadow detected as a bot. Its all ok if you are scraping to top rated SEO slop which is usually static sites but for anything beyond it wont work well eventually. Quite a few issues on browerbase, crawl4ai and similar repos around being detected as a bot.

Tsarpon Show HN: Nxtscape – an open-source agentic browser

CDP is great for testing. But one of the most basic checks for bot detection is checking for CDP(webdriver). Its always going to be a cat and mouse game. You'll see a bunch of solutions captch solvers etc, But they usually are only good for a few weeks.

Tsarpon Show HN: Nxtscape – an open-source agentic browser

Why not something like https://github.com/nanobrowser/nanobrowser.

Its kinda built really well without exposing webdriver etc and can comfortably run js and communicate with LLMs.Has full agentic capabilites.

Why a new browser instead of a robust extension?

Tsarpon Harper – an open-source alternative to Grammarly

I was initially impressed. But then I tested a bunch, it wasn't catching some really basic things. Mostly hit or miss.

Tsarpon Ask HN: What API or software are people using for transcription?

huh! nice!

Tsarpon Ask HN: What API or software are people using for transcription?

Runs locally on device. So no server costs.

Tsarpon Ask HN: What API or software are people using for transcription?

I'd love for you to try https://carelesswhisper.app

- Locally running, wrapper around whisper.cpp

- I've done a lot of work on noise profiling, stitching the segments. So when you are speaking for anything >2-3mins, its actually faster than cloud transcriptions. (Accuracy is a few WER off since they are quantized models).

- You can try without paying or putting in CC. After that ~19$ one time. No need to sign up or login.

- BYOK to use your groq, gemini free daily credits to rewrite. Support for thinking models too. can also plug into any locally running LLM.

- Works on my 1st gen M1 without a sweat.

Tsarpon Ask HN: Options for One-Handed Typing

Maybe worth considering speech to text. Dictation has come a long way and if they are using a Mac any of the locally running whisper wrappers will work.

1. https://goodsnooze.gumroad.com/l/macwhisper (dictation + transcription)

2. https://carelesswhisper.app (does dictation only, and does it really well; cheapest)

3. https://superwhisper.com (both local and hosted models + lots of bells and whistles, but much higher pricing)

Tsarpon Microsandbox: Virtual Machines that feel and perform like containers

Great will join the discord. Is this embeddable? Will it work with a cross platform desktop app(Tauri)?

Tsarpon Microsandbox: Virtual Machines that feel and perform like containers

Wow. This looks awesome.

Can we build our own python sandbox using the sandboxfile spec? This is if I want to add my own packages. Would this be just having my own requirements file here - https://github.com/microsandbox/microsandbox/blob/main/MSB_V...

Tsarpon Ask HN: What are you working on? (May 2025)

A local dictation app for Mac to use when coding. I spend a lot of time talking to Cursor, Chatgpt and needed to get rust and swift library names correctly.

Spent a lot of time on low level hardware libs to roll out my own version of VAD, grammar correction and stitching segments.

Faster than the hosted dictations tools thought it runs locally and a lot more control in terms of custom vocabulary.

Tsarpon Ask HN: What are you working on? (May 2025)

Building a small framework for securely connecting desktop apps/clis directly to your existing browser using Native Messaging i.e no headless browsers or cloud sandboxes/proxies involved.

Inspired by secure password managers like Bitwarden, goal is to reduce detectability, avoid CAPTCHAs, and mitigate common fingerprinting pitfalls.

The idea is simple: leverage the trust your browser already has.

Tsarpon Ask HN: What are you working on? (May 2025)

Looks neat. Have you thought of GTM? Is it B2C or are you thinking enterprise.

Tsarpon Ask HN: What are you working on? (May 2025)

Looks neat. How does it compare to the already available solutions out there/any thing different about it?

Tsarpon Show HN: Defuddle, an HTML-to-Markdown alternative to Readability

Been using the obsidian clipper since it was out and this is a really neat. The per website profile based extraction is awesome.

Even if you are not a obsidian user, the markdown extraction quality is the most reliable Ive seen.

Tsarpon I have tinnitus. I don't recommend it

Very interesting, I started noticing it around the whole covid time too. Somehow I associated it with excess headphone use from WFH, combined with lesser general mobility(bed to desk commute).

Tsarpon Game theory illustrated by an animated cartoon game

This is really the best ways to explain basic game theory to anyone. It wasn't until some excellent Profs in Grad school that I finally understand some of the most basic concepts, but would always find it hard to explain to friends and family.

I also think game theory is one of the most important philosophies/life-lessons to understand as you go through life and this is an excellent resource to get people started on the basics.

Tsarpon Claude Code SDK

Voice as an interface is a life changer if you've ever had any bit of RSI at any point.

Tsarpon Claude Code SDK

Probably worth trying one of the many dictation apps out there based on whisper. They can get most coding terms(lib names, tech stack names) accurately and its one of those things you have to really try for a week before dismissing fully.
