Note taking apps that work with stylus

Hi everybody, recently I've been fascinating by all this open source world and I'm trying to switch from the big company apps to these type of apps, I'd rather have something that is completely local on my PC, light, and that works well with a Lenovo Pen, 'cause I use it a lot for note taking at university.

Traceprompt - open-source SDK for tamper-proof LLM audit trails

Hi!

I’m Paul, founder of Traceprompt. We’re building an open-source SDK that wraps your LLM calls and generates tamper-proof audit trails, so you can prove who did what, when and with which model.

You can check out the Node SDK (more languages coming soon): https://github.com/traceprompt/traceprompt-node

We built Traceprompt because LLMs are being used everywhere without a clear plan for audit and compliance. From research and discussions with other devs, I often see fintech and healthcare teams manually stitching together API Gateway, CloudWatch Logs and S3 buckets to track prompts/responses and retention. This is both complex and costly as there's little to no proof of immutability. Most current tools (Langfuse, Heliclone etc.) focus on LLM observability; few help generate verifiable evidence for compliance. That’s where we come in.

To add, regulations are also moving in this direction (e.g. the EU AI Act requires logging for certain high-risk systems, HIPAA calls for audit controls and FINRA/SEC rules push WORM-style retention). The goal is to make “prove nothing changed” boring.

Our SDK is simple:

1. BYOK architecture with AWS KMS. We never see plaintext prompts/responses; only you can decrypt. Other KMS providers are on the roadmap.
2. Append-only, hash-chained logs with a public Merkle anchor for independent verification. Repo: https://github.com/traceprompt/open-anchors
3. Audit packs: export CSV rows + proofs (and receipts) when someone asks “what exactly happened on this day and time.” You can also verify the audit packs — if a single byte was altered or a row removed by a bad actor, verification fails.

If "AI audit trails" are on your mind or on your roadmap, I'd love to talk. Please do checkout the repos: review code, install the SDK and experiment; open issues if anything breaks

1. https://github.com/traceprompt/traceprompt-node
2. https://github.com/traceprompt/open-anchors

We'd love to hear your feedback, so we'll be in the comments! If you're a dev, I am happy to dive into more technical details or answer any questions. If you're in the AI audit and compliance space, please do get in touch as we have lots to learn and uncover :)

Thank you!

Looking to help test

I want to be completely transparent in saying I did recently graduate a boot camp and with that being said I’m looking for open source projects that preferably have a couple testers helping already, my goal is to both gain experience testing fully on my own but also collaborating with others as I don’t have much experience making full test suites myself.

16 y/o team here – we open-sourced our AI project after 10 months of work. How do you grow a community?

Hey all,
We’re a small group of teenagers from Turkey who spent the last 10 months coding an AI app in our free time. We open-sourced it under Apache 2.0 because we wanted to share and learn with the community.

We’ve just started sharing it around, but we’d really love advice: how do early open-source projects attract contributors and keep momentum? Any tips from your own experience would mean a lot.

BuckleVibes: Convert Your Favorite MechVibes Soundpacks to Bucklespring

If you've ever used MechVibes, you've probably noticed it can have some pain points, like input delay. I've found that bucklespring is much more responsive, but it's limited to just one sound.

BuckleVibes is a simple Python noscript that takes a MechVibes V1 soundpack and automatically converts it into a folder of individual .wav files, ready to be used by bucklespring.

The project is available on GitHub: https://github.com/p-febis/bucklevibes

You'll find installation instructions and usage examples in the README. You'll need Python and FFmpeg installed.

I'd love for you to try it out and let me know what you think! Feedback, bug reports, etc. are welcome.

Any open source MMO or other projects looking for volunteer GMs or community support?

Hey all,

I’ve recently started volunteering with ChromieCraft (a World of Warcraft Wrath project) and I’m really enjoying helping with community support, bug triaging, and suggestions. It got me thinking:

Are there other open source MMO style projects (or game servers) that are looking for beginner friendly volunteers?

I’m especially interested in roles like:

GM / player support
Community moderation
Testing / bug triaging
Writing guides or doing outreach

I know about projects like ChromieCraft, WorldForge, and Multiverse, but I’d love to hear if anyone here knows other communities that welcome new contributors.

Thanks in advance!

🎯 I built tools I needed — now I'm sharing with all

Hey folks,

Over the last few months, I found myself constantly pausing to solve the same annoying problems while coding — the kind of things that slow you down but never feel big enough to warrant a full-blown tool. So... I built them. And now I’m sharing them for free, in case they help you too.

1. 🖼 vscode-screenshotify

Ever needed to share a clean snippet of code on Twitter or in docs?

I was tired of switching to Carbon or clunky browser extensions, so I made this extension right inside VS Code.

One click → beautiful screenshot of your code. Zero config, super light.


2. 🔄 dhara

I find it super frustrating that in 2025 I need to juggle btwn different techniques just to send files to my pc to phone or from phone to desktop. Either mail, or telegram or any other 3rd-party site that stores your file to their cloud.

Hence, I made a CLI tool that solves this with just quick QR code scan you can send, recieve with just a command. Modern solution for Modern folks.


And because I apparently hate free time, I’ve started building something new:

3. 🔥 An open-source heatmap CDN for frontend devs
It’ll be a plug-and-play noscript you drop into your HTML. No tracking creepiness, no selling data. Just a lightweight way to see where users are clicking and how they’re interacting with your frontend — perfect for indie devs or small teams without $$$ for Hotjar.




---

These projects are totally open source, no paid tiers, no BS. I'm just a dev scratching my own itch and hoping it helps others too. If any of this sounds useful, I’d love feedback, PRs, or ideas!


Let me know if you’d use the heatmap tool — trying to gauge whether to open that up early 🙌

Cheers!

After trying 15 productivity apps, I built my own (open-source)

I love productivity tools, but after years of trying Google Calendar, Todoist, Evernote, Notion, Trello, TickTick… none fully worked for me.



So I built my own open-source project:

Three item types: notes, tasks, folders – all in one place

Flexible hierarchy: folders within folders, drag-and-drop, undo/redo

Natural RTL + LTR text support (auto-detected per line)

Cross-device reminders + fast sync

Rich text editor with secure image uploads, multilingual search



It’s not “the next big app,” just something that solved my pain points — and maybe it can help others too.

The repo is public, and I keep a roadmap of future features (\~45 planned).

Would love feedback from other makers: what’s the best way to grow an open-source productivity project?

Open source cellular concrete mixer.

We could use some help. I've been going on this for 14 months. I'm self funded. The only thing likely to give us trouble is the transfer pump arrangement. https://www.reddit.com/r/OpenSourceAircrete/

If this looks like something you would like to be involved with, we need a technical writer.We've written 120 pages of research about residential cellular concrete techniques. You would be proofreading final drafts for syntax mainly. We also need someone who understands materials science to save us time on pump design (have to avoid shear in the material). I have project money to pay for qualified help. We need graphic design help too.

Building an open-source Bitcoin vault with time-delays & recovery — looking for beta testers

Hey everyone 👋

We’re developing an open-source Bitcoin Vault that aims to solve a long-standing problem: how to keep funds safe not only from online hacks but also from real-world coercion.

The design combines:

2-of-3 multisig as the default spending path
Time-delayed transactions (2h–15d), enforced on-chain, so the owner has a reaction window
A trustless recovery path after 1 year, even if co-signers disappear
Support for QR-based hardware wallets (SeedSigner, Passport, Keystone, Jade)

Right now, the full code isn’t public yet — we’re still going through security reviews. But we’re opening up a free beta test to get feedback on usability, UX, and design choices before the wider release.

👉 If you’d like to try it out, you can leave your email at https://bitvault.sv to join the beta.

This will always remain an open-source project, and early testers will help shape how it evolves. Any thoughts, critiques, or ideas from the open-source community are very welcome 🙏
