Show HN: AuraSpend " Voice-first expense tracker using Gemini for NLU

Hacker News - Sat, 02/14/2026 - 1:30pm

I built an expense tracker where the primary input is voice. The thesis: expense tracking apps fail because manual entry has too much friction, which is why most people abandon them within weeks.

How it works: - Open app, tap mic - Say "yesterday I spent 30 dollars on lunch at Chipotle" - AI extracts: amount, merchant, category, date - One tap to confirm and save

Other features: - Receipt scanning with ML Kit OCR + Gemini Vision for parsing - Background notification listener that catches bank alerts and creates pending entries - GPS-based currency detection for travelers - Multi-language with native script fonts (Nastaliq for Urdu, Devanagari for Hindi, Amiri for Arabic) - Offline-first with Google Drive sync

Tech: Flutter, Riverpod, Hive, Gemini 2.0 Flash

The hardest part was prompt engineering for consistent JSON output across languages. Had to build "Supreme Laws" into the system prompt - things like "never translate native text" and "extract currency from context."

Free tier available. First 500 users get Pro free for a year.

Play Store: AuraSpend

Happy to discuss architecture, prompt engineering approach, or take technical feedback.

Show HN: Aurora-OS.js – High fidelity hacking simulator pre-alpha

Hacker News - Sat, 02/14/2026 - 1:06pm

Extensible web OS game and hacking simulator framework for developers and gamers. Virtual OS experience with scripting, apps, terminals & sandboxed gameplay, set in the mental.os() universe.

Born from the intersection of digital art and cyberpunk culture, this project reimagines the operating system as an immersive game world. It is a high-fidelity hacking simulator built on modern web technologies (React, Vite, Electron), designed to blur the line between utility and gameplay.

Currently in its pre-Alpha stage, it serves as the foundation for a future MMO hacking universe - a persistent world where you script, hack, and uncover the lore of an emerging game universe.

Contributors & testers wanted!

Show HN: Describe your Discord server in one sentence – AI builds it in 60s

Hacker News - Sat, 02/14/2026 - 12:56pm

We kept seeing the same problem: someone wants a Discord server for their community, game group, or project - and then spends hours setting up channels, roles, permissions, bot configs. Most give up halfway and end up with a half-broken server.

So we built an AI agent that does the entire thing. You type something like "competitive gaming community with tournament brackets and rank progression" and 60 seconds later you have a fully configured server with 30+ channels, roles, permissions, welcome system, moderation, tickets - everything working. It's not a template picker. The agent actually reasons about what your community needs - a music production server gets different channels and permissions than a study group or a startup team. What surprised us: people don't just use it once. They keep coming back to spin up servers for new projects, events, or clients. One user runs 5 servers through it now. The white-label tier lets you run it all under your own bot name and branding, which turned out to be the feature nobody asked for but everyone wants once they see it. Free to try - no credit card needed.

Secure Port Forwarding Without Exposing Internal Services

Hacker News - Sat, 02/14/2026 - 12:54pm

Port forwarding is often the fastest way to access an internal service — a database, admin panel, or metrics endpoint.

But in many setups, that means opening a public port and relying on firewall rules or IP restrictions for safety. Those rules tend to accumulate over time.

I’ve been looking at how modern “brokered” port forwarding models work. Instead of exposing a service publicly, they rely on outbound-only connections and create identity-scoped tunnels that exist only for the duration of a session.

No persistent inbound ports. No long-lived firewall exceptions.

I wrote a breakdown here, focusing on mechanics rather than product pitch:

Curious how others here handle temporary service access in cloud environments.
