Show HN: Swalpa – Spoken Kannada learning platform built with Antigravity

Hi HN,

I built SWALPA (https://swalpa.org) because learning spoken Kannada is a New Year's resolution for me and I realized most language apps teach you formal grammar, but not how to negotiate with an auto-rickshaw driver or handle the "daily chaos" of the city.

THE AGENTIC STACK (BUILT WITH ANTIGRAVITY)

I wanted to see how far I could push a "Human-in-the-loop" AI workflow to create high-quality content in a low-resource language.

* The Coder: Antigravity (an agentic coding AI) handled the heavy lifting—writing the JS game engines and drafting the core lessons based on a custom "grammar spec."

* The Knowledge Base: I used Gemini Deep Research to build a high-fidelity reference of Kannada linguistics. This acted as the "Source of Truth" to prevent AI hallucinations.

* The Content Engine: I fed my core curated lessons into NotebookLM to generate supplemental podcasts, slides, and flashcards to boost recall.

* Architecture: Simple and Boring—Static site (MkDocs Material) + Vanilla JS + Firebase.

THE EXPERIENCE

Instead of "The cat is on the table," SWALPA uses interactive games to simulate real-world Bangalore scenarios:

* The Auto-Rickshaw Negotiator: Use the right phrases under timer pressure to get the driver to use the meter ("Meter Haaki!").

* Rapid Translation: A high-pressure mode where you hear a Kannada phrase and must pick the correct translation from four options under a timer.

* Agglutination Mastery: Interactive drills for Kannada's unique word-stacking grammar.

The platform includes 10 core text lessons and Duolingo-style gamification—including badges, streaks, and an activity heatmap.

I am a Software Engineer at Google, but this is a personal passion project. I would love to hear your thoughts on the AI workflow or the "street-smart" approach to language learning!
