## The Shed — experiments and demos

- [When Voice AI Meets the Suburbs](https://biswa.info/the-shed/voice-ai-suburbs/): VoiceAI is hard - a bot can transcribe "Geelong" easily, or could mis-spell it to "Jlong" (based on how it's pronounced by locals).  High accuracy in specific domains (medicine, suburbs, aviation) is the hard part. This is a field note on the gap in between. [tags: ai, voice, python]
- [AI Generated Invoice Validator](https://biswa.info/the-shed/invoice-validator/): Upload a PDF invoice; a vision LLM extracts its structure, a second synthesises a bespoke validator on the fly, and that code executes in a sandboxed runtime with no network access. Cached after two stable runs. Streamed live. [tags: ai, agentic workflow]
- [Mastermind](https://biswa.info/the-shed/mastermind/): A classic logic game implemented in ScalaJS. Can you crack the code? [tags: game, scalajs, logic]
