Experiments at the edge of AI

Lars Jensen

A collection of things I have built while exploring what is possible with AI — small, honest experiments, each one a GitHub repository.

SpeechLLMLocal-first

Whisper Notes

A local-first voice journal that turns spoken thoughts into tidy markdown notes.

I wanted to see how far a fully local speech-to-text pipeline could go on a laptop — no cloud, no API keys. Whisper Notes records a voice memo, transcribes it with a quantised Whisper model, then asks a small local LLM to clean it up into structured markdown.

What it does

  • Records audio and transcribes it offline
  • Cleans filler words and punctuates automatically
  • Produces a short summary and a list of action items

What I learned

The transcription was the easy part — the interesting work was prompting a small model to reformat messy speech without inventing content.

RAGEmbeddingsSearch

Tiny RAG

A minimal retrieval-augmented chat over a folder of your own documents.

The smallest useful RAG I could build in a weekend. Point it at a folder, it embeds every document, and you can ask questions that are answered with citations back to the source passages.

What it does

  • Watches a folder and embeds new files automatically
  • Retrieves the most relevant chunks for each question
  • Always shows its sources so you can verify the answer

The goal was honesty: never answer without showing where it came from.

VisionMultimodalCreative

Pixel Poet

Drop in a photo and a vision model writes a short poem about what it sees.

A playful experiment in multimodal prompting. Pixel Poet looks at an image and writes a few lines of verse inspired by it — you can nudge the tone from austere to whimsical with a couple of dials.

What it does

  • Describes the mood and details of any image
  • Lets you steer style, length and tone
  • Keeps a small gallery of poems you liked
