Linggen
The engine for AI-native apps — local, open-source, on Mac
Linggen is an open-source Mac app that runs AI apps locally. The lead app is a private CFO: drop in bank/card CSV or PDF exports and local code turns them into spend reports — trends, subscriptions, duplicate charges — with account numbers redacted before any AI sees them. Also inside: a music DJ with karaoke, a Mac health scanner, and cross-agent memory shared with Claude Code and Codex. Apps are markdown + HTML/JS on a Rust runtime. BYO model (OpenAI-compatible or Ollama) or free hosted tier.
Hi Product Hunt! I'm Leon, solo builder of Linggen.
I think the most useful AI apps won't live in the cloud — they'll run on your own machine, next to your own files, music, and finances. Linggen is my attempt at that: an open-source runtime (Rust daemon, Apache-2.0) that runs AI apps locally on your Mac. Apps are just markdown + plain HTML/JS — no build step, so you can read every line of what an app does before trusting it.
It ships with five apps:
• CFO — drop in bank/card CSV or PDF exports; local code parses them into spend reports (trends, subscriptions, duplicate charges), and account numbers are stripped before any AI sees a thing. The AI only explains — "why was May so expensive?"
• DJ — tell it a vibe, it builds the tracklist, grabs the audio, and syncs to your phone for offline play. Karaoke included.
• Sys Doctor — scans your Mac's health (disk, security, performance) and explains what it finds in plain language.
• Pulse — a personal trends radar for the topics and feeds you care about.
• Memory — cross-agent semantic memory that also works from Claude Code and Codex.
Bring your own model (any OpenAI-compatible endpoint or Ollama) or use the free hosted tier — no key setup.
Two things I'd love your take on: which of these would you actually use first? And what would it take for you to trust a local app with something as sensitive as your bank statements?
Local-only finance tracking with redaction before any model touches the data is exactly the kind of setup I want. One thing I'd love is a built-in budget alert system that can ping me when a category crosses a threshold I set, since right now I only get insights when I open the app and run a report.
Really cool idea, especially the redaction before any model sees the data. One thing I'd love: automatic scheduled imports from my bank or card accounts instead of having to drop in CSVs by hand. Even a simple watch folder or Plaid integration would make this a set-and-forget weekly review rather than a manual chore.
