Show HN: Mnemify – 3D terrain map merging Confluence, Notion, Obsidian

Hacker News - Wed, 10/14/2026 - 6:36am

I have been working on documents for last 5 years. Recently I realized I was using Confluence to structure execution notes, Notion for thoughts during meetings, Obsidian for quick local notes, and then reading back notes from Googles note taking apps. My colleague had the exact same problem. We had MCP connected to Claude, but there was no way to bring all of that into one place that was intuitive. So we built Mnemify. Which converted all our notes from every app to a 3D traversable terrain instead. We’ve been using it daily for last two months and found it useful so decided to share it.

What it does: it harvests your sources into a local folder, then using your AI subscriptions compiles them into a 3D terrain you can traverse. Regions and peaks come from context, so related things end up adjacent from all your connected apps.

We also have chat over the compiled graph that cites the exact source passages.

You can also view time wise how the terrain was modified over time and see all your note higlights and action items in workspaces.

Everything stays on your machine. It never writes back to any source. Models are bring your own: OpenAI, Claude (your claude CLI or a subscription), or a fully offline mode with an on-device embedding model.

Currently supported sources: Confluence, Notion, Obsidian and local files. Jira, Linear, Slack, Gmail and Google Meet notes are built and coming...

Please try it out, would appreciate your feedback.

Show HN: Building an LLM from Scratch in TypeScript

Hacker News - Wed, 10/14/2026 - 6:29am

I wanted to understand transformers at a level where nothing is magic, so I'm building a ChatGPT-style model from first principles in TypeScript. Why not Python? I've found that reimplementing concepts in a different language forces me to grasp the nuance of the implementation. Chapters cover dataloaders, embeddings, and the attention mechanism so far. Feedback welcome if anything's unclear.
