Gauth Unlimited Digital Canvas

468

Gauth AI Course now runs on an Unlimited Digital Canvas: one continuous whiteboard where lessons unfold spatially instead of in a chat thread or slide deck. Chapters expand side by side as narration plays, board notes write out in sync with the AI voice, and you can zoom from the full concept map down to a single formula. Pause anytime to ask the AI Tutor, and it answers right on the board beneath your step. Generate a canvas lesson on any topic, then export it as a PDF or share a link.

HN.watch – Videos of all Hacker News posts

224 pts

Hi HN, I’m Per, founder of Scrimba (YC S20). We’ve spent the last decade teaching people how to code with an HTML-based video format. We’ve now plugged an LLM into it, so that people can create explainer videos about anything. It’s called “Scrimba Explain”. To demo this technology for Hacker News, we built HN.watch. It’s like HN, but with explainer videos instead of articles. We create them on-the-fly the first time someone clicks on a link. While there are obvious visual drawbacks of using HTML...

Breadcrumb, record everything on your mac + context manager for AI

46 pts

Hi HN, I'm Justin. Breadcrumb records everything you do on your Mac (screen + meetings + AI transcripts + what you and your AI decided) and turns it into memory your AI can search. It's local and encrypted. You can also teach it rules by talking to it and it makes sure the right rules turn up in the right context. Works with Claude Code / Codex / Cursor / opencode. All of this is exposed to your AI as 30+ MCP tools (here's the definitions): https://innerloop.works/breadcrumb/mcp I started it in... (46 points, 8 comments).

OpenAPPA – open-source deterministic guardrails that don't break agents

25 pts

Hi Hacker News! Matvey, one of the authors, is here. While building enterprise agents, we ran into a problem: the more tools you connect to the AI, the higher the chance it will run out of control and leak sensitive data. Guardrails, in theory, should prevent this, but the situation is worrying: - Non-deterministic guardrails (LLM as a judge, auto modes, etc.) are vulnerable to prompt injections, or they lack knowledge of the data, making them inefficient (~10% data leaks on our benchmarks). - E...

Strata – an expressive semantic layer that can say no to your LLM

23 pts

Hello HN, I'm Ajo and I built Strata. I spent 4 years at Netflix solving self service for non-technical business users. I think I cracked it with my unique approach to semantic layer design. The key challenge is balancing expressiveness with ease of use for our non technical colleagues. It just so happens that focus made it work pretty well with LLMs too. Strata is a full stack solution. It includes a semantic layer, dashboards, subscriptions, and google sheets exports. All of it can be done vie... (23 points, 15 comments).

PlaceCall (YC W26) – agentic API to call businesses and get things done

16 pts

Hi HN, this is Yarik and Vlad from VOYGR - we are building the tools for agents and apps to engage with local businesses. It all started with our own pain point at VOYGR: calling businesses to verify if they are open. We are both from Google (Maps and Search) and even there, the merchants and venues don’t keep this info updated. So we built an API and started using it in-house. On July 4th, we were driving through Portland looking for a place to eat. Google Maps was saying “Holiday hours may var... (16 points, 4 comments).

Made an open-source Lego AI generator

134 pts

Hi there :-) New on HN, first time posting. Past year, around December, I started experimenting with making ChatGPT and Claude generate source code in LDraw language. This LDraw is literally an "assembly" language, a low-level programming language that describes how to assemble LEGO pieces together into models, one placement instruction at a time. When executed by specific tools, like e.g. LDView, LeoCAD, Studio... these instructions become LEGO CAD models, that can be interacted with, modified,... (134 points, 49 comments).

Viggle Turbo for Qwen-Image-2.1

168 likes

6-step Qwen-Image-2.1, T2I + editing, vs-base comparison Viggle Turbo v0.3 — 6-step Qwen-Image-2.1 A distilled Qwen-Image-2.1 that generates and edits images in 6 steps with no classifier-free guidance, about 5× faster than the 40-step base model. On most prompts it is hard to tell apart from the base model; small, dense text and complicated edits (multi-reference composition, face swaps, identity-preserving edits) can still fall short of it. v0.3 (2026-09-29): at 6 steps, less grain than v0.2.1 and a little softer on fine texture. We think 6 steps is close to its capacity: every further gain we found cost something elsewhere. The new 9-step setting runs 7 turbo steps and lets the base model...

Just a fruit fly's brain, playing chess Play chess against the complete connectome of an adult fruit fly. The FlyWire brain (138,639 neurons, 15.1M connections) runs in your browser on WebGPU: the board drives its 10,855 visual sensory neurons, activity settles over 5 steps across the whole graph, and the central brain and descending neurons are read out into a move and a win probability. Every forward pass lights up the 3D brain as it happens. The brain and the weights are about 150 MB, downloaded once and then cached. The wiring is fixed, exactly as the reconstruction has it, signs included. Only the encoder, the strength of each connection, each neuron's homeostatic gain and threshold, an...
