Show HN: Mobile-ink, an open-source mobile infinite drawing canvashttps://github.com/mathnotes-app/mobile-inkHello everyone, I have been working on this for a year and it is such a difficult problem. mobile-ink is an open-source mobile infinite drawing canvas. There is not a strong open-source drawing engine beyond toy demos. Thus, mobile-ink aims to solve this problem and provide a state-of-the-art mobile note-taking canvas package.mobile-ink uses native Skia/Metal to address issues with native rendering, pencil latency, eraser behavior, page virtualization, preview caching, memory stability, page interactivity, etc. It has many advanced features such as shape-snapping, primitives to integrate figures, custom backgrounds, pdf import, stroke selection, smooth zoom/scroll, and more.The package is iOS + React Native as of now.

AniTroves – An anime database with a custom LLM-based discovery hubhttps://news.ycombinator.com/item?id=48057592I’ve always felt that traditional anime databases rely too heavily on rigid tag-based searches. If you’re looking for a specific "vibe" or a very niche trope that isn't a primary tag, you usually end up scrolling through pages of irrelevant results.I built AniTroves (https://anitroves.com) to experiment with a more conversational, LLM-driven approach to series discovery.The Tech Behind the Hub:LLM Integration: Instead of a generic API wrapper, I've been working on a custom hub (https://anitroves.com/ai-hub/) that uses specialized models to understand series lore and character archetypes for roleplay and discovery.Anipick Engine: This is the logic layer that maps natural language queries to our database entries.Technical Transparency: I’ve implemented a structured llms.txt (https://anitroves.com/llms.txt) to provide a machine-readable source of truth for other crawlers and AI models.I’m currently the technical administrator and I'm handling the SEO and server scaling (managed on Hosting

NASA Fosters Development of Lunar Resource-Seeking Technologieshttps://www.nasa.gov/technology/nasa-fosters-development-of-lunar-resource-seeking-technologies/To support long-duration missions to the Moon and Mars, NASA and industry are developing technologies that can extract resources such as hydrogen and helium-3 from lunar soil, known as regolith. This capability, known as in-situ resource utilization (ISRU), allows explorers to use what is already available on other planetary bodies, from water ice to minerals. […]

Nighttime Imaging Grows Landsat’s Science Valuehttps://science.nasa.gov/missions/landsat/nighttime-imaging-grows-landsats-science-value/By Earth Resources Observation and Science (EROS) Center For more than 50 years, Landsat has imaged Earth’s land and near-shore surfaces as the satellites descend in midmorning orbit, when daily sunlight is optimal. That’s just what they’ve always done. Currently, Landsat 8 and Landsat 9 circle the globe while also making better use of their ascending paths, […]

Show HN: A Karpathy-style LLM wiki your agents maintain (Markdown and Git)https://github.com/nex-crm/wuphfI shipped a wiki layer for AI agents that uses markdown + git as the source of truth, with a bleve (BM25) + SQLite index on top. No vector or graph db yet.It runs locally in ~/.wuphf/wiki/ and you can git clone it out if you want to take your knowledge with you.The shape is the one Karpathy has been circling for a while: an LLM-native knowledge substrate that agents both read from and write into, so context compounds across sessions rather than getting re-pasted every morning. Most implementations of that idea land on Postgres, pgvector, Neo4j, Kafka, and a dashboard.I wanted to go back to the basics and see how far markdown + git could go before I added anything heavier.What it does: -> Each agent gets a private notebook at agents/{slug}/notebook/.md, plus access to a shared team wiki at team/.-> Draft-to-wiki promotion flow. Notebook entries are reviewed (agent or human) and promoted to the canonical wiki with a back-link. A small state machine drives expiry and auto-archive.-> Per-e

Show HN: Core – open-source AI butler that clears your backlog without youhttps://www.getcore.me/Hi HN, we're Manik, Manoj and Harshith, and we're building CORE (https://github.com/RedPlanetHQ/core), an open source AI butler that acts and clears out your backlog.Write `[ ] Fix the search auth bug` in a scratchpad. Three minutes later, without you at the keyboard, CORE picks it up, pulls the relevant context from your codebase, drafts a plan in the task description, and spins up a Claude Code session in the background to do the work. You review the output in the task chat and unblock it when it gets stuck.Every AI tool today is reactive. You open a chat, brief the agent, it responds. Before anything moves, you've already done the real work: opened the Sentry error, found the commit, read the Slack thread, grabbed the Linear ticket, and stitched it all together into a prompt. The model isn't the bottleneck. You are.Demo Video: https://www.youtube.com/watch?v=PFk4RJvQg1YCORE removes you from that loop. The interface is a shared scratchpad, think a page you and a colleague both have o

Show HN: I built an app for comparing grocery prices across UK supermarketshttps://play.google.com/store/apps/details?id=com.wistfulcreations.GroceryCompare&hl=en_GBI'm a first year CS student at Sheffield and built this over the past year because I thought I could do better than Trolley.Stack: React Native & Typesense for vector search and filtering. An ETL pipeline runs in the background handling scraping and automatic product categorisation using embeddings.Covers Aldi, Tesco, Sainsbury's, Asda, Morrisons, Waitrose, Iceland, Ocado / M&S and Co-op. Clubcard and Nectar prices included. Sort by price per unit, filter by category and stores near you.This was fun to make, and I have a lot planned, with some WIP:- Basket Generation based on entering a shopping list and getting cheapest products for each store, and cheapest collection of stores for the cheapest total shop. Feels quite magical even in dev mode right now- Local price estimates. Local stores differ from online prices by up to 20% depending on store fascia. I'm thinking to record a basket of goods for each local store and use it to estimate local prices- Crowdsourced prices. Tricky one, d

Show HN: I built a $9 Ahrefs alternative because raw SEO data is cheaphttps://idiotproofseo.com/Like many solo devs and indie hackers, I was paying $100+/mo for enterprise SEO tools (Ahrefs, Semrush) but only using about 5% of their features. I really just needed basic keyword research, SERP difficulty analysis, and simple rank tracking.I wanted to see what the actual floor was for raw SEO data if you stripped away the fluff and enterprise bloat.I spent the last few months wiring together different data sources to find out. I got my costs down to a few cents per report and because the data is so cheap to fetch on-demand, I packaged it into a minimalist tool which strictly focuses on the essential elements of SEO:A keyword analyzer which pulls the top 10 search results, audits them, and flags weak spots (like low DA sites or forums like Reddit) to calculate a realistic difficulty score, a keyword finder which generates hundreds of scored long-tail variations, and a rank tracker with email notifications.Because the costs on my end are so lean, I don't need to charge $100/mo - so I

Show HN: Memv – Memory for AI Agentshttps://github.com/vstorm-co/memvmemv is an open-source Python library that gives AI agents persistent memory. Feed it conversations; it extracts knowledge.The extraction mechanism is predict-calibrate (Nemori paper): given existing knowledge, it predicts what a new conversation should contain, then extracts only what the prediction missed.v0.1.2 adds the production path: - PostgreSQL backend (pgvector for vectors, tsvector for text search, asyncpg pooling). Single db_url parameter — file path for SQLite, connection string for Postgres. - Embedding adapters: OpenAI, Voyage, Cohere, fastembed (local ONNX).Other things it does: - Bi-temporal validity: event time (when was the fact true) + transaction time (when did we learn it), following Graphiti's model. - Hybrid retrieval: vector similarity + BM25 merged with Reciprocal Rank Fusion. - Episode segmentation: groups messages before extraction. - Contradiction handling: new facts invalidate old ones, with full audit trail.Procedural memory (agents learning from past runs

Show HN: I made an AI that reviews iPhone apps – 1h of autonomous GUI workhttps://understudy-ai.github.io/understudy/I've been building Understudy, an open-source GUI agent for macOS. Wanted to push the GUI stuff beyond the usual short demos, so I tried turning it into an iPhone app reviewer.You give it one prompt. It browses the real App Store in Chrome, installs the app on a real iPhone through macOS iPhone Mirroring (not a simulator), opens the app and explores it — never seen Snapseed before — records clips and screenshots, composites a narrated review video with FFmpeg locally, uploads it to YouTube, then deletes the app. About an hour, didn't touch the keyboard.The exploration part is what I'm happiest with. The agent reads the App Store description, goes "they say background removal works, let me try that," and then figures out an unfamiliar app on its own. It regrounds from the live screenshot every action, so unexpected dialogs or UI changes don't kill it.The reason it can sustain an hour of work: each of the 6 stages runs as a separate child session with its own context. You can't fit an ho
