Show HN: I read Replika's privacy policy and then built a competitorhttps://apps.apple.com/us/app/friend-ai-private-chat/id6761649790I'm genuinely surprised at what people are willing to share with AI companions. Read Replika's privacy policy. Then Character.AI's. These apps store your most personal conversations on their servers, linked to your email address. A breach or subpoena and your identity is attached to everything you ever told your "AI friend." Eek.The only thing I think actually solves this is local inference. I remember browing r/LocalLLaMA and years ago and thinking this is the future. Local models are finally good enough. I was playing with the bonsai 8B 1-bit quant model a few weeks back and I think we're almost there. I built friendAI to see if there's market demand for local inference. Everything runs on your phone.What's actually on-device:- Bonsai-8B (1-bit quantized Qwen3-8B, ~1.3GB) via MLX for speed - Gemma 4 E2B (~4.5GB, GGUF) via llama.cpp for vision - A unified client that routes between themA few things I'm reasonably proud of solving in about a week:- Turns out the hardest part was actualApr 26, 2026 10:09 PM

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-eApr 25, 2026 8:53 AM

Show HN: I built a toy that plays grandma's stories when my daughter hugs ithttps://www.storyfriend.co.uk/This was a project I built for my daughter's first birthday present.For context, I'm a surgical resident in the UK by background and am currently taking a year out of training to study a masters in computer science. My daughter just turned one. There are two things she really loves: the first is particular soft toy that she just can't live without, and the other is a good story book.Her grandparents live hours away and I didn't want her to forget what they sound like between visits. I wanted her to hear them whenever she missed them.My parents brought my brother and I up with incredible stories and books from all sorts of cultures, many of the stories being passed down from their parents before them. I didn't want my daughter to miss out on that.Finally, I was sick of missing storytime with her when I had to leave for night shifts. I wanted her to hear my voice before she slept every night.For all these reasons, I decided to build Storyfriend. It's her favourite soft toy with a custom Apr 24, 2026 12:06 AM

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.

BendersLib: A Benders Decomposition Library in Pythonhttps://news.ycombinator.com/item?id=47870502BendersLib (https://benders.dev) is a Python library that supports a range of Benders decomposition variants, including Classical Benders Decomposition, Combinatorial Benders Decomposition, L-shaped Method, Integer L-shaped Method, Generalized Benders Decomposition, and Logic-based Benders Decomposition. While BendersLib provides built-in implementations of these methods, it is designed to be extensible. Users can implement custom Benders decomposition methods by customizing subproblem solvers and cut generators, and defining callback functions for enhancement strategies. BendersLib is solver agnostic and has built-in interfaces for popular Mathematical Programming and Constraint Programming solvers. Its support for rapid prototyping and high extensibility are designed to meet the needs of both researchers and practitioners in Operations Research and related fields.Apr 22, 2026 11:18 PM

Ask HN: Would you use revocable digital signatures to verify AI/Other content?https://news.ycombinator.com/item?id=47848539I’ve been exploring a potential product direction and wanted to sanity check it with people who actually build and ship things.Background: I’ve been working on a system using our core tech that can generate and verify digital signatures, but with a slightly different property than traditional approaches. The signatures are natively revocable. If the underlying model/system shouldn’t be trusted anymore, the signatures can be revoked either through a hard (delete the signing model) or soft (revoke the lease for the signing model) mechanism. I believe this feature is very beneficial on its own, but there are several other interesting properties (no key management, distributed verification, embedded metadata, etc.)Originally this came out of some deeper R&D work we’re doing, but I’ve been thinking this might actually be the most practical “wedge” into the market while we continue that research (and fund the research).One area that’s been interesting is applying this to AI systems.

This encourages care and consideration. - Nobody knows who you follow or what posts you react to, besides you and the other user. These stats are personal, so people view your logs free of outside influence. - Posts are rich text-only, no images or videos, in an effort to reduce mental clutter. - Your feed only features users you follow, to give you increased control of what you see, unless you click the "global" checkbox to see all posts.quick demo: https://www.youtube.com/watch?v=7CTnORsGnL8 overview page: https://www.weekly-log.com/about/overview---I have soft-launched this website, and a handful of my friends have signed up aApr 21, 2026 2:02 AM
