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 blind-tested 14 LLMs on a WP plugin task. Surprising Findingshttps://github.com/guilamu/llms-wordpress-plugin-benchmark/blob/main/README.mdRecently, GitHub Copilot silently dropped support for Claude Opus on Pro accounts. Since Opus was my go-to model for my daily workflow (developing WordPress plugins), I needed a reliable replacement.I decided to run a rigorous, blind benchmark across 14 state-of-the-art and local LLMs to objectively measure which model understands WordPress development best. To ensure a perfectly fair test, I started with a completely fresh IDE and zero context for every single generation.I asked each model to build a "Gravity Forms Live Search" plugin using a minimal, zero-shot prompt. To avoid personal bias, I had Gemini 3.1 Pro blindly grade the anonymized outputs against a strict 100-point rubric, comparing them to my own reference implementation.Surprising Findings1. The "Blind Spot" (Re-inventing the wheel) Out of 14 models, exactly 0 successfully hooked into the native Gravity Forms search input (#form_list_search).

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.

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

Show HN: BigBlueBam, MIT-licensed Work OS where agents are first-class coworkershttps://github.com/eoffermann/BigBlueBamHi HN, Eddie here. My project BigBlueBam is a self-hosted, MIT-licensed Work OS with a unified backend with native MCP, "AI as Users" rather than bolted-on chat widgets. The deploy script will stand up the full stack (local Docker container or push it to Railway) in about the time it takes to make coffee.What's live in the build: * Bam (project management/Kanban) * Banter (chat with LiveKit voice/video) * Beacon (knowledge base with a graph view) * Brief (collaborative docs) * Board (infinite canvas whiteboard) * Bolt (workflow automation) * Bearing (goals and OKRs) * Bond (CRM) * Blast (email campaigns) * Bench (analytics and dashboards) * Book (scheduling) * Blank (forms) * Bill (invoicing) * HelpdeskThe architectural bet I cared about most: MCP is the execution substrate for the whole suite, not a "feature". 340 MCP tools (and counting) registered across the apps.

Show HN: Reinhardt – Django-style Rust framework; WASM+SSR from one DSLhttps://github.com/kent8192/reinhardt-webReinhardt is a Rust web framework where one component DSL compiles to both WASM (client) and server-rendered HTML — a single file describes both sides of a page, with no separate frontend codebase, no JS build toolchain, and no duplicated types across the client/server boundary.It also bundles what Django/DRF users expect: an ORM with auto-generated migrations from #[model] macros, DI, auth, admin, REST, background tasks, and i18n. Feature flags let you pull in just what you need (minimal / standard / full), or import individual crates directly.I built it after moving from Django/DRF to Rust and repeatedly re-assembling the same Axum + ORM + migrations + auth stack for every project.Quickstart: https://reinhardt-web.dev/quickstart/v0.1.0-rc.18 release: Crates.io (published as reinhardt-web; the shorter name was taken): https://crates.io/crates/reinhardt-webBSD 3-Clause.Apr 22, 2026 1:00 PM

Instead of writing my manuscript, I built a toolhttps://news.ycombinator.com/item?id=47849297Hi my name is Jeff, and I am a chronic procrastinator when it comes to my writing…Tell me that doesn’t sound familiar, I’ve literally written two blogs about this instead of actually writing my manuscript, cause literally anything (even scrubbing the toilet) is more compelling than the grind of getting through chapter 6.I actually started writing a tool in early January 2025. At the time, I was trying to find a way to gamify my writing. I wasn’t really looking to launch a serious writing tool at the time, just find a way to hack my brain into doing the work (and find another excuse to not write).The result of that was a simple text box with a word counter (0/500 words) that used a little bit of JavaScript to count the words you dumped in the box, deduct any shorter than 3 letters and then let you know if you hit your writing goal for the day (and you even got some fireworks!)The tool worked, I found myself anticipating pasting my daily writing progress into the box for that dopamine reApr 21, 2026 2:25 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.

I really wanted to make a site that doesn't operate in that way.Some of its distinctions: - You can create one post per week. 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

Getting back into photography, ditching the phone camera in 2026?https://news.ycombinator.com/item?id=47842292I've been looking through twenty-five-odd years of my own photos. The collection includes scanned 35mm and medium format images; digital pictures from a few Canon Powershot generations and a 20D SLR; and about five iPhones.I've noticed that the non-cell-phone pictures tended to be better, and that in general I seemed to have quite a bit more fun with photos taken with, well, "real" cameras. Probably the best ones were taken with the 20D, which for its time was a really nice camera, for which I was able to bring over some lenses from my film days.I wouldn't rule out more film photography but I think of that as a somewhat separate track. I'd like to get a digital camera that captures a bit more of what I enjoyed about film photography - that high image density, looking through a physical viewfinder, not necessarily curating images in real time... looking, shooting, and moving on.I've been following Fujifilm cameras for awhile in this market, having read about them here a few years ago.
