Open Chronicle – Local Screen Memory for Claude Code and Codex CLI

I built an open source version of OpenAI Chronicle. Some design decisions I made: 1. Local first: OCR uses Apple Vision, summarization supports local AI providers via Vercel AI SDK. Nothing leaves your computer. 2. Multiple Provider: exposes MCP so any coding agents can use it. 3. Swift menubar app: efficient, low-footprint 4. Blacklist apps: password managers, messaging apps (Slack, WhatsApp, Messenger), mail clients are on default blocklist. Current Limitations: 1. Mac only. Mac-first is a feature. 2. Small local models with weak structured-output support will fail on generateObject. 3.…

What it does

Local screen memory for Claude Code and Codex CLI. - Screenata/open-chronicle

Give your AI coding agent photographic memory. Local screen capture → on-device OCR → LLM summaries → exposed to Claude Code and Codex CLI over MCP. Runs 100% offline with Ollama or LM Studio — or plug in any cloud LLM (Anthropic / OpenAI / Fireworks). "Continue where I left off ." — Claude has no idea where you left off. AI coding agents forget your context the moment you switch apps. Open Chronicle fixes that by giving them a rolling, local, screen-derived memory of what you were just doing. Install is source-based for now — the binary isn't code-signed / notarized yet, so Gatekeeper would block a downloaded .app for most users. Clone and build locally: git clone…from github.com

    I built LocalGPT over 4 nights as a Rust reimagining of the OpenClaw assistant pattern (markdown-based persistent memory, autonomous heartbeat tasks, skills system). It compiles to a single ~27MB binary — no Node.js, Docker, or Python required. Key features: - Persistent memory via markdown files (MEMORY, HEARTBEAT, SOUL markdown files) — compatible with OpenClaw's format - Full-text search (SQLite FTS5) + semantic search (local embeddings, no API key needed) - Autonomous heartbeat runner that checks tasks on a configurable interval - CLI + web interface + desktop GUI - Multi-provider:…

  • Open Codex – OpenAI Codex CLI with open-source LLMs2025 · github.com · ▲106

    Hey HN, I’ve built Open Codex, a fully local, open-source alternative to OpenAI’s Codex CLI. My initial plan was to fork their project and extend it. I even started doing that. But it turned out their code has several leaky abstractions, which made it hard to override core behavior cleanly. Shortly after, OpenAI introduced breaking changes. Maintaining my customizations on top became increasingly difficult. So I rewrote the whole thing from scratch using Python. My version is designed to support local LLMs. Right now, it only works with phi-4-mini (GGUF) via…

  • NotesOllama – I added local LLM support to Apple Notes (through Ollama)2024 · smallest.app · ▲156

    This lets you talk to local LLMs in Apple Notes. I saw Obsidian Ollama (https://github.com/hinterdupfinger/obsidian-ollama) and thought it was handy, but I'm too lazy to migrate away from the Apple ecosystem, so I quickly hacked this together. I tend to use Notes as a scratchpad for prompts, so it's nice to do some quick inference without leaving the app. Notes doesn't really support plugins so I'm using the macOS accessibility API for reading selections and then stream responses using the clipboard (not ideal but it works).
