CalendarPipe is a programmable calendar synchronization layer designed for both humans and AI agents. You write rules and logic to control how events sync across calendar services — filtering by attendee, keyword, or event type, transforming event details, or routing events to different calendars based on custom conditions. An API surface lets agents call CalendarPipe directly to schedule, reschedule, read availability, or block time without human intervention. The tool addresses a real pain point in agent workflows: calendar access. Most AI assistants and agents can read calendar state, but modifying it requires either fragile OAuth flows or screen-scraping. CalendarPipe provides a stable API with scoped permissions, making it safer to give an agent calendar write access without risking it touching events it shouldn't. Launched today on Product Hunt, CalendarPipe targets productivity power users, small teams using AI assistants for scheduling, and developers building agents that need to manage time on behalf of users. The programmable rules engine differentiates it from simpler calendar sync tools like Fantastical or Reclaim.ai.

King Louie is an open-source, cross-platform desktop AI assistant that runs entirely on your machine with no cloud dependency beyond whatever LLM API you choose to connect. It supports 13 LLM providers out of the box (including local models via Ollama), ships with 20 built-in agent tools covering bash, file operations, git, browser automation, web search, and code execution, and uses semantic embeddings for persistent cross-session memory. The feature that sets King Louie apart from every other "local AI" project is its P2P mesh networking layer. Multiple King Louie instances can discover each other and share tasks across a network — think a home lab where your desktop and laptop AI agents coordinate on the same workflow. Combined with built-in bridges to Telegram, Discord, and Slack bots, it turns a local AI assistant into a distributed agent network you fully control. AI-powered model routing lets you define rules for which LLM gets which type of request — route code tasks to your local DeepSeek instance, creative writing to Claude, quick lookups to a fast small model. The whole thing runs as an Electron app on Windows, Mac, and Linux. It's early but the architectural ambitions are unusually coherent for an indie project.
Reviewer scorecard
“The agent-accessible API is the right idea at the right time. I've been manually writing calendar integrations for every scheduling agent I build — a stable, scoped API with rule-based permissions is exactly what I need to stop reinventing this wheel. The programmable sync engine is a bonus.”
“The P2P mesh networking between agent instances is the sleeper feature here — distributed local AI coordination that you actually own is not something any commercial product offers. The 13-provider model routing layer means you can optimize cost and capability per task type. Solid base for a power-user local agent setup.”
“Calendar sync tools have a brutal churn rate — Fantastical, Reclaim, Motion, and a dozen others already fight for this space. Without public pricing, it's hard to evaluate value. The 'AI agent API' angle is novel but thin; if Google Calendar or Notion Calendar ever adds decent MCP support, this moat evaporates overnight.”
“Electron apps with AI model routing, P2P networking, and bot bridging all in one are ambitious to the point of instability. Each of those features is a complex subsystem that requires serious ongoing maintenance. Indie solo project ambition often outpaces execution capacity — wait to see if the project sustains past its initial hype week.”
“Time is the most underrated context for AI agents. An agent that can see your calendar — and modify it with your blessing — can reason about energy, priorities, and scheduling in a way no chat-only assistant can. CalendarPipe is early infrastructure for the 'agent that manages your week' category that's coming.”
“King Louie sketches out what personal AI infrastructure looks like: mesh-connected local agents with intelligent routing that you own end to end. This is the architecture that beats the 'one cloud AI to rule them all' model on privacy, latency, and cost — it just needs to mature.”
“As a freelancer juggling multiple clients and platforms, the cross-service sync with custom rules is genuinely useful even without the AI angle. Being able to automatically route client calls to one calendar and personal events to another based on keywords would save me real setup time every week.”
“For freelancers and studios that work across multiple machines, the P2P mesh means your creative AI agent stays in sync between your desktop and laptop without trusting a cloud sync service with your work-in-progress files. The Telegram/Discord bridge means your AI is reachable wherever your team already is.”
