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.

Onboarding0 is an AI agent that transforms a company's scattered documentation and organizational knowledge into a structured, personalized onboarding experience for new hires. Built by Leon Arnovitz (former VP of Engineering), the tool connects to existing docs, maps the org structure, and then deploys an AI agent that guides each new employee to productivity — replacing the patchwork of wikis, Slack DMs, and first-day confusion that plagues most companies. The core insight is that onboarding failure is usually a knowledge retrieval problem, not a motivation problem. New hires spend weeks hunting for the right person to ask or the right document to read. Onboarding0's agent knows the entire knowledge graph upfront and serves answers proactively, adapting to each hire's role and department. Onboarding0 is currently free, which makes it an easy experiment for any startup or mid-size company tired of watching expensive new hires flounder in week one. The agentic approach distinguishes it from static wikis like Confluence or Notion — the agent asks follow-up questions, routes to the right person when it hits the edges of its knowledge, and tracks what each new hire has actually understood.
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.”
“Solving onboarding with an agent that actually knows your specific company context — not generic advice — is exactly right. Free tier makes it trivial to try. Built by someone who's clearly run engineering teams and felt this pain.”
“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.”
“Onboarding quality depends entirely on the quality of your existing documentation — and most companies' docs are a mess. If the source material is outdated or incomplete, the AI agent confidently guides new hires into a swamp of wrong information.”
“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.”
“The corporate knowledge graph problem is enormous and underserved. An agentic layer that makes institutional knowledge queryable and interactive is the right direction — Onboarding0 is a wedge into a massive HR tech displacement.”
“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.”
“First-day experience matters enormously for retention and culture. An AI guide that knows where everything is and can answer 'how does the design review process work here?' is what every new creative hire desperately needs.”
