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.

Velo lets you record or upload anything — slides, PDFs, docs, screen recordings, websites — and instantly converts it into a polished video message narrated by a hyper-realistic AI avatar with lip sync, eye blinks, and natural gestures. The whole workflow runs in-browser with no downloads required. The key insight is async communication fatigue: teams are drowning in wall-of-text Slack messages and poorly-produced Loom videos, but nobody has time to polish a proper recording. Velo fills the gap by letting you share a PDF, pick a voice, and ship a professional-looking walkthrough in under two minutes. It launched on Product Hunt today and hit #1 with 464 upvotes — unusually strong traction for a non-developer tool. The avatar quality is notably better than earlier AI presenter tools. Early users are reporting it as a replacement for Loom in cases where they want a "polished" look without showing their face or spending time on editing.
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 in-browser workflow is genuinely frictionless — paste a link, pick a voice, done. This is the kind of async communication tool I'd actually use instead of recording another mediocre Loom.”
“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.”
“AI avatars in 2026 still read as 'uncanny valley corporate' and that's going to cap adoption in informal team settings. Also no pricing transparency at launch is a red flag — freemium often means 'free for 30 seconds of video.'”
“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.”
“Async video is eating synchronous meetings and Velo's approach — no face, no setup, just content — could accelerate that significantly for distributed teams. This is what the next generation of internal communication looks like.”
“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.”
“As a content creator I've been waiting for a tool that makes me look polished without a studio setup. The avatar quality here actually clears my bar — I'd use this for client-facing walkthroughs without hesitation.”
