Drop in plain text, a flyer photo, a public events page URL, a CSV, or an existing calendar file. Calfeed reads it and builds the feed. You get one stable link that works in Apple Calendar, Google Calendar, Outlook, Microsoft 365, and Yahoo.

Edit once, everyone gets it. Change a time in Calfeed and every subscriber's calendar updates on its own โ€” no re-share, no message blast, same link forever.

Make it yours: drop in a logo and a color, and the public page looks like your brand. Embed it on your site with a single snippet that auto-resizes and stays in sync.

Built for parents managing kid schedules, coaches and trainers running classes, organizers coordinating community events, and creators who post regular content. Anyone who keeps repeating "here's the updated schedule" stops repeating it.

Questions & Answers

As answered by people managing Haystack Analytics and Calfeed.

How would you describe the primary audience of your product?

Haystack Analytics's answer

Engineering Leaders and Managers

Calfeed's answer:

Anyone who keeps re-sharing the same schedule: parents tracking kid sports and school events, coaches and trainers running classes, organizers coordinating community events, and creators with regular programming. Pro/creator users layer on logos, custom colors, and embeds for a branded public page.

What makes your product unique?

Calfeed's answer:

Calfeed is the only calendar tool built AI-first โ€” paste a schedule in plain text (or drop a flyer photo, URL, or CSV) and get a shareable feed back. Every competitor still uses one-event-at-a-time form fields built for the Outlook 97 era.

Why should a person choose your product over its competitors?

Calfeed's answer:

Calfeed turns "here's the updated schedule" into a one-time subscription instead of a recurring group text. Tools like AddEvent and AddCal still make you fill out a form per event; Calfeed reads what you already have and publishes a feed that updates itself.

What's the story behind your product?

Calfeed's answer:

Built after watching the same friction play out everywhere โ€” coaches retyping practice changes, parents juggling four kid calendars, organizers blasting "updated schedule" texts. The fix wasn't a better form; it was treating a schedule as text the way humans actually write it, and a calendar as a feed the way subscribers actually consume it.

Which are the primary technologies used for building your product?

Calfeed's answer:

Next.js 16 + React 19 + Tailwind on Vercel, Postgres via Neon with Drizzle ORM, Stripe for billing, Resend for transactional email, and Anthropic Claude for turning plain text into structured events.

Who are some of the biggest customers of your product?

Calfeed's answer:

The biggest customers are people that schedule often. Someone who needs to set up calendars for clients or events.
