Extract Calendar Events from Images Automatically

Every month, millions of parents face the same tedious task: transcribing school calendars, sports schedules, and event flyers into their phones. One event at a time. Two to three minutes per event. Hoping they don't make a typo that causes them to miss something important.

A typical school calendar image with 40-50 events? That's 2+ hours of manual data entry. And you do it again next month.

There's a better way: extract calendar events from images automatically with AI.

The Problem With Manual Calendar Entry

Here's the reality for busy parents and families using apps like Cozi:

• Time sink: Average 2-3 minutes to manually enter one event into Cozi
• Error-prone: Typos in dates, times, or locations lead to missed events
• Recurring burden: New calendar every month means repeating the process
• Psychological cost: You dread doing it, so you procrastinate, which creates stress
• Cozi's limitations: No AI extraction, read-only Google sync, 30-day free tier limit

And it's not just parents. Teams, organizations, and anyone managing shared calendars faces the same friction. The difference? AI extraction makes it optional.

Extract Calendar Events from Any Image with AI

Calendara uses AI to extract calendar events from any image—school flyers, PDFs, screenshots, photos, WhatsApp messages, Instagram stories. Any image with calendar information.

The transformation when you extract events from images:

• Before: 2 hours of manual typing → After: 30 seconds of AI extraction from image
• Before: Human error in dates/times → After: 90%+ accuracy from image extraction
• Before: Dreading the monthly calendar update → After: Upload image, done

How to Extract Calendar Events from Images

It's ridiculously simple (see the full step-by-step guide):

1. Upload any image - School calendars, sports schedules, event flyers, WhatsApp screenshots
2. AI extracts events from image - Dates, times, locations, descriptions automatically detected
3. Review & save - Quick accuracy check (rarely needed), then save to your calendar

The AI handles complex formats:

• Multi-month calendars
• All-day events vs. timed events
• Recurring events
• Color-coded event types
• Dense schedules (we've successfully extracted 48 events from a single image)

Real-World Example: Extracting Events from a School Calendar Image

Input: School calendar PDF image with 48 events (holidays, half-days, parent-teacher conferences, special events)

AI Processing Time: 15 seconds to extract calendar events from image

Extracted Events: 48 events with 90%+ accuracy

Time Saved: 2+ hours by extracting from image instead of typing

Errors to Correct: 2-3 minor formatting tweaks

That's the power of extracting calendar events from images with AI. What used to take an entire evening now takes less time than making coffee. Read the founder's story about why this tool was created.

Who This Is For

Parents: Stop typing school calendars, sports schedules, and activity flyers

Families: Coordinate everyone's schedules without the manual data entry

Teams: Share event calendars without asking everyone to type them in

Organizations: Distribute calendars to members without email chains

Daycares & Schools: Create calendars once, let parents subscribe automatically

Beyond Extraction: The Full Calendar Experience

Once events are extracted, you can:

• Share calendars via QR code or link
• Enable automatic updates - Change event once, everyone gets it
• Sync with Google Calendar, Apple Calendar, Outlook
• Manage multiple calendars - School, sports, work, all in one place
• Set reminders - Never miss important events

The extraction is just the beginning. The goal is to eliminate all the friction around calendar management.

The Technical Details

For those interested in how this works:

We use multiple AI models (Claude 3.5 Haiku, Gemini 2.5 Flash, GPT-4o) in a waterfall approach for maximum reliability. The AI is trained to understand:

• Date formats - MM/DD, DD/MM, written dates, relative dates ("Next Tuesday")
• Time formats - 12-hour, 24-hour, time ranges, all-day events
• Recurring patterns - Weekly, monthly, custom recurrence
• Context clues - Location names, event types, implicit information

The accuracy comes from:

1. Multimodal AI: Can see and understand images, not just text
2. Structured output: Trained to output calendar-compatible data
3. Context awareness: Understands what makes sense for calendar events
4. Model fallback: If one AI struggles, we automatically try the next

Supported Image Formats for Event Extraction

Upload virtually any image type to extract calendar events from:

• PDFs - School calendars, event programs
• Screenshots - From any device or app
• Photos - Printed schedules, whiteboards, event posters
• Image formats - JPEG, PNG, HEIC, and more

What's Next

AI extraction is live now, but we're already working on:

• Bulk extraction - Multiple images at once
• Email integration - Forward calendar emails for extraction
• Calendar intelligence - Suggest optimal times, detect conflicts
• Natural language input - "Add team lunch every Tuesday at 12"

The vision: You should never manually type calendar information again.
