InstaCal

About

InstaCal lets you create and edit Google Calendar events using plain English.
Just type something like “Lunch with Sarah tomorrow at noon” and InstaCal instantly parses it and adds it to your calendar.

Designed for speed, InstaCal helps you schedule events, modify them with AI, and share your availability in seconds.

CREATE EVENTS WITH NATURAL LANGUAGE

Skip the calendar forms and just type what you mean.

Examples:
• Dentist appointment in 3 days at 2pm
• Team lunch Friday at noon at CTB
• meet w/ yaelin tmw, 4, olin lib

InstaCal’s AI automatically extracts:
• Event title
• Date and time
• Duration
• Location
• Description
• Recurrence
• Attendees

Choose between:
• Auto-Add Mode — events are created instantly
• Review Mode — opens the prefilled Google Calendar editor

EDIT CALENDAR EVENTS WITH AI

InstaCal adds an “Edit with AI” button directly to Google Calendar event pages.

Just describe what you want:
• “Move this meeting to 3pm”
• “Add a Zoom link”
• “Change location to Baker Lab”

The event updates automatically — no manual editing required.

ADD EVENTS FROM ANYWHERE

Highlight text on any webpage, right-click, and select “Add to Calendar with InstaCal.”

The text is instantly loaded into InstaCal and parsed into an event.

Perfect for scheduling from:
• emails
• documents
• event pages
• messages

INSTANTLY SHARE YOUR AVAILABILITY

Select a date range and InstaCal will generate a plain-text list of your free time slots.

Your availability is copied to your clipboard so you can paste it into:
• emails
• Slack messages
• meeting requests

SMART CONTACTS FOR ATTENDEES

Save contacts so InstaCal can automatically resolve attendees when they appear in events.

If a new person is mentioned, InstaCal prompts you to add their email and optionally save them for future use.

Contacts sync across your devices.

CUSTOMIZABLE SCHEDULING PREFERENCES

Personalize how events are created with options like:

• Auto-add events directly to Calendar
• Smart time and duration defaults
• Default start time and duration
• Default location
• Convert tasks into all-day events
• Automatically notify attendees
• Define working hours for availability sharing

BUILT FOR SPEED

InstaCal integrates directly with Google Calendar to make scheduling fast, simple, and frictionless.

Just type and schedule.
