Visual Builder

The Visual Builder lets you create gate functions by selecting conditions and actions from dropdown menus. No coding required -- just pick event properties, choose operators, set values, and define what happens when conditions match.

Screenshot: Visual Builder interface with condition and action panels

How It Works

The Visual Builder generates a gate function from three components:

1. Conditions -- Rules that evaluate event properties (e.g., "Title contains meeting")
2. Combinator -- How multiple conditions are joined: AND (all must match) or OR (any can match)
3. Action -- What happens when conditions match: Pass (sync the event) or Block (skip the event), with optional transforms

When CalendarPipe syncs events, each event is checked against your conditions. If the conditions match, the action is applied. If the conditions don't match, the opposite action is applied (i.e., if the action is "Block", non-matching events are passed through).

Adding Conditions

Click Add Condition to create a new rule. Each condition has three parts:

1. Property -- The event property to evaluate
2. Operator -- How to compare the property value
3. Value -- The value to compare against

Condition Properties

The Visual Builder supports 12 event properties, organized by type:

Text Properties

Property	Description	Example Values
Title	Event title/summary	"Team Standup", "Lunch"
Description	Event description/notes	"Weekly sync meeting"
Location	Event location	"Conference Room A", "Zoom"
Organizer	Organizer's email address	"alice@example.com"

Number Properties

Property	Description	Example Values
Duration (min)	Event length in minutes	30, 60, 120
Attendee count	Number of attendees	1, 5, 20
Hour	Hour of day the event starts (0-23)	9, 14, 17

Boolean Properties

Property	Description	Values
Is weekday	Whether the event falls on Monday-Friday	true / false
Is all-day	Whether the event is an all-day event	true / false

Special Properties

Property	Type	Values
Day of week	Day picker	Sunday (0) through Saturday (6)
Visibility	Enum	default, public, private
Show as	Enum	free, busy

Operators Reference

Different property types have different operators available:

Screenshot: Operator dropdown for a text property

Text Operators

Operator	Description	Example
contains	Value appears anywhere in the text	Title contains "meeting"
not contains	Value does not appear in the text	Title not contains "personal"
equals	Exact match	Location equals "Remote"
not equals	Does not exactly match	Organizer not equals "bot@example.com"
starts with	Text begins with value	Title starts with "[PROJ]"
ends with	Text ends with value	Title ends with "(optional)"

info

All text matching is case-insensitive. "Meeting", "meeting", and "MEETING" are all equivalent.

Number Operators

Operator	Description	Example
equals	Equal to value	Duration equals 30
not equals	Not equal to value	Attendee count not equals 1
>	Greater than	Hour > 17
<	Less than	Duration < 15
>=	Greater than or equal to	Attendee count >= 5
<=	Less than or equal to	Hour <= 9

Boolean Operators

Operator	Description	Example
is true	Property is true	Is weekday is true
is false	Property is false	Is all-day is false

Enum Operators

Operator	Description	Example
equals	Matches the selected value	Show as equals "free"
not equals	Does not match the selected value	Visibility not equals "private"

Combinators

When you have multiple conditions, the combinator determines how they're evaluated:

• AND (default) -- All conditions must match for the action to apply
• OR -- Any condition matching triggers the action

For example, with two conditions "Title contains meeting" AND "Is weekday is true":

• A weekday event titled "Team Meeting" -- both conditions match, action applies
• A weekend event titled "Team Meeting" -- only one condition matches, action does NOT apply (with AND)
• A weekday event titled "Lunch" -- only one condition matches, action does NOT apply (with AND)

With OR, the action would apply if either condition matches.

Actions

The action defines what happens to events that match your conditions:

Screenshot: Action configuration panel with Pass/Block toggle and transform options

Pass or Block

Action	When conditions match	When conditions don't match
Pass	Event is synced	Event is blocked
Block	Event is blocked	Event is synced

Optional Transform

When passing events, you can optionally transform them by overriding these properties on the synced copy:

Field	Description	Values
Title	Replace the event title	Any text (max 500 characters)
Description	Replace the event description	Any text (max 5,000 characters)
Visibility	Change event visibility	default, public, private
Show as	Change free/busy status	free, busy

tip

Transforms only apply to the synced copy on the target calendar. The original event on the source calendar is never modified.

Step-by-Step Examples

Example 1: Block Weekend Events

Block events that fall on weekends, only syncing weekday events.

1. Click Add Condition
2. Select property: Is weekday
3. Select operator: is false
4. Set action to: Block
5. Save

Result: Events on Saturday and Sunday are blocked. Weekday events sync normally.

Example 2: Redact 1-on-1 Meetings

Pass all events, but replace the title of small meetings that look like 1:1s.

1. Click Add Condition
2. Select property: Attendee count, operator: <=, value: 2
3. Click Add Condition again
4. Select property: Title, operator: contains, value: 1:1
5. Set combinator to: AND
6. Set action to: Pass
7. Enable transform, set title to: Meeting
8. Save

Result: Events with 2 or fewer attendees AND "1:1" in the title are synced with the title replaced by "Meeting". All other events sync unchanged.

Example 3: Only Sync Long Meetings

Pass events that are 60 minutes or longer, block everything else.

1. Click Add Condition
2. Select property: Duration (min), operator: >=, value: 60
3. Set action to: Pass
4. Save

Result: Only events lasting 1 hour or more are synced. Short events (under 60 minutes) are blocked.
