Meetings that respect
every timezone
Three free tools for remote teams — find the perfect meeting window, write inviting messages, and protect your eyes.
No signup. No data collection. Just your browser.
How MomentumKit works
Three tools. One workflow. Use them together or standalone — whatever fits your team.
Find the Overlap
Add up to 5 cities where your team is located. Our algorithm automatically excludes sleep hours (23:00–07:00) and finds the only window where everyone is awake and functional.
Generate the Invite
Choose between three tones — Polite (cross-cultural), Direct (startups), or Human (well-being focused). Copy and paste into Slack, Teams, or email in one click.
Protect Your Eyes
Get real-time brightness, color temperature, and ergonomic suggestions based on your local time. No sensors, no data — just your browser telling you what your eyes need.
Three tools, one mission
Each tool is independent, privacy-first, and works entirely in your browser. No backend, no storage, no accounts.
Meeting Overlap Finder
Enter up to 5 cities. We automatically exclude local sleep hours (11pm–7am) and find the only 2-hour window where everyone is awake. If no perfect window exists, we show the least-damaging option.
Try Overlap FinderInvite Generator
Stop writing awkward scheduling emails from scratch. Pick a tone — polite, direct, or human — and get a ready-to-paste invite that explains why the time was chosen.
Generate InvitesDisplay & Light Guide
Your local time determines the ideal brightness, color temperature, and ergonomic setup for your screen. Automated, personalized, and privacy-first.
Get SuggestionsBuilt for distributed teams
Whether you're a two-person startup or a 50-person remote company, MomentumKit scales with your timezone complexity.
Why MomentumKit is different
Most scheduling tools either collect your data or require accounts. Ours is a breath of fresh air.
No backend at all
Every calculation runs in your browser. When you close the tab, everything is gone. No servers, no databases, no data leaks.
Deterministic algorithms
No AI, no APIs, no unpredictability. Every result is 100% reproducible and auditable. You always know exactly why a time was chosen.
Automatic DST handling
Daylight saving time changes are handled automatically using your browser's Intl.DateTimeFormat. No manual adjustments needed.
Sleep hours protected
We never suggest times between 23:00–07:00 local time for any participant. Your team's rest is non-negotiable.
One-click copy
All invites include a copy button. No select-and-right-click. Just click and paste into your communication tool of choice.
Physiological context
Each participant gets a label — "Fresh", "Focused", "Getting tired" — based on their local time. You can see how people will feel, not just if they're awake.
Designed for a complete workflow
The three tools are designed to work together, creating a seamless experience from scheduling to sending.
