Kathu കത്ത് means “letter”

Remember the excitement of a wedding letter arriving at home — the kasavu border, the families’ names, the muhurtham time, sometimes on a blue inland letter? Kathu brings that feeling to WhatsApp.

We built Kathu for families who want an invitation that is beautiful, quick to make and easy for every relative to open — from the cousin in Dubai to the grandmother who prefers Malayalam. Choose a formal design or a funny one, add your functions, and share one link. Guests can reply, leave blessings, find the venue and add it to their calendar.

What we care about

• Malayalam done right. Proper fonts and correct conjuncts everywhere, including the share images.
• Privacy. Letters are only for people with the link, links can end or be paused, and we never contact your guests.
• Simple and fair. Drafts are free; you only use tokens to publish.

Who makes it

Kathu is made by VipzLab, a small product studio that also makes apps and games. Questions or ideas? Contact us.
