Your letter, written once. Sent to every name on your list.
Bring your letter and your guest list. InviteLetter makes a finished PDF for every name, and flags missing details first.
Three steps from spreadsheet to signed letters
You keep working in the spreadsheet you already have. InviteLetter uses its column names to fill the letter.
Bring your letter
Upload a blank letter as Word, PDF or a photo, and AI copies the layout and marks every part that changes. Or describe the letter you need and add your logo and signature.
Check the wording
Edit the letter on the page itself. Details from your list show as yellow tags. Ask the AI for changes in plain words, like “make the second paragraph shorter”.
Make every letter
Add your CSV. People with missing details are shown in red before you send anything. Save one PDF or a ZIP of all of them, each named the way you choose.
Built for the letters that take a whole afternoon
Invitations with a name on every one
Gala dinners, leadership summits and award evenings. Guests, speakers and sponsors, each with their own table, dates and details.
Visa invitation letters
Delegates from many countries, each needing their passport details on a signed letter.
Certificates of attendance
A certificate for every participant on the day the programme closes.
Any letter with a list behind it
If you would otherwise copy names into Word one by one, InviteLetter can do it.
Your lists are full of personal data. We don't keep any of it.
Names, ID and passport numbers, birth dates, addresses. InviteLetter uses them to make your letters and then lets them go. The AI only ever sees your letter, your column names and anything you choose to show it, such as a description or your logo. Never your lists.
Pulsar Interactive acts as your data processor under Singapore's and Thailand's PDPA, with a data processing agreement available on every paid plan.

Questions
What if the AI gets my letter wrong?
You check and edit every template before it is used. Any detail the AI could not match to a column in your list is shown in red, so nothing is filled in silently.
Do I need to change my spreadsheet?
No. Export it as CSV. InviteLetter reads the column names in the first row and uses them as the details in your letter.
Can I use my own logo and signature?
Yes. Upload them once and they are saved with the template. They are kept private to your account.
We only run one event a year. Do we need a subscription?
No. The Event Pass covers one event for 30 days and doesn't renew.
Send us the letter you dread most. See it as a template in under a minute.
