01
Name the feeling
Find what the letter is really carrying before the first sentence.
Handwritten letters, prepared with care
Write the handwritten letter you’ve been meaning to write.
SLOWKEPT gives you an Early Free Letter Guide, printable stationery, and an optional private timeline for the chosen moments around a physical letter. You choose and write every word yourself.
Begin with the Early Free Letter Guide. A Private Thread is optional and belongs only around a physical letter that is ready to be sent.
Have a Private Thread Code?
Enter the Code and open the existing private timeline.
A recipient can use a valid Private Thread Code without creating an account first, then choose whether to leave a permitted shared update.
Early Free Letter Guide
A guided starting point before you write the physical letter.
Before the first sentence, SLOWKEPT helps you slow down: name what you are carrying, check what the letter should not become, and decide whether the next step is Send, Wait, or Save.
It does not write the letter for you. It helps you arrive at your own words.
The Early Free Letter Guide is available in early access. Its prompts, order, and wording may continue to evolve as we refine it.
02
Check the boundary
Make sure the letter does not become pressure, performance, or regret.
03
Find the first line
Begin with one safe sentence instead of forcing the whole letter open.
04
Write by hand
Keep the letter physical, private, and away from the website.
05
Send / Wait / Save
Choose the next quiet step only after the letter is written.
Writing by hand
The letter becomes real away from the screen.
SLOWKEPT prepares the moment around the letter. The private words stay with the person writing them: on paper, in hand, and outside a message thread.
A Private Thread
A timeline for letters, not messages.
A paid Ongoing Private Thread Code opens one private timeline that can continue across multiple physical-letter rounds. The First Private Thread Demo uses a separate Code and one limited round.
One paid Ongoing Private Thread
A paid Ongoing Private Thread can continue across multiple physical-letter rounds with the same active Code.
One Private Thread Code
The recipient can enter the Code and leave a permitted shared update without creating an account first.
Physical-letter events and shared updates
The timeline records physical handoff events and the optional shared updates either person deliberately submits. The First Private Thread Demo remains limited to one round.
Demos
See the difference between the visual example and the one-time Demo.
The visual example shows how a paid Ongoing Private Thread may continue across multiple physical-letter rounds and saves nothing. The First Private Thread Demo is a separate one-time free experience with one limited round.
Ongoing Thread visual example
Multiple letter rounds, shown clearly
See a sample paid Ongoing Private Thread across more than one physical-letter round. It contains no real Codes or customer information.
First Private Thread Demo
First Private Thread Demo
Use one real, limited private timeline with a recipient Code. Each verified account can create it successfully once.
Need an ongoing letter timeline?
Ongoing Private Threads are separate one-time purchases for correspondence that continues beyond the single Demo round.
Privacy boundary
Your letter stays yours.
The physical letter remains yours. SLOWKEPT keeps only the shared updates and private notes you deliberately add around it.
Your full letter remains outside SLOWKEPT
Only deliberate timeline events and shared updates appear
Private notes stay visible only to their author
Opening a page never creates a read receipt
What it is
A guided path from blank page to finished letter.
Start with the Early Free Letter Guide, write in your own voice, and choose the next step only when the letter feels ready.
What remains in your control
Your words, timing, and decision.
You decide what to write, whether to send, and whether to use a Private Thread. The product supports the process without taking over the letter.
Early Free Letter Guide
Start with one letter, one guide, and one unhurried decision.
Use the current guided questions, choose a printable page, and move toward a letter that sounds like you.
