Why journal in 2026?
Principles
This isn't an average diary. It's got character.
One Note Per Day
Your life isn’t a Twitter feed. By forcing a single daily entry, we stop the "micro-posting" habit. It forces you to actually synthesize your day into one meaningful snapshot rather than a series of disconnected, impulsive thoughts.
No Edits*
Real life doesn't have an "undo" button. When you can’t polish or delete your past, you’re forced to accept your own growth—messy drafts and all. It’s an authentic 3D receipt of who you were at that exact moment. * You can edit note before end of the day
The 100-Word Minimum
Anything less is just a status update. Reaching 100 words forces your brain to move past surface-level "I'm tired" venting and actually start digging into why. It’s the threshold where "complaining" turns into actual self-reflection.
Prominent voices
They understood
the power of writing.
Leo Tolstoy
Author — kept diaries for 63 years
"I write to understand what I think. A thought unwritten is a thought half-formed. The diary is not a record of life — it is life itself, examined."
Virginia Woolf
Author — wrote journals from age 15
"The habit of writing for my eye is good practice. It loosens the ligaments. Never mind the misses and the stumbles."
Marcus Aurelius
Roman Emperor — Meditations, 161 AD
"You have power over your mind, not outside events. Realize this, and you will find strength. The journal is where I found mine."
Carl Jung
Psychiatrist — wrote the Red Book for 16 years
"Until you make the unconscious conscious, it will direct your life and you will call it fate. Writing is how I made it conscious."

Questions
Answers.
Will my journal entries stay private?
We use AES-256-GCM authenticated encryption to protect every entry. Your data is encrypted at the database level, meaning even if someone gained access to the raw database, your words would look like a chaotic string of random characters. With Row-Level Security (RLS) combined with encryption, only your authenticated session can trigger the decryption process.
Is the app available for Android and iOS?
100 Words is a Progressive Web App. Install it on Android or iOS directly from your browser — no app store required. It works offline, too.
Can I export my journal entries?
Yes. Download all your data in plain text or CSV at any time. Your journal is yours — we never lock you in. Export is free on all plans.
Does the Pro plan use AI to write for me?
No. AI in Pro only reads and reflects back — it offers insights and patterns after you've written. It never writes entries for you. The words are always yours.
