For knowledge workers
A journal for people whose job is thinking.
If you close your laptop with nine tabs open in your head every night, this is for you. Write the unresolved bits down. Prism reads across the week and gives you the shape of what your brain was actually working on.
The problem
Your best thinking happens when nobody is taking notes.
On the walk home. In the shower. Fifteen minutes before a meeting you don't want. The realisations you have there are load-bearing — they rearrange how you see a project — and they almost never reach your doc or your slack.
Prism is the place those loose realisations land. A sentence, a voice note, a half-thought. It does not ask you to structure them. It reads across weeks and surfaces the ones that repeat.
How it reads you
The Mirror, every Sunday, in the voice of someone who read the whole week.
Each entry is classified, themed, tagged, and embedded. Not to categorise you, but so that when you write about the same client under three different framings, Prism knows they are the same client and draws the line for you.
Sunday morning you get a Mirror — a literary reading of your week, with evidence pulled from your own entries. It is the closest thing you will get to a colleague who reads everything you think and gives you a five-minute summary.
What you build
An archive of the parts nobody else sees.
Six months in, the Behavioural Profile is a high-resolution picture of what you actually work on — not what is on your calendar, what has your attention. The gap between those two things is usually the most important number in a knowledge worker's life. Prism finally makes it visible.
A year in, the archive is also a defence. If you leave a job, if you pivot, if a role disappears, what you have on Prism is a record of how you think that nobody else can fire you from.
Common questions
Before you sign up.
How is this different from a second brain tool?
A second brain is a filing system you maintain. Prism is a reader you do not maintain — it consumes your loose writing and gives you weekly synthesis. A lot of people keep both.
Does it work if I type, dictate, or both?
Both. Voice notes transcribe to text and go through the same pipeline. Some users dictate on walks and type at the desk — the Mirror doesn't care.
What happens to my entries if I cancel?
You can export the full archive as JSON or Markdown. Delete is immediate and irreversible. We do not hold your data hostage.
Is this AI writing for me?
No. You write, Prism reads. The AI is a reader on your side of the table, not a ghost-writer. Nothing you publish or send has been written by Prism.
