Built for clinical researchers — and anyone whose thinking has stakes

You forgetyour best ideas.Rhinal doesn't.

Built for the 2am ward observation, the mid-meeting decision, the research insight that vanishes before you can write it down. Rhinal structures your thinking and keeps it in your own Notion — privately, without guessing.

The problem

You lose your best thinking.

A sharp observation at work. A decision and the reason behind it. A pattern you noticed across a week. You mean to write it down — and by next week it's gone, or buried in notes you never reopen. The thinking that matters most is the easiest to lose.

Why it's different

It organizes — and it never guesses.

Most note apps just store your words in a pile. Most AI tools forget what you said, or fill the gaps with confident guesses. Rhinal does neither — it tidies your messy thought into a clean, dated, connected record using only what you actually said, and asks one sharp question when something's unclear.

What you dump in

"ok so we decided to push the launch to march instead of feb, mainly because the payments integration isn't ready and rohan said QA needs 3 more weeks, also we don't want to clash with the competitor's release"

What Rhinal keeps
Launch moved to March
Delayed from February: payments integration incomplete, QA needs 3 more weeks, and to avoid clashing with a competitor's release.
DecisionProduct

Works for any kind of thinking — a clinical case, a product decision, a research thread.

Architecture

You talk on the left. Your structured memory grows on the right — every entry dated, tagged, and linked to what came before.

It compounds
Every entry is dated and linked to related ones. A line of work becomes a living map — worth more each week, and impossible to rebuild anywhere else.
It never guesses
When a thought is unclear, Rhinal asks one sharp question instead of inventing the missing detail. What's saved is only what you actually said.
It stays yours
Runs on your own model — free and private on your machine, or your own cloud key. Stored in your own Notion. No server reads your thinking.
Who it's for

If your ideas are worth keeping, it's for you.

Built from clinical practice, first
Clinical researchers
Track a case or study across months.
Founders & ops
Capture decisions and the reasoning behind them.
Writers & students
Turn scattered notes into structured thinking.
High-stakes thinkers
If forgetting it would cost you something, it's worth saving.

Start with one thought.

The longer you track a line of work, the more it holds that nothing else can. Setup takes about a minute.
