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.
A real clinical thought, followed from the moment it's typed to the day it becomes a case report. Tap any step to open it.
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.
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.
"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"
Works for any kind of thinking: a clinical case, a product decision, a research thread.
You talk on the left. Your structured memory grows on the right: every entry dated, tagged, and linked to what came before.
If onboarding tripped you up, or a capture didn't save, or the model wouldn't connect: tell us exactly what went wrong. We read every one of these and fix the onboarding path directly. No ticket queue, no bot.
If you want to partner, invest, or bring Rhinal to your institution or cohort, start a conversation. Tell us who you are and what you have in mind, and we'll get back to you directly.
I'm building Rhinal because I kept a thought at 2am and lost it by morning.
I'm a third-year MBBS student at JGMCH. On night duty, the thought that mattered (the finding that didn't fit the working diagnosis, the thing my senior said in passing that I'd need in three days) never survived until I had time to write it down properly. By morning it was just gone, replaced by the next patient.
When fast, cheap AI inference became real, it was obvious what to build: something that catches the thought the moment it happens and does the structuring for you. Not another notes app. Something that tells you when you've contradicted your own reasoning, tracks whether your predictions were right, and remembers what you were thinking three weeks ago so you don't have to.
Rhinal is free to start, lives in your own Notion, and doesn't ask a hospital's permission to exist. If you're the kind of clinician who thinks between shifts and loses half of it, try it, and tell me what's broken. I read every message myself.
The longer you track a line of work, the more it holds that nothing else can. Setup takes about a minute.
