A thought, carried further
A reading note, a research diary, a draft. Give it shape with formatted text, then keep images, recordings and files beside the words they belong to.
Open an inline attachment marker to see the image over the paragraph it belongs to, without losing your place.
Find papers in PubMed or OpenAlex, bring in your Zotero library, and add citations as you write. Your folder bibliography stays close at hand.
Import RIS and BibTeX. Export your bibliography as Vancouver, APA, IEEE or Harvard text, or as RIS, BibTeX and CSV. Numbered citations follow their order of appearance.
Find an entry by date, or follow related notes along a timeline. Come back to the context, not just the title.
Move through your entries with the date scrubber, or choose a day in the calendar. Optional Apple Calendar integration brings your alerts into view.
Earlier beta screens captured in September 2026, with sample titles tidied for presentation. The current app may look different. The teaching material shown contains no patient data.
A thought on the go
Record on your wrist. Send it to your iPhone. Turn voice into text on your device after the initial model setup.
The Watch companion records and hands the audio to your paired iPhone. Transcription runs on your device.
Made for your everyday
Shelves, folders and labels for the way you work.
Templates for the notes you write again and again.
Light and dark appearances, with workspace backgrounds you can choose.
Find your light. Settle into your work.
Bring in your own SCImago CSV and keep a journal table for each year. Search the SJR value, quartile, subject area and publisher from your imported file.
Hikari shows what your table contains. It does not connect to an external metrics service.
Why Hikari exists
I’m a neurosurgeon and researcher. I started Hikari because my notes, papers, images and drafts kept ending up in different places. I wanted a calmer way to work with them together, across the Apple devices I use every day.
Hikari is now in public beta. If it fits the way you think and work, I’d love your help shaping what comes next.
Beta availability
The shared TestFlight invitation remains available.
It may currently offer an older iOS beta.
The refreshed iPhone/iPad and Mac beta is undergoing release checks and has not been opened for public testing. An older iOS build offered by the invitation is not the release candidate currently being checked.
Requires iOS, iPadOS or macOS 26 or later; the companion requires watchOS 26 or later and comes with the iPhone app.
No separate Hikari account needed. TestFlight shows the builds currently offered to you.
Before you begin
Open the shared invitation above. It may currently show an older iOS beta while the refreshed iPhone/iPad and Mac beta undergoes release checks. That older build is not the release candidate currently being checked. TestFlight shows whether a compatible build is offered for your device. Keep a separate copy of important work when testing.
The same invitation is intended for Hikari Scribe on iPhone, iPad and Mac. The refreshed beta has not yet been opened for public testing. The Apple Watch companion comes with the iPhone app. If TestFlight does not offer a compatible build, contact Support with your device and system version.
Send feedback through TestFlight or write to feedback@hikariscribe.app. Include your device, system version, app build and the steps that led to the problem.
You can also check the known issues or visit Support.
