The Rocketbook Core Letter is a reusable spiral notebook you write in with the included Pilot FriXion pen, scan with the Rocketbook app, and wipe clean with a damp cloth once the page is full. It targets professionals who want handwritten notes with a searchable digital backup, instead of a drawer full of paper notebooks that eventually get thrown out or lost. This Green, Letter-size version measures 8.5 by 11 inches, matching a standard notepad or printer page, so a scanned note looks like a normal document rather than a cramped index card.
This review covers what the Letter Green Core does well, what to know about the write-scan-erase cycle, and which version of the notebook to actually buy, since Rocketbook sells this same notebook in an Executive size and several colors. Every spec below comes from the manufacturer listing, and nothing here is guessed at or filled in from memory of other Rocketbook models.
What the Rocketbook Core Letter Is, and Who It's For
The Core is Rocketbook's flagship reusable notebook, and this listing is the current, redesigned version with what the manufacturer calls an improved pen-to-paper feel and a scratch-resistant cover. Each grid-layout page carries a small icon strip at the bottom called Smart Titles and Smart Tags, which let you name a scanned page and route it to a specific folder or app before you even open your phone.
Write a page, scan it with the app, then wipe the page with a damp cloth and start again. That loop is the entire product, and it repeats indefinitely on the same set of pages instead of consuming new paper each time. It suits people who think best with a pen but still need their notes searchable, backed up, and shareable with a team, rather than trapped in a notebook sitting on one desk.
It's a poor fit for anyone who wants a permanent physical archive. Every page in the Core is built to be erased, so if you need to hand someone a signed original or keep a paper trail that can't be wiped, a standard notebook still does that job better.
- Best for: meeting notes, daily planning, and handwritten drafts that need to end up in a cloud folder
- Also good for: teams standardizing on one note-taking format across desks, and anyone replacing a rotating stack of paper notebooks
- Skip it if: you need a permanent paper archive, since every page is designed to be erased and reused

How the Write, Scan, Erase Cycle Works
The Core ships with one Pilot FriXion pen, the pen the whole reuse system depends on. FriXion ink responds to heat and friction, which is why a damp cloth and a light wipe can lift it off the page instead of leaving a smudge or a stain behind.
Scanning happens through the Rocketbook app, not a phone's default camera. The app squares up the page, corrects for glare, and reads the Smart Title and Smart Tag icons you marked at the bottom of the page, then routes the file to the cloud folder or app tied to that icon. The listing describes this loop as create, digitize, erase, and re-create: you write on the page, digitize it with a scan, wipe it clean, and start over on the same sheet.
That's a real shift from a normal notebook, where the page is the permanent record. Here, the scan is the permanent record and the page is just the input surface. Once you scan a page, treat the physical paper as disposable and trust the digital copy.
Scanning, Smart Titles, and Where Your Notes Go
The app connects to cloud destinations including Google Drive, Dropbox, OneNote, email, and several other services. Each Smart Title icon on the page can point to one of several destinations, so a filled page can land in a client folder, a shared team drive, or your own archive without manual sorting afterward.
Smart Tags work alongside Smart Titles to label a page with a category before it's even scanned. A consultant might tag one page as a client name and another as an internal task list, then let the app split them into separate folders automatically on scan, instead of renaming files by hand later.
For a professional who takes notes across several projects, that routing is the real value of the system. The pages themselves are just reusable paper. The Smart Title and Smart Tag layer is what turns a stack of handwritten pages into an organized, searchable digital record that a plain paper notebook can't produce on its own.
Which Rocketbook Core Size and Color Should You Get
Rocketbook sells the Core in two sizes: this Letter version at 8.5 by 11 inches, and a smaller Executive version at 6 by 8.8 inches. Both use the same paper stock, the same FriXion pen system, the same Smart Title and Smart Tag layout, and the same app. Size is the only real decision to make, and it comes down to where you write and what you write.
Letter size gives you a full sheet to write on, close to a standard notepad or a printed document. That matters if you sketch diagrams, take dense meeting notes, draft an outline that needs room to branch, or want a page that reads clearly once it's scanned and shared as a PDF with a client or a teammate. It sits flat on a desk the way a legal pad does, which makes it the better fit for anyone working mostly at a desk or in a conference room.
Executive is built for a jacket pocket, a small bag, or a commute. That portability comes at the cost of writing space. Long-form notes, wide diagrams, or anything with more than a few lines per thought get cramped fast on a 6 by 8.8 inch page. If your notes are short lists, quick reminders, or single ideas jotted between meetings, the smaller page is plenty and easier to carry.
Color is a cover choice only. It has no effect on the paper, the pen, or the app, so pick whichever shade you'd actually want sitting on a desk. If Green isn't it, the same Letter-size notebook is also sold in Teal, and the Executive size is sold in Gray. Both sibling pages cover the same Core system in more detail for their specific size and color.
What to Know Before You Buy
The Core only comes with one FriXion pen. Once it runs dry, you need a compatible refill or a new FriXion pen, since ordinary ballpoint or gel ink won't erase off the page. Budget for that as an ongoing, small cost of owning the notebook, not a one-time purchase.
The grid layout is fixed in this listing. There's no lined or blank page option here, so if you prefer ruled lines for dense writing, the grid dots are what you get. Most people adjust to writing on a grid quickly, but it's worth knowing before the notebook arrives, not after.
Wiping a page clean takes an extra step compared to a disposable notebook: scan first, then wipe. That's a habit to build. Skip the scan and the notes are gone once you wipe the page, and there's no undo once the ink is off the paper.
Because every page cycles back into use, the notebook depends on the app working correctly every time. If the scan fails to upload before a page gets wiped, that page of notes is gone, so treat the scan step as mandatory, not optional.
Build Quality and the Sustainability Angle
The cover on this version is described as scratch-resistant, and the notebook uses spiral binding rather than a glued spine, so pages lie flat when it's open on a desk. That's a small detail, but it matters for anyone writing while holding the notebook in one hand during a call.
The bigger pitch is reuse itself. A standard spiral notebook gets thrown away once it's full, and a new one gets bought. The Core's pages are designed to be written on and wiped clean repeatedly, so one notebook can replace a stack of paper notebooks over time instead of adding to it.
That's a genuine reduction in paper waste for anyone who fills notebooks regularly, though it only pays off if you actually keep using the same notebook instead of buying a new color every few months out of habit.
Rocketbook Core vs the Traditional Notebooks Ranked Nearby
Several of the notebooks selling alongside the Core in this category are ordinary paper spiral notebooks: hardcover journals with tabs, wide-ruled pads, and numbered-page planners. They're simpler and need no app, no pen replacement, and no phone charged and nearby to be useful.
What they don't do is scan, tag, or route notes to a cloud folder. Every page you fill is permanent, and the notebook itself is the only copy, which means losing the notebook means losing the notes. For a professional who wants a searchable digital record of handwritten notes, that's the gap the Core is built to close.
If you mainly want a nice place to write and don't care about a digital copy, one of the traditional paper notebooks in this category will cost less and ask nothing of you beyond a pen. If losing a notebook would mean losing real work, the Core's cloud backup is the reason to pay more for the same basic writing experience.

Frequently Asked Questions
- It measures 8.5 by 11 inches, the same footprint as a standard notepad or printer page. Rocketbook also sells a smaller Executive size at 6 by 8.8 inches, which uses the same paper and pen system in a more pocketable form.
- No. The reuse system depends on Pilot FriXion ink, which responds to heat and friction so it wipes off with a damp cloth. A pen with regular ink will write on the page but won't erase, so it defeats the entire point of a reusable notebook.
- Scan the page first with the Rocketbook app, then wipe it with a damp microfiber cloth or paper towel. The FriXion ink lifts off, leaving the page ready to write on again. Skipping the scan step before wiping means the notes are simply gone.
- The app can send scanned pages to Google Drive, Dropbox, OneNote, email, and several other destinations through Smart Title icons printed at the bottom of each page. Smart Tags can further label a page's category before it's scanned, so pages sort themselves without manual renaming.
- Get Letter if you write dense meeting notes, diagrams, or anything close to a full page and mostly write at a desk. Get Executive if you want the notebook to fit in a jacket pocket or small bag and you write in shorter bursts throughout the day.
