How to Put Notes on a TI-84 Plus CE
You have a PDF study guide. You have a TI-84. You want to bring them together. Here's how that actually works, and why most of the methods you'll find online are painful.
The usual way sucks
If you've ever tried to get notes onto a graphing calculator, you probably ran into the same wall everyone hits. The TI-84 Plus CE has a tiny built-in text editor. You can technically type out notes there, but you're typing one letter at a time on a keypad designed for numbers. It's slow, error-prone, and if you have more than a page of material, you'll lose your mind before you finish.
Some people write TI-BASIC programs and paste text into the code line by line. That gets the text onto the calculator, sure. But you end up with a wall of characters with no way to search, no way to scroll smoothly, and a file size limit that cuts you off after a few hundred words.
The manual approach
- Type every letter by hand
- No search functionality
- Tiny file size limits
- Takes hours for long docs
- One mistake and you retype
With CiNotes
- Upload a PDF, done in minutes
- Full keyword search built in
- Handles hundreds of pages
- Content extracted automatically
- Scroll, jump, pick up where you left off
How CiNotes works
CiNotes takes your PDF study guides, class notes, or review sheets and turns them into compressed data files that run natively on your TI-84 Plus CE. The whole thing takes about five minutes from upload to calculator.
You upload your PDF to cinotes.com, enter your calculator's 10-digit Calculator ID, and check out. We email you a zip file with everything you need, plus a 6-digit setup code for your specific calculator.
Transfer the files over USB using the free TI Connect CE software, run the program, enter your setup code, and your notes are right there.
Once your order is delivered, every file you uploaded and everything we generated gets deleted from our servers. Your PDFs, your notes, the processed output, all of it. Zero data retention. Nothing sticks around after delivery.
Already got CiNotes files from a friend? You can add your own calculator at cinotes.com/setup instead of placing a full new order. We verify the existing PDF bundle and give you a setup code for your calculator instantly.
What it looks like on your calculator
When you open the program, you get a clean menu with three options. Search for a specific topic, browse everything, or jump back to wherever you were last time.
Search is where it gets useful. Type a keyword and CiNotes instantly pulls up every note that mentions it. Your search term gets highlighted so you can scan through results fast.

The UP and DOWN arrows scroll through the note. LEFT and RIGHT jump between matching notes. ENTER hops to the next highlighted keyword within a note so you don't have to scroll around looking for it. When you press CLEAR to go back to the menu, your exact position is saved. Next time you open the program and hit 3, you're right where you left off.
What you get
PDF processing
Upload any PDF. Our servers read your document, identify the structure (test banks, study guides, free response, raw notes), and extract the content automatically.
Keyword search
Bloom-filter indexed search across every note. Type a few letters and get instant results. Matches are highlighted in the viewer so you find what you need immediately.
Session resume
Close the program whenever you want. Next time you open it, your scroll position, search query, and current note are all exactly where you left them.
Works offline
Everything runs locally on the calculator. No WiFi, no phone, no internet connection. The files are on the device and they stay there.
What kind of documents work?
CiNotes handles three types of content. When you upload a PDF, our servers analyze it and figure out which type it is automatically.
Structured test banks (MCQ) are your typical multiple-choice question sets. Practice tests, exam review packets, question banks from textbook publishers. CiNotes extracts each question with its answer choices and organizes them as individual notes you can search and browse.
Free response and rubric documents (FRQ) cover essay-style questions, worked solutions, scoring rubrics, and AP-style prompts. Same idea, different formatting engine so the longer-form content stays readable on the small screen.
Unstructured notes is the catch-all for things like handwritten lecture notes (scanned to PDF), study guides, chapter summaries, formula sheets. Anything that doesn't follow a clean question-answer format. CiNotes breaks it into scrollable chunks and still gives you search across everything.
You can also type or paste short text directly on the website if you don't have a PDF. Text blocks under 300 words are free.
How much does it cost?
$5 base fee covers your first 10 pages. After that it's 10 cents per page up to 50 pages, then 5 cents per page beyond that. A 30-page study guide runs about $7. A 100-page review packet is around $12.50. No subscriptions, no recurring charges. You pay once, transfer the files, and they're yours.

Which calculators work with CiNotes?
The TI-84 Plus CE and TI-84 Plus CE Python Edition. It won't work on the older TI-84 Plus (the non-CE model) or TI-83.
How do I find my Calculator ID?
You'll need to download our quick Calculator ID checker program and send it to your calculator. Once you run it, it prints your 10-digit Calculator ID on the screen. The full instructions and download links are available when you click "How do I find my Calculator ID?" on the checkout page.
Can I use the same files on multiple calculators?
Each set of files is paired with one calculator's ID. If you already have an existing PDF bundle from a friend or study group, you can use cinotes.com/setup to add your own calculator without reprocessing the whole bundle. The add-calculator price depends on the original bundle size.
What if my PDF doesn't process correctly?
Email [email protected] and we'll take a look. Some heavily image-based or handwritten PDFs are harder to extract, but we can usually work something out.
Does anything get stored after processing?
No. All uploaded files and processed data are deleted from our servers once your order is delivered. Zero data retention.
Can I add more notes later?
Each order produces a standalone set of calculator files. If you want to add more content, you'd place a new order with the additional PDFs. The new files replace the old ones on your calculator.
