Classmaite vs SyllabusSpy: AI Parsing or Rules, Free or Paid?
Quick answer
Pick SyllabusSpy if your syllabus is a clean PDF, you want it converted free with nothing uploaded anywhere, and a subscription calendar link that updates when you fix a date. Pick Classmaite if your syllabus is a Word doc, a photo, or an awkward layout an AI reads better, or you want the grading table read, a what-do-I-need-on-the-final answer, and a share code for your section. Both are free to try without an account and both export to Google, Apple, and Outlook.

SyllabusSpy and Classmaite land on the same review-table idea from opposite directions. SyllabusSpy reads the PDF with hand-built rules inside your browser, so it is instant, free, and never sends the file anywhere. Classmaite sends the document to an AI model, which costs something per parse and handles messier documents. Which is right depends mostly on what your syllabus looks like.
We make Classmaite, so read this with that in mind. Every claim about SyllabusSpy was read from syllabusspy.com on September 30, 2026. Its own page is unusually candid about the trade-off it makes, and we have tried to be equally candid about ours.

What each tool is
SyllabusSpy: a free web tool with no account and no card. Drop in a syllabus PDF (or paste the schedule as text, or connect Canvas) and a rules-based parser, running in your browser, pulls out due dates, exams, quizzes, readings, labs, and days off in about a second. Every entry shows the line of the syllabus it came from. You then subscribe your calendar to a private link (Google, Outlook, Apple), download a .ics, or add single events. One link covers every class you add, and it can send an email the night before something is due. The PDF never leaves your device unless you choose to share it.
Classmaite: a web app that sends the document to an AI model. Upload a PDF, Word doc, photo, or pasted text and in about 30 seconds it extracts assignments, exams, readings, class meeting times, and the grading table, with the source quote for each item. You review and edit, then sync to Google Calendar or download a .ics. It shows where you stand in each class from the weights, and on Pro what you need on what is left. A code shares the class with your section.
Price
- SyllabusSpy: free, with no trial and no paid tier; its page says nothing is held back for an upgrade.
- Classmaite: the first syllabus is free with no account. Unlimited syllabi, grade targets, and Canvas sync are Pro at $9 a month, $29 per 6 months, or $50 a year after a 24-hour trial.
- Verdict: SyllabusSpy wins on price outright. Classmaite’s free tier covers one class; a full semester is paid.
Accuracy: rules vs a model
SyllabusSpy says it plainly: on a strangely laid-out document an AI would probably catch a row or two the rules miss, and in exchange the rules cannot invent a deadline that is not printed. It handles week-by-week tables, bulleted date lists, and the midterm mentioned in a paragraph, and it hands you a prompt to run the awkward ones through a model yourself.
Classmaite’s model reads the awkward ones directly, including photos of paper handouts and Word files, and it reads the grading table, which SyllabusSpy deliberately skips. The cost is that a model can misread, which is why Classmaite runs deterministic checks after extraction (dates outside the term, weekday mismatches, duplicates, low confidence) and flags them in the review list. Both tools put a review step between the parse and your calendar, and that step is where most of the difference stops mattering.
Feature-by-feature
- Uploads: SyllabusSpy takes PDF, pasted text, or Canvas. Classmaite takes PDF, Word, photo, pasted text, or Canvas. Win for Classmaite on Word and paper.
- Privacy: SyllabusSpy parses in the browser and the PDF stays on your device. Classmaite sends the document to a model to parse it and does not store a guest’s syllabus. Win for SyllabusSpy.
- Speed: SyllabusSpy is instant. Classmaite takes about 30 seconds. Win for SyllabusSpy.
- Source lines: both show where each date came from. Even.
- Calendar delivery: SyllabusSpy offers a subscription link that updates when you fix a date later, plus .ics and single-event add. Classmaite syncs directly to Google Calendar and exports .ics; a change after export means re-exporting. Win for SyllabusSpy on the subscription link.
- Times: both keep exam and class times when the syllabus states them and leave plain deadlines all-day. Even.
- Grades: Classmaite reads the weights and answers what you need on the final; SyllabusSpy skips grading tables by design. Win for Classmaite.
- Share with classmates: Classmaite has a class code. SyllabusSpy’s page does not mention sharing. Win for Classmaite.
- Reminders: SyllabusSpy can email you the night before. Classmaite relies on Google Calendar alerts on the web and phone notifications in its iOS app; it does not send reminder emails. Different, roughly even.
- LMS: both connect to Canvas; Classmaite also subscribes to Blackboard, Brightspace, and Moodle feeds. Slight win for Classmaite.
Where SyllabusSpy is the right answer
Your syllabi are ordinary PDFs with a schedule table, you do not want to pay, and you would rather the file never left your laptop. The subscription link is the best answer either tool has to a professor moving an exam in October.
Where Classmaite is the right answer
A professor handed out paper or a .docx. Your syllabus buries dates in prose an exact-match parser will miss. You want the grading table read so the calendar knows a 35% final matters more than a 2% quiz, and you want the number you need on that final. Or your section wants one upload and a code.
Verdict
Run your syllabus through both; neither asks for an account. If SyllabusSpy gets every row, use it and keep your money. If it misses the rows that matter, or your syllabus is not a PDF, Classmaite’s model and review step will get you there, and the grade math is the reason to stay.
Frequently asked questions
Is SyllabusSpy really free?
Its site says yes: no card, no per-semester fee, and no upgrade tier, as of September 30, 2026. Classmaite’s first syllabus is free; unlimited syllabi are Pro.
Does SyllabusSpy use AI?
No. It reads the PDF with rules in your browser and says so on its page, noting that an AI would likely catch a row or two more on odd layouts while the rules cannot invent a date. Classmaite uses an AI model with deterministic checks afterward.
Which one handles a photo of a syllabus?
Classmaite. SyllabusSpy takes a PDF or pasted text.
Which one keeps my calendar updated if a date changes later?
SyllabusSpy, through its subscription link: fix the date there and every subscribed calendar updates. With Classmaite you edit the class and re-export, or change the event in Google Calendar directly.
