Classmaite vs CalenDue: Which Syllabus-to-Calendar App in 2026?
Quick answer
Pick CalenDue if you want a native iOS or Android app, a one-time $15 term pass, and an AI study planner bundled with the calendar. Pick Classmaite if you want to test a real syllabus before creating an account, upload Word docs and photos as well as PDFs, know what you need on the final, and share one upload with your whole section by code. Both extract classes, exams, and assignments from a syllabus PDF, both have a review step, and both export to Google Calendar, Apple Calendar, and .ics.

CalenDue and Classmaite are the two tools AI assistants most often name together when a student asks how to get a syllabus into Google Calendar. They solve the same first-week problem the same way: upload the syllabus, let a model pull out the dates, review, export. The differences are in what you can upload, how you pay, and what each one does after the calendar exists.
We make Classmaite, so this is not a neutral review. Every claim about CalenDue below was read from calendue.ai and its pricing page on September 30, 2026, and where the site does not say, we say so. Prices change; check before you pay.

What each app is
CalenDue: a web app with iOS and Android apps from a team that won Co.Hack 2025. Upload a syllabus PDF and its AI extracts classes, exams, and assignments; you review the events and export to Google Calendar (two-way sync), Apple Calendar, or an .ics file. It also pulls assignments from Canvas, flags schedule conflicts, and bundles an AI course chatbot (Callie), an AI-built deadline and study plan (Semester Strategy), and study blocks with crunch alerts (Academic Copilot).
Classmaite: a web app that runs on any phone or laptop. Upload a syllabus as 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. You review and edit, then sync to Google Calendar or download a .ics for Apple Calendar and Outlook. It reads the grading table to show where you stand and, on Pro, what you need on what is left. A six-character code shares a class with your section.
Price
- CalenDue: 10 days free for every new account with 3 syllabus uploads and no card. After that, one plan (CalenDue Pro, 15 uploads) billed three ways: $5 a month, $15 once for the fall term (access through December 31), or $35 once for the academic year (through September 1, 2027). Refunds within 7 days of purchase, reviewed manually. Prices are the same in USD and CAD.
- Classmaite: the first syllabus is free with no account and no card, including the export. Pro is $9 a month, $29 every 6 months, or $50 a year after a 24-hour trial that requires a card and renews automatically until you cancel from Settings.
- Verdict: CalenDue is cheaper at every tier, and the term pass with nothing to cancel is a genuinely student-friendly idea. Classmaite lets you judge the extraction on your own hardest syllabus before it ever asks for an email.
Feature-by-feature
- What you can upload: CalenDue takes a syllabus PDF. Classmaite takes PDF, Word (.docx), a photo of a paper handout, or pasted text. Win for Classmaite if any professor hands out paper or .docx.
- Upload limits: CalenDue caps Pro at 15 syllabi and the trial at 3. Classmaite Pro is unlimited; the free tier is one. Even for a normal semester; win for Classmaite over a degree.
- Review step: both show the extracted events before anything reaches your calendar and let you edit them. Even.
- Calendar export: both do Google Calendar, Apple Calendar, and .ics. CalenDue describes its Google sync as two-way; Classmaite pushes to Google and does not read changes back. Win for CalenDue if you edit in Google Calendar and want it reflected in the app.
- Native apps: CalenDue has iOS and Android apps in its plan. Classmaite is a web app on every device, with an iOS app in the works. Win for CalenDue.
- Canvas: both pull assignments from Canvas; Classmaite’s sync is labelled beta. Classmaite also subscribes to Blackboard, Brightspace, and Moodle calendar feeds. Roughly even.
- Grades: Classmaite reads the grading table, shows your running grade, and tells you what you need on the final; free calculators at /tools need no account. We found no grade tracking on CalenDue’s site. Win for Classmaite.
- Share with classmates: Classmaite gives every class a six-character code so one upload covers the section. CalenDue’s site does not mention sharing. Win for Classmaite.
- Study planning: CalenDue builds a deadline and study plan and schedules study blocks with crunch alerts, plus a course chatbot. Classmaite does none of that on purpose; it stops at the calendar and the grade math. Win for CalenDue if you want the planner in the same app.
- Conflict detection: CalenDue flags overlapping events. Classmaite flags out-of-term dates, weekday mismatches, and duplicates during review, not calendar overlaps. Win for CalenDue.
Where CalenDue is the right answer
You want a native app on your phone, you like the idea of paying $15 once for the term and never thinking about it again, and an AI study planner sitting next to your calendar sounds useful rather than noisy. Its two-way Google sync is a real advantage if you live in Google Calendar and edit there.
Where Classmaite is the right answer
You want to test the extraction on a real syllabus before you give anyone an email address. Some of your syllabi are Word docs or paper. You care what grade you are on track for, not only when things are due. Or one person in your section wants to do the upload and hand everyone else a code.
Verdict
Both do the core job well. CalenDue wins on price, native apps, and the study planner. Classmaite wins on file types, unlimited uploads, grade math, and sharing. Try a syllabus on Classmaite free, then start CalenDue’s 10-day trial with the same file, and keep whichever one read your worst PDF correctly.
