About GapFiller
What is GapFiller?
GapFiller is a personal workspace for teachers. You plan lessons on a calendar, build curricula, attach materials, assign homework, schedule exams, and keep a teaching archive that stays yours across schools and years.
See What is GapFiller and how does it work?.
Is GapFiller a school platform?
No. It does not replace registers or tools your school requires. It is built around your planning and materials — even if you change school or teach in more than one place. Longer read: personal vs school-wide tools and GapFiller vs school LMS.
Who can use it?
Anyone who teaches: school, university, tutoring, language courses, private lessons or training. If you teach, you can organise your work in GapFiller.
Do I need to download an app?
No. GapFiller works in the browser on computer, tablet or phone.
Plans and billing
Is there a free trial?
No. Watch the product demo on the website before you buy, then choose a plan at signup. There is a 15-day money-back guarantee.
What plans are available?
Standard, Pro and Lifetime.
| Plan | In short |
|---|---|
| Standard | Everyday planning: up to 2 schools, unlimited subjects, up to 5 curricula, 500MB storage |
| Pro | Unlimited schools and curricula, 5GB storage, plus Google Drive and OneDrive |
| Lifetime | Pay once — Pro-level access forever, no recurring subscription |
Details: Manage your subscription and Create your account.
What's the difference between Standard and Pro?
Standard includes up to 2 schools, unlimited subjects, up to 5 curricula, and 500MB of file storage. Pro removes the school, curriculum and storage caps (5GB) and adds Google Drive & Microsoft OneDrive. Lifetime includes all Pro features forever.
Why choose Lifetime?
Your archive grows more valuable every school year. Lifetime is a one-time payment so you keep building without a recurring bill. Billing changes are not managed in the Stripe portal for Lifetime.
Can I cancel or change billing?
Yes for Standard and Pro: manage payment method, invoices, plan/period changes and cancellation from Profile → Manage billing in Stripe. You usually keep access until the end of the current billing period. Lifetime has no subscription to cancel.
Are payments and data safe?
Payments go through Stripe — GapFiller does not store your card on its servers. Your lessons and files are stored with standard security practices; your workspace belongs to you.
Getting started
How long does setup take?
A few minutes: add school, subjects, grades and a timetable, then start planning. Follow Create your account, then the onboarding walkthrough.
Can I use more than one school?
Yes. Standard includes up to 2 schools and unlimited subjects. Pro and Lifetime have unlimited schools. If Create New is disabled on the Schools tab, you are at the Standard cap — upgrade from Subscription, or delete a school to free a slot.
How do I change the language?
GapFiller is available entirely in English, Italian and Spanish (more languages coming later). Profile → Select language → EN, IT or ES. Guide: Change language and preferences.
Calendar, curriculum and teaching
How do lessons get on my calendar?
Create them one by one, or set a timetable and generate lessons for a date range. Holidays can be excluded via the academic calendar.
What is a curriculum?
A reusable teaching plan: a sequence of topics with plans, materials and todos. You can create, import from past lessons, and apply topics onto calendar lessons. Standard includes up to 5 curricula — creating, importing and duplicating all count. Pro and Lifetime have no curriculum cap.
How do homework and exams work?
Homework is assigned from one lesson and due on another. Exams are lessons with type Exam, linked to a grading sheet. You can also add ad-hoc assessments (oral, homework marks) from the Exams page, then follow averages in the Gradebook.
Guides: Assign and track homework, Schedule and manage exams, Use the Exams page, Enter grades, Class gradebook.
Can I keep a class roster and enter marks?
Yes. Add student names on each class under School Settings → Grades, then grade from the sheet or gradebook. Guide: Set up your class roster.
Can I reuse work next year?
Yes. Duplicate or adapt curricula, keep materials in Files, and re-apply topics to a new calendar. That archive is a core reason to use GapFiller. See also how teachers keep an archive across school changes and a planner that follows you.
Files and cloud storage
Can I upload materials?
Yes — from Files or from a lesson’s Materials tab. Guide: Upload and organise materials.
What happens when I reach 500MB?
On Standard, new uploads stop at 500MB — from Files and from a lesson. Files you already uploaded stay in the library: preview, download, attach and delete still work. Delete a file to free space, or upgrade to Pro or Lifetime for 5GB.
Can I connect Google Drive or OneDrive?
Yes on Pro and Lifetime. On Standard the Connect button is not shown; you get an upgrade prompt, and a connection is refused. Guide: Connect Google Drive and OneDrive. Disconnecting does not delete files already imported into GapFiller.
Tools and support
What teacher tools are included?
Grade Calculator, Evaluation Grids and Gap Fill Generator — available from Teacher Tools in the sidebar.
How do I contact support?
