Free online whiteboard for tutoring: what each free plan really allows

Almost every tutoring whiteboard says "free". Most mean three boards, a few minutes of collaboration, or a trial that ends. This page lists what each vendor's own page says a free plan gives you, checked on November 5, 2026, so you can pick the limit that hurts you least. A ready lesson board is below.

The short answer

  • No free plan here is unlimited. Zoom Whiteboard, Miro and Ziteboard give you 3 boards, Explain Everything 3 projects and 15 minutes of collaboration, Bitpaper only lets you join, and Lessonspace has no free plan. Instaboard gives you 5 boards in your list and 150 items across your account; pen strokes don't count.
  • Check two things before you pick: can your student write (most tools want a sign-in, and some want a paid add-on for guests), and does the free call last a lesson.
  • If you teach math, WooWhiteboard's free equation editor and graphing beat what we have. If you teach by hand with worksheets and want the call on the board, read on.

What each free plan allows (checked November 5, 2026)

Read from each vendor's own page on November 5, 2026 (links in the sources). Explain Everything's free and $69 rows are listed on its Plans for Education tab; we did not read its individual and commercial plans. Prices exclude tax. Instaboard figures are from our own plans.

Which limit will bite you first

  • Number of boards. A tutor with six regular students runs into a cap of 3 (Zoom, Miro, Ziteboard) or 5 (Instaboard) in the first month. Reusing one board per student and wiping it works on any of them. On Instaboard pen strokes don't count toward the 150 items, so ink-heavy boards go a long way.
  • Collaboration time. Explain Everything's free plan stops collaboration at 15 minutes. If your lesson is an hour, that rules it out.
  • Who can write. Instaboard: anyone with the link can view, writing needs a free sign-in with Google, Apple or email. Zoom: depends on your plan and your admin's settings. Ziteboard: guests without an account need a paid add-on. Miro: visitor editing is Starter. Bitpaper: your student joins on the free plan, you pay to create.
  • The call. A free whiteboard still needs a way to talk. Free Zoom meetings end at 40 minutes; Google Meet's own page says free one-to-one calls can run up to 24 hours. Instaboard's built-in free calls run up to 60 minutes per call, with a warning 10 minutes before the end; calls need a free sign-in, there is no recording, and Pro has no limit. More: the Zoom 40-minute limit for tutors and a whiteboard for Google Meet.

Where the others are better

  • WooWhiteboard for math. A built-in equation editor, function graphing and Wolfram Alpha, free. We have equation cards (typeset from a math keyboard), a Desmos card that needs internet, and ink. No plotter, no algebra engine. See an online whiteboard for math.
  • Zoom for annotation. Zoom lets presenters and viewers draw on whatever is on screen (Zoom's annotation article, updated July 7, 2026).
  • Google Meet for long free one-to-one calls. Up to 24 hours on Google's page, against our 60 minutes per call.
  • Lessonspace for recordings. It stores recorded sessions for 90 days on every plan. We don't record.
  • Excalidraw for diagrams, free with unlimited collaborators by link, if you never need worksheets or a call.

When Instaboard is the free one to pick

  • You write by hand (pen, Apple Pencil, a drawing tablet) and your student answers on the same page.
  • You bring a worksheet or a photo of homework and mark it up.
  • You want the call on the board, or to keep Zoom or Meet and put the board link in the chat.
  • You want the board to be there next week at the same link.

What Instaboard's free plan doesn't do

  • Your student needs a free sign-in to write.
  • 5 boards in your list, and boards others send you count toward them. Past 5 you can't create more until you remove one or go Pro.
  • No handwriting recognition, no plotter or algebra engine, no recording, no class mode and no scheduling.
  • The eraser removes whole strokes; undo is the quickest way to fix the last thing you wrote.
  • 3 images and 1 file per board on the free plan.

Questions

What is the best free online whiteboard for tutoring?

It depends on the limit that matters to you. For math with equations and graphs, WooWhiteboard's free tools are stronger than ours. For handwriting, worksheets and a call on the same board, Instaboard's free plan fits. If you only draw diagrams, Excalidraw is free with unlimited collaborators by link.

Is there a tutoring whiteboard with no limits on the free plan?

Not among the ones above. Each one caps boards, projects, collaboration time or who can create. The cap that matters differs by how you teach, which is why the table lists them side by side.

Can my student write on the board without an account?

On Instaboard, anyone with the link can view, and writing needs a free sign-in with Google, Apple or email. Other tools differ: Zoom depends on your plan and admin settings, Ziteboard guests need a paid add-on, and Miro's visitor editing is listed under Starter.

How long can a free call on Instaboard last?

Free calls run up to 60 minutes per call, with a warning 10 minutes before the end. Calls need a free sign-in and there is no recording. Pro calls have no limit. You can also keep Zoom or Google Meet and put the board link in the chat.

When do I need to pay?

When you outgrow 5 boards, or want no image limit or no call limit. Pro is $5 a month billed yearly ($59.99 a year), or $7.99 monthly.
