Most tutors juggle 2 tools during a lesson. Functra replaces both.

One tab. Everything in one place.

How a lesson works

From opening the board to sharing the notes — in three steps.

Open a board & invite

Create a board and share the link. Your student joins in seconds — no account, no download, no friction. They see your board live the moment they open it.

Teach, solve & graph

Write on the canvas as you explain. Open Graph Studio, type any equation, and drop the resulting graph right onto the board. Roots, tangents, and key points — visible to your student instantly. Advanced analysis tabs are marked BETA.

Export & share

Export every page as a crisp PDF, or add the board to a student's page — shared boards, notes, assignments, and homework photos in one link.

Every tool a tutor actually needs.

Graph Studio

Type any equation — x²−5x+6, sin(x)/x, whatever you're teaching. Get instant graphs with roots and tangents. Explore domain, extrema, and more in analysis tabs (marked BETA). Place any graph on your board as an image. No external calculator. No LaTeX required.

Student Pages

Give each student a personal link — no account needed. Share lesson boards, post notes and assignments, and collect homework photos via QR. Everything in one place, between sessions.

Live Collaboration

Students join via link — no sign-up needed. Cursors sync in real time (Class Mode shows only your cursor in groups). Invite with a single URL, start teaching immediately.

Class Mode & Board Lock

In Class Mode, students see only your cursor — no distractions. Lock the board entirely when you need their full attention. Full control of your session.

High-Res PDF Export

Export the current page or every page at once as a print-ready PDF. Students get complete lesson notes — graphs included — with one click.

Smart Board Organization

Tag boards by student or subject (e.g. “Algebra”, “A-Level”). Search across all boards instantly and pick up right where you left off.

Simple, transparent pricing.

Start free with one board. No credit card required. Upgrade to Pro when you need more.
