Tools for Educators & Teachers
107 toolsTools for preparing lessons and running a class: handouts from PDFs, English and language teaching, marking written work, text-to-speech and captions, and support for learners with additional needs.
Handwriting from typed text
Turns typed text into a page written by hand: handwriting styles, ruled paper, transparent PNG and PDF. Also writes by hand into an existing PDF form.
Orchestration check
Reads a MusicXML or MIDI score and shows what the orchestra cannot play: notes out of range, no room to breathe, impossible harp chords.
Voice Boost for Video
Speech too quiet and music too loud? The player lifts voices and holds the background down while you watch — and saves the fixed video.
Mind map
Build a mind map from the keyboard, or paste a list and get a map. Share it as a link with no account; export PNG, PDF, Markdown, OPML.
Printable Puzzle Maker
Sudoku at 4×4, 6×6 and 9×9 with one verified solution and honest difficulty, plus word searches from your own list. Four to a page, PDF with answers.
Certificates and diplomas
Build an award document and print it — one, or a whole class at once.
AI prompt generator
Ready-made prompts for photos, chat, video and music, plus a builder that assembles your own prompt part by part and shows what is missing.
Schulte Tables
Find the numbers in order without moving your eyes from the center. A series of five grids gives you work efficiency, warm-up and stability.
Speed Reading Trainer
Read one word at a time with an eye anchor, in chunks or by sentence — and measure how many words per minute you actually read.
Earthquake simulator
See how hard a given magnitude shakes your city: intensity contours on a real map, a synthetic seismogram and building response. Runs in the browser.
Beaufort scale
Wind force in numbers: the full Beaufort table, the Saffir-Simpson categories, and what wind a hurricane would deliver to your city.
Visual Timer
A timer where the remaining time is a shape, not a number.
Labels & stickers
Build your own sheet of labels and print it so the ink lands inside the die cuts.
Country flags
An online tool for the flags of the world: filter by color, check the proportion and color codes, download PNG or SVG — or set the cloth waving in the wind.
Wall Newspaper
Build a printable wall newspaper for school holidays, classroom corners or birthdays — drop in photos, text and stickers, then print across A4 sheets.
Photo cropping without quality loss
Crop a photo by frame, ratio or exact pixels. JPEG is cut without re-encoding. Also: circle crop, print size in cm, tiles and a poster across A4.

Crop PDF
Trim white borders from a PDF. Auto-detect ink, set margins in mm/in/pt, preview live. Vector output, in the browser.
