Interactive whiteboard software for Windows, Android, macOS and iPad. It starts in under two seconds, ink appears in under twenty milliseconds, and you erase by wiping the board with your hand.
Every claim below is measurable and checkable. That is the point.
Pressure-variable strokes that follow the nib in under 20 ms. Marker, highlighter and a non-persistent laser pointer, with a teacher-configurable palette.
Wipe the board with your hand, exactly the way a physical board works. No tool switch, no menu — the core differentiator, on by default.
Pan and zoom a tiled canvas, add, duplicate and reorder pages, lasso and transform anything. Undo never runs out below 200 steps, per page.
Ruler that ink snaps to, spotlight, screen shade, timers and a name picker — plus lazy-loaded subject packs for maths, chemistry, physics and language.
Bring in PDFs, slide decks and images. Send out clean PDF, per-page PNG, or the open .akb lesson file — losslessly, so your work stays yours.
Every core function runs with no account and no internet connection. The network is optional; the board is not.
Journal-based autosave, crash recovery to the last stroke, and session restore on relaunch. A dropped panel does not cost a lesson.
Annotate straight over anything on screen — a transparent, always-on-top layer with a click-through toggle. MSI install, MDM-deployable for IT.
Several people write at once, each with their own tool. Two-finger pan, pinch zoom, palm-swipe erase — the gestures a panel is expected to have.
A board should work the moment you walk into the room — not after a login, an update, and a spinning cloud icon. Akriva Board is offline-first, free to use, and saves to a file format you can read without us.
.akb format is documented; any software can read your lessons.Free, offline, and yours. Pick your device — Akriva Board installs from the browser and runs like a native app, full-screen and offline. No store, no account, no download wait.
Rather not install? Just open it in your browser → — it still works fully offline once loaded.
Akriva Board is in active development; you're installing an early-access build. Pilot institutes can request managed rollout at contact@merethion.com.
