Synapse is the smart note-taking and drawing app with AI at its core. Write like on paper, let the AI recognize your handwriting, solve math problems — and everything stays in sync across all your devices.
Synapse combines free-form drawing, structured notes and AI assistance in a single app. Instead of switching between five tools, you work in one place.
Load lecture scripts, worksheets or contracts as a background and write directly on top. Perfect for slide annotations, lecture notes and corrections.
Lasso your handwritten text → "Recognize" → done, typed text. Works even with messy handwriting, sketches and notes.
Write an equation, circle it, hit "Solve". Synapse shows you the step-by-step solution — perfect for school and university.
Ask the AI about your notes, get concepts explained, or request a summary. The AI sees your notebook context.
End-to-end cloud sync. Start a notebook on your tablet, continue on your desktop, read on your phone. Servers in Germany.
Plot functions, transfer functions, analyze Bode diagrams. Engineering tool and notebook in one.
Let the AI extract formulas from your sketches, instantly plot them as graphs, ask the chat assistant to explain. Synapse replaces four tools: notes app, calculator, plotter and study aid.
Working on a project and need something from another notebook? Open it as a second tab and switch with one click. No file searching, no context loss.
Synapse combines free-form drawing, AI assistance and structured notes — whether you write formulas at uni, sketch in a studio or plan concepts.
Lecture notes, math exercises, script annotation. Lasso-solve, AI explanations, function plotter — all in one notebook.
Sketches, moodboards, storyboards across any number of notebooks with all pen and drawing tools — synced across all devices.
Formula libraries, Bode diagrams, transfer functions plotted directly in the notebook. PDFs as background, AI chat for complex math problems.
