Scale 1:1 Live Sync · Archival Cotton Vellum 240gsm · Latency: <14ms
No generic corporate decks. Raw intuition, crisp ink rules, and tactile thought.
The tactile canvas where minds collide in real time.
Archival cotton vellum, carbon sumi ink, and zero-latency CRDT state convergence. Built for engineering architects, product planners, and designers who demand tactile craft.
No locked screens.
No merge conflict dialogs.
Traditional whiteboards lock layers or overwrite edits when networks jitter. MergeCanvas treats canvas state as a Conflict-Free Replicated Data Type (CRDT) with deterministic convergence.
Local-First Mutation
Your pencil, shape, or sticky mutation writes immediately to the local Yjs document at 60fps.
Delta Encoding
Only binary diffs are serialized, keeping packet sizes minuscule and bandwidth efficient.
Peer Mesh Broadcast
WebSocket relays forward binary updates across connected participants in milliseconds.
Formal Convergence
Mathematically proven merge algorithms guarantee all users arrive at the identical state.
The Tactile Workshop Manifesto
Physical Studio Craft
The interface mirrors authentic studio tools. Canvases emulate heavy cotton vellum and technical graph paper, while interface containers feel like dense chipboard and draftsman rulers.
Ink & Vellum Contrast
Deep, carbon-rich ink rules interact with warm paper fibers. Information is bounded by deliberate, crisp strokes rather than vague shadow drops.
Asymmetric Human Precision
The layout balances mathematical drafting grids with slight organic misalignments—subtle angular offsets, tape swatches, and hand-annotated accents.
