Side-by-Side Document & Canvas Balance
Read PDFs with exact typography and high-speed rendering on the left, while manipulating an unconstrained 2D infinite workspace on the right. An interactive resizable splitter allows you to adjust screen real estate dynamically, with full responsive tab switching on mobile devices.
- Infinite 2D pan and zoom from 0.1x to 3.0x
- Semantic zoom Level-of-Detail (LOD) for dense card maps
- Grid snapping and dynamic card clustering

#P1-C1Pixel-Precise Coordinate Pinning
Snip any paragraph, formula, table, or chart directly from a PDF. LoomSphere establishes a live coordinate link with color-matched badges and cubic bezier connector lines. Clicking a pin badge on your canvas immediately scrolls the document reader to the exact pixel coordinate on that page.
- Color-coded badge markers: blue, green, amber, purple, rose
- Dynamic bezier connector curves that adapt on pan and zoom
- Snip tool with automated card creation on the canvas

Clicking either badge synchronizes both views instantly.
Natural Stylus, Pressure & Palm Rejection
Designed ground-up for Apple Pencil on iPad and S-Pen on tablets. Experience fluid vector ink that responds to pressure variation, automatic palm rejection, translucent highlighter blending, and card-bound drawings that move with your canvas notes.
- Card-bound inking: doodle notes stay locked to their cards
- High-speed SVG vector strokes with zero stroke loss on zoom
- Seamless pen, highlighter, eraser, and selection modes
Document Squeezing & Accordion View
Why scroll past 80 pages of irrelevant appendices? LoomSphere lets you fold non-consecutive page ranges like an accordion. Compare a paragraph on page 4 directly next to a clause on page 188 without endless scrolling or jumping.
- Highlight Pinching: collapse everything except annotated pages
- Expand/collapse page clusters with a single tap
- Zero page re-rendering lag during squeeze and expand
Multi-Format Synthesis Studio
Once your synthesis is complete, export high-resolution deliverables in any format. Generate side-by-side synthesis PDFs where document pages appear alongside your spatial canvas notes, export high-res visual PNG snapshots, or save self-contained encrypted .loomdoc containers.
- Side-by-side synthesis PDF generator with coordinate badges
- Encrypted .loomdoc file packages with password protection
- Structured Markdown outlines ready for Obsidian, Notion, or Roam

Infinite 2D Canvas Engine
Pan and zoom from 0.1x to 3.0x with smooth inertia. Level-of-Detail (LOD) clustering ensures thousands of notes render smoothly with zero stutter.
Bidirectional Coordinate Pins
Snip excerpts directly into canvas cards. Clicking a pin badge jumps straight to the exact page millimeter, eliminating lost citations.
Apple Pencil Pressure Engine
High-precision stylus input with palm rejection and card-bound inking. Doodles, highlights, and annotations stay anchored to cards.
Accordion Page Squeezing
Collapse non-consecutive page ranges to eliminate clutter. Compare distant clauses side by side with zero cognitive overload.
Multi-Document Synthesis
Simultaneously view and cross-reference multiple PDFs, Word documents, and spreadsheets on a unified 2D knowledge workspace.
100% Local-First & Private
Full IndexedDB persistence via LocalForage. Your confidential documents, contracts, and notes never leave your machine unless you sync.
Designed for Your Workflow
Academic Researchers
Synthesize 20+ arXiv papers, connect citations, extract formulas onto cards, and outline literature reviews.
