MarrowStudio pinboard and manuscript loom for multi-modal research
Start a studio board

Pin voice memos, sketches, and book clippings to one wall, then read them as a finished draft.

Research begins as a messy collage of photos, audio interviews, and torn quotes. Marrow lets you arrange raw materials spatially on a canvas and flip into a structured linear essay with a single click.

Project board: Daylight geometry in industrial workshops

Toggle checkboxes on any clipping to include or exclude it from the compiled manuscript, then switch views on the right.

Book excerptPin #1

Daylight factor in North European weavers’ lofts

Tall ribbon windows flush with the ceiling plane bounce diffuse sky light deep across the timber floor, eliminating harsh contrast around the loom threads.

Steen Eiler Rasmussen, Experiencing Architecture (1959), p. 194
Voice memoPin #2

Site walk at the Zurich sawtooth foundry

“Notice how the north-facing glass panes slope at sixty degrees. Even at noon in July, zero direct sun hits the drafting tables, yet our light meter reads 650 lux across every bay.”

Field diagramPin #3

Section geometry of a 60° north-light monitor roof

60° North glazing

Reflective lime-painted sloped baffle redirects 74% of zenith sky luminance downward into a 9-meter structural bay.

Sketchbook VII, Sheet 14
Archive ledgerPin #4

Glazing maintenance logs from the 1912 municipal printworks

Cast wired-glass panels on 1.2-meter mullions survived eighty winters with under two percent pane replacement.

City Building Archive, Box 44, Folder 3

Every medium is a first-class note on the same table

You shouldn’t need one app for PDF highlights, another for voice memos, and a third for spatial moodboards.

Field audio & transcripts

Whisper-accurate local transcription linked to waveform timestamps

Record a walk-through on your phone. Marrow transcribes it offline on your machine and lets you highlight any sentence to create a playable audio clipping on your board.

PDFs & archival scans

Crop a figure from a 400-page monograph and keep its page number

Drag any region of a PDF onto your canvas. Clicking the clipping years later opens the original source page at the exact paragraph you highlighted.

Two-way outline sync

Rearrange cards on the wall to reorder paragraphs in your draft

Spatial arrangement and linear writing are two views of the same underlying files. Edit a sentence in the manuscript and the card on your studio wall updates immediately.
