A character redesign rarely starts from nothing. It starts from an art director saying "keep the silhouette but read younger," which means the actual job is holding a dozen properties of the original design in mind — proportion, material, palette, the specific way the shoulders read — while changing one of them. That only works if the reference behind the original design is findable, not just remembered.
What a character library looks like after more than one project
Most character designers are not maintaining one tidy reference set; they are accumulating several, one per project, each with its own mix of anatomy studies, material photographs, costume references and existing-IP screenshots kept purely to match a studio's established style. It works fine while a project is live. It stops working the moment a sequel or a spin-off needs the same character's silhouette rules applied to someone new, and the only record of what those rules actually were is scattered across two-year-old project folders.
A material or a proportion, found by what it is
Placing turnarounds and their source material on one canvas keeps the
argument for a design visible rather than buried in a chat thread: this
shoulder shape came from this reference, this material reads this way under
this light. Because a .coii-canvas is pretty-printed JSON sitting in your
own folder, it diffs and version-controls the same as any other design file,
which a locked-format board from a hosted tool cannot do.

held up, and in:Costumes scopes a search to one folder without leaving the
rest of the library out of reach. A term the parser does not recognise
renders as free text rather than an error, so a half-remembered word from a
brief still returns something to narrow down from.
Anatomy, costume and material as three folders, one search
Character reference tends to split naturally into anatomy studies, costume
and prop photography, and material or texture references, and none of those
need merging into one folder to be searched together. Register all three as
part of the same workspace and tag:any:armoured reaches whichever one
actually carries the tag, whether that is a photo of real plate armour or a
turnaround drawn to match it.
Keeping an established design's rules reusable
A studio's established characters carry unwritten rules — this hero's
silhouette always reads triangular, this villain's palette never uses warm
tones — and those rules live in whoever remembers them unless the reference
behind them is tagged for the property it demonstrates rather than only for
the character it belongs to. Tagging by silhouette, palette and material as
well as by character name means tag:any:triangular-silhouette still returns
every design that follows the rule, long after the person who set it has
moved to a different project.
Rating what actually survived approval
Not every reference pulled during exploration ends up mattering, and a year
later it is rarely obvious which pieces actually shaped an approved design and
which were dead ends. Rating reference once a design is locked — four stars
for the material study that became the final armour finish, one star for an
exploration that went nowhere — turns rating:>=4 into a shortlist of what
actually worked, rather than a guess based on which images happen to be
remembered.
What happens to reference a client or studio sends directly
Not all character reference arrives through personal research — a client's brand guidelines, a licensor's approved model sheets, a studio's internal style bible sent as a batch of files. None of that needs special handling: drop it into the project folder already registered, and the watcher picks it up on its own, ready to tag the same as anything gathered independently. There is no import dialog to run for a handful of new files.
Building a personal style reference that survives a change of software
A character designer's own reference habits tend to outlast whichever package a given studio uses, and a library built entirely inside one tool's project format does not travel when the tool changes. Keeping anatomy studies, material photos and turnaround canvases as ordinary files in an ordinary folder means the personal library survives every software change it will ever see — registering the same folder again after switching packages costs one re-index, not a rebuild of years of collected reference.
Working across a personal Mac and a studio machine
Freelance and contract character designers often keep a personal reference archive at home and use a studio-issued machine during a job, and the two do not need to be one workspace. Register the personal archive on a personal Mac and, separately, a studio's shared reference drive on the studio machine — each builds its own local index, with nothing to sync and no account tying the two together. Licensing covers three Macs on one purchase, which in practice covers a home machine, a laptop and a studio seat.
Presenting a design review without building a separate deck
Design reviews run on being able to show the reference behind a choice, not
just the choice itself, and pulling that reference into a slide deck for
every review is a small project on its own. A .coii-canvas skips the
throwaway step: place the turnaround, the material photos and the anatomy
study that justify it on one board, present straight from it, and the file
stays in the project folder afterward as a record of the actual reasoning,
rather than a deck that gets deleted once the meeting ends.
Building a personal reference habit across more than one studio
A character designer's own research tends to outlast any single employer, and reference gathered for one studio's IP is not automatically useless the next time a different studio needs a similar property — a material study or an anatomy reference is reusable regardless of which characters it was first collected for, provided it was never tied to that studio's own asset management system in the first place. Keeping personal reference in ordinary folders, tagged by property rather than by employer, means a designer's own library keeps compounding across an entire career instead of resetting with every new contract.
Comparing this to a dedicated moodboard tool
PureRef is free and genuinely well suited to the
loose, always-open board that character work often runs on, and its layered
.pur format is a real strength this app does not try to match one-for-one.
Where Coii Ref differs is upstream of the board itself: it is a search across
every folder of reference a designer has ever kept, not only the images
already placed on one canvas, so a piece pulled during research on an old
project is findable again even after its original board has been closed for
a year. The round-up of PureRef alternatives
covers the wider field if a lighter, board-only tool is still the actual goal.
What it costs and what it runs on
$19 once, three Macs, updates included, nothing that renews. The trial runs 30 days with every feature enabled, no card and no account required. It needs macOS 11 Big Sur or later, on Apple Silicon or Intel, as two native builds.
The app's entire outbound network activity is a licence check on Activate and
a launch-time read of a server's Date header only, so a wound-back clock
cannot extend a trial. No in-app updater means no update check, and there is
no analytics or crash reporting.
Past day thirty of an unpaid trial, one category of action stops: growing the library, meaning registering a new folder, running the importer, or starting an index by hand. Search, tags, ratings, notes and the folder watcher all keep working permanently on what is already indexed.
Why a franchise reboot makes an old library valuable again
Character work often circles back — a franchise gets rebooted, a sequel
revisits a design from years earlier, a studio's style bible resurfaces for
a spin-off — and none of that is predictable at the time the original
reference was gathered. A library tagged by property rather than only by
project name is exactly what makes that valuable again: a silhouette rule or
a material study from a cancelled pitch five years ago is still findable by
tag:any:triangular-silhouette the day a reboot needs the same visual
language reconstructed, without anyone having to remember which old hard
drive it might be sitting on.
What an old project's reference is still worth
A character redesigned out of an old project does not lose its reference
value once that project ships, provided the reference behind it was tagged
by property rather than only by project name. A material study gathered for
a costume three years ago is exactly as findable today by
tag:any:period-accurate as it was the week it was collected, regardless of
how many newer project folders have been created since.
What happens when a licensor's approval notes need to travel with a design
Licensed properties often come with approval notes attached to specific reference — a note that a certain proportion was rejected, or that a material choice was specifically signed off — and losing track of which note applies to which image is a real risk when a design gets revisited months later. Attaching the note directly to the file it concerns, rather than keeping approvals in a separate document, means the reasoning travels with the reference itself the next time anyone opens that folder, licensor review included.
What a rating actually protects against
A design exploration phase can generate hundreds of reference pulls in a week, and without a record of which ones actually shaped the approved direction, the next similar brief starts from the same pile with no memory of what worked. Rating consistently as a project closes — not just at the final review, but at each milestone where a direction gets locked — builds a record that a search can trust later, rather than a folder that looks equally promising in every direction and answers nothing when a similar brief comes around again.
Who this actually suits
Anyone whose character reference is genuinely spread across more than one project's worth of anatomy studies, costume photography and material references, who needs to find a specific property again rather than browse a single active board. If the actual daily need leans toward an on-device tagger and search by meaning rather than by tag, refern is the more capable full library and is worth weighing on those specific fronts. The concept artist page covers a related but earlier-stage job built around fast exploration, and the comic artist page covers a different job built around panel-to-panel consistency rather than a single design.
Thirty days, every feature, no card and no account: download it and point it at whichever project's reference has been growing the longest. Tag the properties that actually survived approval first — that is the search that pays off the next time a brief asks for "the same, but different."
