Read this page as one judge. Each weighs the same scores by what they care about.

The Brand Marketer

Weighted verdict

Keeps the brand consistent across twelve sales offices that make their own flyers. Wants locked templates non-designers can use, guidelines inside the tool, licence and expiry dates on every stock image, and a clear answer on whether a generated image may go on a trade-fair stand.

Same scores as the panel view — this lens weights them the way this judge cares.

Design, prototyping & design systems

How this is scored

The making itself: vector and layout tools, interactive prototypes, and the shared components, styles and tokens that keep a company's products and materials consistent — judged on what the feature and help pages document, not on showcase images.

0 — Not a design tool: a file viewer, a stock library or a single-purpose converter in which nothing is laid out or drawn.

3 — A canvas or editor with templates, shapes, text and images; reusable components, shared styles and prototyping are basic or not described.

5 — Reusable components or styles shared across files, responsive or auto layout, and clickable prototypes or presentations linking screens.

8 — A design system managed in the tool: team libraries that update where they are used, variables or tokens for colour, type and spacing with modes or themes, component variants and properties, prototypes with transitions and conditional logic, and library changes published with versions.

10 — The design system is a governed product: library releases versioned and reviewable, token export in a documented format for development, usage analytics per component, and accessibility checks such as contrast built into the editor.

Report an error

The Brand Marketer

Reusable components whose instances update from the main component, auto layout on containers and objects, and prototypes driven by logic, variables and formulas are all well documented, and Figma import even carries variants. But we found no public information on team libraries shared across files or colour, type and spacing tokens with themes and versioned publishing, which is what would keep a dozen offices producing the same look. 1 2 3 6

Report an error

Collaboration, review & developer handoff

How this is scored

Working on the same files with colleagues, clients and developers: comments and review, permissions for internal and external people, and the handoff that gives engineering measurements, assets and code rather than screenshots.

0 — A single-user tool: files are worked on alone and passed on as exports.

3 — Files shared by link with comments or real-time co-editing; guest access, permissions and a developer view are basic or not described.

5 — Real-time co-editing, comments with mentions, sharing with view or edit rights per file or project, and an inspect or developer view with measurements and asset export.

8 — Guests and reviewers who comment without a paid seat, version history with restore, branching or review of changes before they reach the main file, a developer mode that links components to code, a documented API and plugins, and named integrations with issue trackers and code tools.

10 — Handoff is a contract between design and code: component properties mapped to code components, token and asset export automated through the API, an audit log of access and sharing, and external access governed by domain, expiry and admin policy.

Report an error

The Brand Marketer

Sharing is covered properly — view and download controls, password protection, team-space restriction and link expiry on the Enterprise plan — and engineers get interaction recordings with interaction specifications rather than screenshots. We found no public information on comments with mentions, real-time co-editing, guest reviewers without a paid seat, or an inspect view with measurements and asset export. 1 4 5 7

Brand assets & governance

How this is scored

Keeping a brand usable and correct across a company: a central library for logos, images and templates, brand guidelines people can find, locked templates that let non-designers produce material, and rights and expiry metadata on every licensed asset.

0 — No shared assets of any kind; the product has no library, kit or template that a team uses together.

3 — A shared folder, brand kit or template set with logos, colours and fonts; locking, guidelines and asset metadata are basic or not described.

5 — A central brand kit or library with logos, colours and fonts, team templates that non-designers can fill, and the ability to lock brand elements or restrict who edits templates.

8 — Brand guidelines published in the tool, tagging and search across assets, approval workflows for new assets and template output, version control on assets, rights, usage and expiry metadata with warnings on expiry, and access per team, market or partner.

10 — Brand governance is auditable: every asset carries its licence, owner and permitted use, usage of each asset is tracked across files and channels, distribution to external partners is logged, and the whole library with metadata is exportable in a documented format.

Report an error

The Brand Marketer

The captured pages present an advanced prototyping tool: they describe a local component library and prototypes shared with team spaces, and we found no public information on a brand kit, locked templates non-designers can fill, guidelines inside the tool, or licence and expiry metadata on any asset. Nothing here answers my flyer problem across twelve offices. 1 5 6

Files, formats & portability

How this is scored

Whether the work can leave: open or documented file formats, export that keeps layers, vectors and components, offline or self-hosted options, and what happens to files after a downgrade, a removed seat or a cancelled contract.

0 — Work cannot leave the product: no export or download of designs is offered.

3 — Export of designs as images or PDF per page or frame; export of whole files with structure and access after cancellation are basic or not described.

5 — Export to PNG, PDF and SVG with vectors and text kept, whole files downloadable to a local copy, and files of a downgraded or cancelled account addressed in the help centre or terms.

8 — An open or publicly documented file format, import from and export to other named tools documented, bulk export of a team’s files, an API that reads full file structure, files of removed users transferred to the organisation by policy, and a stated retention and deletion timeline after the contract ends.

10 — Portability is built in: an open-source or openly specified format, self-hosting or a local-first option, round-trip export without loss of components and prototypes, and the customer’s ownership of all files and their export rights written into the terms.

Report an error

The Brand Marketer

Figma import is documented in real depth — components, variants, auto layout and constraints carried over, with ProtoPie edits preserved on reimport — and prototypes can be restricted for download or exported as scene, object or flattened. We found no public information on an open or documented file format, bulk export of a team's work, or what happens to files after a downgrade or cancelled contract. 5 6 7 8

AI features & rights to the work

How this is scored

What the vendor's AI does with the customer's files and what the customer may do with the AI's output: training on customer content and the opt-out, the models and where they run, commercial use of generated images, stock licences and indemnity.

0 — The terms state that customer files train the vendor’s models with no opt-out, or that generated output may not be used commercially.

3 — AI features described on an AI or help page with a general statement on responsible use or data handling; training on customer files, admin controls and output rights are basic or not described.

5 — A statement on whether customer content trains the models (excluded, or with a documented opt-out), AI features that an admin can switch off for the organisation, and commercial use of generated output addressed in the terms or AI page.

8 — Training excluded by default for business plans, model providers and the processing location of AI features stated, generated content labelled or carrying content credentials, stock and template licences stated per asset type, and an IP indemnity for generated output on a named plan.

10 — AI is governed in writing: a per-feature list of models, providers and locations, admin controls per team and feature, a log of AI use, training exclusion and output ownership in the contract terms, and indemnity and licence limits published in full.

Report an error

The Brand Marketer

The AI terms answer my trade-fair question directly — users retain all rights in their inputs and own the outputs — and name the providers with locations (Anthropic and OpenAI in the United States, Microsoft and Alibaba for mainland China residents), retention periods and an organization-level on/off switch for Enterprise administrators. It stops short of comfort because inputs from Basic and Pro users may be used to improve the services with no opt-out described for those plans, we found no public information on content credentials or any IP indemnity, and everything is provided as-is with no warranties. 1 8

European sovereignty

How this is scored

Who the contracting entity is, where design files, brand assets and AI prompts are stored and processed, and which subprocessors touch them. Independently sourced by the sovereignty pipeline.

0 — Proven non-EU on every dimension the evidence covers: non-EU contracting entity and non-EU hosting, with no EU option stated.

3 — One European element proven: an EU contracting entity or EU representative, EU data residency (even if only on an enterprise plan), or a published DPA, with the rest of the chain unstated.

5 — EU hosting stated for files as standard or selectable and an EU contracting entity or EU representative, with a DPA offered; the subprocessor chain (AI, rendering, support) is unstated or partly non-EU.

8 — EU contracting entity, files, assets and backups stored in the EU on named infrastructure, subprocessor list published with locations and purposes, and the processing location of AI features stated.

10 — Sovereign end to end and evidenced: European ownership, EU entity, every hosting, AI and support subprocessor European or optional, self-hosting or a European cloud offered, and certifications published.

Report an error

The Brand Marketer

The proven dimensions are all non-European: all AI data is processed through Anthropic PBC in the United States, data-residency selections are listed among unsupported options, and every named AI provider sits in the US or China. The contracting entity's jurisdiction and where our stored prototypes are hosted remain unknown, and no European element appears in the evidence. 1 8

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a buyer can compute the annual cost for their team from public pages alone — which seat types exist and what each may do, how viewers and guests are billed, how seats are added and trued up, AI credits, and the plan where SSO, admin controls and brand features begin.

0 — No public prices at all; every plan is a sales conversation.

3 — A public "from" price or one priced plan, per seat or flat.

5 — Per-seat prices public for the main plans with the billing period stated and the main features per plan listed.

8 — Every plan and seat type priced, free viewers and guests stated with their limits, how and when added seats are billed explained, AI credits and storage priced or included explicitly, the plan that unlocks SSO and admin controls named, and VAT treatment stated.

10 — Complete cost computability: annual cost derivable for a given mix of editors, viewers and guests, true-up and auto-upgrade rules published, every add-on priced publicly, and contract term, renewal and downgrade conditions stated.

Report an error

The Brand Marketer

A free plan is public — "Start prototyping today 100% free" with interaction recordings and shareable links — and the plan family plus AI credit pooling and monthly reset rules are visible across the pages. But we found no public information on paid seat prices, billing periods or VAT treatment, so I cannot compute a year's cost for my team from what was captured. 1 4 5 8
