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

The Localisation Lead

Weighted verdict

Ships every piece in German, English and French for the DACH region and beyond. Wants locales on the field, not copies of the entry, translation status per language, and a documented export of content, model and locales — because a repository that cannot leave is a hostage, not an asset.

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

Planning, editorial calendar & briefs

How this is scored

Turning a content strategy into scheduled work: topics and campaigns, an editorial calendar across channels, briefs that carry the goal, audience and keywords to the writer, and a view of what is due, late or missing.

0 — No planning features; content is created as standalone entries with no calendar, status or owner.

3 — A shared calendar with publish dates and simple statuses, but no briefs, no campaigns or topics to group work under, and no notion of who owns a piece.

5 — An editorial calendar across channels with owners, due dates and custom statuses, briefs attached to each piece, and content grouped by campaign or topic cluster.

8 — Strategy is connected to the plan: topics or personas defined once and assigned to pieces, configurable workflows per content type, workload and deadline views per person, and recurring formats scheduled as series.

10 — The plan is accountable: every published piece traces back to its brief, topic and campaign, gaps in coverage per topic or funnel stage are reported, and plan-versus-published is visible over time without a spreadsheet.

Report an error

The Localisation Lead

Workflows can name stages like Draft, Review and Publish and a Tasks page shows pending actions with assigned users, which is the only planning-adjacent evidence I found. We found no public information on an editorial calendar, briefs, campaigns or due dates, so my German and French editors would still run the plan in a spreadsheet. 5

Report an error

Creation, review & approval

How this is scored

Writing and reviewing content together: editing with comments and suggestions, roles and permissions for internal and external contributors, and an approval trail that records who released which version.

0 — Single-user editing with no comments, no roles beyond admin, and no record of changes.

3 — Comments and a version history exist, but every user can publish, external writers need a full seat, and approval is a status anyone can set.

5 — Roles that separate writing from publishing, inline comments and suggested edits, a version history with restore, and guest or freelancer access limited to assigned pieces.

8 — Configurable multi-step approval per content type or market, mandatory reviewers (legal, product, brand), scheduled publishing that waits for approval, and an audit log of every edit, approval and publish with user and timestamp.

10 — Approval is evidence: the exact version each approver released is preserved and exportable, permissions reach down to field and locale level, and the audit trail is retained for a stated period and available after the contract ends.

Report an error

The Localisation Lead

Approval is engineered seriously: multiple workflows per content type, approval rules restricting who may publish, a two-distinct-reviewer rule, and an audit log recording who moved an entry and when, with custom roles reaching entry and field level. We found no public information on inline comments, suggested edits, freelancer access or scheduled publishing that waits for approval, and the only stated post-termination treatment is deletion of content within 180 days rather than a retained, exportable approval record. 5 6 3

Report an error

Structured content, localisation & export

How this is scored

Whether content is stored as reusable structure rather than pages: a content model, components shared across channels, German and other locales managed side by side, and the whole repository exportable in a documented format.

0 — Content stored as formatted pages with no structure, one language per entry, and no export beyond copy and paste.

3 — Custom fields or templates exist, but localisation means duplicating entries, assets live elsewhere, and the only export is HTML or a CSV of titles.

5 — A configurable content model with reusable components, field-level localisation with fallback languages, a media library with alt text, and an export of entries and assets in JSON or a similar documented format.

8 — References between entries, variants per market or audience, translation workflows with status per locale and connectors to translation services named, and a full export of content, model, locales and assets documented and self-service.

10 — The repository is portable by design: model and content exportable together and re-importable, migration tooling or a CLI documented in both directions, version history included in the export, and no feature that only works while the content stays.

Report an error

The Localisation Lead

Global fields, group fields, JSON rich text and entry references give genuinely reusable structure, and locales sit on entries with a fallback locale and multi-locale queries rather than duplicated copies — the part I care about most. The documented export, however, covers only the content type schema: we found no public information on exporting entries, assets or locale data, on translation status per locale, or on connectors to translation services, and entry variants are offered only as an early access program. 10 7 8

Publishing, distribution & integrations

How this is scored

Getting approved content to where it is read: publishing to websites and channels, a documented API and webhooks, and named connections to the CMS, CRM, analytics, SEO and translation tools a marketing stack already runs.

0 — Content leaves only by copy and paste; no API, no webhooks and no named integrations.

3 — Publishing to one CMS through a plugin, a handful of named integrations, and an API that is mentioned but not publicly documented.

5 — Publishing to websites and several channels from one place, a publicly documented REST or GraphQL API, webhooks on publish and change, and integrations named for at least the common CMS, CRM and analytics tools.

8 — A versioned API with published rate limits and SDKs, preview environments, a marketplace or integration directory with maintained connectors, performance data per piece pulled back from analytics, and a public status page.

10 — The platform is a dependable source for every channel: API deprecation policy published, CDN and delivery SLA stated, scheduled and event-driven publishing documented end to end, and content performance attributed per channel without a separate tool.

Report an error

The Localisation Lead

The GraphQL delivery API is publicly documented in real depth — a default rate limit of 80 requests per second per organization with rate limit headers and HTTP 429 semantics, seven regional endpoints across AWS, Azure and GCP, dedicated infrastructure, live preview, and a Launch module to host projects. We found no public information on webhooks, SDKs, a connector directory naming CMS, CRM, analytics or translation tools, or a public status page. 9 2

AI assistance & content rights

How this is scored

What the platform's AI does with the customer's content and what the customer may do with the AI's: the models and where they run, whether content trains them, opt-out, labelling of generated text, and who holds the rights to output.

0 — AI writing features with no statement on which model is used, where content is sent, or whether it is used for training.

3 — An AI page that names a provider but leaves open whether customer content trains models, where prompts are processed, or whether the features can be switched off.

5 — The model providers named as subprocessors, customer content excluded from training stated in the terms, AI features switchable per workspace by an admin, and ownership of generated output assigned to the customer.

8 — EU processing for AI features stated or selectable, retention of prompts and outputs given in days, generated or AI-edited content markable for EU AI Act transparency, and brand voice or terminology rules applied without uploading content to train a shared model.

10 — AI is governed and documented: per-feature list of model, provider and processing location, admin controls per role and content type, an audit trail of AI-generated changes, and the output rights and any indemnity written into the contract terms.

Report an error

The Localisation Lead

Global AI Settings let an admin switch each AI product off, credits are consumed only while enabled, a Managed LLM is the stated default with LLM choice advertised, and first use requires accepting separate AI terms. Beyond that governance scaffolding we found no public information on whether customer content trains models, where prompts are processed or retained, or who holds rights to generated output; the EU AI Act reference concerns third-party answers that the Canoe product monitors, not labelling of the platform's own output. 12 11 1

European sovereignty

How this is scored

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

0 — Non-EU contracting entity, no statement on where content is hosted, and subprocessors unnamed.

3 — Content hosted in the EU on request or on a higher plan only, or the subprocessor list is absent, or AI and analytics features send content outside the EU without an explained safeguard.

5 — EU hosting stated for content and assets, a DPA available, but the contracting entity or significant parts of the chain (CDN, AI, support) are non-EU without a stated safeguard.

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

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

Report an error

The Localisation Lead

The privacy policy states an EEA instance storing European customers' data in Ireland and Germany while all other customers' data is stored in the United States, and the same sentence excepts data shared with subprocessors located outside the EEA. The contracting company is American, and we found no public information on a published subprocessor list, a data processing agreement, or where AI prompts are processed. 3 9 2

Pricing transparency

How this is scored

Whether a buyer can compute the annual cost for their team, locales and traffic from public pages alone — seats and contributor roles, locales, content records, API calls and bandwidth, AI credits, and the plan where approval workflows or SSO begin.

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

3 — A starting price per month, but what it includes is vague and the limits that drive the real cost (locales, records, API calls, AI credits) are unstated.

5 — Plans priced per seat with their main limits listed, but at least one commonly incurred cost (extra locales, overage on records or API calls, AI credits, guest contributors) is missing or "on request".

8 — Every plan priced with seats, locales, records, API and bandwidth limits and overage rates stated, AI usage priced or included explicitly, and the plan that unlocks approval workflows, SSO and audit logs named.

10 — Complete cost computability: annual cost derivable for a given team, locale count and traffic, every add-on and overage priced publicly, contract term and renewal conditions stated, and the cost of exporting or leaving the platform zero or published.

Report an error

The Localisation Lead

The tiers name what they include — the free tier lists the headless CMS, Brand Kit and Agent OS with no credit card required, every tier includes Agent OS, and Build advertises pay-as-you-go overages — but we found no public information on price figures or on the limits that drive cost for seats, locales, records, API calls or AI credits. I cannot compute an annual price for a trilingual team from the public pages. 2 2 11
