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

The Skeptic

Weighted verdict

Has read "European AI" on a wrapper that sends every prompt to a US model, "agents" that are saved prompts, and "we never train on your data" with no word on the model provider behind it. Asks which model answers, where it runs, what it may do unsupervised, and what a thousand seats cost.

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

Data use, training & retention

How this is scored

What happens to prompts, uploaded files, connected data and outputs: whether any of it trains a model (the vendor's or a model provider's), how long it is kept and where logs live, whether zero-retention is available, and whether a data processing agreement covers it.

0 — No statement on training or retention; the privacy policy is a website policy that does not cover the product.

3 — A general statement that business data is "not used for training", with no word on retention, on the model providers behind the product or on logs.

5 — Business data excluded from training by contract, retention periods stated for chats and files, and a DPA offered to business customers.

8 — No-training commitments stated for the vendor and every model provider it routes to, retention configurable by the admin (including deletion of chat history), zero-data-retention terms with the model providers named, and abuse-monitoring retention described.

10 — Data use fully accounted for: training, retention, logging and abuse monitoring stated per model provider, customer-controlled retention and deletion with an audit trail, outputs and connected data treated as customer data in the DPA, and an independent audit (SOC 2, ISO 27001 or ISO 42001) covering the product.

Report an error

The Skeptic

The privacy policy commits in writing that prompts and completions are not used to train or improve LightOn's models except on the customer's explicit written request, retention periods are stated per data type (chats two months, access logs up to ninety days for abuse detection, usage metrics thirteen months after contract end), and a DPA is available with LightOn acting as an Article 28 processor. Audit-log retention is admin-configurable and abuse-monitoring retention is described, which is more than most bother to publish. But chat history and ML logs sit outside that retention control, the anonymization job replaces values while "no data is deleted", and no independent audit statement appears. 1 2

Models & processing location

How this is scored

Which models sit behind the product and who runs them, where inference and storage happen, whether the customer can pin processing to the EU, choose or exclude model providers, bring its own model or key, or run the product in its own cloud or on premises.

0 — The models behind the product and the processing location are not stated.

3 — The model family is named, but where inference runs and through which provider (the model maker, a hyperscaler, the vendor) is unstated.

5 — Models and their providers named, with an EU processing option stated for storage and at least the default model.

8 — Each available model listed with provider and inference region, EU-only processing selectable by the admin and enforced across models, model providers excludable, and bring-your-own-key or own-cloud deployment documented.

10 — Processing fully under the customer's control and documented: EU-only or on-premises inference for every feature including agents and connectors, open-weight or self-hosted models supported, data flows per feature published, and a residency commitment in the contract rather than on a marketing page.

Report an error

The Skeptic

Inference runs on nodes under LightOn's own control in service-provider data centers "in France or in Europe", with a self-hosted deployment option and stateless inference stated — so the model maker, operator and region are at least answered in principle. However, only model categories are published (language, embedding, vision, multi-vector), no individual model is named, the hosting providers behind that statement are unnamed, and "primarily" reads as intent rather than an admin-enforceable EU pin. 1 3

Admin, identity & access controls

How this is scored

What the IT department controls: SSO and SCIM provisioning, roles and groups, which models, agents and connectors each group may use, retrieval that respects the permissions of the source system, audit logs, usage reporting, and policies such as data-loss prevention — and whether reporting on staff use is scoped and documented.

0 — No admin features documented; accounts are individual sign-ups.

3 — A team workspace with an owner and member invitations, but no SSO, no roles and no audit log.

5 — SSO, admin and member roles, user management, and an admin view of usage.

8 — SAML/OIDC SSO with SCIM provisioning, group-based permissions for models, agents and connectors, retrieval that inherits source-system permissions, exportable audit logs, and usage analytics with documented scope.

10 — Governance a regulated company can operate: fine-grained policies (DLP, content filters, prompt and output logging rules), audit logs streamed to a SIEM, per-agent ownership and approval, usage reporting that can be aggregated or pseudonymised for works-council agreements, and every admin action logged.

Report an error

The Skeptic

SAML and OIDC single sign-on per company, SCIM 2.0 provisioning tested with Microsoft Entra ID, and LDAP are documented, alongside real role separation (Company Admin, System Admin, group Owner), group-based control over which agents and workspaces each team may reach, and per-datasource access control. Audit logs exist with configurable retention and anonymization. We found no public information on exportable audit logs, data-loss prevention policies, or any usage reporting on staff use. 2 4 5 6 7

Integrations, connectors & knowledge

How this is scored

How the product reaches company knowledge and systems: connectors to file stores, wikis, mail, CRM, ticketing and ERP, how fast and how completely they sync, the API, support for open protocols such as MCP, and how the assistant cites the sources it answers from.

0 — No integrations; users paste text or upload files one at a time.

3 — File upload and one or two connectors (for example a drive), with no API and no statement on sync or citations.

5 — A connector library covering the common file stores, wikis and collaboration tools, answers citing sources, and a documented API.

8 — Connectors to file stores, wikis, mail, CRM and ticketing with incremental sync, custom connectors or MCP support, an API and webhooks for embedding assistants and agents in other tools, and source citations on every grounded answer.

10 — The product sits in the company's systems: read and write connectors with documented scopes, MCP servers and clients, contact-centre or telephony integration where relevant, a knowledge layer that can be audited and corrected, and the data, agents and configuration exportable when the customer leaves.

Report an error

The Skeptic

What is published is concrete but narrow: Google Drive and ServiceNow datasources sync automatically into unified search, the v3 API is documented down to agents, tools and MCP servers, and agents can attach MCP servers. We found no public information on connectors to wikis, mail, CRM or ERP, on sync frequency or completeness, or on whether answers cite the sources they were drawn from. 3 6 7

Agent capabilities & guardrails

How this is scored

What an agent can actually do and where it stops: multi-step tasks, tool use and actions in other systems, scheduling and triggers, human approval before consequential actions, run logs, evaluation and testing before release, and the limits the vendor states rather than hides.

0 — No agents; the product is a chat window, whatever the marketing says.

3 — Saved prompts or custom assistants with instructions and files, but no actions in other systems and no run history.

5 — Agents that call tools or APIs and run multi-step tasks, built without code, with a log of each run.

8 — Agents that act in connected systems with scoped permissions, human approval configurable per action, triggers and schedules, test and evaluation tooling before release, and documented limits and failure handling.

10 — Agents a business can put in production and account for: versioning and staged rollout, evaluation against test sets, monitoring of quality and cost per agent, handover to a human with full context, every action attributable to the agent and the person who deployed it, and the vendor's own statement of what agents must not be trusted with.

Report an error

The Skeptic

These are not saved prompts: an agent combines instructions, a model, native tools and MCP servers, scoped workspaces and team access, and can autonomously chain one to five consecutive tools, with stated limits such as no switching mid-conversation and admin-only creation of company-wide agents. We found no public information on run logs for each execution, human approval before consequential actions, triggers or schedules, or evaluation before release — so nothing on these pages shows where an agent's actions are recorded or where they can be stopped. 7 8

European sovereignty

How this is scored

Who the contracting entity and the parent company are, where customer data is hosted, and who the subprocessors are — model providers above all, then hosting, search, telephony and email. Independently sourced by the sovereignty pipeline; for an AI product the model provider is a subprocessor, so a European interface over a non-European model counts as such.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors (including model providers) unnamed.

3 — A privacy policy exists, but hosting location is unstated or non-EU and the model providers behind the product are not named as subprocessors.

5 — EU hosting stated and an EU contracting entity, but prompts reach non-EU model providers or other subprocessors without a stated safeguard or EU region.

8 — EU hosting on named infrastructure, EU contracting entity, every subprocessor listed with its location including model providers, EU inference available, and a DPA offered.

10 — Sovereign end to end and evidenced: European ownership, entity, hosting and model processing, every subprocessor European or optional, data export and deletion documented, and a security or certification statement published rather than implied.

Report an error

The Skeptic

The contracting entity is LightOn SA at 2 rue de la Bourse, Paris (SIREN 821 100 690), processing is stated to run in service-provider data centers "in France or in Europe" with inference on LightOn's own nodes, and a DPA is offered — a European provider running its own models, not a wrapper. The one disclosed non-European subprocessor, Sentry Inc., touches only masked error telemetry under SCCs with a relay filtering personal data before transmission. But the hosting providers themselves are unnamed and the full processor list is only available on request, so the chain cannot be verified end to end from public pages. 1

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a company can compute the real annual cost from public pages alone: price per seat, per agent, per conversation or per usage unit, what is included in each tier, usage limits and overage, which models, connectors or agents cost extra, minimum seats and term.

0 — No public prices at all; every customer is a sales call.

3 — A starting price or "from" figure exists, but usage limits, included models and what scales the cost are unclear.

5 — Prices per tier are public with the main inclusions, but usage limits, overage, agent runs or enterprise features (SSO, audit logs, EU processing) are unpriced or "on request".

8 — Every tier priced publicly with seat or usage units, usage limits and overage rates, add-ons listed, minimum seats and term stated.

10 — Complete price computability: annual cost derivable for a given number of seats, agents or conversations, with every usage rate, model surcharge, add-on and support tier and the cancellation and data-return terms published.

Report an error

The Skeptic not rated — no public information

We found no public information on pricing in the captured pages: no per-seat or per-usage price, tier, limit, minimum term or surcharge appears anywhere. The privacy policy confirms card data goes to a payment provider, but states no figure a buyer could use. 1
