# LongCat Web Assistant

LongCat offers web, desktop, and mobile assistant access; its terms describe AI chat and optional web search over public sources.

Canonical profile: https://ethicalstack.ai/products/longcat-chat/

Scope: LongCat web/app assistant for personal use; LongCat API platform is excluded.

Published overall: 3; 5/6 dimensions rated.

Round the equal-weight mean of available numerical ratings to one decimal; require at least four of six for an overall score. BDS status stays outside the mean; for eligible profiles, a boycott target caps the final score at 2/10 and a pressure target subtracts one point (minimum 1). Not listed and not checked do not adjust the score.

## Energy practices

Finding: 1/10

Assessment: https://ethicalstack.ai/products/longcat-chat/#energy

This grades published energy practices, not the service’s actual footprint.

Reason: 1 + 0 reporting + 0 electricity + 0 controls = 1/10. This grades documented practices and transparency.

Argument: The reviewed materials define the LongCat consumer assistant and its functions but provide no service-specific reporting on electricity, emissions, water, sourcing, or resource-reduction controls. Missing measurements do not establish high consumption.

Type: argument; confidence: low

Scope (dimension): LongCat web/app assistant for personal use; LongCat API platform is excluded.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: No comparable service-level electricity, emissions, water, location mix, or independently reviewed footprint is established in these sources.

## Training data

Finding: Depends on the model

Assessment: https://ethicalstack.ai/products/longcat-chat/#training-rights

The hosted route does not identify one fixed model and corpus.

Reason: Training-data rights depend on the exact model and version selected through this hosted route; no single corpus assessment applies.

Argument: This LongCat consumer assistant can expose multiple models or change its model selection over time. The product page is not a source-specific training-data and permissions record for every model served through the route.

Type: argument; confidence: medium

Scope (profile): LongCat web/app assistant for personal use; LongCat API platform is excluded.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Select the exact model and version, then review its training sources, permissions, creator controls, and any API-specific data terms.

## Your data & privacy

Finding: 4/10

Assessment: https://ethicalstack.ai/products/longcat-chat/#privacy

LongCat publishes a privacy policy and user controls, but the reviewed material does not set a fixed conversation-retention period.

Reason: Published privacy terms and account controls provide some transparency, but prompt-specific reuse and fixed retention protections remain unclear.

Argument: LongCat’s agreement describes its AI assistant and optional web search, while its privacy policy lists information categories, support channels, and account management. The policy gives a retention principle tied to purpose and legal requirements rather than a fixed prompt-retention period, and its agreement states this consumer route is for personal, study, research, and entertainment use.

Type: argument; confidence: medium

Scope (profile): LongCat web/app assistant for personal use; LongCat API platform is excluded.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: The reviewed documents do not establish prompt use for model training, the duration of ordinary conversation storage, or the precise human-review process.

## Openness

Finding: 2/10

Assessment: https://ethicalstack.ai/products/longcat-chat/#openness

This is a hosted product route; its interface documentation does not disclose the hosted model implementation or grant access to its weights.

Reason: A hosted interface is documented, but source code, training artifacts, and route-specific downloadable weights are not established in these sources.

Argument: The reviewed LongCat consumer assistant materials describe a hosted service, without publishing the service implementation or checkpoint weights for this route. Its openness rating concerns access to this product surface, not any separately released model family.

Type: argument; confidence: medium

Scope (profile): LongCat web/app assistant for personal use; LongCat API platform is excluded.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: The exact model checkpoint and any route-specific release artifacts may change; this rating covers the named service route.

## Worker protections

Finding: 1/10

Assessment: https://ethicalstack.ai/products/longcat-chat/#labour

No model-specific worker safeguards are established for Meituan LongCat in the reviewed model sources.

Reason: 1 base + 0 conditions + 0 worker voice/remedy + 0 evidence/follow-through = 1/10; this is a disclosure finding, not proof of abuse.

Argument: The model release pages describe weights and technical properties, not conditions for employees, data annotators, evaluators, moderators, or infrastructure contractors. This is a source-bounded disclosure gap, not evidence of mistreatment. This entry carries the same developer/operator finding to LongCat Web Assistant; it does not establish that this product was deployed under every cited relationship.

Type: argument; confidence: low

Scope (dimension): Meituan: the documented developer/operator record, not proof of deployment of LongCat Web Assistant.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: Worker locations, pay and conditions, supplier coverage, voice mechanisms, labor audits, and remediation outcomes are not established by these model-release sources.

## Military ties

Finding: 7/10

Assessment: https://ethicalstack.ai/products/longcat-chat/#military-contracts

No route-specific military relationship or end-use oversight was established for this LongCat web/app assistant for personal use; LongCat API platform is excluded..

Reason: 7 base + 0 safeguard adjustment = 7/10 (0 of 9 safeguard points; every 3 adds 1). No military relationship was established in the cited sources. This ranks above known defense ties without claiming a verified clean record.

Argument: The reviewed LongCat Web Assistant materials describe user access, features, or account rules but do not establish a military customer, military deployment, or a model-specific restriction on military use. This route finding does not resolve the wider company’s government work.

Type: argument; confidence: low

Scope (profile): LongCat web/app assistant for personal use; LongCat API platform is excluded.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: A separate, current company-level review is needed for defense contracts; downstream deployments and any customer-specific safeguards are not established here.

## BDS targets

Finding: Not listed

Assessment: https://ethicalstack.ai/products/longcat-chat/#israel-palestine

Meituan LongCat is not named in the two official BNC campaign lists checked. This is a limited list check, not BDS approval.

Reason: Campaign category, excluded from numerical scoring.

Argument: The official BNC consumer boycott/pressure guide and No Tech campaign page do not name Meituan LongCat among their current targets. BDS uses selective campaigns, so absence from these lists is neutral and does not establish a clean record or approval. This entry carries the same developer/operator finding to LongCat Web Assistant; it does not establish that this product was deployed under every cited relationship.

Type: argument; confidence: medium

Scope (dimension): Meituan: the documented developer/operator record, not proof of deployment of LongCat Web Assistant.

Research reviewed: not recorded; evidence date: not recorded

Unknowns: This check covers only named targets in the two cited BNC campaigns; it does not cover all BDS campaigns, local groups, investments, suppliers, or downstream hosts. Lists and ownership may change.

## Reading the evidence

- Assessments are provisional editorial judgments. Cite the profile and the underlying sources, and retain confidence, scope and unknowns.

- Unknown, not-applicable and model-dependent are different states. Missing evidence does not establish good or bad conduct.

- Company-level evidence does not establish use of a particular product or model. Account plan, model, host and route can change an assessment.

- Energy scores describe documented practices and transparency, not measured request emissions. Zero component points can mean an evidence gap.

- Published overall scores require at least four of six numerical dimensions. Preserve coverage and BDS adjustments; BDS itself is categorical.

- No named BDS target found is limited to the reviewed campaign sources and is not approval. Personalized priorities do not change the published overall score.

- Review and source-check dates describe the research, not this deployment. Fetch current primary sources when the decision requires current verification.
