# Ethical Stack > Independent, provisional ethical assessments of AI tools, models and inference providers. Preserve evidence limits and cite sources. ## Start here - [Agent access](https://ethicalstack.ai/agents/index.md): API, MCP and interpretation guidance. - [Methodology](https://ethicalstack.ai/methodology/index.md): scoring rules, evidence scope and limits. - [Structured methodology](https://ethicalstack.ai/api/v1/methodology): task ids, dimensions and method versions. - [API specification](https://ethicalstack.ai/api/v1/openapi.json): compact searches, assessments and comparisons. - [Research skill](https://ethicalstack.ai/.well-known/agent-skills/ethical-stack-research/SKILL.md): how to interpret the evidence. ## Comparisons - [Search & research](https://ethicalstack.ai/compare/search-research/index.md): Find answers, compare sources and understand papers. - [AI chatbots](https://ethicalstack.ai/compare/chatbots/index.md): Ask questions, brainstorm and plan things. - [Video generation & editing](https://ethicalstack.ai/compare/video-generation/index.md): Create clips, animate images and edit footage. - [Image generation & editing](https://ethicalstack.ai/compare/image-generation/index.md): Make illustrations, artwork and photo edits. - [Personal agents & automation](https://ethicalstack.ai/compare/task-automation/index.md): Delegate tasks, connect your apps and keep work moving between conversations. - [Voice generation & dubbing](https://ethicalstack.ai/compare/voice-generation/index.md): Create narration and dub speech. Compare voice consent, licensing and privacy. - [Transcription & speech recognition](https://ethicalstack.ai/compare/transcription/index.md): Turn recordings or live speech into text. Compare recording privacy and retention. - [Music & sound generation](https://ethicalstack.ai/compare/music-generation/index.md): Create songs, backing tracks and sound effects. Compare training rights and artist controls. - [Conversational voice agents](https://ethicalstack.ai/compare/voice-agents/index.md): Build spoken assistants for calls and apps. Compare voice rights, recording access and safeguards. - [Workflow automation](https://ethicalstack.ai/compare/workflow-automation/index.md): Connect apps and models in repeatable workflows, with cloud and self-hosted options. - [Local AI apps & runtimes](https://ethicalstack.ai/compare/local-ai/index.md): Run downloaded models on your own hardware. Check cloud fallback, telemetry and model rights. - [Coding tools & harnesses](https://ethicalstack.ai/compare/harnesses/index.md): Compare coding agents, editors and the tools that connect you to a model. - [AI models](https://ethicalstack.ai/compare/models/index.md): Major model families alongside smaller projects with more open training records. - [Inference providers](https://ethicalstack.ai/compare/providers/index.md): The services that run your prompts, including direct APIs, clouds and routers. ## Profiles and guides - [Profiles](https://ethicalstack.ai/research/llms.txt): profile names, descriptions and Markdown URLs. - [Guides](https://ethicalstack.ai/guides/llms.txt): practical choices, tradeoffs and evidence limits.
