You can chat with a range of popular AI models from a clean web interface, with no account required, and the company's stated goal is to keep your prompts from being linked to your identity or used to build an advertising profile. The service is deliberately positioned as a low-friction entry point to AI: no app to install, no subscription, and no personal details to hand over before you can ask a question. For people who are uneasy about their chat history sitting inside a mainstream AI account, Duck.ai offers a simpler alternative that behaves more like a private search box than a social profile. It sits alongside DuckDuckGo's broader privacy toolkit, which includes tracker blocking, cookie prompts management, email protection, and browsing protections, so users already invested in that ecosystem can add AI chat without introducing a new set of trackers. **Pricing & Plans:** Free to use, with no account required. No paid tier is advertised for the chat service itself. - **Multiple AI models:** Choose among several leading AI assistants from a single interface instead of juggling separate apps. - **No account needed:** Start chatting without signing up, handing over an email, or creating a profile. - **Privacy-first handling:** Chats are designed to stay detached from your identity rather than being tied to an ad profile. - **Integrated in DuckDuckGo:** Accessible alongside the search engine and browser that already block trackers and cookie pop-ups. - **Browser-based:** Works in the browser on desktop and mobile with no install step. **Strengths:** Free with no signup required; Backed by DuckDuckGo's established privacy reputation; Several leading models in one place; Fits naturally with existing DuckDuckGo tracker blocking **Limitations:** Fewer power-user features than dedicated AI apps; Conversation history and memory features are intentionally limited; Model selection and availability can change over time [Profile (Markdown)](https://openaitools.app/tool/duck-ai.md) ## MarsCode (Trae AI IDE) MarsCode is a development toolkit built around an AI programming assistant. Inside the editor it suggests single lines or whole functions as you type, turns plain-language comments into working code, explains unfamiliar project files, spots bugs and proposes fixes, and answers targeted programming questions. The assistant understands natural language, so you can describe the behaviour you want and get usable code recommendations instead of hunting through documentation. Beyond the assistant, MarsCode ships a configuration-free cloud IDE that runs in the browser. You can create a project from a template or import a Git repository, start coding immediately in a ready-made environment, and use one-click elastic deployment that also produces an access API. A companion plugin system built on Schema helps teams develop, test, deploy and distribute AI agents, including code-to-GPTs workflows that handle schema and OpenAPI management for you. The service is aimed at individual developers and small teams who want to move faster without setting up local tooling. It supports a wide range of languages and mainstream IDEs through its extensions, and the core experience is free to start. Note that the MarsCode name has been folded into the broader Trae AI IDE branding, so you may land on Trae pages when you visit the site. **Pricing & Plans:** MarsCode is offered free to start, with no credit card required to use the AI assistant and cloud IDE. The homepage presents a 'Start for Free' entry point; paid tiers for the wider Trae product family may be offered separately, so check the current site for the latest plan details. - **AI code completion and generation:** Get single-line or full-function suggestions while typing, and turn natural-language comments into working code snippets. - **Code explanation and AI Q&A:** Ask questions about a codebase and receive precise explanations that speed up onboarding onto unfamiliar projects. - **Bug detection and fix suggestions:** The assistant identifies problems in your code and recommends smart optimisations rather than only flagging errors. - **Browser-based cloud IDE:** Spin up a configured development environment in the browser from a template or Git import, with no local installation. - **One-click deployment and AI plugins:** Deploy with automatic access APIs and build, test and distribute AI agents using a Schema-based plugin toolchain. **Strengths:** Free to start with both an AI assistant and a full cloud IDE in one product; Works across many languages and plugs into mainstream IDEs; Browser workspace removes environment setup friction; One-click deployment produces a ready access API **Limitations:** The MarsCode brand has been merged into Trae, so naming and product pages can be confusing; Browser-based development may not suit teams with strict local-tooling or compliance requirements; Feature set differs between the web IDE and IDE extensions, so workflows vary by entry point [Profile (Markdown)](https://openaitools.app/tool/marscode.md) ## Frequently Asked Questions ### How do Duck.ai and MarsCode (Trae AI IDE) compare in monthly traffic?
