Andi

Andi processes web search results through a generative AI model (likely GPT-4 or similar) to synthesize direct answers rather than returning ranked link lists. The system retrieves relevant documents, extracts key information, and generates coherent natural language responses that directly address user queries, eliminating the need for users to visit multiple sources. This differs from traditional search engines that rank documents by relevance; Andi performs semantic understanding and abstractive summarization in real-time.

After generating an initial answer, Andi's system analyzes the query and response to suggest 3-5 contextually relevant follow-up questions that users can click to refine their search. This is implemented as a post-processing step that uses the generated answer and original query as context for a secondary generative model call to produce natural refinement paths. The suggestions appear as clickable chips below the answer, enabling multi-turn search without requiring users to retype or manually construct new queries.

Andi maintains a web crawler and indexing pipeline that retrieves current documents matching user queries in real-time, then ranks them by relevance to feed into the generative synthesis step. The system likely uses a combination of full-text search (BM25 or similar) and semantic ranking (embedding-based similarity) to identify the most relevant sources before passing them to the LLM. This retrieval layer is critical because the quality of synthesized answers depends entirely on the quality and recency of retrieved sources.

Andi operates as a completely free, unauthenticated service with no paywall, premium tier, or login requirement. Users can access the search engine directly via web browser without creating an account, providing API keys, or paying subscription fees. This is a business model and UX choice that prioritizes accessibility over monetization, contrasting with ChatGPT+ (paid) and Google (ad-supported).

Andi's generated answers include minimal or inconsistent source attribution. While some answers may include hyperlinks to source documents, the system does not provide explicit citations (e.g., '[1]', '[2]') or a structured bibliography showing which sources contributed to which parts of the answer. This is a significant architectural limitation because it makes it difficult for users to verify claims, trace information origins, or understand the confidence level of synthesized statements. The system prioritizes answer readability over citation transparency.

Andi generates answers to individual queries without maintaining conversation history or persistent user context across sessions. Each search is treated as an independent request—the system does not retain previous queries, answers, or user preferences to inform subsequent searches. This is a stateless architecture that simplifies backend infrastructure but limits the ability to provide personalized or context-aware refinements. Follow-up suggestions are generated based only on the current query and answer, not on the user's search history.

Andi is accessible exclusively through a web browser interface (andisearch.com) with no public API, SDK, or programmatic access. Users interact with the search engine through a web UI that accepts text queries and displays synthesized answers. There is no way for developers to integrate Andi's capabilities into third-party applications, build custom search experiences, or automate queries programmatically. This is a distribution choice that limits extensibility but simplifies product management.
