Description
Biel.ai turns technical documentation into an AI assistant that gives developers instant, accurate, source-cited answers. It is built for products where documentation drives adoption and a wrong answer costs real engineering time.
Biel understands the structure of developer content: OpenAPI specs, code samples, error codes, and configuration files are parsed as what they are, not as flat text. When a user asks "why am I getting a 401", the assistant connects the question to the relevant endpoint and returns a direct answer with sources, instead of a list of links. Every response is drawn exclusively from your indexed content, so there are no invented answers about your product.
One knowledge base powers four surfaces. A widget brings Ask AI chat and AI search to docs built with Docusaurus, Sphinx, MkDocs, Antora, Starlight, Next.js, WordPress, or plain HTML, live in about 15 minutes. A hosted MCP server lets developers query your docs from Claude, Cursor, GitHub Copilot, and other MCP-compatible tools. Bots for Slack, Discord, and Microsoft Teams answer questions directly in team channels. A REST API and RAG-as-a-Service option embed the same capability into your own product.
Biel also works as a content intelligence layer. Analytics reveal the questions users asked, the ones that went unanswered, and the pages that need improvement, so documentation teams can close gaps before they turn into support tickets. It supports multiple languages, syncs content automatically via crawls, GitHub, or API, and runs on EU-hosted infrastructure with AES-256 encryption, GDPR compliance, SSO, and bring-your-own-keys support.
Teams at ScyllaDB, Katalon, Tezos, and Talon.one use it in production.
Description
Sphinx is a high-performance open-source full-text search engine specifically designed to prioritize efficiency, search quality, and ease of integration. Built using C++, it operates seamlessly across various platforms including Linux (such as RedHat and Ubuntu), Windows, MacOS, Solaris, FreeBSD, and several others. Sphinx supports both batch indexing and on-the-fly searching of data from SQL databases, NoSQL systems, or even plain files, allowing for a flexible approach similar to querying a traditional database server. The platform offers numerous text processing capabilities that facilitate the customization of its functions to meet the distinct needs of different applications, while multiple relevance tuning options help enhance the quality of search results. Implementing searches through SphinxAPI requires only three lines of code, and using SphinxQL is even more straightforward, enabling users to write search queries in familiar SQL syntax. Remarkably, Sphinx can index between 10 to 15 MB of text in a second for each CPU core, translating to over 60 MB per second on a dedicated indexing server. With its robust features and efficient performance, Sphinx stands out as an excellent choice for developers seeking a search solution tailored to their specific requirements.
