- Hosted Search Infrastructure: Fully managed indexing, replication, sharding and delivery with high throughput and low latency designed for production-scale web and mobile applications.
- Relevance Tuning & Ranking Controls: Fine-grained ranking rules, custom ranking, attribute weighting and business-metric-aware relevance controls for tailoring results to user intent and KPIs.
- Typo-Tolerance & Prefix Matching: Built-in typo tolerance, prefix search, and advanced matching strategies to improve recall and UX for imperfect queries.
- Recommendations & Personalization: Recommend and personalize search and discovery experiences using behavioral signals and product/content metadata to increase conversion and engagement.
- Developer Tools & Observability: Tools like Algolia Analyzer, dashboards, logs and analytics for monitoring search performance, debugging queries and auditing API key usage.
- Hosted Search API with low-latency query serving
- Semantic Answers product (natural-language QA) integrated with GPT-3
- Default typo-tolerance and prefix search capabilities
- Relevance tuning including custom ranking and boosting (e.g., optionalFacetFilters)
- Official open-source SDKs/clients (JavaScript, Go, Swift, Ruby) licensed MIT
- Developer tooling: Algolia Analyzer browser extension for DevTools to capture and analyze requests and API key ACLs
- Documentation, community forum, FAQ and support channels for integration and troubleshooting
Best for
- E‑commerce Product Search: Power product discovery with fast faceted search, relevance tuning, typo-tolerance and personalized recommendations to increase conversion.
- Customer Support & Knowledge Search: Use Algolia Answers to let support desks and help centers surface relevant passages and natural-language answers from documentation and articles.
- Content Discovery for Publishers: Enable semantic search and contextual recommendations across large article collections to boost engagement and time-on-site.
- Application and Site Search: Integrate Algolia client libraries and InstantSearch widgets into web and mobile apps to provide instant autocomplete and result pages.
- Developer Documentation Search: Index technical docs and code examples with precise ranking and typo-resilient search to help users find relevant instructions quickly.
- Headless/Composable Commerce Integration: Synchronize product, catalog and inventory data to power headless storefronts and PWA experiences with consistent search behavior.
- Website and documentation search with relevance tuning
- E-commerce product search (fast, typo-tolerant discovery)
- Customer support and knowledge-base QA using semantic Answers
- Developer/package search (e.g., npm index integrations)
- Mobile app search (iOS via Swift client) and server-side integrations (Go, Ruby, JS)
Feynman
Companion
Open-source AI research agent that reads papers, ranks literature, drafts research and plans experiments from the terminal or a local workbench.
Key features
- Cited Research Briefs: Asking a research question returns a synthesized brief where each claim is tied to the paper or web source it came from, rather than an unsourced summary.
- PaperRank Scoring: Ranks papers on a topic with transparent evidence for citations, methodology, reproducibility and provenance so reading order is a decision you can inspect.
- Paper Access Resolver: Resolves a single DOI, arXiv ID, OpenAlex ID, PMID, PMCID or title against OpenAlex, arXiv/alphaXiv, DOI and Europe PMC, with optional full-text fetching.
- Local Science Workbench: `feynman serve` opens a standalone app with projects, sessions, chat, notebooks, compute, artifact previews and provenance in one place.
- Claim Auditing and Replication: Compares a paper's stated claims against what its code actually does, and generates replication plans with compute targets and gated experiment steps.
- Local and Hosted Models: Works with hosted providers via OAuth or API key and with local runtimes including LM Studio, Ollama, vLLM and a LiteLLM proxy.
- Skills-Only Install: The research skill library can be installed on its own into Claude, Codex or OpenCode projects without the terminal app or bundled runtime.
- Science Artifacts: Reports, data files, spreadsheets, notebooks, LaTeX, chemistry sketches and genomes are browsable together with versions, lineage and execution logs.
Best for
- Deciding What to Read: Ranking a fresh literature pile on a topic by reproducibility and methodology instead of citation count alone.
- Writing a Literature Review: Producing a review that separates where the field agrees from where questions remain open, with citations attached.
- Verifying a Paper's Claims: Auditing whether the results a paper reports are supported by the code and data it released.
- Planning a Replication: Turning a published finding into a concrete replication plan with a compute target and staged experiment steps.
- Running Deep Research Passes: Launching a multi-agent deep dive on a topic that synthesizes findings and verifies them before reporting.
- Keeping Research Local: Running the whole pipeline against a local model so unpublished work and private data never leave the machine.
- Adding Research Skills to a Coding Agent: Installing the skills bundle into an existing Claude or Codex project to get research workflows without a second app.
