Enables users to query organizational knowledge using conversational language rather than keywords or boolean operators. The system interprets intent and returns relevant documentation, processes, and institutional knowledge from the wiki.
Automatically captures and converts unstructured information from Teams conversations, emails, and documents into structured wiki documentation. Reduces manual documentation burden by extracting knowledge from existing communication.
Manages who can view, edit, and publish wiki content based on roles, teams, and permissions. Ensures sensitive information is protected while enabling appropriate access for different user groups.
Provides analytics on wiki usage, content popularity, search patterns, and user engagement. Identifies gaps in documentation and helps optimize knowledge management strategy.
Automatically categorizes and tags wiki content using AI analysis of document content. Eliminates manual tagging overhead and improves content discoverability through consistent taxonomy application.
Provides seamless wiki access directly within Microsoft Teams interface through channels, tabs, and search integration. Eliminates context-switching by keeping knowledge management within the Teams workflow.
Provides pre-built or customizable HR and onboarding documentation templates and processes. Enables rapid creation of standardized onboarding materials, policies, and new-hire information.
Organizes and surfaces customer-facing documentation, FAQs, and troubleshooting guides for support teams. Enables support agents to quickly find answers and provide consistent information to customers.

Stores vector embeddings and metadata in JSON files on disk while maintaining an in-memory index for fast similarity search. Uses a hybrid architecture where the file system serves as the persistent store and RAM holds the active search index, enabling both durability and performance without requiring a separate database server. Supports automatic index persistence and reload cycles.
Unique: Combines file-backed persistence with in-memory indexing, avoiding the complexity of running a separate database service while maintaining reasonable performance for small-to-medium datasets. Uses JSON serialization for human-readable storage and easy debugging.
vs alternatives: Lighter weight than Pinecone or Weaviate for local development, but trades scalability and concurrent access for simplicity and zero infrastructure overhead.
Implements vector similarity search using cosine distance calculation on normalized embeddings, with support for alternative distance metrics. Performs brute-force similarity computation across all indexed vectors, returning results ranked by distance score. Includes configurable thresholds to filter results below a minimum similarity threshold.
Unique: Implements pure cosine similarity without approximation layers, making it deterministic and debuggable but trading performance for correctness. Suitable for datasets where exact results matter more than speed.
vs alternatives: More transparent and easier to debug than approximate methods like HNSW, but significantly slower for large-scale retrieval compared to Pinecone or Milvus.
Accepts vectors of configurable dimensionality and automatically normalizes them for cosine similarity computation. Validates that all vectors have consistent dimensions and rejects mismatched vectors. Supports both pre-normalized and unnormalized input, with automatic L2 normalization applied during insertion.
vectra scores higher at 38/100 vs Perfect Wiki at 34/100. Perfect Wiki leads on quality, while vectra is stronger on adoption and ecosystem. vectra also has a free tier, making it more accessible.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
Unique: Automatically normalizes vectors during insertion, eliminating the need for users to handle normalization manually. Validates dimensionality consistency.
vs alternatives: More user-friendly than requiring manual normalization, but adds latency compared to accepting pre-normalized vectors.
Exports the entire vector database (embeddings, metadata, index) to standard formats (JSON, CSV) for backup, analysis, or migration. Imports vectors from external sources in multiple formats. Supports format conversion between JSON, CSV, and other serialization formats without losing data.
Unique: Supports multiple export/import formats (JSON, CSV) with automatic format detection, enabling interoperability with other tools and databases. No proprietary format lock-in.
vs alternatives: More portable than database-specific export formats, but less efficient than binary dumps. Suitable for small-to-medium datasets.
Implements BM25 (Okapi BM25) lexical search algorithm for keyword-based retrieval, then combines BM25 scores with vector similarity scores using configurable weighting to produce hybrid rankings. Tokenizes text fields during indexing and performs term frequency analysis at query time. Allows tuning the balance between semantic and lexical relevance.
Unique: Combines BM25 and vector similarity in a single ranking framework with configurable weighting, avoiding the need for separate lexical and semantic search pipelines. Implements BM25 from scratch rather than wrapping an external library.
vs alternatives: Simpler than Elasticsearch for hybrid search but lacks advanced features like phrase queries, stemming, and distributed indexing. Better integrated with vector search than bolting BM25 onto a pure vector database.
Supports filtering search results using a Pinecone-compatible query syntax that allows boolean combinations of metadata predicates (equality, comparison, range, set membership). Evaluates filter expressions against metadata objects during search, returning only vectors that satisfy the filter constraints. Supports nested metadata structures and multiple filter operators.
Unique: Implements Pinecone's filter syntax natively without requiring a separate query language parser, enabling drop-in compatibility for applications already using Pinecone. Filters are evaluated in-memory against metadata objects.
vs alternatives: More compatible with Pinecone workflows than generic vector databases, but lacks the performance optimizations of Pinecone's server-side filtering and index-accelerated predicates.
Integrates with multiple embedding providers (OpenAI, Azure OpenAI, local transformer models via Transformers.js) to generate vector embeddings from text. Abstracts provider differences behind a unified interface, allowing users to swap providers without changing application code. Handles API authentication, rate limiting, and batch processing for efficiency.
Unique: Provides a unified embedding interface supporting both cloud APIs and local transformer models, allowing users to choose between cost/privacy trade-offs without code changes. Uses Transformers.js for browser-compatible local embeddings.
vs alternatives: More flexible than single-provider solutions like LangChain's OpenAI embeddings, but less comprehensive than full embedding orchestration platforms. Local embedding support is unique for a lightweight vector database.
Runs entirely in the browser using IndexedDB for persistent storage, enabling client-side vector search without a backend server. Synchronizes in-memory index with IndexedDB on updates, allowing offline search and reducing server load. Supports the same API as the Node.js version for code reuse across environments.
Unique: Provides a unified API across Node.js and browser environments using IndexedDB for persistence, enabling code sharing and offline-first architectures. Avoids the complexity of syncing client-side and server-side indices.
vs alternatives: Simpler than building separate client and server vector search implementations, but limited by browser storage quotas and IndexedDB performance compared to server-side databases.
