Polymorph

Freemium

iPhone and Mac app that measures your AI usage in tokens, API-rate cost and water, without judging it.

Key features

  • Automatic Measurement: Mac reads local AI tool logs and iPhone uses Screen Time, so there is nothing to count manually.
  • Evening Check-In: A one-tap daily confirmation of personal versus work AI use, with adjustments allowed.
  • Pixel Calendar: Each day becomes a pixel colored against your own average, with streaks and a full-year band.
  • Usage and Cost (Premium): Tokens, the API-rate cost and estimated water use over today, 30 days and full history.
  • Codex Quotas and Widgets (Premium): Quota countdowns plus USAGE and LIMITS widgets.
  • Milestones and Friends: 62 milestones and friend trends via QR code or link with no account needed.
  • Private by Design: Data stays on device and in your iCloud, with no conversation read and no ads or tracking.

Best for

  • Self-Awareness: See how much you rely on AI day to day without being blocked or lectured.
  • Cost Tracking: Estimate what your token use would cost at API rates.
  • Environmental Awareness: View an estimate of the water behind your AI usage.
  • Work-Life Separation: Separate personal AI use from work-hours use.
  • Quota Planning: Watch Codex limits and reset countdowns to avoid wasting capacity.
  • Group Accountability: Compare trends with friends without sharing exact numbers.

Weaviate

Weaviate

Freemium

Open-source, cloud-native vector database that combines vector similarity search with structured filtering for scalable semantic search.

Key features

  • Vector + Structured Filtering: Stores both objects and vectors to allow combining semantic nearest-neighbor search with exact keyword and structured filters in the same query for precise, context-aware retrieval.
  • Retrieval‑Augmented Workflows & Reranking: Built-in support for RAG patterns and reranking pipelines so results can be retrieved by vector similarity, filtered, and then re-scored to improve LLM responses and reduce hallucination.
  • High‑Performance Nearest‑Neighbor Search: Core engine optimized for low-latency k-NN queries (e.g., 10-NN on millions of objects in milliseconds), enabling real-time semantic search at scale.
  • Multiple APIs & Client Libraries: Exposes GraphQL and REST APIs (plus gRPC in newer releases) and provides official client libraries across popular languages to simplify integration into applications.
  • Modular Vectorization & Extensibility: Supports pluggable vectorizers and modules so teams can use built-in models or integrate custom ML/embedding models for text, images, and multimodal data.
  • Cloud‑Native Scalability & Fault Tolerance: Designed to run as a distributed, cloud-native service with scalability and fault tolerance suitable for production deployments.
  • Embedded & Container Deployment Options: Offers Embedded deployment models and Docker-based setups for local or application-embedded instances, enabling flexible hosting options.
  • Single Query Pipeline: Allows combining vector search, filtering, and reranking in a single query call to simplify application logic and reduce round trips.
  • Stores objects and vectors together for combined vector similarity and structured filtering
  • APIs: GraphQL and REST (primary), gRPC available since v1.23 for lower latency
  • Client libraries for multiple languages (official and community-supported)
  • Retrieval-Augmented Generation (RAG) and reranking within query pipeline
  • Built-in vectorization using ML models with support for custom models
  • Cloud-native deployments via Docker and Kubernetes; managed cloud options available
  • Embedded Weaviate mode (runs inside application; experimental and not supported on Windows)
  • High-performance nearest-neighbor search (benchmarks: ms-level 10-NN on millions of objects)
  • Open-source BSD-3-Clause license with active GitHub ecosystem and examples

Best for

  • Retrieval‑Augmented Generation: Serve as the retrieval layer for LLM applications, returning relevant documents or passages to reduce hallucinations and supply context for prompts.
  • Semantic Search & QA: Implement natural-language search over large text or multimodal corpora (documents, web content, images) with relevance ranking and structured filtering.
  • Recommendation Engines: Use vector similarity on user/item embeddings combined with metadata filters to generate personalized recommendations at scale.
  • Chatbots & Conversational Agents: Power context-aware chat experiences by retrieving relevant context snippets, conversation history, and knowledge base entries for each query.
  • Image & Multimodal Search: Index and search images or mixed media using embeddings to enable visual search or cross-modal retrieval (e.g., image-to-text matching).
  • Content Classification & Tagging: Retrieve semantically similar examples to support automated labeling, classification, or moderation workflows.
  • Application‑Embedded Databases: Run Embedded Weaviate within an application or containerized deployment for local low-latency semantic search without a separate server.
  • Retrieval-Augmented Generation systems and RAG pipelines
  • Semantic text and image search over large corpora
  • Recommendation engines based on vector similarity and structured filters
  • Chatbots and question-answering layered with retrieval and LLMs
  • Content classification, tagging, and semantic analytics
