## Arize AI

Arize is an AI engineering platform built for teams that run generative AI in production. It is split into two products: Arize AX, a managed environment for agent observability, evaluation, and experimentation, and Phoenix, an open-source tracing and evaluation library that teams can self-host when they need full data control. Both rely on OpenInference, the open-source semantic convention for generative AI tracing that the Arize team founded and that is built on OpenTelemetry.

The workflow follows three questions. Observe answers what an agent actually did by capturing every span, trace, and session; Evaluate answers whether quality is improving or regressing using span-level, trace-level, and session-level evals; Learn answers whether a proposed change will help by letting teams test prompts and harnesses before rollout. A datastore for GenAI traces (ADB) keeps data in open formats that connect to warehouses such as BigQuery, Databricks, and Snowflake, and an in-app AI engineering agent named Alyx surfaces issues and drafts review-ready fixes.

The platform integrates with dozens of models, frameworks, and tools, including OpenAI, Anthropic, Google, Amazon Bedrock, LangChain, LangGraph, LlamaIndex, CrewAI, and DSPy. Arize publishes compliance certifications including SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, and GDPR, and supports cloud, hybrid, and self-hosted deployment.

**Pricing & Plans:** Arize uses a paid model with a free entry point: teams can start free or book a demo, while enterprise-scale usage, deployment options, and support are quoted through a contact-sales process. The open-source Phoenix project is free to self-host.

- **End-to-end tracing:** Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
- **Scalable evaluation framework:** Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
- **Alyx AI engineering agent:** An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
- **Phoenix open-source toolkit:** Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
- **Warehouse-native trace storage:** ADB stores traces in open formats that connect natively to BigQuery, Databricks, or Snowflake for joint analytics with business data.

**Strengths:** Covers the full loop of observe, evaluate, and improve rather than stopping at dashboards; Backed by OpenInference and OpenTelemetry standards, limiting vendor lock-in on trace formats; Strong enterprise posture with SOC 2, ISO 27001, HIPAA, and GDPR coverage plus self-hosting options; Integrates with a very wide set of models, frameworks, and agent SDKs

**Limitations:** Self-serve pricing is not published, so cost requires a sales conversation; The breadth of features can be overwhelming for small teams shipping their first LLM feature; Full value depends on disciplined instrumentation across the whole application

## Craft

Craft is built around the idea that notes, tasks and plans shouldn't live in separate tools. Documents sit alongside embedded tasks, a calendar view, whiteboards and daily notes, so a project brief can hold its own to-do list and its own timeline. Flexible organization lets you switch between spaces for work and personal use, nested folders, tags, or structured collections that behave like lightweight databases.\n\niPhone, iPad, Mac, Vision Pro, Windows and Android apps share the same content, and offline access means you can capture ideas on a plane and refine them later. An AI assistant helps draft and rewrite text and summarize long documents, while publishing and sharing turn a page into a link you can send. Integrations extend the workspace outward: native MCP connections for Claude, ChatGPT, Claude Code, Cursor and other clients, plus an API and Apple Shortcuts, let Craft act as a hub that other tools read from and write to.\n\nCraft is free to use with a generous feature set, and a Plus subscription unlocks the full experience. The site currently lists Plus at $8 per month, discounted to $6.40 per month on an annual-style basis, with group discounts available. The app has won multiple design awards including an Apple Design Award and a Mac App of the Year title.

**Pricing & Plans:** Free plan with core features, plus a paid Plus tier (listed at $8/month, discounted to $6.40/month) with group discounts available. No credit card required to start.

- **Documents, tasks and calendar together:** Embed tasks directly inside documents and pair them with a calendar view so planning and execution stay connected.
- **Spaces, folders, tags and collections:** Choose the structure that matches your thinking — separate work and personal spaces, nested folders, tags, or database-style collections.
- **AI writing assistance:** Draft, refine, rewrite and summarize content without leaving the document.
- **Offline-first across every device:** Apps for iPhone, iPad, Mac, Vision Pro, Windows and Android with local access when you're offline.
- **Publish, share and integrate:** Publish documents as web pages and connect the workspace to Claude, ChatGPT, Cursor and other tools via MCP and API.

**Strengths:** Elegant, fast editor that works well offline on Apple and Windows devices; Unifies documents, tasks, calendar and whiteboards instead of scattering them; Strong publishing and sharing plus MCP/API integrations for automation; Received multiple design awards, including an Apple Design Award

**Limitations:** Some of the most capable features — AI, publishing and advanced structure — sit behind the Plus subscription; Very advanced relational database needs may exceed what Collections offer; The richest experience is on Apple platforms, so cross-platform teams should test Windows and Android first
