## 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

## Numerous.ai

Numerous.ai targets a very practical gap: most teams work in spreadsheets, but most AI chat tools live in a separate browser tab. The add-on closes that gap by exposing AI as a spreadsheet function. You type a prompt in one cell, reference other cells in it, and drag the result down a column — the AI then returns a distinct answer for every row, whether that is a rewritten product description, a categorised support ticket or a normalised country name.

Because it is built for bulk use, the product emphasises cost control and reuse. Identical queries are cached rather than re-run, which keeps token consumption down across large sheets, and the pricing is expressed in characters of input and output per person rather than opaque credits. There is no need to hold your own API keys — the service manages provider access, and a single plan covers everyone on the team.

The typical audience is operations, marketing and research teams. Marketers generate ad copy variants, keyword lists and campaign structures at scale; researchers summarise, extract and classify survey or social responses; data teams clean and standardise messy inputs; product people prototype prompts and share results. Setup is a one-click add-on install for both Google Sheets and Excel, and support is handled by email from a US-based team.

**Pricing & Plans:** Paid subscription with a paid trial: 7-day trial for $1, then a per-person plan that includes 1,000,000 characters of ChatGPT input and output per person, usable in both Google Sheets and Excel. Annual billing saves around 57%. Cancel anytime and keep remaining tokens; custom plans available on request.

- **AI as a spreadsheet formula:** Use AI in any cell through a simple function — no API keys, no external chat window, no copy-paste between tabs.
- **Bulk processing with caching:** Drag a single prompt down a column to process thousands of rows, with identical queries cached so you are not charged twice for the same work.
- **Summarisation and classification:** Summarise, rewrite, extract and classify long bodies of text such as surveys, articles or social posts into clean structured columns.
- **Marketing content at scale:** Generate ad copy, keyword lists, SEO content and campaign structures directly from your sheet's own data.
- **Team-friendly plans and support:** One plan covers the whole team, results are shareable within the sheet, and priority email support is included.

**Strengths:** Works inside the tools teams already use, so no new workflow to learn; No API keys or provider accounts to set up; Query caching keeps bulk runs cost-efficient, especially across thousands of rows; One plan covers the whole team in both Google Sheets and Excel

**Limitations:** Requires a paid trial and subscription rather than a permanent free tier; Usage is capped by character allowance, which heavy bulk users can exhaust; It depends on third-party AI providers, so model behaviour and availability are outside your control
