## 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

## Paperguide

Paperguide has evolved from a general-purpose "chat with your PDF" study assistant into a research platform aimed squarely at rigorous evidence work. Its current centrepiece is Systematic Review: you define a protocol, run a documented search, screen abstracts and full texts with per-criterion evidence prepared by AI, resolve conflicts between two independent reviewers, and finish with verified extraction tables plus a PRISMA flow diagram generated from your own counts. The design principle is that AI prepares evidence but never casts the decisive vote — every screening call, extracted value and synthesized claim is traceable to a named source statement and a human verifier.

The rest of the product supports that workflow from the front end. AI Search answers plain-language research questions across more than 200 million peer-reviewed papers with each assertion linked to its source; the Reference Manager imports from Zotero or Mendeley, adds papers by DOI and fetches open-access PDFs automatically; Extract Data turns a stack of PDFs into a structured, cited comparison table you can export to CSV or Excel; and the Research Agent handles multi-step literature reviews up to 50 papers, organized by theme.

Paperguide also ships an AI Writer for citation-grounded drafting, an MCP integration, and a plagiarism checker, with shared team workspaces that keep papers, annotations and reviews attached to the project rather than to one person's account. It is used by academic researchers along with medical device, HEOR, pharma and government policy teams, and reports over one million researchers on the platform. Pricing runs from a free tier through Plus, Pro, Evidence Teams and custom Enterprise plans billed per seat annually.

**Pricing & Plans:** Freemium with a free plan (1,500 AI credits per month plus limited agents and reference manager) and paid per-seat tiers billed annually: Plus around $12/seat/month, Pro around $29/seat/month, Evidence Teams around $89/seat/month with dual-reviewer screening, and custom Enterprise pricing. Yearly billing advertises savings up to 41%.

- **AI Search over 200M+ papers:** Ask a research question in plain language and get a synthesized answer drawn from PubMed, arXiv, OpenAlex and Semantic Scholar, with every claim linked to its source paper.
- **Auditable Systematic Review:** Run PRISMA-style reviews with a predefined protocol, recorded screening decisions, dual independent reviewers and a conflict resolver, and a PRISMA diagram generated from your actual counts.
- **AI-native Reference Manager:** Import from Zotero or Mendeley, add papers by DOI, and get metadata and open-access PDFs fetched automatically, with annotations and notes that feed every other workflow.
- **Cited data extraction tables:** Define custom extraction columns and have AI fill them across many papers, with each value linking back to the sentence it came from, exportable to CSV or Excel.
- **Citation-grounded AI Writer:** Draft from your own library and 200M+ papers in the same document, switching between 1,000+ citation styles without manual reformatting and without invented references.

**Strengths:** Statement-level traceability: click any claim to land on the exact source sentence; Combines search, reference management, extraction and writing in one workspace; Per-criterion evidence speeds up abstract screening and improves reviewer consistency; Free tier is genuinely usable, and annual billing discounts are generous

**Limitations:** Credit-based limits can be reached quickly on heavy research-agent usage; The advanced systematic review features and dual review sit behind the pricier team tiers; It is primarily English-oriented, which may suit non-English primary research less well; Newer compliance certifications such as SOC 2 and ISO 27001 are still listed as coming soon
