## NOAN

NOAN describes itself as fact infrastructure for agentic companies. The problem it addresses is a familiar one for teams running AI agents: the price lives in fourteen system prompts, three of which are wrong; retrieval surfaces last year's deck next to this year's; memory recalls what someone said on a call rather than what was decided. NOAN's answer is to keep your company's verified facts in one place and have every agent, app, and site read them live from a single API.

Technically, NOAN exposes a plain REST API over api.getnoan.com/v1 and an MCP server at mcp.getnoan.com/mcp. You create a project, then issue a key for each agent, app, or site, scoped to the stacks it needs. A single GET returns the latest verified version of a fact block, along with who verified it and its sources. Agents can write back, posting new versions that supersede the previous ones while keeping the lineage — and if review-on-write is enabled, those writes wait for a person to approve them before anything can read them. Around that core, NOAN handles the surrounding mechanics: classification, permissions, partner sharing, and per-key activity auditing.

The platform also ships the workspace pieces agents need day to day — a shared task board for people and agents, contacts with history and open work, notes linked to facts, and reusable assets and templates. It integrates with Claude, ChatGPT, Cursor, and other MCP clients, and supports multiple model providers because the model is a configuration choice. Beyond the tooling, NOAN publishes a startup program and grant, plus material for agencies that want to run a separate fact base per client.

**Pricing & Plans:** Paid, with a free starting point: you can start free and scale when you ship, and pricing is presented as live/usage-based in the app. API access, MCP, versioned facts, review-on-write, and scoped keys are part of the platform, with higher tiers aimed at teams and agencies running the facts layer in production. A startup program and grant are also offered.

- **Verified, versioned facts:** Each fact keeps its date, sources, and the person who verified it, so nothing is silently overwritten and agents can show the receipt behind an answer.
- **Scoped keys and permissions:** Scope one key per agent, app, or site and limit it to the stacks it needs, so the right keys read the right facts and nothing else.
- **Review on write:** Turn review on for a project or a single key so any write an agent proposes waits for a human to verify it before it can be read.
- **Time Travel:** See your entire fact base as it stood on any past date, so you can answer what was true when a decision was made.
- **Activity on the record:** Every agent action lands on one timeline, marked by the key that made it, giving you auditability across agents, apps, and sites.

**Strengths:** Solves a real and specific agent problem — grounding — instead of adding another generic chatbot; Version history, sources, and named verification make outputs auditable and defensible; Model-agnostic and accessible over both REST and MCP, so it fits many stacks; Review-on-write lets agents propose updates without letting them silently change pricing or policy

**Limitations:** The product is a new category (fact infrastructure), so new users need to absorb unfamiliar concepts before they see value; Value depends on teams actually maintaining facts, so adoption requires some process discipline; Pricing is presented as dynamic and depends on the scale you ship at; It complements rather than replaces memory or RAG layers, so it is another integration to wire up

## Perplexity

Perplexity is an AI-native answer engine and autonomous research platform designed to replace traditional keyword search and fragmented browser tab workflows. Instead of returning a ranked list of blue links, Perplexity interprets complex natural-language queries, crawls live web indexes, academic databases, financial filings, and social discussions in real time, and synthesizes direct, structured answers anchored by numbered inline citations. Beyond conversational search, the platform has evolved into a broader agentic ecosystem encompassing Perplexity Computer for autonomous multi-step tasks and the Comet AI browser assistant.

Under the hood, Perplexity orchestrates its proprietary web-grounded Sonar model family alongside frontier third-party reasoning models—allowing paid subscribers to route queries through Claude Opus 4 and Sonnet 4, OpenAI's o3-pro and GPT series, or Google's Gemini models, or run parallel evaluations via Model Council. Its Deep Research mode autonomously decomposes intricate questions, conducts dozens of iterative searches across hundreds of primary sources, and compiles exhaustive, exportable briefing reports in minutes. Users can also organize ongoing projects inside Perplexity Spaces, which fuse uploaded private documents (PDFs, CSVs, docs) with live web grounding and custom system instructions.

Perplexity serves an expansive audience ranging from students and journalists to equity analysts, legal researchers, and software engineers. Individual users can rely on the free tier for everyday fact-checking, step up to Perplexity Pro ($20/month) for daily deep research and model switching, or subscribe to Perplexity Max ($200/month) for uncapped high-compute agentic runs. Organizations adopt Enterprise Pro ($40/seat/month) and Enterprise Max ($325/seat/month) for SOC 2 compliance, zero data training guarantees, and internal knowledge connectors, while developers integrate real-time grounded citations into custom software via the Sonar REST API.

**Pricing & Plans:** Offers a permanent Free tier with unlimited Quick Searches, 3 Pro Searches per day, and 1 Deep Research query per month; Perplexity Pro costs $20/month ($200/year) and Perplexity Max costs $200/month ($2,000/year) for individuals. Team plans start at $40/seat/month ($400/seat/year) for Enterprise Pro and $325/seat/month for Enterprise Max, alongside usage-based Sonar API billing.

- **Deep Research Autonomous Reports:** Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
- **Multi-Model Routing & Model Council:** Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
- **Perplexity Spaces & Hybrid RAG:** Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
- **Perplexity Computer & Comet Assistant:** Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
- **Sonar Web-Grounded Developer API:** Exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over standard HTTP endpoints so developers can embed low-latency, live-cited web intelligence directly into third-party applications.

**Strengths:** Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.; Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.; Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.; Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

**Limitations:** The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.; Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.; Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
