LangChain vs LlamaIndex: Agents, RAG and Search

Compare LangChain and LangGraph for application orchestration, and LlamaIndex for data and retrieval needs. Their capabilities overlap, so the choice depends on your workflow and source corpus. Evaluate retrieval quality, permissions, persistent state and recovery with the same examples before choosing one stack or combining them.

How to Hire an AI Developer: A Founder’s Practical Guide

To hire an AI developer, first define what your product needs to do, then ask candidates to show relevant working software and explain their responsibility for it. Compare a freelancer, employee or development team by the work they can own, including testing and support after launch. A convincing demo should start that conversation; evidence of delivery should decide it. AI products & intelligent search Turn one product workflow into a working application ...

AI Agent Security: Permissions, Tools and Human Review

AI agent security starts with deciding which data the application may read and which actions it may take. Constrain tools, separate untrusted content from instructions and require approval where a mistake is costly. This guide turns those boundaries into implementation checks and a proposed pilot evaluation.

AI Agent Examples for Product and Operations Teams

Useful AI agent examples start with a specific task, reliable inputs and a clear limit on what the system may do. The four workflows below are illustrative designs for product and operations teams. Each includes data needs, human approval and evaluation criteria; they are not reported customer results.

AI Agent Platforms: Compare Tools, Costs & Build Options

The right AI agent platform depends on where your workflow lives, what it can change, and who will operate it. For a Microsoft-based internal workflow, start by evaluating Copilot Studio. For a custom product, compare managed cloud infrastructure with code-first frameworks. Then test each candidate against the same real task, including permissions, human approval, failures, and operating cost.

AI Agent Frameworks: Choose a Stack for Your Product

Choose an AI agent framework by the state, tools and review steps your product needs. A fixed workflow may need only application code; a retrieval assistant may need a data layer more than multiple agents. This guide compares those choices and the evidence to request before committing to a stack. AI products & intelligent search Turn one product workflow into a working application ...

No-Code AI Agent Builders: When to Buy or Build

Use a no-code AI agent builder when its interface, connectors and controls fit your workflow. Compare custom development when you need behavior, source permissions or a product interface the platform cannot support cleanly. Evaluate the complete operating cost and ownership of either route before buying.

About Arsum's Guides

Arsum publishes these guides for teams planning AI products and intelligent search systems. The organization byline identifies the publisher, rather than a named independent reviewer. The guides use AI assistance for drafting, synthesis and content checks. Technical references, proposed evaluation methods and illustrative calculations serve different purposes; hypothetical examples are not reported customer results. Read the editorial policy for the source and correction standards. Learn about Arsum, explore AI product development and intelligent search, or read the Attuned Health case study.

Editorial Policy

Arsum publishes guides for founders, product leaders, CTOs and engineering teams commissioning AI applications and intelligent search systems. Sources and claims Technical claims should link to relevant first-party documentation. Vendor documentation describes intended capabilities; it is not an independent performance benchmark. Comparisons and suggested scorecards are editorial decision aids and should be tested on the reader’s own data. Worked calculations and hypothetical workflows are labeled as illustrative. They are not client results, market averages, audited savings or delivery guarantees. Arsum’s stated target budget for an initial engagement is a commercial preference; a proposal determines the actual scope and price. ...
