Custom AI tools for experts,
managed for quality.

For when 80% accuracy just isn't good enough.

All of your sources (and nothing else)

Dewey builds a private personal library of all of your knowledge and only uses your sources for answers. No web scraping, no made-up facts, no "helpful" additions from the internet. When your audience asks a question, they get your expertise — verified and cited.

Designed for your needs with strong guardrails.

We configure Dewey for your specific content, brand voice, and audience needs. Custom guardrails, ongoing optimization, and a team that knows your use case — not a dashboard you're left to figure out alone.

Expertise, made available
any way you need

From publishers to membership apps to corporate knowledge bases —
and everything in between.

Public access

Your visitors leave to Google because on-site search is broken. Dewey gives them a reason to stay—instant answers grounded in your content, with clear citations back to your work.

Members Only

Give members instant access to everything you've published—years of content, searchable and conversational. A premium feature that drives retention and enhances your membership.

Internal Team Tools

Complex products need more than FAQs. Dewey turns your documentation, training materials, and institutional knowledge into an always-available resource for your team and customers.

We integrate with dozens of platforms — WordPress, Substack, YouTube, Vimeo, Google Drive, Webflow, podcast RSS feeds and more — so your entire knowledge base, regardless of where it lives, becomes part of your custom Dewey library. Deploy it anywhere you can add JavaScript, using our search or chat templates.

Every project is unique — we design solutions around your specific use case and guardrails, so no two builds are alike. Most projects run $25-50K annually, covering the build, ongoing maintenance, and all AI usage fees. Book a Consult and we'll walk through our discovery process to scope what you need.

We handle all the heavy lifting — including keeping your knowledge library current, daily testing, and regular reporting. Some clients spend an hour or two weekly mining our reports for content opportunities. Others prefer quarterly strategy sessions. Either way, you stay in control without any daily overhead.

An AI answer engine takes a user's natural-language question, searches a defined body of content for relevant source material, and generates a cited, accurate answer grounded exclusively in that content. Unlike generic AI chatbots that pull from the open internet, an AI answer engine operates in a closed loop — it only answers from your approved content and never invents information.

Dewey serves three types of content-rich organizations: premium content publishers and expert brands with deep archives, membership communities and education platforms where members ask recurring questions that existing content already answers, and B2B SaaS or knowledge-heavy organizations where customers need self-service answers from documentation and knowledge bases.

Dewey uses multiple independent layers of hallucination prevention. Source ID validation ensures the AI can only cite content that was actually found in search results. Sufficiency gating refuses to answer when there isn't enough evidence. Correctness scoring evaluates each response against source material. And a human editorial review workflow lets editors approve every answer before it reaches end users.

A custom GPT draws from the open internet and has no mechanism for human review, citation validation, or ongoing content sync. Dewey operates in a closed loop — answers come only from your approved content, citations are validated against actual search results, content syncs automatically from 30+ platforms as you publish, and a human editorial layer ensures accuracy. Dewey is also fully white-labeled with your branding, voice, and domain.
