Custom AI Agents

Custom AI agents that know your business and act inside it

Not a chatbot bolted onto an FAQ page. We design, build and run AI agents grounded in your own documentation and data, connected to your CRM and tools, with hard limits on what they can say and a named human on the other side of every escalation.

01 — Definition

What is a custom AI agent?

A custom AI agent is a software system that uses a large language model to complete a defined job for your business — answering questions, qualifying leads, retrieving records or triggering actions — using your own data, your own rules and your own tools. Unlike a generic chatbot, it is grounded in your content, connected to the systems you already run, and explicitly limited in what it can say and do.

OwnershipVendor's productVendor's platformYours — config, data and knowledge base

The distinction matters commercially, not just technically. A chatbot that cannot see your inventory, your pricing rules or your pipeline will deflect the questions that actually decide a sale — and every deflection is a visitor who leaves to ask a competitor instead.

02 — What we build

Eight types of custom AI agent

Pick one to see the job it does, what it connects to, where a human takes over and the metric it answers to. Most companies start with a single agent and add a second once the first is trusted.

01Customer-facing3–5 weeks

Website AI assistant

The agent most companies should build first. It answers real questions about your products, services, pricing logic and process using your own documentation — at the moment a visitor is deciding whether to contact you at all.

What it actually does
  • Answers from approved sources
  • Cites what it used
  • Compares options honestly
  • Books meetings
  • Captures contact details
Where a human takes over

Pricing exceptions, complaints, anything contractual, and any question it cannot answer from an approved source. The transcript and the visitor's context go with the handoff.

Connects to

CMS and documentation, product catalog, calendar, CRM, live chat tool.

03 — Anatomy

What's inside a custom AI agent

Six components. The model is the least interesting of them — the work that decides whether an agent is trustworthy sits in the other five.

01

Grounded knowledge base

Your documentation, policies, product data and past tickets, cleaned and structured so the agent answers from approved sources rather than guessing.

Decides accuracy
02

Tools and integrations

The specific reads and writes it is allowed: look up an order, create a lead, book a slot, open a ticket. Nothing beyond that list is available to it.

Decides usefulness
03

Guardrails and scope

Written rules on what it must not discuss, what it must never promise, and how it responds when unsure. Refusal is a designed behavior, not a failure.

Decides trust
04

Escalation path

The conditions that hand the conversation to a person, and the context that travels with it, so nobody has to ask the customer to repeat themselves.

Decides experience
05

Memory and context

What the agent remembers within a conversation and across sessions, scoped to the minimum needed and matched to your data-retention rules.

Decides continuity
06

Monitoring and analytics

Every conversation logged and reviewable, with dashboards on containment, escalations, unanswered questions and the metric the agent was built to move.

Decides improvement
04 — How we build

From scoping to a supervised pilot in six weeks

Five stages. The first two involve no building at all — most failed agent projects failed in scoping, by automating a job nobody had defined clearly.

What happens

Most agent projects fail here. We interview the people who currently do the work, read real conversations or tickets, and write a specification narrow enough to be testable. If a form or a workflow would do the job better, we say so at this stage rather than after you have paid for a build.

  • Job definition
  • Real conversation review
  • Success metric and baseline
  • Out-of-scope list
  • Risk assessment
  • Build-or-don't recommendation
You receive
  • Written agent specification
  • Success metric with baseline
  • Explicit out-of-scope list
  • Honest build recommendation

Fixed fee. Yours to keep and take elsewhere if you'd rather.

Book a scoping session

Fixed scope. You keep the agent specification and the guardrail design whatever you decide next.

05 — Use cases

Where AI agents earn their place

Stated the way we scope them: the problem, what the agent does, and the outcome we measure. Outcomes describe direction, not guaranteed numbers.

NumberFunctionProblemWhat the agent doesOutcome
01SalesHigh-intent visitors leave because a specific question went unanswered at 9pm.Answers from real product, pricing and availability data, then books the call.More qualified conversations from existing traffic.
02Lead qualificationReps spend hours on inquiries that never had budget or authority.Captures fit, need and timing conversationally, enriches the record and routes by your rules.Sales time concentrated on winnable deals.
03Customer supportThe same twenty questions consume the queue and delay the hard tickets.Resolves repeat questions instantly, opens a ticket with context when it can't.Lower first response time, fewer repetitive tickets.
04EcommerceShoppers can't tell which variant, size or bundle fits their situation.Reads the catalog and stock, compares options and explains trade-offs honestly.Fewer abandoned sessions and returns.
05Internal knowledgeNew staff interrupt senior people for answers already written down somewhere.Retrieves the right policy, process or precedent from internal documentation with citations.Faster onboarding, fewer interruptions.
06Sales enablementReps arrive at calls without account context and leave without notes.Briefs before, summarizes after, drafts follow-ups and updates the CRM record.Cleaner pipeline data, shorter admin load.
07Marketing researchCompetitor and market monitoring happens once a quarter, if at all.Watches defined sources continuously and reports what actually changed.Decisions made on current evidence.
08Content operationsProduction stalls between brief, draft and approval.Runs research and first drafts against approved briefs and voice rules, routed for human sign-off.Higher throughput at the same quality bar.
09OperationsBack-office work depends on someone remembering a manual step.Reads incoming documents, extracts fields, updates systems and flags exceptions.Fewer dropped handoffs and rework loops.
06 — Trust

How we stop an agent saying the wrong thing

Any language model can be confidently wrong. That is a design problem, not a reason to avoid agents — and it is solved with grounding, limits and logging rather than a better model.

01

Grounded answers only

The agent answers from an approved knowledge base, not from general model knowledge. If the source isn't there, it says so rather than inventing one.

02

Citations on request

Where it matters, the agent names the document or record behind its answer, so a customer or a colleague can verify it in seconds.

03

Designed refusals

A written list of topics it will not discuss and promises it will never make. Refusing well is a feature we test for, not an edge case.

04

Human escalation triggers

Explicit conditions that hand the conversation to a named person, with full context attached so nobody repeats themselves.

05

Least-privilege data access

The agent sees the minimum records needed for its job, with permissions mirroring what your systems already enforce.

06

Full conversation logging

Every exchange is stored and reviewable. Errors get traced to a source and fixed there, so the same mistake doesn't recur.

You own all of it

The agent, its configuration, its knowledge base and its conversation data are yours from day one — deployed in your accounts, restricted to the minimum data it needs, and never used to train public models.

  • Your accounts
  • Your knowledge base
  • Your conversation data
  • No public model training
  • Documented data flows
  • Exportable configuration
07 — Integrations

Built into the stack you already run

An agent that cannot reach your systems is a search box. We integrate through the APIs your platforms already expose — no migration, no forced tooling, no reselling anyone's licenses.

CRM & sales

  • HubSpot
  • Salesforce
  • Pipedrive
  • Zoho
  • Custom CRMs via API

Support & comms

  • Zendesk
  • Intercom
  • Freshdesk
  • Slack & Teams
  • Email and SMS

Web & commerce

  • WordPress
  • Shopify
  • WooCommerce
  • Headless and custom builds
  • Booking systems

Data & automation

  • GA4
  • Data warehouses
  • Zapier and Make
  • Document stores
  • Internal APIs and webhooks

Platform names are examples of systems agents commonly integrate with, not partnership or certification claims. If your stack is custom or on-premise, integration is scoped during technical discovery.

08 — Fit

The first agent differs by business model

A clinic and a 14,000-SKU retailer both want "an AI assistant" and need almost opposite things. Where you should start, by sector.

B2B & SaaS

B2B & SaaS

Long cycles and committees. The bottleneck is qualification quality and how fast a serious inquiry reaches a human, not chat volume.

09 — Why Digital Otters

Why companies choose us to build their agents

We will tell you when an agent is the wrong tool. That single habit has saved clients more money than any agent we have shipped.

01

We scope before we sell

The first deliverable is a specification and an honest recommendation — sometimes that a workflow, a form or better documentation would serve you better.

02

Marketing plus engineering

We build software and run acquisition channels. Agents sit between the two, which is exactly where single-discipline vendors struggle.

03

Guardrails as a deliverable

Refusal rules, escalation triggers and data limits are written, tested and handed over — not left as an implicit property of a prompt.

04

No platform lock-in

We build in your accounts on your stack. There is no Digital Otters subscription holding your agent hostage.

05

Measured against one number

Every agent gets a baselined metric before the build. If we can't name one, we don't recommend building.

06

We stay for the boring part

The value shows up in month three, when real conversations expose the gaps. That review cycle is where agents get genuinely good.

10 — Engagement

Three ways to start

Cost has two parts: a one-off build and a monthly figure covering model usage, hosting, monitoring and improvement. Both are scoped after discovery — quoting an agent before seeing your data would be guesswork.
