Custom AI agent development for businesses

An AI agent takes a task from start to finish: it reads a request, looks things up in your tools, prepares the work and submits it to you before acting. From our studio in Ajaccio, Corsica, Step By Step builds custom AI agents with a clear scope, connected to your software and fully traceable.

Understanding

What is an AI agent made of?

An AI agent combines a large language model with tools, memory and rules. The model does the reasoning; everything else frames what it is allowed to do. These are the six building blocks we assemble for every agent.

  • A goal

    The agent is given a mission in plain language: “prepare reminders for overdue invoices”, “put this application file together”.

  • A plan

    The language model breaks the mission into steps, picks the tool for each one and adjusts what comes next based on what it finds.

  • Tools

    Every action goes through an explicitly authorised tool: reading a database, calling an API, an MCP server, generating a document.

  • Memory

    Internal rules, special cases and useful history are stored and fed back to the agent, so it does not start from scratch every time.

  • An approval point

    Before any action that commits you (sending, paying, changing records), the agent presents its work and waits for an authorised person.

  • An audit trail

    Every step, tool call and decision is logged: you always know what the agent did and why.

Use cases

AI agents for business: which tasks should you hand over?

AI agents are most useful for varied tasks that require cross-checking several sources and applying rules, but that come round often enough to justify the investment. These are the most common missions.

  • Payment reminders and follow-up

    Spot overdue invoices, check the history of exchanges and prepare personalised reminders, ready for sign-off.

  • Case file preparation

    Gather the documents for a file, check they are complete and consistent, list what is missing and draft the request for it.

  • Quote preparation

    Read a customer request, find the applicable references and terms, and pre-fill a quote in your management software.

  • Handling incoming requests

    Qualify a request, look up the customer record, suggest a reply and create the matching task in the right tool.

  • Checks and reconciliations

    Compare two sources (bank statement and ledger, order and delivery) and produce an exact list of discrepancies to review.

  • IT operations

    Server inventory, diagnostics or updates, with each command shown for approval before it runs.

Comparison

AI agent or traditional automation: what is the difference?

Traditional automation runs a fixed workflow; an AI agent pursues a goal and chooses its own steps. The two complement each other, and the table below helps you decide which suits your task.

Guardrails

An AI agent that is safe by design

An agent’s safety does not rely on the model’s good intentions but on its architecture: what the agent cannot reach, it cannot change. We apply four principles to every build.

Least privilege

The agent can only reach the tools and data its mission requires, with read-only access wherever possible.

Declared scope

Authorised folders, applications and websites are listed upfront; the model cannot widen that scope on its own.

Approved actions

Irreversible or binding actions go through human approval, presented in a clear, checkable way.

Minimised data

Only the relevant excerpt is sent to the model, and sensitive data can be anonymised before it leaves with AIGuard.

Our software

AIKeep: a ready-made AI agent, installed on your premises

AIKeep, the software published by the studio, applies these principles across the whole business: installed on your Windows workstations, it runs accounting, banking, documents, applications and servers from plain-language instructions.

  • Four ways in: APIs and MCP, browser, sandboxed Python, SSH administration
  • Supervised mode: every system command approved before it runs
  • Runs on your machines, with data encrypted at rest

Method

How we build your AI agent

Building an AI agent starts with a well-chosen mission and ends with ongoing supervision. In between, evaluation on real cases decides whether it goes live.

  1. Pick the mission

    A specific, frequent, time-consuming task where you can say what a job well done looks like.

  2. Set the boundaries

    Accessible tools, authorised data, forbidden actions and approval points: the agent cannot step outside them.

  3. Build and evaluate

    The agent is developed, tested on real cases and on trick cases, and its quality measured before go-live.

  4. Go live and supervise

    Gradual roll-out, regular review of the log, refined instructions and extension to further missions.

FAQ

Frequently asked questions about AI agents

What is an AI agent?

An AI agent is a program built on a large language model that receives a goal, decides which steps will get it there and uses tools (databases, software, documents) to carry them out. Unlike a chatbot, it acts; unlike a script, it adapts to the situation.

Can an AI agent act without supervision?

It should not, and we do not design them that way. Every agent has a limited scope, explicitly authorised tools and approval points: before sending, paying or making a significant change, it presents its work and waits for a person to agree.

Which software can an AI agent use?

Any software that exposes an API or an MCP (Model Context Protocol) server can be connected to the agent. For services with no interface, the agent can drive a browser on authorised domains. Where a connector is missing, we build it.

How is an AI agent different from traditional automation?

Traditional automation follows a fixed workflow: efficient for simple flows, fragile when something unexpected happens. An AI agent reasons from a goal and chooses its steps. The two are often combined: automation for volume, an agent for the cases that need judgement.

How do you know an AI agent is doing a good job?

Through evaluation and the audit trail. Before go-live, the agent is tested against a set of real cases with known answers. Afterwards, every action is logged and quality indicators are tracked; errors are used to refine its instructions.

Which AI models do you use for your agents?

We choose the model for the task, the cost and the provider’s guarantees, including no training on your data. Our agents and our AIKeep software rely on Anthropic’s Claude models, for example. The architecture lets you change model without rebuilding everything.
