It knows your application
Nestor is connected to your tool’s code and configured by our engineers: sensitive areas, tests to pass, approval rules. Nothing for your users to install.
Nestor is an AI agent built by Apptitude. It works like a member of your team: you explain what you want to change, in writing or verbally: a field to add, an approval workflow to adjust, a dashboard to create. It asks its questions, prepares the change and shows it to you before your users see it. You decide when it goes live, without writing a line of code. When a request calls for it, Nestor brings in our experts.
In a business tool, the smallest change follows the same path as a major project: request, estimate, scheduling. Your teams wait and the budget goes on simple tasks. Nestor takes on these changes with you, and our teams focus on the work that needs their expertise.
Claude or ChatGPT can suggest code. You then have to understand it, integrate it into your tool, test it and release it yourself. Nestor handles that whole journey. Our engineers connect it to your application, whether it was built by Apptitude or by another team, and configure it for it.

Nestor prepares every change on a copy of your tool, checks that everything still works and screens it for security flaws. You receive a result ready to try.
Once your team gives the go-ahead, Nestor releases the change through your usual pipeline. For 7 days, one click is enough to roll back.
When a request calls for it, an Apptitude engineer reviews or takes over the change. You are never left alone with the AI.
Nestor handles every kind of request, from the simplest to the most complex. Before starting, it assesses the complexity and chooses the right path. When needed, Apptitude’s engineers work alongside it. Choose a level or an example to see how it works.

Get a proposalNo. Nestor is a separate service with its own web interface. Our engineers connect it to your application’s source code and release pipeline. Every change follows that usual path, like a developer’s would. The code it produces belongs to you and works without Nestor.
A coding assistant is built for developers: you need to read code, check tests and handle releases yourself. Nestor is built for business teams. It knows your application, follows the rules set by our engineers, tests every change on a copy, has it approved by your team and brings in an Apptitude engineer whenever the request calls for it.
Nestor works with web applications, whether they were built by Apptitude or by another team. Mobile apps will follow. Get in touch: we check your tool’s compatibility with you and our engineers set Nestor up for you.
