Estimation is the meeting nobody wants and the number everyone needs.

Sprint planning takes longer than it should. Estimates vary across teams, implementation steps get missed, and delivery forecasting becomes difficult to defend as projects grow more complex.

Hours lost every sprint to estimation debates that rarely converge.

Tickets sized inconsistently across teams, which breaks roadmap forecasting.

Story breakdowns missed because the team forgot a step until the work began.

Executives and finance teams left with timelines that cannot be defended in front of the board.

EstiMate AI fixes the bit that breaks first: the number.

Faster estimates. More accurate plans. Inside the tool your developers already use.

EstiMate AI sits inside Atlassian Jira and produces a data-driven time estimate the moment a story or task is created. No tab switching, no external dashboard, no extra workflow. The number appears in the Estimation field, ready to accept or override.

EstiMate AI analyses project context, historical estimation patterns and ticket structure to generate practical estimates directly inside Jira workflows.

EstiMate AI is built and maintained by Gloster Digital, a custom software development group listed on the Budapest Stock Exchange. If the standard plugin does not fit your setup, the same team can build what does.

Why teams choose EstiMate AI over building their own forecasting model

Reason 1

Productive from day one, no ramp-up needed

EstiMate AI starts generating useful estimation suggestions immediately using historical estimation patterns and project data, without requiring a long setup or training phase.

Reason 2

Continuously learning, to match your team velocity

EstiMate AI can adapt estimation suggestions over time based on how your teams plan and deliver work across projects.

Reason 3

Seamless inside Jira

No second tool, no copy-pasting, no context switching. EstiMate AI lives inside the Jira workflow you already use. Accepting an estimate into Jira Time Tracking is a single click. Developers barely notice the plugin is running, which is exactly the point.

Reason 4

Story breakdown with reasoning

Every estimate can include a reasoning view that explains the suggested estimate and highlights potential implementation steps the team may want to consider.

How EstiMate AI works inside Jira

01 Step 1

Create a Jira story or task as usual

Create a story, bug or task inside Jira using your normal workflow. Add a short description or acceptance criteria in plain language. No new interface, migration or separate dashboard required.

02 Step 2

Review the AI-generated estimate and reasoning

EstiMate AI analyses the issue in the background and suggests a time estimate directly inside Jira. Open the reasoning view to review suggested implementation steps, estimated effort and technical considerations behind the estimate.

03 Step 3

Generate subtasks from the reasoning flow

Turn the reasoning output into actionable Jira subtasks to accelerate sprint planning and implementation. Teams can immediately review, assign and refine the generated work items inside Jira.

EstiMate AI works for every stakeholder in the estimate chain.

Developers

Less ambiguity at the start of a sprint, more consistent estimation across tickets, and far fewer planning sessions that drift past the hour.

Product owners and project managers

Reliable timelines to plan with, communicate with, and defend. Story breakdowns that catch missing steps before they become missed deadlines.

Executives and finance

Accurate resource and budget forecasting that holds up in front of the board. Estimates with a clear reasoning trail, not opinions.

Clients and stakeholders

A neutral, third-party reference point on top of what the development team proposes. Estimates everyone can agree on, faster.

In the words of teams already using EstiMate AI

EstiMate AI is a genuinely useful tool for standard development tasks, and the reasoning engine is a nice touch. For highly specialised user stories in niche domains or complex integrations, you still want expert oversight, but as a complement to existing domain knowledge it adds real value. We use it alongside Jira's own AI features to spin up new tasks and size them quickly.

Veronika Kovacs

Project Manager, Accent

Honestly, getting developers to agree on estimates used to be a nightmare. EstiMate AI does not solve every argument, but it gives us a good starting point. It is neutral, fast, and surprisingly accurate. It gives the team a faster starting point during sprint planning, especially on larger or less-defined tickets.

Emil Geredy

Senior Software Engineer, Telekom

As a Lead Developer at FinAxis Solutions, I know how much accurate estimation matters on finance projects. EstiMate AI changed how we plan. From day one the plugin produces estimates that line up with what our most experienced engineers would pick, using historical Jira data. No long learning phase. Our executives also value the clearer budget forecasts. If you are tired of the overhead of manual estimation, I would strongly recommend it.

Jason Park

Lead Developer, FinAxis Solutions

Our sprint planning sessions at BlueSky Retail used to run for hours. We now deliver more precise timelines in half the time. The plugin blends into our Jira setup so well that we barely notice it is there, and our forecasts are finally accurate. The team appreciates how it breaks complex tickets down into smaller tasks. It is essential to our budgeting and resource planning.

Sarah Wilson

Product Manager, BlueSky

Our digital marketing agency juggles multiple client projects with fast-changing priorities. EstiMate AI gives us a consistent way to predict the resource we need and balance workloads across teams, all without leaving Jira. The biggest win is the clarity: each user story comes with recommended sub-tasks that match our workflows. It has been a lifesaver for retrospectives and client communication.

Thomas Reid

Project Coordinator, KreativeSpark Agency

We work in healthcare, where accuracy is essential and deadlines are non-negotiable. EstiMate AI has transformed our planning by providing reliable estimates inside Jira. Tasks that used to take days to size are done in minutes, and the sub-task breakdowns keep our compliance team comfortable. Since installing from the Atlassian Marketplace we have seen a clear return on investment in both time and budget.

Lucas Bennett

Project Director, HealthSecure Tech

Running Jira on-premises instead of Cloud? We have a solution for that.

EstiMate AI ships first for Jira Cloud through the Atlassian Marketplace. If your organisation runs Jira Data Center, an air-gapped Jira instance, or a tightly governed deployment that the standard plugin cannot reach, Gloster Digital's engineering team can build a deployment that fits.

That includes self-hosted EstiMate AI on infrastructure you control, integration with internal identity providers and audit pipelines, and changes to the reasoning logic where your delivery model needs them. It is the same engine, configured for environments where compliance, data residency or vendor governance leave no room for the default route.

What teams ask before they install

How long does it take to install EstiMate AI?

Installation is a single click from the Atlassian Marketplace. Estimates begin appearing in the Estimation field as soon as new stories or tasks are created. There is no ramp-up phase before the plugin becomes useful.

Do we have to retrain the model on our own tickets first?

No. EstiMate AI ships with a large base of historical Jira data and produces useful estimates from day one. Over time, it can adapt to your specific team velocity, or stay on the general benchmark. The setting is per project.

Can EstiMate AI replace our developers' estimates?

No, and that is not the point. EstiMate AI works as a neutral, fast second opinion sitting next to your developers' judgement. The team chooses what to accept, what to override, and what to revisit. The plugin reduces the time teams spend discussing and validating estimates during sprint planning, so your engineers can spend it on the work only they can do.

What if we are on Jira Data Center or an air-gapped Jira?

Gloster Digital's engineering team can deliver an EstiMate AI deployment for Jira Data Center or fully air-gapped environments. Use the contact form below and we will set up a scoping call within one working day.

How is EstiMate AI priced?

Subscription-based, billed through the Atlassian Marketplace. Pricing scales with the number of Jira users on your instance, following the standard Atlassian Marketplace tier model. Custom deployments for on-premises and Data Center are quoted separately.

Where can we cancel?

Directly from your Atlassian Marketplace billing. There is no migration to undo and no data lock-in. If you cancel, the plugin simply stops generating new estimates.

Who builds and maintains EstiMate AI?

EstiMate AI is built and maintained by Gloster Digital Group Nyrt., a custom software development group listed on the Budapest Stock Exchange. Support and product development come from the same team.
