How We Organize Feedback on Rendering Projects (and Why We Created Idear.app)

In any architectural or product rendering project, there comes a point when the client starts providing feedback: “Make this wall lighter,” “Move the sofa to the right,” “Let’s try a different viewpoint in this area.” For years, we’ve managed that feedback like most studios do: screenshots with handwritten notes, endless email threads, and WhatsApp messages with photos of the screen. It works—but only until the project grows.

The problem: feedback scattered across email, WhatsApp, and PDFs

When a project has multiple review phases and several people offering their input, each comment ends up in a different place: an email with a marked-up PDF, a screenshot on WhatsApp, a voice note, or a casual comment during a video call. Multiply this by several clients and multiple renders in progress at the same time, and “where was that comment?” becomes a minor organizational nightmare. It’s easy to miss nuances, repeat changes that have already been made, or—worse—have something important left unresolved because no one noted it in the right place.

What We’ve Built: Idear.app

To address this in our own workflow, we’ve developed Idear.app, a tool designed to centralize feedback on visual projects—renders, photographs, mockups—in one place. The idea is simple: you upload the image or render, and anyone on the team or from the client’s side can leave comments pinned directly to specific points in the image, with replies, a “resolved” flag, and a version history.

No more trying to decipher hand-drawn arrows on a screenshot or searching through an email thread to find which message requested a particular change: each comment is pinned to the exact spot on the image it refers to.

How We Use It in Our Projects

In practice, we organize each project into “branches” that represent the different versions of a render or a scene. The client receives a link, logs in without having to create complicated accounts, and leaves their annotations directly on the image, point by point. We receive those comments, apply the changes, and mark them as resolved as we go, so that it’s always clear what’s pending, what’s been resolved, and on which version each comment was made.

The result is a history organized by project and version, rather than a trail of scattered messages spread across various tools.

More than just an internal tool

Although it was originally developed for our own workflow as a visualization studio, Idear.app is designed for any team or professional who manages visual reviews with clients: rendering studios, product designers, creative agencies, or anyone who needs to collect feedback on images in an organized manner.
