Plain-English Prompt to Diagram

The entire powerful engine is activated by simple, descriptive language. There's no complex syntax or coding required. Just type what you need, like "labeled plant cell cross-section for 8th grade" or "convex lens ray diagram with object between F and 2F." ConceptViz's AI interprets your instructional intent and generates a diagram that matches your specific description, turning your own verbal explanation into a perfect visual aid in seconds, saving you from endless online searches.

Visual Commenting

Click directly on any element of your live website or captured screenshot to leave contextual feedback. This eliminates the guesswork and confusing descriptions like "top left, under the nav." Comments are pinned exactly where they matter, creating a crystal-clear dialogue between creator and reviewer. You can start threaded conversations, mention team members, and ensure every piece of feedback is visually anchored to the design itself, making it impossible to misinterpret.

Multi-Breakpoint Testing

Proofapp automatically captures and presents your website at both desktop and mobile breakpoints the moment you submit a URL. This allows for comprehensive review across the most critical device types without any extra effort. Stakeholders can toggle between views and leave specific feedback for each layout, ensuring your design is polished and functional no matter how your users access it, all from a single project link.

Secure, Account-Free Sharing

Share your review projects with clients and external stakeholders via secure, expirable links.

Freelancer Client Approvals

Freelancers can present website designs to clients in a professional, centralized hub. Instead of trading messy email chains with annotated screenshots, they share a single Proofapp link. Clients click to give precise visual feedback, which the freelancer can immediately action and mark as complete. This streamlines the revision process, reduces rounds of changes, and projects a polished, efficient service that saves hours per project.

Agency Design Team Workflow

Design agencies managing multiple projects and stakeholders use Proofapp to unify internal and client feedback. Designers, project managers, and developers can all collaborate in one space, with comments pinned directly to the relevant UI element. This visual system eliminates miscommunication between departments, accelerates internal reviews, and provides a clear audit trail of client feedback for approvals, ensuring projects move forward faster and more accurately.

Marketing Campaign Reviews

Marketing teams launching new landing pages or campaign assets need quick, clear feedback from various departments (copy, design, product). Proofapp allows the whole team to review live pages visually. Comments on headlines, CTAs, and imagery are contextually clear, preventing copy edits from getting lost in a Slack thread about hero images. This results in faster iterations and higher-quality, on-brand launches.

Developer Handoff & QA

Developers can use Proofapp during the QA and handoff phase to report bugs and visual inconsistencies directly on the staging site. Instead of writing lengthy bug reports, they can pin a comment exactly where an issue occurs, attach console logs or screenshots, and tag the responsible designer or developer. This visual bug-tracking method cuts down resolution time and ensures fixes are accurate the first time.
