OnlineGridMaker is a free browser-based tool that adds customizable grid overlays to any image — designed specifically for artists, illustrators, art students, and anyone who practices drawing from reference photos.

Why OnlineGridMaker?

Most grid tools are either too basic (fixed grid size, no customization) or require downloading desktop software. OnlineGridMaker runs entirely in your browser — no install, no signup, no image uploads. Your photos stay on your device.

Key Features

Grid Overlay — Add precise grids to any image with full control over rows, columns, line color, line thickness, and opacity.

Perspective Guides — Built-in 1-point and 2-point perspective tools for accurate architectural and object drawing.

Cell Labels — Optional row/column numbering for easy reference when transferring your sketch to paper or canvas.

Instant Download — Export your gridded image as PNG or JPG and start drawing right away.

100% Local Processing — All rendering happens in your browser using HTML5 Canvas. Your images are never uploaded to any server.

Plot Agents features and specs

  • AI-Assisted Story Development
    Plot Agents uses AI to help writers brainstorm, outline, and develop plots, which can speed up the creative process and help overcome writer's block.
  • Structured Approach to Writing
    The platform likely offers frameworks or templates for story structure, helping writers organize their narratives more systematically than starting from a blank page.
  • Time-Saving for Ideation
    By generating plot ideas and suggestions quickly, the tool can save writers significant time during the early brainstorming and outlining stages of a project.
  • Accessible Entry Point for New Writers
    For beginners who may struggle with story structure, having an AI agent to guide plot development can lower the barrier to entry for creative writing.
  • Potential for Iterative Refinement
    AI tools like this often allow users to iterate on generated content, tweaking and refining plot suggestions until they fit the writer's vision.

Possible disadvantages of Plot Agents

  • Limited Brand Recognition
    As a relatively niche or new tool, Plot Agents may lack the established reputation, community, and third-party reviews that more well-known writing tools have.
  • Potential for Generic Output
    AI-generated plots can sometimes feel formulaic or derivative, requiring significant human editing to make the story feel original and personalized.
  • Dependency Risk
    Relying heavily on AI for plot generation might hinder a writer's own creative growth and problem-solving skills over time.
  • Pricing and Value Uncertainty
    Without widespread user feedback, it's unclear whether the subscription or pricing model offers good value compared to alternative AI writing assistants.
  • Possible Learning Curve for Integration
    Incorporating AI-generated plots into an existing writing workflow or software stack may require additional adjustment and may not integrate seamlessly with other tools.
