Clickable hotspots
Draw a clickable area anywhere on a page and link it to another page in the document or to any website on the internet.
Who Tangent is for
Made for everyone making digital paper.
Three kinds of creators get the most out of Tangent. If any of them sound like you, the editor will feel like it was made for the way you already work.
-
Digital planner and workbook creators
Take your low-content interior pages, habit trackers, journals, and planners, and turn them into interactive PDFs your customers can fill in directly. Add a clickable table of contents, let readers jump between pages, and give them real form fields for moods, habits, and reflections.
-
Creators with folders of AI-generated images
ChatGPT, Gemini, and other image models now generate beautiful pages with real typography, including infographics, worksheets, and planner spreads. Tangent assembles those images into a single interactive PDF without requiring design software.
-
Anyone with a flat PDF that should do more
Add hotspots, link to URLs or other pages, build a working table of contents, drop in form fields, and export. The editor runs in your browser, so there is no install required, no monthly subscription, and the workflow is short enough to learn in a single sitting.
AI images deserve more
Your AI images deserve more than a download folder.
Current image models from OpenAI, Google, and others can generate detailed pages with accurate text layout, including planner spreads, infographics, worksheets, and study guides. The challenge is that they arrive as a stack of PNGs sitting in a folder.
Tangent assembles that stack into a single interactive PDF. Drop your images in, arrange the page order, add clickable links between them, place form fields wherever readers should write or tick, and export the finished file. The full workflow takes minutes.
Features
Everything you need to make a PDF interactive.
-
Make it clickable
Turn a flat document into a navigable one. Draw hotspots, link to URLs or other pages, and let Tangent find your table of contents for you.
- Draw link hotspots anywhere on the page using a click-and-drag tool.
- Link each hotspot to a URL or to another page in the document.
- Use automatic text detection to build a clickable table of contents in seconds.
- Apply a single link to every page at once, which works well for a persistent back-to-top link or a return-to-index button.
-
Make it fillable
Real AcroForm fields that fill in any reader, plus per-document styling so every input looks intentional.
- Add text fields for names, dates, notes, and journaling.
- Drop in checkboxes for habit trackers and to-do lists.
- Create grouped radio buttons for pick-one questions like mood, energy, and star ratings.
- Use dropdown menus when readers should choose from a structured list.
- Place calculator fields that sum, multiply, or average the values from other fields automatically.
- Style every form field across the document at once for a consistent look.
-
Make it yours
Layer images, text, and shapes anywhere on a page. Sketch directly with the freehand drawing tool, then use find and replace to keep colors and fonts consistent across the whole document.
- Place images anywhere on the page for watermarks, logos, or decorative elements.
- Add text annotations to label, caption, or comment directly on the page.
- Drop in shapes like rectangles, circles, and lines to highlight or divide content.
- Use the freehand drawing tool to sketch over the page or call attention to specific areas.
- Apply find and replace across colors and fonts so the document stays visually consistent.
-
Add a header or footer
Build a header or footer once and Tangent repeats it on every page in the document. Use it for navigation between pages or for plain text like document titles and page numbers.
- Add clickable navigation links that jump to specific pages or open external URLs.
- Place plain text in the header, the footer, or both, aligned to the left, center, or right.
- Adjust the distance from the page edge so the header or footer sits exactly where you want it.
- Choose colors that match the rest of the document for a finished look.
-
Manage your pages
Build the document with the structure you need, then reshape it whenever you want.
- Upload any combination of PDFs and images in a single project.
- Reorder pages by dragging them in the sidebar.
- Duplicate an individual page, or repeat a whole sequence of pages, which turns one weekly spread design into a full 52-week planner.
- Add blank pages or remove pages you no longer need.
