Thirds.ai turns reusable templates into branded PDFs and images

Summary

Thirds.ai is a template-based tool for producing branded PDFs and images without rebuilding each file manually. Users can start with a designer-made template, create a design through AI chat, paste HTML or upload an image, then save logos, colours and fonts in brand kits. Saved designs can generate invoices, quotes, menus, reports, social posts and other files while preserving the chosen layout and brand elements. The service connects to ChatGPT, Claude, Gemini, Grok, Cursor and other tools through an MCP server, and applications can create files through a REST API. Spreadsheet and CSV workflows can generate batches with one output per row, while AI assistants can fill designs using details such as names, dates and prices. The product targets marketers, agencies, small businesses, developers and AI-assisted workflows. It offers a free tier with 50 monthly credits and paid Starter, Growth and Scale plans with higher credit limits, more brand kits and larger batches. Thirds.ai distinguishes its approach from image generators by keeping editable design layers and structured text, so repeated files retain consistent wording, fonts and colours.
