Posterly review
A focused LaTeX-to-poster workflow for academic conference designs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Posterly is an open-source coding-agent skill and hosted service for creating academic conference posters. It converts a paper’s LaTeX source into a single HTML/CSS poster, supports exact custom canvas dimensions, and renders the design to a print-ready PDF using headless Chromium. It is aimed at researchers and academic teams that want a structured path from paper source to a printable poster, with editable HTML source available through hosted orders.
The product’s strongest distinction is its production workflow. Before printing, command-line checks identify overflow, element alignment, styling against design tokens and palettes, and final PDF issues. MathJax supports mathematical typesetting, while the HTML/CSS output provides an editable representation rather than only a fixed export. These controls make Posterly a good fit when exact dimensions, formula rendering, and print preparation matter more than broad visual-design features. Its integration options include Claude Code, Codex, and coding agents that support skills, with web and self-hosted deployment available.
Posterly has a free open-source local skill, while its hosted service uses pay-as-you-go deposits per poster rather than subscription pricing. The GPT only plan costs a $2.5 deposit per poster and includes GPT generation, a second GPT review, and print-ready PDF plus editable HTML source after approval. The Claude + GPT plan costs a $10 deposit per poster; Claude Opus generates the poster and GPT reviews it, with the same output after approval. Choose Posterly for LaTeX-driven academic posters and controlled print output. Choose an alternative if you need a broader poster-design system or recurring subscription pricing.
