Postr is a free academic poster editor for students and researchers. It exists because the usual tools were built for something else.
Enter institutions once, then click to assign them to authors. Superscript numbering stays in sync when you add or remove an affiliation.
Export a .bib from your reference manager and drop it in. Postr reads BibTeX, RIS and EndNote files and formats the reference list for you.
Every poster starts at a real print size, so what you see on screen is what the print shop produces.
