Postr is a free poster editor built for researchers. Pick a template, write with guidance, check your figures, share a link for comments, and export. No design skills needed, no paywall.
Smart templates: conference-ready layouts with discipline-specific palettes, and APA, SfN and ECNP size presets built in.
Figure readability: paste your R or Python plotting code and see whether the axis labels will still be readable at print size, with a copy-ready fix.
Writing guide: section-by-section tips, word count targets, and a checklist to follow from intro to conclusion.
