In plain English

Inter is a free, open-source typeface, a carefully designed set of letters and symbols, built specifically for reading on computer screens. The problem it solves is legibility: reading text on a screen is harder than on paper, especially at small sizes, so Inter was engineered with a tall x-height (meaning lowercase letters are proportionally larger) and fine-tuned details to stay sharp and clear across different screen densities. It is a variable font, which means a single font file contains the full range of weights from Thin to Black, including italics, so you can make text lighter or heavier without downloading separate files. It also includes practical OpenType features like a slashed zero (to avoid confusing "0" with the letter "o") and tabular numbers (for clean alignment in tables and data). The font is available as downloadable files, via an npm package, via Homebrew, and from a CDN for web pages. Notable users include Figma, Mozilla, NASA, GitLab, and Unity. You would use Inter any time you need a clean, readable sans-serif font for a website, app, or design tool. It is free to use commercially under the SIL Open Font License.
