Skills-based hiring platform for technical interviews, assessments and live coding
A multi-file IDE with whiteboard, structured scoring, private notes and code playback so interviewers can assess real problem solving rather than puzzle recall.
Automated pre-screens built from practical engineering tasks, with clear scoring that helps recruiters move qualified candidates forward faster.
AI assistants work with code context, prompts are captured, and AI reviewers rank video or code submissions against your own rubric.
Adaptive tests, activity monitoring, real-time alerts and playback reports help detect suspicious behaviour without manual review.
Build and share random generators for free with lists and simple code
Define items as lists and let Perchance pick randomly, producing names, items, prompts or full paragraphs.
Customize how your generator looks and behaves with standard web markup, styling and scripts.
Publish generators instantly so anyone can open and use them from a shareable page.
Browse and reuse generators created by the community, from RPG tools to story prompts and AI apps.
