Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
The memory operating system for AI agents
Multimodal retrieval and ingestion via a single API, covering PDFs, images, Word files, spreadsheets, decks, emails, HTML and URLs.
Agent trajectories are recorded as Cases, distilled into reusable Skills, and reused so performance improves over time.
Inspect, manage and edit user, group and agent memories in a dedicated Memory Bank interface.
EverMind publishes reproducible results on LoCoMo, LongMemEval and AMA alongside its memory research.
