## About ApexCalc

ApexCalc is a free web platform that gathers calculators across more than 50 disciplines, including medicine, engineering, finance, science, law, and sports and fitness. The site lists over 11,600 tools, which can be searched or browsed by category and opened in the browser without signing up or installing anything.

Each calculator opens on its own page. The site says its tools include formula logic, sourced citations and links to related tools. It also lists regional finance, tax, mortgage and legal tools for 150 countries, alongside everyday calculators such as BMI and mortgage tools.

The platform is aimed at students, professionals and anyone who needs a quick answer in a specific field. The site states that every calculator is free with no account required. It also describes paid tiers for saved bookmarks, PDF export and API access, but these are marked as coming soon and are not yet available.

## About Simpled.ai

Simpled.ai is an AI explainer video maker. You type a plain-English prompt or upload a PDF, Word or PowerPoint file, and it generates a narrated explainer video in one of two visual styles. The Whiteboard style draws each scene by hand in black ink on a white board, line by line, in sync with the narration. The Science Explainer style produces flat, bold-colour animation with diagrams that build and move, along with narration and sound design. The AI writes the script, draws or animates each scene, and adds narration, so there is no timeline to edit and no storyboard to draw.

The tool narrates in 29 languages and exports in 16:9 or 9:16 at HD resolution. Videos can be downloaded as MP4 or embedded in an LMS, website, YouTube channel or sales deck. Whiteboard videos can carry a logo watermark, and a bilingual mode narrates in one language while showing on-screen text in another. Each minute of generated video costs one credit.

Simpled.ai is aimed at people who need to explain something rather than animators. Teams use it for employee training, onboarding, internal communication, sales enablement, marketing and ad creative, classroom and course content, and patient education. Enterprise plans add SOC 2 Type II and HIPAA compliance, SSO/SAML, a custom DPA and MSA, and a dedicated account manager.
