## Height Estimator

Height Estimator is a web tool aimed at parents, coaches and anyone curious about growth outcomes. The child predictor asks for gender, age between 1 and 17.5 years, current height and weight, and both parents' heights, then returns an estimated adult height together with percentile context. The site says the model blends classical linear regression on parental height with the GPT-4o model, and quotes typical margins of error of roughly 5.3 cm for boys and 4.3 cm for girls.

A second mode, the Image Height Estimator, works differently: you upload a photo and the tool uses vision analysis to estimate how tall the person appears to be. The company states that uploads are not stored and that predictions are handled with privacy in mind. Users can create an account to track growth over time and compare entries against growth charts.

The service is positioned as an educational estimate rather than a medical diagnosis. The site repeatedly stresses that nutrition, sleep, hormones and overall health all influence final height, so results should be treated as a guide and discussed with a pediatrician when growth concerns are real. Typical use cases include tracking a child year over year, sanity-checking a growth chart result, or satisfying curiosity about a photo.

**Pricing & Plans:** The site presents the height predictor and image estimator as free to use, with an optional signup for tracking growth over time. No paid tier is advertised on the homepage.

- **Child height predictor:** Enter gender, age (1-17.5 years), current height and weight, and both parents' heights to get a projected adult height.
- **Image-based height estimator:** Upload a photo and let the vision model estimate the person's apparent height without manual measurements.
- **Growth tracking:** Create an account to log multiple measurements over time and see how actual growth compares with the prediction.
- **Percentile and chart context:** Results are framed with percentile ranges so you can see whether a predicted height sits in the average band.
- **Privacy-first handling:** The site states that uploaded photos and entered data are not stored on its servers.

**Strengths:** Both a data-driven child predictor and a photo-based estimator in the same free tool; Clear input flow with explanations of each field and its units; States error margins honestly instead of promising unrealistic precision; Account-based tracking makes longitudinal comparison easy

**Limitations:** Predictions are estimates and cannot replace medical assessment; The image estimator depends on photo quality, pose and lighting, so results can vary widely; Some explanatory sections are verbose and repeat similar points

## Skillry

Skillry is a curated library of Agent Skills — reusable packages of instructions, templates and scripts that AI coding agents can install and run. The concept is straightforward: give an agent a well-designed workflow, and it can produce a complete, presentable artifact rather than a rough draft. Skillry focuses on deliverables you would actually show, spanning web pages and landing pages, slide decks, images such as OG graphics, and short videos.

The key differentiator is that Skillry designs the output first. Its team art-directs a finished piece — a page, a deck, a film — then writes the original instructions, templates and scripts that let your agent reproduce that style. Each Skill page displays a real result it made, so you can see the visual point of view before installing. Skills are maintained by the same team as agents and models evolve.

Installation is agent-first. You can browse the catalog on the web, connect via MCP so your agent can search and inspect Skills, or install from the CLI. Free Skills require only a sign-in, while Premium Skills come with a Pro subscription or a one-time lifetime purchase. Model, API and rendering costs are handled by your own environment, not by Skillry.

**Pricing & Plans:** Free Skills are available with a sign-in. Pro is $9.99/month (regularly $19.90) or $79/year (regularly $158), and a Founding Lifetime plan costs $169 one-time. All paid plans include Premium Skills, MCP/CLI/web install and ongoing updates; model and rendering costs are extra.

- **Original in-house Skills:** Every Skill is designed, written and tested by the Skillry team, with templates and scripts built from a finished piece of work.
- **Multiple output types:** Skills cover web pages, slide decks, images, video and reports, so your agent can produce a range of assets.
- **Broad agent support:** Install and run Skills inside Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and more.
- **Preview before install:** Each Skill page shows a real result it generated, so you can judge the visual style before adding it.
- **Flexible installation:** Add Skills from the web, through an MCP connection or from your CLI, with browser-based authorization.

**Strengths:** Original Skills designed and maintained in-house; Covers websites, slides, images and video in one library; Works across Claude Code, Codex, Cursor and many other agents; Each Skill previews a real result before you install

**Limitations:** Full access to Premium Skills requires a paid plan; Model, API and rendering costs are separate from the subscription; The catalog is newest to market, so coverage keeps evolving
