CardChat is an AAC picture communication and visual schedule app designed for people with communication difficulties, including autism, language delays, Rett syndrome, aphasia, intellectual disabilities, and muscle atrophy. 【Picture communication and sentence building】 • Tap pictures to speak and combine cards into sentences, with voice cloning in Chinese and English. • Create custom categories and cards. • Use video cards, flowcharts, and picture books. 【Multiple ways to interact】 • Eye control uses the front camera and AI algorithms, with no eye-tracking device required. • Scan mode lets you confirm selections with an external switch, by patting the screen, or by blinking, making it usable even for people with very limited muscle movement. 【Visual schedules】 Show daily routines and activity steps clearly with visual schedules and full-screen alarm reminders. 【On-device English grammar correction】 In English mode, you can enable optional on-device grammar correction to refine and complete sentences built from cards. All processing happens on your device, with no upload to a server. 【Local storage and backups】 Card data is saved within the app on your device and is not automatically uploaded to the cloud. Card backups and sharing are supported.

About

A coding platform for the whole family. Parents stay in control. Kids learn to ship real software. algo.kids is built for two audiences in one app. Parents (18+) create the account, manage billing, approve every publish, and review every Algo conversation from a dedicated dashboard. Kids ages 3 to 17 build real software by talking to Algo, an AI tutor that only discusses coding. Every conversation is logged for the parent. Zero third-party trackers in the kid app. Kids never type an email or a password. A 14-year journey from "I made it move" to "I shipped it" -- with a grown-up watching the whole way. FOUR WORLDS, ONE CONTINUOUS ARC · Wonder (ages 3 to 5). Voice-first. No reading, no typing. Kids tap and drag to remix animated stories and tap-to-play games. · Spark (ages 6 to 9). Voice plus colorful blocks. Algo builds from a prompt, the kid drags blocks to tweak. Ships mini games and animated stories. · Forge (ages 9 to 13). Real Python and JavaScript in guided chunks, with a side-by-side blocks-and-code view. Ships working web apps and interactive math toys. · Lab (ages 13 to 17). Multi-file projects. Kids architect and review AI-generated code, then deploy to a real subdomain on algo.kids. FOR PARENTS · THE GROWN-UP DASHBOARD The parent surface is a full app in itself, not a settings panel. You sign in once with your email, then use it to: · See exactly what your child built, what they typed and what Algo said back. · Search 100% of Algo's chat with your kid. Always available. · Approve or reject every Lab publish before it goes live on a real subdomain. · Pause your kid's session from your phone with one tap. The current session ends within a minute. · Receive safety alerts within five minutes when a flagged moment happens. Severity 1 to 5, category labeled, retained until you acknowledge. · Manage billing, add or remove kids, and export or delete all data from the parent screen or by email. Honored within 30 days. SAFETY POSTURE, BUILT IN · No email. No password. Kids log in with a 6-digit code you give them. · Algo only talks about coding. Off-topic gets a warm redirect. Sensitive moments route to "talk to a grown-up about that" and flag for the parent. · Algo never claims to be human. · A safety classifier runs on every input and every Algo output as a separate model pass. · Every line of kid code runs in an isolated microVM. Broken code cannot break us, or them. · No ads. No retargeting. No analytics SDKs on kid surfaces. · No kid-to-kid messaging. No DMs, no comments. Showcase wall is read-only and moderated. · No uploads from kids. No camera access. No image, voice or video uploads at launch. COPPA, GDPR-K AND BEYOND · Verifiable parental consent before any child account becomes active. · Data minimization. We collect display name, avatar color, project state and Algo prompts/replies. Birth date is scrubbed to year-only within seven days. No kid email, phone, location, photos or contacts. · Conversations stay searchable for 90 days, archived to 365, then auto-deleted unless safety-flagged. · We do not use kid conversations to train AI models. · Schools get a FERPA-aligned DPA before any student data flows. PLANS · Free tier with Wonder and Spark, a daily Algo limit and a small project cap. · Paid plans unlock all four worlds, lift the daily limit and remove the cap. · Family plan covers up to four kids with sibling leaderboards. · Studio plan for schools includes a teacher dashboard, assignment templates and SSO with Google Classroom and Microsoft Teams Education.
