Duos

Duos AI · Voice & Language · Leaning · AI Assistant

Duos is an AI interview practice app that turns interview prep into a live simulation. Paste a job posting, and it builds a realistic company, team, and set of questions, then runs a voice interview that adapts to your answers. When you finish, you get a verdict, green flags and red flags, and concrete tasks to fix the patterns holding you back. No guessing.

Sensay Replicas

Sensay · Leaning · Business · Chatbot

Tenorshare AI Math

Tenorshare · Leaning

Tenorshare AI Math is a free online AI math solver that turns a typed question, a photo, or a PDF into a clear, step-by-step solution. It reads printed and handwritten problems, breaks each one into readable logic, and adds short video explanations plus practice sets so you can check whether you actually understood the method. You use it in a browser, with no install and no separate app to manage, which makes it a fast option for homework and quick concept review.

TrainZilla

TrainZilla · Productivity · Leaning

TrainZilla is an AI fitness coaching software platform for personal trainers, gym owners, and fitness studios, and it doubles as an AI fitness coach that drafts plans on your behalf. The product combines an agentic assistant that builds workout and nutrition planning drafts, a client management suite with scheduling and messaging, and business tools for trainer payments and analytics. It splits into a coach dashboard, a client mobile app for iOS and Android, and a marketplace that lists verified trainers. Every change the AI suggests waits for coach approval, so trainers stay in control of what reaches their clients.

BackEngine MCP

BackEngine, Inc. · Productivity · Leaning

BackEngine MCP is an AI customer data connector that gives AI assistants like Claude one governed connection to your customer data. It works as an MCP server for enterprises, pulling conversations from Slack, email, calls, tickets, and your CRM into structured, permissioned account memory, so tools such as Claude can answer questions and act on what they find. Sales, post-sales, and product teams use it to prep meetings, scan accounts for risk, and draft forecasts without wiring each AI tool into every system by hand.

Wondering

Wondering · Leaning

Wondering is an AI learning platform built around a single promise: help you learn what you thought you couldn't. You type in a topic, tell it a bit about your job and goals, and it builds a structured course for you. Not a playlist. Not a pile of links. A course with an order, an arc, and a finish line. The lessons are short. Most run about three minutes, which is roughly the length of a coffee break or the walk between two meetings. Each one mixes visuals, audio, and small interactive exercises instead of a wall of text. That microlearning format is the whole bet: learn a little every day and let repetition do the rest. The catalog leans heavily toward AI and adjacent skills, but the course builder will happily generate something on distributed systems, astronomy, or linear algebra if that's what you ask for. Wondering positions itself as the anti-Duolingo. There's no streak guilt, no gamified nagging, and no 47-tab dashboard. You learn a little, you practice a little, and the platform tracks what you've mastered versus what still needs review. It's aimed at working professionals who want to be the person in the room who actually understands AI, rather than collecting certificates they never use.

CoachAI

Coach AI Technologies FZE LLC · Leaning · AI Assistant

CoachAI is an iPhone fitness app that turns your phone camera into a coach. Prop it up, step back, and it counts every rep, reads your form, and calls out what to fix while you move. Workouts adapt to the reps you actually complete, and a smart nutrition plan adjusts to your goals, so the plan you follow on Tuesday isn't the static one you downloaded in January.

Poth Labs

Poth Labs · Productivity · Leaning

Poth Labs is an AI customer research platform that pulls feedback, support tickets, calls, and account data into one searchable "customer brain." Instead of waiting on a survey cycle, teams can ask a question in plain language and get an answer grounded in the evidence they already collect. It's built for product, support, and research teams who need to know why customers behave the way they do, not just that a number moved. The platform treats every answer as a claim that has to stand on a source.

Liminal

Justin Lam · Productivity · Leaning

Liminal is a collaborative workspace built for teams that work with AI agents. It's a local-first workspace: your files stay as plain Markdown and HTML on your own machine, then sync through a small CLI to a shared browser UI. Your agent writes a file, your teammates see it rendered in seconds, and their edits land back on your disk. Your workspace stays a folder. Every agent you use reads it directly.

AI YC interview with Gstack agents

Garry Tan (open-source gstack, MIT license) · Leaning · Business

AI YC interview with Gstack agents is a YC-style mock interview that drops role-based voice bots into your live Meet, Zoom, or Teams call so you can rehearse a startup pitch under real pressure. Each bot carries the persona of a gstack specialist from Garry Tan's open-source toolkit, joins as a speaking participant with an avatar, and answers or challenges you in real time. The bots run on your own local coding-agent setup, such as Claude Code, Codex, or Cursor, rather than a hosted SaaS brain.

Yoggi - AI Chat for Kids

Yoggi · Leaning · Chatbot

Yoggi - AI Chat for Kids is a kid-safe AI chatbot that changes how it talks depending on your child's age. Built for children ages 3 to 15, it answers in short, simple sentences for little ones and holds deeper conversations for teens. It works as a parental control AI app too. Voice chat, AI image generation, and a PIN-protected parents' corner round out the package, and every chat stays readable to you. Instead of cold refusals, it redirects awkward questions gently and pings you by email the moment something needs attention.
