On LinkedIn, someone described the job market as “a market I never want to visit.” It is tough, brutal, even hostile.
If you’ve been hearing “we’ve decided to move forward with another candidate,” it doesn’t mean you’re not qualified — it usually means the competition had an edge in a few key areas.
- Their skills were more closely aligned with current employer needs.
- They had more experience applying those skills in real-world settings.
- They had AI capabilities that gave them an advantage.
That’s where Cosmo comes in. CodeSignal’s new skill-building app helps you close these gaps by teaching you in-demand skills, giving you hands-on practice, and building your AI fluency so you can feel confident pursuing your next opportunity or promotion and stand out in the interview.
Turn Screen Time into (Hireable) Skill Time
Cosmo is a free-to-download (on iOS, upcoming on Android on August 28), experiential learning web and mobile platform with 300+ bite-sized courses. You can build skills in accelerating fields like business, generative AI, tech, finance, coding, leadership, data, business, and personal growth.
The course catalog caters to the current industry demands. CodeSignal, a skill assessment and learning platform, has used its data from thousands of hiring companies to understand their needs and has built courses in response to their demand.
With a monthly or yearly subscription, you can access multiple courses and get shareable certifications that you can post on LinkedIn or attach to your resume.
Let’s see how you can use Cosmo if you’re working in finance.
If you’re a finance professional looking to move into a higher-level role with more responsibility, leverage, and pay, the fastest way to stand out is to bridge the gap between finance and AI. Right now, leaders across the industry are struggling to find talent with both skill sets, and those who have them are in high demand.
On Cosmo, you can start with the GenAI in Finance course to build AI fluency in a finance context. Add Effective Leadership for Aspiring Managers to learn how to guide teams and drive change. Strengthen your analytical edge with Introduction to Data Analytics, so you can make better decisions with large, complex datasets.
Round it out with personal growth courses, and you’re not just a finance expert, you’re the forward-thinking leader companies are competing to hire.
These courses are bite-sized, but full of practice. Even if you’re a student or a recent graduate, you can accumulate skills by just spending a few minutes on Cosmo, not learning one way, but both ways.
“Cosmo makes learning hands-on from the very first tap. In five minutes, you might write a real GenAI prompt, fix a Python bug, tune an ad headline, or craft a follow-up email—small wins that stack into big career moves.”
— Tigran Sloyan, Co-Founder & CEO, CodeSignal
Build Skills That Get You Hired
Cosmo, which is available to download on iOS and Android (from August 28), has 60+ learning paths (sequential content designed to reach a goal) across industries. Let’s take a current market favorite — AI.
Cosmo’s Generative AI Courses
Professionals with AI skills are earning more, and the demand for employees with AI skills is higher.
Cosmo helps you become AI fluent — the ability to turn a task into a clear prompt, pick the right tool, and get output that matches your goal. You will learn the guardrails (privacy, bias, source checks) and use AI to get quick drafts, analysis, and for problem-solving.
Cosmo makes sure you don’t just know AI, but you use it to streamline work and drive results. Anyone can take its Gen AI courses, since it’s the top skill employers want.
- Beginners who want to write clear prompts, summarize long docs, draft better emails, research, create slides, and double-check facts
- Business and marketing professionals who want to brainstorm creative concepts, draft campaigns, segment audiences, analyze spreadsheets, and turn notes into summaries
- Technical professionals in data, product, or engineering who want to write code, run SQL queries, fix bugs, and document and refactor code
- Managers and team leads who want to write job descriptions, draft performance feedback, and model scenarios with clear assumptions and citations
- Advanced users who want to build end-to-end solutions through prompt chaining, output refinement, multi-tool integration (docs, sheets, code), and automated quality assurance
“AI-empowered education… on steroids.”
– Cosmo Learner
Cosmo’s Gen AI courses are also spread across business, sales, marketing, HR, finance, engineering, analytics, healthcare, cybersecurity, project management, and product management. And if you’re a complete beginner or a student, you’ll find courses fit for you too.

“Fun, intuitive, and keeps you locked in.”
– Cosmo Learner
Micro-Lessons Personalized for You
The courses break a skill into tiny, focused reps you can do on your phone. Craft a specific AI prompt, write a Python snippet, or identify a good marketing hook — repeat similar tasks until you absorb the skill.
Each lesson is part of a learning path that will eventually lead to subject mastery and your certification.
Throughout every course, your AI tutor provides personalized hints and guidance for what to tackle next. Cosmo is designed around hands-on learning that fits your schedule. It’s built for your convenience and your pace.
“It’s like Duolingo, but for skills that actually get you a job.”
The Big Question — What Does it Cost?
Cosmo is free to download, and you can upgrade it for faster course progress. It uses the energy method to advance through the lessons. The free version of the mobile app is limited to 10 energy per day, which lets you complete a little over one unit per day.
The upgrade costs $24.99/month or $149.99/year in the US. This will get you access to your Cosmo+ subscription on your mobile and desktop.
