GOCOreal-time execution
An example GOCO program running in the editor, demonstrating the language syntax and real-time output.
Inside the IDE
One editor, from first line to leaderboard.
Write in the GOCO language, run it live, practice real problems, and see exactly where you stand.

Competitive coding · Version 1
Ranked 1v1 code battles,
built into the editor.
Compete against real opponents on algorithmic problems, climb a shared ELO ladder, and earn points you can spend to gain an edge mid-match.

Earn GOCO Points
Win matches to earn GOCO Points, then spend them on power-ups that can shift a match. More power-ups are on the way.
PointsBug BombShield
Power-ups
Bug Bomb
Launches at your opponent and scrambles their code.
Shield
Blocks an incoming Bug Bomb before it lands.
If the other player has a Shield active, the Bug Bomb is blocked.
Ranked or unranked
Ranked moves your ELO and ladder position. Unranked lets you practice with no effect on your rating.
Strict proctoring
Leave or minimize the IDE during a match and the system flags it, lowering the ELO you earn for that match.
Play with friends
Add friends inside the IDE and start a 1v1 or a timed match. Friend matches are unranked.

Only ranked matches move your ELO.

GOCO AI
An AI that learns how you code.
GOCO AI reviews your process, not just your answer. During a match it stays quiet; afterwards it walks back through how your solution evolved and gives feedback tuned to where you actually got stuck.
Captured while you workevery 10-15s
01
Context
Snapshots your code every 10 to 15 seconds during a match, without getting in your way.
02
Understanding
Reconstructs how your solution evolved, step by step, from first line to final answer.
03
Analysis
Finds where you slowed down, like ten minutes stuck on one piece of logic.
04
Feedback
Explains a stronger approach and remembers it for the next time you sit down.
Personal memory
Summaries of your sessions are stored securely and recalled by your account, so guidance keeps building on your history.
Where GOCO AI shows up
1v1 post-match
Breaks down the match and your approach once it ends.
Interview mode
Ask for an interview and it poses questions, then evaluates your answers.
Course
Explains the concept you are stuck on, in context.
Editor
Sets a challenge, then reviews the solution you write.
Coming in Version 2
Classroom and assessments
Run coding labs and exams for your whole class.
In Version 2, schools and engineering colleges will use GOCO for DSA labs and coding examinations, managed from one place.

Planned for Version 2
Build question sets
Create and add your own questions for labs and exams.
Assign work
Allocate questions to a single student or an entire classroom.
Run a classroom
Create a classroom and let students join with a code.
Monitor live
See who is solving what while an assessment is running.
Track progress
Follow course progress, with ELO and ranking as a read on ability.
Integrity flags
Get flagged when a student leaves or minimizes the IDE mid-assessment.
ELO reflects competitive coding ability, so a higher rating points to stronger problem solving. Treat it as a signal, not an exact grade.
