Every other coach only sees its own website. OmniCode rides along on LeetCode, NeetCode, HackerRank and ten more — so it's the only one that knows what you actually know, and what you've never once practised.
Works where you already practise
A solve counter goes up. A streak stays alive. Neither tells you whether you'd recognise a monotonic stack under pressure, or that you haven't touched topological sort in four months — or ever.
And when an AI just hands you the answer, the counter still goes up. That's the trap: it feels like progress while quietly making you worse.
Problems solved. Days in a row. Percentage of a list completed. All easy to count, none of it evidence you learned anything.
Which patterns you recognise unaided, which ones you keep missing, which are going stale, and which you've never met — across every site you use.
This is the real mechanic, not a video. Click through it — stop the moment you can take it from here.
Most people stop at step 2. That's the point — the goal is to need it less, not more.
Not because they haven't thought of it — because they only ever see their own website. We're an overlay, so we see all of them.

Comparison reflects typical behaviour at time of writing. OmniCode is not affiliated with any of these products.
One mastery score per pattern, stitched across every site. It knows you solved sliding-window on LeetCode last week, and says so when the same pattern turns up on NeetCode in disguise. Scores decay, so "mastered in March" reads as going stale.
Not a syllabus. When the coach catches you missing a pattern, it queues that pattern and brings it back days later as a different problem — so you re-test the skill instead of recalling an answer.
Five minutes without a keystroke and the lightbulb blinks — once, and only if you're actually looking at the page. Say "not now" and it goes quiet for ten minutes. It asks; it never takes over.
Athletes review the tape; you get pass/fail. OmniCode replays the shape of the attempt: "you started typing within 30 seconds, then stalled for six minutes — a sign of coding before the approach was settled."
Every problem you touch quietly updates it. No self-assessment, no quiz: the score comes from whether you needed a hint, how deep you went, and whether the same mistake keeps coming back.
A single-site coach can only ever say "you've done 40 problems here."
Weakest first — the thing worth working on, not a leaderboard.
Hints are layered and effort-gated on purpose. In-person, no-AI interviews are coming back precisely because tools that answer for you leave people unable to think. We're the opposite bet.
API keys, tokens and passwords are stripped server-side before anything reaches a model. Session replays record how long your code was, never what it said. Turn code sharing off entirely and still get coached.
Every claim cites logged evidence. With too little data it says "unproven" rather than guessing — an honest distinction most trackers skip.
Free tier included, no card required. The coach appears where you already work — nothing to configure.
