Assistly vs Ultracode: which should you buy? (2026)

By The Assistly team ·

Ultracode (ultracode.ai) markets itself as the only coding-interview assistant that stays "100% undetectable" — and it does get good marks for raw coding and system-design answers. But it's coding-only, sold as an expensive non-refundable "lifetime" license, and there are documented reports of users getting caught anyway. Here's how it compares to Assistly.

What Ultracode does well

For technical rounds specifically, it's capable: users credit it with strong coding and system-design answers using current top-tier models, with step-by-step "ThoughtFlow" explanations rather than just final code. It's a native Windows and macOS app, and some reviewers say it kept working after platform hotkey-detection updates that reportedly broke competitors. If LeetCode-style rounds are your entire concern, it's a serious coding tool.

Where users run into trouble

  • It's a big, non-refundable bet. The headline is a one-time "lifetime" license around $899 — but buyers report being charged anywhere from ~$650 to $1,799 for the same product, with refunds routinely denied, even for users who were caught or never used it.
  • Documented "caught" cases. Despite the undetectable marketing, forum users report being flagged — including one caught on a Meta phone screen when the interviewer noticed repeated screen-switching, and others flagged on HackerRank with offers withdrawn.
  • Reliability under pressure. Reports of lag, freezes, and crashes mid-interview, sometimes forcing a restart.
  • Coding-only. Reviewers note it's poor for behavioral interviews, with weak verbal capture — so it does nothing for recruiter screens, meetings, or sales calls.

How Assistly is different

  • Coding and system design — without the coding-only gamble. Assistly has dedicated assist modes for coding and system-design rounds, and it's a real-time copilot for behavioral interviews, meetings, and sales calls — so one tool covers everything, not just LeetCode.
  • No four-figure non-refundable license. A flat $14.99/month for unlimited sessions, plus a genuinely usable free plan (5 full sessions a month).
  • Make it yours — and harder to flag. Rename the app and swap its icon, so it doesn't show up as a recognizable assistant in the process list, Activity Monitor, or Task Manager — the exact name-based scan some proctoring platforms rely on. Pair that with OS-level screen-capture exclusion on macOS and Windows.
  • Knowledge modes + personas. Load your own context and switch knowledge modes, and tune answers to a persona built from your CV — so guidance reflects your background, not generic model output.
  • Speaker-level context, headphones, hotkeys, notes. It tracks who said what, captures the call's own audio, lets you bind your own hotkeys, and hands you a summary and action items after every session.

Which should you choose?

If you only ever face coding rounds and want to pay once for a tool tuned to them — and you're comfortable with the price spread, the no-refund policy, and the documented detection reports — Ultracode is built narrowly for that. If you want a flexible, lower-risk copilot for every kind of conversation, with invisibility plus a renamable app to dodge process scans, Assistly is the safer, cheaper, broader choice.
