Comparison

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 is 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 only 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. One was caught on a Meta phone screen when the interviewer noticed repeated screen-switching, and others were flagged on HackerRank with offers withdrawn.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.
  • No four-figure non-refundable license. A flat $14.99/month for unlimited sessions, plus a usable free plan (3 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, which is the name-based scan some proctoring platforms rely on. Pair that with OS-level screen-capture exclusion on macOS and Windows.
  • Knowledge modes and personas. Load your own context and switch knowledge modes, and tune answers to a persona built from your CV, so guidance reflects your background rather than 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.
