Whisply vs Interview Coder
Whisply and Interview Coder, two different categories
One is the original real-time Mac overlay that helps with anything on your screen. The other is a focused tool for live coding interviews. Here is how they actually differ.
Interview Coder is a coding-interview overlay. Whisply is a general-purpose Mac AI overlay that handles coding rounds, behavioral rounds, meetings, sales calls, exams, and on-screen Computer Use tasks from one menu bar app.
- Interview Coder is built around LeetCode-style coding rounds. Whisply is a general overlay that reads any window, hears any meeting, and acts on your Mac.
- Whisply ships on macOS 13 Ventura or later, Apple Silicon and Intel, with models included. No API keys to wire up, no per-call billing.
- On Pro Undetected, Whisply adds Computer Use through Accessibility permission, so the overlay can click and type for you, not just answer questions.
Whisply is the original Mac-native real-time AI overlay. It lives in the menu bar, summons on Cmd+Return, and stays out of screen sharing and screen recording by default through system-level window content protection, not a workaround layer bolted on later.

Different categories, not competitors
Interview Coder picked a specific job and went deep on it. Coding interviews. The product knows what a LeetCode prompt looks like, knows the shape of a technical screen, and is optimized around that one ritual. If your entire question is how to get through a Google or Meta coding round, that focus is a feature, not a limitation.
Whisply was built for a wider job. The overlay reads whatever is on your screen, whether that is a Karat tab, a Notion doc, a Figma file, or a Zoom grid. It listens through your own microphone, so any meeting becomes a meeting it can help with. Coding interviews are one of many things it does, alongside behavioral rounds, sales calls, customer interviews, proctored exams, and on-Mac Computer Use tasks.
So the honest framing is not which one is better. The framing is which job you are hiring the tool for. A specialist beats a generalist on its home turf. A generalist beats a specialist the moment you step outside that turf.
What Whisply actually does on your Mac
Whisply is a single menu bar app. You press Cmd+Return and the overlay appears. It can read the active window through Screen Recording permission, transcribe what is being said through Microphone permission, and on Pro Undetected it can move the cursor and type for you through Accessibility permission. That last part is Computer Use, and it changes what a real-time assistant can do in the middle of a task.
The overlay window itself uses macOS content protection at the system level. Screen sharing apps, recording software, and most proctoring frames do not capture it. That is not a clever filter on top of a normal window. It is the operating system marking the layer as protected.
Models are included. There is no BYO key setup, no monthly OpenAI bill landing in your inbox on top of a subscription, no quota anxiety in the middle of a call. Free has daily message limits and the core meeting-assist surface. Pro is 19.99 a month monthly or 11.99 a month on annual. Pro Undetected is 149.99 a month monthly or 44.99 a month on annual, and that tier adds Computer Use plus the armed proctor-resistant mode.
What Interview Coder is good at
Interview Coder is purpose-built for coding interviews and that shows. The prompt template, the output format, the muscle memory of pulling up a solution mid-round, all of it is tuned for that one situation. Engineers who only need help on coding screens often prefer a tool that does not ask them to think about anything else.
If your week is mostly Karat-style screens, HackerRank links, and CoderPad sessions, a focused product can feel less noisy. There is something honest about a tool that picks a job and refuses to wander.
Whisply does not try to argue you out of using a specialist when the specialist fits. It argues that most people doing a job hunt are also doing meetings, exams, research, and computer work, and that one overlay across all of it tends to beat a tab full of single-purpose tools.
Privacy and capture isolation
Both products understand that an overlay sitting on top of a sensitive workflow needs to be discreet. Whisply approaches that with a few specific design choices. The overlay is a system-level protected layer, so screen sharing in Zoom, Meet, Teams, and most recorders simply does not see it. There is no bot dialing into your call. Whisply listens through your Mac, not through a participant slot, which means the other people on the call are not being recorded by a third party they never invited.
On Pro Undetected, Whisply runs an armed proctor-resistant mode that works through a long list of supported proctoring environments out of the box. LockDown Browser, Safe Exam Browser, Examplify, OnVUE, VUE Lock, Prometric, Honorlock, Guardian, Proctorio, Hawkes, Inspera, LMI Rescue, Meazure, Digiexam, Exam.net, SecureBr, ProctorTrack, ProProctor, Examity, Kryterion, Surpass, NBME, and Gradescope are all covered. A separate one-time whitelist tier of 500 dollars covers TestNav, ACT, and Edvistas.
Interview Coder is generally focused on coding-screen scenarios and does not advertise the same breadth of proctor support. That is consistent with its category. It is a coding-interview tool, not an exam tool, and most coding interviews do not run inside a kiosk lockdown.
Beyond interviews, what else the overlay handles
The largest category difference is everything that happens outside an interview window. Whisply is on hand during a discovery call when the prospect asks about a competitor you forgot the pricing of. It is on hand during a customer interview when you need a follow-up question that does not sound canned. It is on hand during a billing dispute, a vendor demo, a board meeting, a podcast recording, a job reference call. The overlay does not care what app is in focus.
Computer Use lifts that even further. On Pro Undetected, the overlay can take the next action for you, not just describe it. That includes filling out forms, moving through a multi-step workflow, refactoring a file across multiple windows, or handling a repetitive task while you are on a call. Interview Coder, as a coding-round tool, does not occupy that surface.
If you only do coding interviews and never do anything else on your Mac that an AI could help with, the breadth is wasted on you. For most people, the breadth is the point.

When to pick Interview Coder
Pick Interview Coder if the only thing you need help with is live coding rounds and you want a product that is purpose-built for that one ritual. A focused tool with a clean prompt template and a workflow shaped around LeetCode-style screens is a real advantage when that is your entire problem. If you do not run meetings, do not sit proctored exams, do not need an assistant that can take actions on your Mac, and do not want a generalist on your menu bar, the specialist will feel lighter and more on-rails. Whisply is the wider tool, not the better tool for that narrow job.
Related questions
Is Whisply an Interview Coder clone?
No. Whisply is a different category. Interview Coder is a focused overlay for live coding interviews. Whisply is a general-purpose Mac AI overlay that handles coding rounds alongside behavioral interviews, sales calls, customer interviews, proctored exams on Pro Undetected, and on-Mac Computer Use through Accessibility permission. The two products overlap on the coding-interview surface and diverge everywhere else.
Can I import my Interview Coder history into Whisply?
No. Whisply does not import third-party assistant histories. Your past coding-interview sessions and prompts stay where they are. Whisply starts clean the moment you install it and only sees what you explicitly let it see through Screen Recording and Microphone permissions during a session.
Does Interview Coder work on Mac?
Interview Coder ships a desktop overlay that runs on macOS. Whisply is Mac-only by design, built for macOS 13 Ventura or later on both Apple Silicon and Intel, with a menu bar entry, Cmd+Return summon, and macOS-native window content protection on the overlay itself. If Mac-native is a hard requirement, both options can run there, but only Whisply is built exclusively for that platform.
Why does Whisply not put a bot in the call?
Because a bot in the call records every other person in the room, often without their meaningful consent, and ships that audio to a third-party cloud. Whisply listens through your own Mac instead. The other people on the call see the same participant list they always see. The assistance is private to you. That posture is core to how the product is designed, not a configuration toggle.
Does Whisply work for non-coding interviews?
Yes. Whisply treats a behavioral interview, a case study, a system-design round, a sales discovery call, a customer interview, and a board meeting the same way. It reads what is on screen, listens to what is being said, and surfaces the right answer or follow-up at the moment you need it. Interview Coder is tuned for the coding-round shape and does not lean into the rest of that surface.
Will Whisply show up in screen sharing during a coding interview?
By default, no. The Whisply overlay window is marked as protected at the macOS system level, so screen sharing in Zoom, Meet, and Teams, plus most screen recorders, do not capture it. That is content protection from the operating system, not a workaround patched on top of a normal window.
What about proctored coding assessments?
Pro Undetected ships with an armed proctor-resistant mode that works on a long list of proctoring environments out of the box, including LockDown Browser, Safe Exam Browser, Examplify, OnVUE, Honorlock, Proctorio, Inspera, Meazure, Examity, Kryterion, Surpass, NBME, and Gradescope. A separate $500 one-time whitelist tier covers TestNav, ACT, and Edvistas. Interview Coder is not positioned for that surface.
