Pair Companion identifies the task
It separates coding problems, multiple-choice questionnaires, system-design prompts, and ordinary conversation before choosing a response format.
AI assistance for technical interviews
Technical interviews move fast.
Keep your reasoning clear.
Pair Companion follows the question, understands the screen, and gives you a natural first sentence while a complete, explainable answer streams in behind it.
For preparation, mock interviews, and interviews where assistance is permitted. Requires your own Claude Code or Codex subscription; Pair Companion adds no AI usage fee.

“I’d start by clarifying the expected scale and consistency requirements, because those decisions shape the storage model and the write path.”
Approach
Confirm constraints, describe the simple design first, then add scaling and failure-handling tradeoffs.
Next
Walk through the data model, API boundaries, bottlenecks, and the signals you would monitor.

A usable answer, sooner
Start speaking naturally while the deeper answer develops.
The fast opening buys you time without sounding like filler. The full response stays visible and is not replaced just because the interviewer speaks again.
A short opener arrives first
A faster model produces one grounded sentence you can use immediately instead of waiting silently for the entire answer.
The complete answer streams in
A stronger model develops the approach, tradeoffs, complexity, code, and likely follow-ups while preserving the answer you are reading.
You stay in control
Move between earlier and newer answers, pause automatic suggestions, or ask for a fresh answer using the final conversation context.
Coding challenges
Code you can explain, not just copy.
Pair Companion can use a sequence of screenshots when the whole problem does not fit on one screen, then produce an interview-sized solution in your selected language.
Understands the screen
Classifies the content before answering, so a questionnaire gets direct choices and a coding challenge gets an algorithm and implementation.
Screen classificationExplains the approach
Starts with a concise way to describe how you will begin, then covers tradeoffs and complexity without pretending every detail is memorized.
Speakable reasoningComments like a walkthrough
Code comments are written in natural English as if you were guiding the interviewer, including what short variables such as n represent.
Explainable codeBuild the answer from requirements to tradeoffs.
Keep scale, consistency, availability, data flow, failure modes, and observability connected to what the interviewer actually asked.
“Before choosing the database, I’d confirm whether the read path can tolerate stale data.”
Use your own experience without sounding scripted.
Your profile, résumé, preferred answers, and the current job description help generate grounded stories. STAR is used when it improves a complex answer, not as a rigid template.
“The situation was a schema migration affecting millions of product pages, so my first priority was a safe rollout path.”
Context that survives follow-ups
The next question does not start from zero.
Pair Companion keeps the relevant conversation, the answer you are currently reading, your profile, and the role context separated but available.
- Preserves the current answer while preparing the next one
- Uses final conversation context when you request an answer manually
- Lets you navigate previous and next answers by shortcut
- Supports Claude Code and Codex through their local login
Private by design
Your interview context does not pass through our licensing server.
Screenshots, transcripts, prompts, and responses stay on your computer or go directly to the AI provider you selected. Pair Companion never asks for an AI API key and never resells model usage.

Technical interview FAQ
Know what to expect before the call.
Does the 7-Day Pass have fewer features?
No. It includes the same product features as Monthly and Annual. Only the access period and renewal model are different.
Does Pair Companion include Claude or ChatGPT?
No. It uses your locally authenticated Claude Code or Codex installation, so you need an active subscription with Anthropic or OpenAI. Pair Companion does not add model API charges.
Can it solve a problem that spans multiple screens?
Yes. Add multiple screenshots as pages, then analyze them together once the complete prompt is captured.
Can I choose the programming language?
Yes. Set the language used for generated code in the app settings.
Can I use it in any interview?
You are responsible for following the interviewer’s instructions, the platform rules, and applicable policies. Pair Companion is also designed for mock interviews, preparation, and take-home challenges.
