## CTRLpotato

CTRLpotato is a real-time AI interview assistant built for candidates who need help thinking on their feet during live interviews, coding rounds, and online assessments. The desktop app runs quietly beside whatever meeting or test platform you are using, capturing questions from three sources: microphone audio, highlighted text, and precise screenshots of the screen. A single keyboard shortcut bundles that context together and sends it to a choice of top-tier language models, which return a short hint first and then a fuller structured answer.

The product leans heavily into discretion. It avoids taking focus from your active window, can hide itself from the operating system's task manager and activity monitor, and keeps every answer inside its own workspace rather than on a shared screen. For people who would rather not have anything on the desktop at all, a mobile mirror mode lets you scan a QR code, open a live viewer in your phone browser, and control the app remotely while your laptop screen stays clean.

Beyond live answers, CTRLpotato provides real-time transcription, session debriefs for post-interview review, and customization through uploaded resumes, job descriptions, and custom AI instructions so responses reflect your actual experience and tone. Plans range from a free tier with 10 answers through monthly subscriptions to a one-off seven-day Sprint Pass.

**Pricing & Plans:** Free tier with 10 AI answers and no credit card required; Lite at $29/month; Pro at $59/month (or $177 billed quarterly); one-time Sprint Pass at $39 for 7 days of Pro access. Refunds available on the first paid purchase with light usage.

- **Multi-source question capture:** Grab questions from live microphone audio, highlighted text, or precise screenshots of a full screen or selected region, then send them in a single action.
- **Context buffer:** Stack audio, screenshots, and text snippets like a digital clipboard so multi-part questions are answered together with full context.
- **Mobile mirror mode:** Scan a QR code to open a live viewer in your phone browser, read answers and trigger commands remotely while your desktop stays hidden during screen share.
- **Model switching:** Choose between multiple frontier and open models for speed, deep reasoning, or coding help depending on the round you are facing.
- **Personalized answers:** Upload a resume, job description, or prep notes and add custom instructions, or replace the built-in prompt entirely, to steer how the AI responds.

**Strengths:** Handles audio, text, and screenshot inputs in one context buffer; Mobile mirroring keeps the desktop clear during shared screens; Switchable access to several frontier models for reasoning or speed; Resume and job-description uploads make answers sound like you

**Limitations:** Requires a paid plan for Live Coach and premium models; Using external assistance may violate some employers' interview policies; Real-time transcription is capped by plan hours

## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies
