Stop Interviewing Prompt Proxies.
Start Hiring Architects.
The Senior signal is dead. Promptster provides the telemetry you need to see the brain behind the AI.
— The Hidden Cost of Guessing
Every Wrong Hire Compounds
Technical interviews were designed for a pre-AI world. The cost of getting it wrong isn't just the hire — it's the months of lost velocity.

— How It Works
Key → Candidate → Insight
Recruiter generates a key. Candidate runs one command. Promptster captures the session. Structured signal lands in your dashboard — no setup friction on either side.
03 · Insight
Insight Lands in Your Dashboard
Every decision event flows to your dashboard in real time. When the session ends, you get a structured report: percentile score, health indicators, a one-paragraph hiring brief, and auto-generated follow-up questions.

Follow-up Questions
1. Why Redis vs. in-memory for this scale?
2. Walk me through the mutex decision.

The candidate installs promptster globally and starts their session with the key. A consent TUI shows exactly what will be captured before recording begins. Under 2 minutes from zero to live telemetry.
❯npm install -g @promptster/cli

❯promptster start PST-3K9X-7FQM
Promptster — Consent
Capturing: prompts, tool calls, diffs,
and workspace file interactions only.
NOT capturing: keystrokes, clipboard,

— The signal you're missing
Three Ways to Evaluate. One That Actually Works.
You're not getting bad signal from your current process. You're getting no signal at all. Here's the difference.
Code output + pass/fail
Traditional Assessment
You see the final diff. You get a checkmark or a failing test. You have no idea whether a senior engineer wrote it in 20 minutes or a junior spent 3 hours copy-pasting from Stack Overflow with heavy AI.
- No process visibility
- Pass/fail only
- AI indistinguishable
Video playback, keystroke heatmaps
Screen Recording
You get a video. You have to manually watch it. There's no semantic understanding — you can't query 'show me all decision points' or 'what was their exploration pattern.' It scales to exactly one reviewer-hour per candidate.
- Manual review only
- No semantic search
- No attribution

Promptster Telemetry
Every event is structured data. Attribution at the line level. Percentile rank across assessed candidates. Auto-generated hiring brief and follow-up probe questions. Consent-first — candidates see the exact capture scope before a single byte is recorded.
- Line-level attribution + percentile rank
- Health indicators + hiring brief auto-generated
- Consent-first candidate experience
— Feature Deep-Dive
Insight, Not Surveillance
Promptster captures the engineering process — the decisions that separate architects from auto-complete approvers.

Custom Import
Or import your own codebase
Point Promptster at any GitHub issue with a reproducible broken commit. We validate the SHA, generate a setup script, and add it to your private library. Assess candidates on the problems your team actually ships against.
— Trust & Privacy
Not Spyware. Here's the Diff.
Most HR tech earns the spyware label. Promptster captures process telemetry — the same data you'd put in a PR description — with explicit candidate consent and full transparency.
What We Capture
- Prompts, tool calls & file interactions within the workspace
- Shell commands run in your terminal within the workspace
- File changes made in any editor within the workspace
- Prompt strategy, iteration patterns, and revision history
- Architectural decisions and tradeoff comments
What We Don't
- Keystrokes, clipboard, or screen recordings
- Commands or files outside the assessment workspace
- Browser history or personal browsing
- Webcam, microphone, or biometrics
- Environment variables, shell history, or dotfile contents
Consent TUI
Before recording starts, candidates see a full-screen terminal UI listing every data type Promptster captures. They read it, confirm, and proceed. No fine print, no hidden telemetry.
Data Retention Controls
Configurable retention windows. Purge candidate data automatically or on request. GDPR-friendly by default.
Redaction Mode
Auto-redact secrets, tokens, PII, and API keys from session logs before they hit storage. Configurable regex rules. Coming soon.
On-Prem Deployment
Run the entire stack inside your VPC. Data never leaves your network. Available on Enterprise plans.
— What you get
Four Signals. One Candidate. 90 Minutes.
Promptster generates structured telemetry that answers the questions your interview loop takes four rounds to ask.
