The side panel your chatbot is missing.

Prompt Prober sits beside Claude, ChatGPT and Gemini. It scores what you are about to send, pulls in context from your tabs and your screen, then checks the answer that comes back.

Local scoring stays free forever. Your first 10 eligible prompts get Premium Enhancements.

15 roles

Pick a role to see a real draft rewritten.

Raw draft

“we just launched a new analytics dashboard, can you write an email telling our free users about it?”

Prompt Prober rewrite

Write a launch email to our existing free users announcing the new analytics dashboard. Lead the subject line with the one benefit they'll care about most. Keep the body under 130 words, warm but direct, with a single call-to-action button labelled “See it live.” No emojis or exclamation marks, and end with a one-line P.S. hinting at what's coming next.

Raw draft

“can you explain what they actually did in this methods section? i'm not from this field”

Prompt Prober rewrite

Walk me through the methods section I'll paste below as if you're explaining it to a sharp reviewer from a neighbouring field. Define each technique in one plain sentence, flag any step missing a control or baseline, note whether the sample size is justified, and end with a short list of what someone would need to reproduce the study. Don't fill gaps with assumptions, flag them instead.

Raw draft

“my python function is really slow on big lists, how do i make it faster?”

Prompt Prober rewrite

I'll paste a Python function that's O(n²) and crawls on lists over ~1M items. First tell me the most likely bottleneck, then give a faster version that keeps the exact same inputs, outputs, and public signature. State the new time and space complexity, call out any new dependency or trade-off, and add a one-line note on how to confirm the behaviour is unchanged.

Raw draft

“i need a headline for our new time-tracking app's landing page”

Prompt Prober rewrite

Write 8 landing-page headlines for a time-tracking app aimed at freelance designers who feel guilty about unbilled hours. Lead with the outcome, keep each under 9 words, and mix the angles: lost income, professional pride, effortless habit. Avoid “effortless,” “seamless,” and “revolutionise,” and add one subhead option under your strongest pick.

Raw draft

“can you take a look at my landing page design and tell me what to fix?”

Prompt Prober rewrite

Critique the landing-page mockup I'll attach as a senior product designer doing a 10-minute review. Focus on visual hierarchy, contrast, spacing rhythm, and whether the primary CTA is unmistakably the most prominent element. Give me 3 concrete changes ranked by impact, one quick win I can ship today, and flag anything that fails WCAG colour-contrast.

Raw draft

“we're adding saved filters to search. can you write the user stories?”

Prompt Prober rewrite

Write 3 user stories for adding saved search filters to our dashboard, in the “As a [user], I want [x], so that [y]” format. For each, add acceptance criteria as a testable checklist, name one edge case we'd otherwise miss, and note the analytics event we should fire. Keep each small enough to ship in a single sprint.

Raw draft

“a customer is furious that we charged them twice, help me write a reply”

Prompt Prober rewrite

Draft a reply to a customer who's angry about being charged twice. Open by acknowledging the mistake plainly, with no corporate hedging, confirm the refund lands in 5-7 business days, and explain in one sentence how we'll stop it recurring. Keep it under 100 words, warm and human, never defensive, and give them a direct way to reach me if it isn't resolved.

Raw draft

“here's my startup pitch, can you make it better for investors?”

Prompt Prober rewrite

Pressure-test the 30-second pitch I'll paste for my B2B scheduling tool. First, ask me the 5 toughest questions a seed-stage investor would ask after hearing it. Then rewrite the pitch so it pre-empts the two biggest objections, makes the market size concrete, and ends on traction. Jargon-free and under 90 words, so I can say it in one breath.

Raw draft

“i've got a few findings from our analysis, can you turn them into a slide for the client?”

Prompt Prober rewrite

Turn the four findings I'll paste into a single executive slide. Give me one headline insight (the “so what”), three supporting bullets of 12 words or fewer, and a recommended next step with a rough effort flag. The audience is a non-technical COO deciding whether to fund the project, so cut anything that doesn't change their decision.

Raw draft

“this prospect went quiet after the demo, what should i send them?”

Prompt Prober rewrite

Write a follow-up email to a prospect who went quiet two weeks after a demo. Reference the specific problem they raised, that onboarding takes their team too long, and lead with a concrete way we shorten it. Offer one easy next step (a 15-minute call or a shared doc), keep it to four sentences, and don't sound needy or guilt-trippy.

Raw draft

“help me understand this economics paper for my midterm”

Prompt Prober rewrite

Break down the core argument of the economics paper I'll paste into 3 intuitive analogies. Explain the key regression equation without jargon, identify the paper's main counter-argument, and give me 2 potential exam questions based on its conclusions.

Raw draft

“review this nda and tell me what's unusual”

Prompt Prober rewrite

Audit the attached Non-Disclosure Agreement for non-standard indemnity clauses, overly broad definitions of Confidential Information, and perpetual survival obligations. Present findings in a 3-column risk matrix: Clause, Concern, Recommended Redline.

Raw draft

“how do i architect this event-driven pipeline?”

Prompt Prober rewrite

Draft an architecture RFC for a high-throughput event pipeline processing 50k events/sec. Compare Kafka vs AWS Kinesis for partition rebalancing, document the dead-letter queue retry policy, and outline end-to-end telemetry requirements.

Raw draft

“write standard operating procedures for vendor onboarding”

Prompt Prober rewrite

Draft a 4-step Standard Operating Procedure for onboarding new enterprise SaaS vendors. Include security compliance validation (SOC2/ISO27001), finance approval sign-offs, and an emergency SLA escalation tree.

Raw draft

“write an outreach message to a senior backend engineer”

Prompt Prober rewrite

Draft a personalised 90-word outreach message to a Senior Distributed Systems Engineer on LinkedIn. Mention their recent blog post on Raft consensus, explain why our real-time streaming challenge is unique, and offer a no-pressure 15-minute sync with the VP of Engineering.

The panel, up close.

FAQ
Which AI chatbots does it work with?

Today: claude.ai, chatgpt.com and gemini.google.com in Chrome or Edge, with support for any AI chatbot. The rewrite lands inside your conversation tab, so you stay where you work.

What actually gets sent anywhere?

Local scoring and rewriting never leave your device. Only a Premium Enhancement, Snapcopy analysis or Response Grounding check is sent to our managed service, then discarded. History is text-only and stays in your browser.

Do you train AI models on my prompts?

No. We do not use your content for training and we do not sell it. The privacy posture above is the whole policy in plain language.

What happens when the free allowance runs out?

You drop back to local mode, which keeps working forever, and the panel says exactly what changed. Premium provides 300 managed Premium Enhancements and Snapcopy analyses per calendar month, plus Response Grounding.
