SpotCheck
A web tool and browser extension where professionals paste any AI-generated text — a client email, a report, a proposal, a marketing blurb — and get a plain-language audit flagging unsourced claims, vague-but-confident assertions, and specific facts (names, numbers, dates) to verify before sending.
Freelancers, consultants, and small-firm staff who use ChatGPT or Claude to draft client work and can't afford to ship an AI hallucination
- Claim-by-claim audit that labels each sentence as verifiable, vague, or likely fabricated, with a confidence score
- Specific red-flag callouts for invented statistics, fake citation titles, and named entities that don't exist
- 'Verify in one click' links that search Google, Wikipedia, and PubMed for the exact claim being questioned
- Browser extension that runs the same check on highlighted text in Gmail, Google Docs, and Notion without leaving the app
The Dev.to article's central insight — 'the verifier is the bottleneck, not the model' — is exactly what professionals hit every day: the AI sounds right, but the verification step is where mistakes ship. No mainstream tool serves this gap for non-engineers.
Multiple guides to ChatGPT/Claude for freelance client work exist (proposals, emails, reports) and Stanford Law / NCSC / Slaw.ca document real liability concerns about shipping hallucinated AI output to clients — confirming the pain is real and professional.ChatGPT for Freelancers: How to Save Time, Win Clients, and Deliver ↗AI, Liability, and Hallucinations in a Changing Tech and Law Environment ↗
At least three direct competitors already ship this exact use case: Verol (Chrome extension fact-checking ChatGPT/Claude/Gemini), Theia (Chrome extension verifying claims on the web), and AiTH's Twitter fact-checker — significantly tighter than the ungrounded score suggested.Verol — AI Hallucination Detector & Fact Checker - Chrome Web Store ↗Theia: Your Personal AI Fact Checker - Chrome Web Store ↗
Competitors exist as paid SaaS/extensions (Verol, Theia) showing the model is being attempted, but no public pricing/ARR data was retrievable and freelancers are notoriously price-sensitive — willingness to pay is plausible but unproven.Verol - AI Hallucination Detector & Fact Checker - Aitoolnet ↗Verol — AI Hallucination Detector & Fact Checker ↗
Hallucinations are structural to current LLMs and unlikely to disappear; legal/regulatory pressure is actively rising (Canadian Slaw article on duty of competence, Stanford Legal analysis, NCSC guidance), keeping demand durable.The Real Problem in Hallucination Cases Is Not the Failure to Verify ↗A legal practitioner's guide to AI & hallucinations ↗
Existing extensions prove the build is tractable (LLM parsing + web search verification + browser extension), but it still requires non-trivial integration work and ongoing API costs per check — middle-of-the-road build.Verol — AI Hallucination Detector & Fact Checker - Chrome Web Store ↗AiTH-Solutions/checker-twitter-fact-checker - GitHub ↗
