## ProofUp

ProofUp is a tenant screening platform built for multifamily property operators who need to confirm that an applicant can actually pay the rent. Instead of trusting whatever pay stub gets uploaded, it verifies income directly: applicants connect their bank and payroll accounts through Plaid, and earnings are read from the account rather than from a document. For those who upload instead, AI reads deposit frequency and actual earnings, which extends coverage to gig workers and guarantors.

The second layer is identity. A government-issued ID is photographed front and back, a live selfie is captured, and facial recognition confirms the two match — addressing the gap between the name on paper and the person who shows up. The third layer examines uploaded documents at the data level, checking file structure, metadata, and generator fingerprints for tampering that looks clean to the eye.

Everything converges into a single verdict per application — one of five, each carrying a risk level and the evidence behind it. Notably, the platform grades evidence quality: a direct bank connection differs from a source-downloaded PDF, which differs from a scan or phone photo. That distinction lets an approval team move fast while a review team still knows which applications deserve a sample. ProofUp positions itself against unverified approvals, which it says default far more often.

**Pricing & Plans:** Contact for pricing. ProofUp does not publish public tiers on its site; pricing is arranged through a demo request and depends on portfolio size and screening requirements.

- **Income verification from the source:** Applicants connect bank and payroll accounts through Plaid so earnings are read from the account itself, with no document in the path to forge. Uploaded documents are also analyzed for deposit frequency and real income.
- **ID plus live selfie matching:** A government ID photographed front and back is matched against a live selfie using facial recognition, catching borrowed identities before keys are handed over.
- **Document forgery detection:** Uploaded PDFs are read at the byte level for hidden text layers, metadata mismatches, generator fingerprints, and post-generation edits — evidence that visual inspection misses.
- **Five graded verdicts with reasons:** Each application returns one of five verdicts (pass, pass with caution, non-recurring, needs review, fail) with a risk level and the specific signals that produced it.
- **Auditable decision trail:** Reports record verification method, document source, per-attempt history, and plain-language flag explanations, so decisions are defensible and reviewable.

**Strengths:** Income is verified from the account via Plaid, so there is no forgeable document in the strongest path; Combines income, identity, and document-fraud checks in a single 2-3 minute flow; Five graded verdicts with explicit reasons and risk levels beat a simple pass/fail; Evidence-quality grading separates source-downloaded PDFs from scans and photos

**Limitations:** No public pricing — you must book a demo to get numbers; Strongest results depend on applicants connecting bank and payroll accounts, which some may resist; Document-level fraud analysis only applies to applicants who upload files rather than connect accounts

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
