## OpenParser AI

OpenParser AI is built for teams whose work depends on being able to prove where an answer came from. You point it at the material you already have — uploaded files such as PDF, DOCX, XLSX, PPTX, and CSV, or live connections to Google Drive, SharePoint, a SQL database, or any website URL — and it indexes and reasons across all of those sources at once. Ask a question in plain English and you get an answer with references you can open and check, rather than a plausible-sounding summary.

Beyond simple question answering, OpenParser ships pre-built Agents that complete entire work products instead of leaving you with a chat log. Examples include contract and legal review that extracts clauses, risks, and obligations across a whole contract set; compliance and privacy gap checks for frameworks like GDPR, HIPAA, SOC 2, and ISO 27001; and data quality agents that validate invoices against purchase orders and flag duplicates. Agents can be used as-is or customized.

The platform is designed around verifiability and control. It is permission-aware with role-based access, SSO, and full audit logs, and it can run on the vendor's hosted SaaS or be deployed on your own servers or private cloud. Rather than locking you to one provider, it lets you bring your own LLM — OpenAI, Anthropic, Gemini, Mistral, Llama — with Llama as the default. OpenParser AI is a product of Innovatix Technology Partners, a firm that has delivered enterprise document and communications systems for insurance, financial services, and healthcare since 2003.

**Pricing & Plans:** A 15-day free trial of the full product is available with no credit card and no auto-billing. Beyond that, OpenParser offers hosted SaaS plus on-premises and private-cloud deployment, with pricing handled through a sales conversation; the site also lists a contact-for-pricing model for enterprise options.

- **Cited answers, not model memory:** Every response carries a citation back to the page, row, or paragraph in your own sources, and the platform says so when a claim cannot be supported.
- **Agents that finish the job:** Pre-built agents produce complete work products such as risk registers, compliance gap reports, and validated invoice batches instead of a raw chat log.
- **Multi-source connectivity:** Reads uploaded documents plus live website URLs, and connects to Google Drive, SharePoint, and SQL databases with auto-sync to keep content current.
- **Plain-English SQL and document Q&A:** Query SQL databases and search document sets in natural language without needing SQL skills or manual reading.
- **Permission-aware and deployable anywhere:** Role-based access, SSO, and full audit logs, with hosted SaaS or on-premises/private-cloud deployment and a choice of underlying LLM including your own endpoint.

**Strengths:** Answers come with citations back to your sources, supporting verification and audit; Pre-built agents return finished work products rather than just a chat transcript; Deployment flexibility: hosted SaaS, on-premises, or private cloud; Bring your own LLM, with Llama as the default engine

**Limitations:** Enterprise-oriented, so pricing requires contacting sales rather than self-serve checkout; Value depends on connecting your own document and database sources first; Some advanced work-product agents are aimed at specific regulated verticals

## StealthWriter

StealthWriter is built around two steps: scan and rewrite. The detector highlights sentences that still read as AI-written, and the humanizer then rewrites the text to smooth those passages out. Because you can run the detector again afterwards, it works as an iterative loop rather than a one-shot button, which makes it more practical for longer articles where only a few paragraphs sound robotic.

The tool targets people who draft with large language models but publish under their own name: bloggers, marketers, copywriters and researchers. Output can be tuned by rewriting level and, at the sentence level, by picking from alternative phrasings. Processing is quick — typically a matter of seconds — and the free tier with 10 daily humanizations and 1,000 words per input is enough to test whether the tone matches your writing style. Paid plans raise both the daily allowance and the maximum input length, which matters if you humanize long-form content regularly.

StealthWriter is a service of AiVantage LLC. On privacy, the company states that text submitted for humanizing or scanning is not stored after processing, not shared with third parties and not used for training. It is best treated as a drafting and polishing assistant: it improves how naturally AI-assisted text reads, but you should still review facts, claims and citations yourself before publishing.

**Pricing & Plans:** Freemium. The free plan costs $0 and includes 10 humanizations and 10 AI scans per day with up to 1,000 words per input. Paid tiers are Starter at $20/month (50/day), Plus at $50/month (150/day), Pro at $100/month (350/day) and Scale at $400/month (2,000/day), each allowing 5,000 words per input, with discounts for annual billing.

- **AI text humanizer:** Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
- **Built-in AI detector:** Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
- **Alternative rewrites per sentence:** Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
- **Fast batch processing:** Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
- **Volume-friendly quotas:** Daily allowances scale with your plan, from 10 humanizations a day on the free tier up to 2,000 a day on the Scale plan, for high-volume content workflows.

**Strengths:** Free plan lets you test the humanizer and detector at no cost; Detector and humanizer in one workflow makes quality checking easy; Sentence-level alternative rewrites give fine control over tone; Three rewrite strengths suit different content types

**Limitations:** Monthly quotas are metered per day, so bursty heavy users may hit limits; Humanised text still needs a human read-through for factual accuracy; Result quality varies by language and by how obviously AI-written the source is; No built-in grammar or plagiarism checker beyond the AI detector
