## Chart

Chart is built for the fintech companies and financial institutions that need authoritative proof of a customer's income without waiting on manual document review. Instead of asking applicants to upload PDFs and trusting what they send, Chart connects to the ultimate source of truth — the IRS and leading tax preparation software — so verified records can be retrieved in seconds. Because the data arrives already parsed into well-formed JSON through automatic OCR, it slots directly into underwriting, onboarding and risk workflows rather than needing a second data-entry step.

The platform gives developers three submission paths: clients can connect their IRS Online Accounts, link their tax-preparation software, or complete official IRS forms. From there a consent flow lets each taxpayer choose which documents to share, and Chart never persists user credentials — every session requires re-authentication. The company reports SOC 2 Type II compliance with reports available on request, and offers granular access controls plus optional PII anonymization and obfuscation for teams with strict privacy requirements.

Chart positions itself as an integration layer rather than an end-user app: a developer-centric REST API with SDKs, sandbox environments and documentation is the main surface, and the company emphasizes high-touch support alongside real-time performance. Pricing is quoted per enterprise engagement, so interested teams typically start with a demo rather than self-serve signup.

**Pricing & Plans:** Pricing is not published publicly; the site directs teams to book a demo and route to API docs for integration details. Commercial terms are handled per engagement (contact for pricing).

- **Direct IRS and tax-software connection:** Retrieves verified tax transcripts straight from the IRS and leading tax preparation platforms, returning records within seconds.
- **Structured JSON output:** Automatic OCR parses tax documents into well-formed, organized JSON that developers can wire into their own systems.
- **Developer-centric REST API:** Ships with SDKs, sandbox environments and detailed documentation so teams can integrate quickly.
- **Flexible client submission paths:** Applicants can connect an IRS Online Account, link tax-preparation software, or fill out official IRS forms.
- **Enterprise-grade privacy controls:** SOC 2 Type II posture, non-persistent credentials, granular consent, and optional PII anonymization or obfuscation.

**Strengths:** Pulls data from the authoritative source (IRS plus tax-prep software) rather than self-reported documents; Clean structured JSON with automatic OCR removes manual parsing work; Strong security posture with SOC 2 Type II, non-persistent credentials and granular consent; Developer-friendly with REST API, SDKs and sandbox environments

**Limitations:** No public self-serve pricing, so adoption starts with a sales conversation; Aimed at fintech and institutional clients, not individual consumers; Requires integration effort compared with a simple off-the-shelf form tool

## PDF.ai

PDF.ai is an AI document assistant that turns static PDFs into something you can talk to. You upload a file, then ask questions in natural language and receive answers grounded in the document, with citations pointing back to the relevant passages so you can check the source. This makes it practical for long reports, research papers, contracts, manuals and any dense document where you need a specific fact rather than a full read-through.

Beyond Q&A, the platform handles common document chores. It can summarize long documents, extract specific fields or structured data, and help you locate details quickly across multiple files. Because answers include citations, it suits readers who need to verify what the AI says rather than trust it blindly.

For teams that build their own tools, PDF.ai also ships a developer API. The API can parse documents, extract structured data and split PDFs, letting you embed document understanding directly into your own applications and pipelines. The combination of a polished chat interface for end users and an API for developers makes PDF.ai useful both as a standalone reading assistant and as a building block for document-heavy products.

**Pricing & Plans:** PDF.ai uses a freemium model with a free trial. Free access is limited in how many documents and questions you can use each day, while paid subscriptions raise those limits and unlock heavier usage plus API access. Check the official pricing page for current tiers and rates.

- **Chat with PDFs, with citations:** Ask questions in plain language and get answers drawn from your document, with citations back to the source passages.
- **Summaries and instant answers:** Generate quick summaries and find specific answers in long reports, contracts and papers without reading every page.
- **Data extraction:** Pull structured data and fields out of documents to reuse in spreadsheets, apps or other automations.
- **Developer API for parsing and splitting:** Use the API to parse documents, extract data and split PDFs programmatically inside your own workflows.
- **Multi-question document workflow:** Ask follow-up questions to dig deeper into a document, or jump between multiple uploaded PDFs in one workspace.

**Strengths:** Chat with PDFs and get answers with source citations; Handles summarization, Q&A and data extraction in one tool; Developer API for parsing, extracting and splitting documents; Free tier and trial make it easy to evaluate

**Limitations:** Free usage is limited in the number of documents and questions per day; Heavier workflows and API usage require a paid subscription; Answer quality still depends on the clarity and formatting of the source PDF; Scanned or image-only PDFs may need good OCR to be understood accurately
