Use Case Recommendations
Best for: ASSIST
ASSIST is an AI OCR and document-management platform built specifically around Southeast Asian e-invoicing compliance, which is what separates it from the generic receipt-scanning category. It captures data from invoices, receipts and other business records and turns them into structured, reportable data — but the surrounding product is shaped by two national mandates: Malaysia's LHDN MyInvois and Singapore's IRAS InvoiceNow. Submission to those systems is part of the product rather than an integration you build yourself. Three modules sit on top of the extraction engine: Smart Documents for capture and retention, Smart Claims for employee expense claims with an approval matrix, and Smart Invoice for issuing and submitting compliant e-invoices. Extracted records sync to Xero and QuickBooks, and workflow and matching logic can be customised, with custom logic and API available on the enterprise tier. Invoice retention is seven years on every paid plan, which is the statutory window these businesses are actually buying against. Pricing is metered in OCR pages rather than seats or documents, and the vendor is unusually explicit that all plans include full feature access with no hidden tiers or locked tools — the ladder buys volume. Every new account starts on a 14-day Premium trial with 30 OCR pages included and no commitment, and Singapore customers may be eligible for up to 80% PSG funding.
Ideal use cases:
- •Teams or individuals who need ai ocr extraction from invoices, receipts and business records
- •Teams or individuals who need direct submission to lhdn myinvois (malaysia) and iras invoicenow (singapore)
- •Teams or individuals who need smart claims with configurable approval matrix
- •Teams or individuals who need xero and quickbooks sync
- •Anyone focused on ocr workflows
- •Anyone focused on e-invoicing workflows
Best for: OpenParser
OpenParser is a document-parsing API whose selling point is model choice rather than a single house OCR engine. Nine hosted OCR models sit behind one request shape: PaddleOCR-VL, two generations of Mistral OCR, Azure Document Intelligence Layout and Read, Google enterprise document engines and AWS Textract among them. You change the `ocr_model` field and nothing else about your integration, which is a direct answer to the usual failure mode of document pipelines — the engine you standardised on turns out to be wrong for one document class and switching means rewriting the integration. Two endpoints carry the product. POST /parse returns a typed `openparser@1` block structure plus markdown, where blocks carry a kind (text, table, field, checkbox, signature), page number, bounding box and confidence. POST /extract fills a schema you supply and cites the block ids each value came from, so a downstream reviewer can trace any extracted field back to its position on the page. Sync, async and batch requests share the same request shape, with GET /jobs/{id} for async status and GET /files/{id}/content for reusable file bytes. Idempotency keys are supported on parse. Pricing is per page and published per model, which makes cost routing an explicit design decision: send bulk general documents to the cheapest open-weight engine and reserve the expensive enterprise engines for the layout-heavy exceptions.
Ideal use cases:
- •Teams or individuals who need nine hosted ocr engines swappable via one request field
- •Teams or individuals who need typed openparser@1 blocks with bounding boxes and confidence scores
- •Teams or individuals who need schema extraction that cites the source block id for every value
- •Teams or individuals who need sync, async and batch share one request shape
- •Anyone focused on ocr workflows
- •Anyone focused on document-parsing workflows
