The record

Product: Fillable turns PDFs into guided client flows with automatically detected fields, document uploads, e-signatures, and shareable completion links.
PDF tools: The product includes browser-based tools to fill, create, sign, merge, split, compress, convert, and OCR PDFs.
Form collection: Guided packs let teams collect completed forms and requested documents from clients, with one active pack included in the free plan.
Templates: The free plan includes all form templates and official forms in the library.
API: The developer API has REST endpoints to parse PDF fields and text into JSON and fill existing PDF form fields.
API limits: Each API key gets 100 requests per calendar day, and API calls count whether they succeed or return an error after authentication.
API limitation: The API does not create PDFs from HTML, convert file formats, or add fields to flat PDFs.
Privacy: The core PDF tools run in the browser, while server-side conversions upload files for conversion and delete them afterward.
API security: The API says PDFs are processed in memory and not stored, document content is not logged, and traffic uses HTTPS.
Client access: Clients can complete a shared form link without creating an account or installing an app.
Supported workflows: The site identifies law firms, accounting firms, immigration consultants, mortgage brokers, healthcare clinics, and real estate as intended audiences.
Billing: Paid plans are monthly, priced in USD, renew automatically, and can be canceled through the Stripe billing portal.
Support: The site lists [email protected] as its contact email.
Price from: $9/mo
