Dropbox Sign vs Double: at a glance
What is Dropbox Sign?
Dropbox Sign's API can now check a PDF's fields before a signature request goes out
Dropbox Sign's changelog is mostly API work and documentation. The October release adds POST /v3/document/detect_fields, which analyses a PDF for form annotations or Text Tags and returns reusable field definitions with warnings and errors before anything is sent. Expiration dates now work on template-based, embedded and bulk sends, and can be added to an existing request. Earlier changes raised the per-request file limit to 100 and began a gradual rollout of a redesigned mobile signing page.
What is Double?
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.

Dropbox Sign's API can now check a PDF's fields before a signature request goes out
◆ Current state
Dropbox Sign's changelog is mostly API work and documentation. The October release adds POST /v3/document/detect_fields, which analyses a PDF for form annotations or Text Tags and returns reusable field definitions with warnings and errors before anything is sent. Expiration dates now work on template-based, embedded and bulk sends, and can be added to an existing request. Earlier changes raised the per-request file limit to 100 and began a gradual rollout of a redesigned mobile signing page.
◆ Where it's heading
The visible work targets developers who generate signature requests programmatically: fewer failed sends, and the same options across every send path. It is steady API maintenance rather than new product territory.
◆ Prediction
More endpoint parity work is the likely next entry, given that expiration support was just extended to the remaining send endpoints.
Double

Double turns a recorded Chrome session into an agent that repeats the task.
◆ Current state
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
◆ Where it's heading
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
◆ Prediction
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
