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 Readwise?

Readwise launches Books, its own ebook store and reading app, a week after unbundling.

Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.

Dropbox Sign vs Readwise: editorial side-by-side

D2.5

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.

6.3

Readwise launches Books, its own ebook store and reading app, a week after unbundling.

◆ Current state

Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.

◆ Where it's heading

Readwise is moving from a layer on top of other people's reading apps to owning the purchase and the reading itself. The unbundle, the free Books app and the shared MCP server point to separate entry products that all feed the same account. Reader keeps its weekly cadence of TTS, transcript and parsing work underneath.

◆ Prediction

Expect weekly Books fixes and Kindle-import work, and a move from invite-only to open signup if the store holds up.
