A side-by-side editorial comparison of Readwise and Zoho Sign — release velocity, themes, recent moves, and the top alternatives to consider.
Two big swings in July and August, and since then Readwise has been paying the bill.
Readwise shipped a full mobile rewrite in late July and library-wide Ghostreader a fortnight later, and the weekly changelogs since have been almost entirely repair. The August 28 week is typical: thirteen fixes against five real improvements, spread across EPUB handling, chart and video embeds, Ghostreader chat on both mobile platforms, and Boox e-ink devices. The one consistent addition each week is parsing coverage for more publishers.
Zoho Sign is clearing the exit path off Docusign while stacking up regional legal assurance
Zoho Sign publishes through the Zoho blog, so entries are announcement posts truncated to roughly 350 characters. The recent run splits three ways: legal assurance by jurisdiction — qualified electronic signatures for the EU through SIGN8, pan-India e-Stamping — client surfaces including a native Windows app, and agent access through Zoho MCP, where a prompt can send a document for signature and track it. The newest entry adds template migration from Docusign.

The fix list is a map of where the rewrite is still settling — pagination and layout stability on Android tablets, chat sheets and message sending on mobile, exports arriving with page CSS attached. Underneath that, small capabilities keep arriving quietly: Apple Books folder-EPUBs now upload, interactive charts render as linked images instead of an import notice, non-Latin titles survive the trip to Kindle. The company is broadening what it can ingest and export while stabilising what it rebuilt.
Expect the weekly cadence to hold with fixes still outnumbering additions, and the remaining Boox and Android tablet issues to keep appearing until the mobile rewrite fully settles.

Two motions, both aimed at displacement. Zoho is assembling the assurance levels that let it be used for agreements a standard e-signature cannot carry, jurisdiction by jurisdiction, which is what removes the reason enterprises stay with an incumbent. And it is removing the switching cost directly: bringing Docusign templates across in minutes attacks the specific lock-in that keeps a customer on a platform whose documents are already built there. The MCP work runs alongside, making signature workflows something an agent initiates rather than a person.
Template migration is the first piece of a switching kit rather than the whole of it; expect the remaining Docusign artefacts — envelopes in flight, saved recipients, completed-document archives — to follow, since a template alone does not move a live signing operation.
