What is Readwise?
Readwise is polishing the 2.0 rebuild while quietly opening the Reader API for programmatic highlights.
Readwise is in the post-2.0 polish phase: the full iOS/Android rebuild (July 24) and Global Ghostreader library search (August 7) are the two architectural moves in this cycle, and current releases are tightening edge cases around them. Reader API highlight creation, YouTube chapter navigation, and redesigned email digests extend the platform's integration and daily-use surfaces.
What is Skedda?
Skedda opens a developer API — a clear signal it's repositioning as a workplace data platform
Over the past three months Skedda has shipped across three distinct layers: booking operations (space filters, approval rule granularity, booking windows by hour), workplace analytics (occupancy insights with headcount tracking and RTO reporting, multi-venue utilization via Organization Hub), and visitor management (CSV bulk imports, reworked export formats with custom field data). The product's scope has grown well beyond room scheduling.

Readwise
5.0COLLAB
Readwise is polishing the 2.0 rebuild while quietly opening the Reader API for programmatic highlights.
◆ Current state
Readwise is in the post-2.0 polish phase: the full iOS/Android rebuild (July 24) and Global Ghostreader library search (August 7) are the two architectural moves in this cycle, and current releases are tightening edge cases around them. Reader API highlight creation, YouTube chapter navigation, and redesigned email digests extend the platform's integration and daily-use surfaces.
◆ Where it's heading
The Reader API expansion — highlights now creatable programmatically — opens Readwise to developer-built capture workflows. Combined with Global Ghostreader's library-wide AI search and the mobile 2.0 rebuild, Readwise is building toward a personal knowledge stack that external tools can write to and AI can reason across. Weekly releases are stabilizing mobile 2.0 bugs while the product team ships Reader API extensions.
◆ Prediction
Reader API update and delete endpoints will follow the new create endpoint; Global Ghostreader skills will expand with more predefined workflows and tighter Daily Review integration as the mobile 2.0 bug rate subsides.
Skedda
6.3COLLAB
Skedda opens a developer API — a clear signal it's repositioning as a workplace data platform
◆ Current state
Over the past three months Skedda has shipped across three distinct layers: booking operations (space filters, approval rule granularity, booking windows by hour), workplace analytics (occupancy insights with headcount tracking and RTO reporting, multi-venue utilization via Organization Hub), and visitor management (CSV bulk imports, reworked export formats with custom field data). The product's scope has grown well beyond room scheduling.
◆ Where it's heading
The API beta launch is the most directional move in the recent batch — it signals Skedda wants to become an integration layer in the enterprise workplace stack, not just a standalone scheduling app. With occupancy and utilization data programmatically accessible, connections to HR, facility management, and access control systems become natural. The analytics depth (headcount trends, RTO policy tracking) gives the API real data value beyond simple booking CRUD.
◆ Prediction
The next API milestone will almost certainly be write operations — booking creation and modification via API would make Skedda embeddable in enterprise onboarding and facility workflows, where bookings are triggered by other systems rather than manually entered.
