In Sidekick 26.0, Indexes give you a persistent work queue for reverse engineering! Create one from a BNQL query, then keep adding as you find more. Sidekick can also write to indexes during analysis. Later, use the index to filter down, pin what matters, and jump straight to each location. https://docs.sidekick.binary.ninja/guide/indexes.html

The Notebook in Sidekick 26.0 is where you turn chat work into something that sticks. It is a persistent workspace where you track analysis goals and record outcomes. Sidekick reads it as context in Chat, so it can build on what you already established across turns and sessions. https://docs.sidekick.binary.ninja/guide/notebook.html

In Sidekick 26.0, Chat is where most binary analysis starts. Ask a question and Sidekick uses its tools to query the binary, then the thread builds as you dig deeper. The sidebar keeps it transparent. You get a thread list with live status, changes, findings, and any approvals waiting. Open a thread to see the full conversation plus grouped tool calls so you can audit what ran. https://docs.sidekick.binary.ninja/guide/chat.html

Semantic indexing in Sidekick 26.0 lets you search by what code does instead of what it is named. It builds a local vector index for your binary. Then concept() in BNQL or the Python API can surface matches for things like TLS handshake even when everything is still default named. The index stays local, no binary content goes to the cloud. https://docs.sidekick.binary.ninja/guide/semantic_indexing.html

Working in a messy function? Sidekick 26.0 suggestion operations can repair and annotate the code right at your cursor. Start with Suggest Repairs when the analysis substrate looks off. Then use Suggest Types, Suggest Names, or Suggest Comments to apply focused improvements. Each run writes directly to the Binary Ninja database and lands as a single undoable transaction you can audit in the Transaction Log. https://docs.sidekick.binary.ninja/guide/suggestions.html

To help us track down bugs faster, 5.3 introduces opt-in crash reporting. This feature is disabled by default in paid versions and enabled by default in our free version. Either way, you can change the setting whenever you want. Details in our latest blog post: https://binary.ninja/2026/04/13/binary-ninja-5.3-jotunheim.html#crash-reporting
