A W3C browser API providing a transactional, NoSQL-style object database for persisting structured data client-side.
WorldScript Studio's writing app stays fully usable with no API key, model or network because every AI feature reaches providers through one service. That leaves one module for a test suite to check when a provider goes down.
Reality
WorldScript Studio says its passphrase encryption covers PWA data in IndexedDB but not its Tauri desktop app's filesystem project store. The same React/Vite code runs in both, so the storage path decides what a user's encryption setting actually protects.
Reality
WorldScript Studio's autosave checks the file on disk before writing and refuses to save over five kinds of unexpected state. Destructive recovery is limited to three actions, each tied to one failure kind and one storage backend.
Reality
A one-line change to the open call leaves a real database file in the browser, with a write-ahead log and checkpoints that survive a restart. Getting it to persist depends on which DuckDB-Wasm build you installed.
Reality
A dev.to walkthrough pairs TanStack Query with Dexie and shows why a restart cannot resume a paused write unless the mutation function was registered again before replay, plus what the outbox row has to store.
Reality
FreeToolHub runs 21 AI tools with no inference server. The mechanism is device accounting: one registry row per model recording backend, dtype, download size, and the memory floor below which it will not run.
Reality
The browser has shipped an origin-scoped mutex since March 2022. The lock lives exactly as long as your callback's promise, so the token rotation runs once no matter how many tabs notice the expiry.

A WebLLM tutorial splits cheap entity extraction from expensive reasoning with no PHI on the wire. The architecture holds up; the first-load bill and the hardware gate are the parts to cost out.
