## Decision

**Choose Shortwave when its documented boundary matches the job.**

Shortwave fits Gmail users who want an AI-focused separate client with search-history and quota choices. The cited sources describe it as an AI-assisted email inbox option. Choose it when a separate Gmail client is acceptable. AI search history and thread limits depend on the plan.

## Setup

**Start by confirming platform and the data path.**

Confirm this setup detail before you build a routine: iOS, Android, macOS, Windows and web sign-in. Then verify the processing boundary — Data stored in Google Cloud; named subprocessors include OpenAI, Anthropic and Pinecone — and keep the first sample low-risk until the account, device, or runtime behavior matches the source description.

## Workflow

**Workflow: email AI search, summaries, autocomplete and AI-powered filters.**

Use Shortwave for email AI search, summaries, autocomplete and AI-powered filters. Customization is described as the product’s available search, drafting, and account controls. Keep the workflow small enough to review its output and control settings; the cited sources do not establish a universal quality or speed result.

## Alternatives

**Compare Shortwave by the constraint that decides the work.**

- 2023 independent review is historical workflow evidence, not current plan evidence.
