App Store Connect, in plain English.

Agentic co-pilot for iOS developers — manage metadata, respond to reviews, and trigger releases by just describing what you want.

App Store Connect is powerful and miserable to use. Ascend sits in front of it with a Claude agent that has direct tool access to the API — developer types what they want, the agent plans the steps, calls the right APIs in sequence, and confirms. No more hunting through tabs.

WHAT WE BUILT

Tool-using agent. Full App Store access.

Anthropic Agent SDK
Multi-Step Agent Execution

Ascend is built on the Anthropic Agent SDK. The agent receives the developer's request, breaks it into a sequence of API calls, executes each tool in order, handles errors mid-chain (missing locale → generate translation), and confirms the outcome.

Tool Set
Full App Store Connect API Coverage

Fetch metadata, update localizations across all 39 App Store locales, read and respond to user reviews, check submission status, trigger a release, pull a crash analytics summary. Every operation the developer does manually — now a tool call.

Real-Time Sync
Convex Live State

Convex backend syncs App Store metadata state to the Ascend UI in real time. When the agent updates a localization or triggers a release, the dashboard reflects the change immediately — no polling, no refresh.

Review Responses
Claude Drafts. Developer Approves.

User reviews are read from the App Store Connect API. Claude drafts responses in the app's tone — the developer reviews and sends with one click. Response rate goes up, manual drafting time goes to zero.

AGENT ARCHITECTURE

How the agent executes.

PLANNING
REQUEST → STEP SEQUENCE

"Update the What's New text for v2.1 to mention dark mode and submit for review" becomes: fetch current metadata → update What's New for each locale → check submission readiness → submit. The agent plans before it acts.

ERROR HANDLING
GRACEFUL RECOVERY

If a locale is missing a required localization, the agent doesn't fail — it generates the missing translation, fills the gap, and continues. Errors surface as decisions, not crashes. The chain completes or explains clearly why it can't.

MODELS
CLAUDE SONNET

Claude Sonnet handles all reasoning, tool selection, and copy generation — including review response drafting and localization generation. The agent SDK manages the tool use loop, context window, and confirmation flow.
