About

Promptron

Features
Read full description

Promptron is an on-device prompt workspace for turning rough intent into a structured request aligned to the Claude or Codex/ChatGPT product surface you choose. It combines bundled capability guidance, local organization, and reviewable evaluation signals. It does not promise objectively β€œbetter” prompts or guarantee AI output. WRITE FOR THE TARGET YOU CHOOSE β€’ Choose a Claude or Codex/ChatGPT target independently from the provider that writes the prompt. β€’ Use bundled, target-specific capability guidance. β€’ Review structured sections, compatibility checks, and transparent static or model-assisted evaluation signals. BRING YOUR OWN KEY β€’ Add an Anthropic or OpenAI API key in Settings. β€’ Requests go directly from your device to the matching provider. Promptron has no model-request proxy. β€’ If both providers are configured, an allowed fallback provider can still prepare the selected target prompt without changing its target guidance. β€’ Provider usage is billed separately under your Anthropic or OpenAI account. PRIVATE BY DESIGN β€’ Projects, conversations, generated prompts, scores, and local profiles stay on your device. β€’ Provider keys are stored separately in Keychain. β€’ Promptron contains no advertising, Promptron analytics, or cross-app tracking. β€’ Before a provider first receives content for the current local profile, Promptron explains what may be sent and asks for permission. Anthropic and OpenAI permissions are separate and revocable. WORK YOUR WAY β€’ Organize conversations in an on-device workspace. β€’ Add selected files, images, or web references when relevant. β€’ Use on-device dictation where the language and device support it. β€’ Copy results. Pro adds additional prompt forms, full bundled retrieval, multi-project organization, live evaluation, and HTML export. PROMPTRON PRO Promptron Pro Monthly is a one-month, auto-renewable subscription that unlocks app features. It does not include Anthropic or OpenAI usage. The localized price is shown before purchase. Payment is charged to your Apple Account at confirmation. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel through your Apple Account. Restore Purchases is available in the Pro screen. AI output and evaluation signals may be inaccurate and are not professional advice. Verify results before relying on them.
