Generate personalized Upwork proposals using your own Anthropic API key. Store Description Upwork Proposal AI – Secure, BYOK Proposal Generator Stop wasting hours writing generic proposals that get ignored. Upwork Proposal AI reads the exact Upwork job you are viewing and uses Anthropic's flagship Claude 3.5 Sonnet model to generate a highly personalized, targeted proposal in seconds. How it works: Purchase a license key from Your Service Swiftly. Enter your license key in the extension popup. Provide your own Anthropic API key (BYOK architecture ensures total privacy and the absolute lowest operating cost). Go to any Upwork job posting and click "Generate Proposal." IMPORTANT SETUP INSTRUCTIONS (Bring Your Own Key): To use this extension, you must have an active Anthropic API key. Create a free account at console.anthropic.com. To prevent spam, Anthropic requires you to verify a phone number to claim your free $5 API credit, or deposit a minimum of $5 to unlock API access. Generate your API key and paste it into the extension's Options page. Your data is completely secure. We do not store, track, or read your API keys or generated proposals. All communication happens directly between your browser and Anthropic.
