💡 Pro Tip: Best Value for Money
For the optimal balance of quality and cost, we recommend using Gemini 3 Flash for translation and Gemma 4 for OCR. Since OCR is the primary cost driver (5-6x more expensive than translation), switching to Gemma for screen scanning reduces your total hourly cost by approximately 3 times.
• Translation: Gemini 3 Flash
• OCR: Gemma 4 (DeepInfra)
• Estimated cost: ~$0.29 / hour
• Translation: Gemma 4
• OCR: Gemma 4 (DeepInfra)
• Estimated cost: ~$0.18 / hour
Disclaimer: Costs are estimates based on a 750ms Scan Interval and are provided for illustrative purposes only. Actual costs depend on screen content, token density, and current API pricing.
