BYOK API Cost Estimation
Short answer
use.fo BYOK costs: the one-time license ($29.99 desktop or $9.99 mobile) plus your API provider's usage fees. For Groq (currently one of the most affordable providers), STT and rewrite costs for typical use are often under $5/month for moderate users. Exact costs depend on your usage volume and the provider pricing at the time.

Steps
- Understand the cost components
use.fo BYOK has two cost components: (1) The use.fo BYOK license — a one-time fee of $29.99 for desktop or $9.99 for mobile. (2) Provider API usage fees — these are charged by your provider (Groq, OpenRouter, etc.) based on your actual usage.
- Estimate your voice minutes per month
Use a simple, repeatable input: minutes dictated per workday × workdays per month. Example A: 5 minutes × 20 days = 100 minutes/month. Example B: 30 minutes × 20 days = 600 minutes/month.
- Estimate STT costs with Groq
Groq offers Whisper-based STT at rates published on their pricing page. As of mid-2026, Groq's speech-to-text is among the most cost-effective available. At 100 minutes/month, monthly STT costs at current Groq rates are typically under $1–2.
- Estimate rewrite costs
Each dictation produces a few hundred tokens of input and output for the rewrite model. At typical use.fo usage (5–30 dictations/day), rewrite token costs with a fast, cheap model on Groq or OpenRouter are typically under $1–3/month.
- Compare to Subscription
use.fo Subscription is $7.99/mo or $69.99/yr. If your estimated monthly provider cost plus the amortised one-time BYOK license fee is less than $7.99/mo, BYOK is likely cheaper for you. Calculate your break-even point: $29.99 ÷ ($7.99 − your monthly provider cost).

Troubleshooting
Problem: My provider costs are higher than expected
Solution: Check which model is selected for rewrite in use.fo BYOK settings. Some models are significantly more expensive per token. Choose a smaller, faster model for everyday rewriting and reserve larger models for complex tasks.
