Why Pro?
Stop re-entering the same numbers.
Every cost estimate you run disappears when you close the tab. Pro saves each calculation so you can pull up last week's Claude Sonnet batch quote in two seconds — no spreadsheet archaeology required.
Your models, your prices.
If you run fine-tuned or private models with negotiated rates, the public price list is useless. Pro lets you enter any input/output cost per million tokens and saves those custom presets alongside your calculations — so your cost modeling reflects reality.
Built for teams billing by project.
Consultants and agencies can tag saves by client or project, then export the full history to CSV at invoice time. One export replaces an hour of digging through API dashboards and spreadsheets.
Pricing FAQ
Is there a free trial for Pro?
Pro does not require a credit card to evaluate — the Free plan gives you full access to every calculator and tool. When you are ready to save and organize calculations, upgrade to Pro at any time.
Can I cancel anytime?
Yes. Cancel from your billing portal with one click. Your Pro access continues until the end of the billing period you already paid for. No questions, no friction.
Where is my data stored?
Saved calculations are stored in Cloudflare KV (edge storage). Payment information is handled exclusively by Polar.sh and is never stored on our servers. All cost calculations continue to run locally in your browser.
Do you offer team or enterprise plans?
Not yet. Team plans are on the roadmap. If you need multi-seat access now, email us at contact@toksum.dev and we will work something out.
What is your refund policy?
If you are unhappy within 14 days of your first charge, email contact@toksum.dev and we will issue a full refund — no questions asked. After 14 days, refunds are handled case by case.
