Tokensaver
Track per-service AI token usage. Don't get capped.
Once a month you read the token count off each AI service's billing page and log it here. Tokensaver flags anything past 90% of cap — before the cap — and shows across months which services drain it. Free, no keys, no account.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.

What you can do in Tokensaver on the web
Cap meter per service
Every logged month shows tokens used against the cap with a filled meter, a marker at your warning threshold, and a Room left / Watch it / At the cap / Over cap read.
Flagged before you get capped
The home screen banners any service past your threshold (90% by default, adjustable) with the exact headroom left in tokens.
18 AI services with their usage pages
OpenAI, Anthropic, Gemini, OpenRouter, xAI, DeepSeek, Mistral, Groq, Together, Fireworks, Cohere, Perplexity, Azure OpenAI, Bedrock, Replicate, Hugging Face, ElevenLabs and Cursor — each with the page to open and where to look on it. Add your own too.
Every month reads as a trend
Each service-month shows how it moved against the same service last month — +230k vs Aug — so a creeping service is obvious before it caps.
Months of trail, charted
Tokens per month, share of the month by service, cap pressure all-time, and a month-over-month line per service.
Manual on purpose
Tokensaver never calls an API and never holds a key — it links out to the billing page and you type the number in. Everything stays in this browser.

Questions
Is the web version of Tokensaver free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Tokensaver iPhone app?+
Entry is manual by design: the web version cannot read your provider's usage API any more than the iPhone app can, so you copy the number off the billing page. No push notification when a service crosses the threshold — the flag shows the next time you open the app. Your ledger lives in this browser only; export the JSON backup or the CSV to move it.
