PromptSpend vs AI Usage Limits

Know the tab before you build. PromptSpend turns a representative AI conversation into an understandable cost forecast before the first production invoice arrives. Paste sample text or enter known token counts, choose your traffic, and see the cost per conversation, day, month, and year. COMPARE THE SAME WORKLOAD Select up to four LLMs and compare their estimated costs side by side. PromptSpend calculates pasted text separately for each model family, ranks the results, and shows the monthly difference from the lowest-cost option. SEE THE FULL COST STORY Explore input, output, prompt-cache writes, long-context tiers, reasoning assumptions, batch discounts, and conversation growth. The Cost Brief, sensitivity lab, and savings playbook help explain what changes the number and which levers may reduce it. CURRENT PRICES WITH EVIDENCE PromptSpend downloads a validated public catalog, shows when sources were checked, flags disagreements for review, and refuses to hide an expired offline cache behind a reassuring number. Open the evidence and public sync status whenever you want to inspect the work. OPTIONAL PRICE ALERTS Create and manage an email alert for price changes without creating an account. Your email address and alert choices are sent only when you opt in, and every alert includes a way to unsubscribe. Native push notifications are not part of this release. SHARE THE COST STORY Create a readable estimate, four-model comparison, CSV export, restorable website scenario, or Estimate Receipt. Shared results contain derived counts, assumptions, costs, and source dates—not your pasted prompt text. AUDIT AN EXISTING CONVERSATION PromptSpend Receipt provides visible instructions to send in your AI conversation. Import the assistant's structured result, review its estimates and limitations, and share an image or readable text. Imported results are processed locally and cleared when you leave the Receipt screen. LEARN AS YOU GO Short guides explain tokenization, context growth, caching, pricing provenance, and the limits of any estimate. Global Search and a guided tour make deep features easy to find. MAKE IT YOURS Choose system, light, or dark appearance; four accessible accent colors; and cool or warm canvas styles. The Market Pulse ticker can be paused and respects Reduce Motion. PRIVATE BY DESIGN Pasted text is processed on your device and is not uploaded or saved by PromptSpend. There is no native account, advertising SDK, behavioral analytics, cross-app tracking, or tracking identifier. Saved scenarios and appearance settings stay on your device. Optional alerts transmit only the email address and choices you submit for that feature. PromptSpend estimates published API charges from the workload and assumptions you provide. Separately billed cache-storage time is disclosed but excluded unless a retention duration is known. Actual bills, model quality, latency, availability, regional pricing, negotiated rates, and provider behavior can vary. Validate a representative workload before making a production decision.

See how much of your AI allowance you have used, and when it resets, without opening a single dashboard. Every provider hides your remaining quota somewhere different. AI Usage Limits puts them on one screen — and on your Home Screen and Lock Screen. SUPPORTED SERVICES • Claude — session (5-hour) and weekly windows • ChatGPT / Codex — rate-limit windows • Grok — credit usage • Cursor — plan usage • OpenRouter — credit limit and balance WIDGETS • All Providers — everything you have connected, at a glance • Single Provider — one service in full detail, with reset times • Home Screen and Lock Screen sizes, including inline and circular • Every widget shows when it last updated, and flags stale figures rather than passing them off as current TRY IT FIRST Not ready to connect an account? Turn on sample data during setup or in Settings and the app fills itself — dashboard and widgets — with made-up figures so you can see exactly what you would get. BUILT TO BE BORING ABOUT YOUR DATA • No account, no server, no analytics, no ads, no tracking • You sign in on each provider's own page in Safari — the app never sees your password • Credentials are stored in your device Keychain and sent only to the provider they belong to • The app asks for the narrowest access it can. Its Claude token can read your usage and cannot send prompts or spend your allowance • "Delete all data" removes every credential, cached figure and preference from your device • About → Privacy & connections lists exactly what each service is asked for FREE AND OPEN SOURCE No ads, no subscription, no paid tier. The whole app is on GitHub — read exactly what it does and what it sends. PLEASE NOTE This is an independent app and is not affiliated with, endorsed by, or sponsored by Anthropic, OpenAI, xAI, Anysphere or OpenRouter. Except for OpenRouter, it reads usage endpoints those companies have not documented, so a service can change and temporarily stop reporting. Figures are indicative — your provider's own dashboard is authoritative, and you should not rely on this app for billing decisions.
