Pricing methodology

AISub collects ChatGPT website subscription quotes and App Store in-app purchase prices for ChatGPT, Claude, Gemini, Perplexity and Grok. The channels are compared separately; missing prices are never filled from another channel. Google Play subscriptions are not currently covered.

Confirm available plans, billing periods and final amounts at checkout through the selected channel. Purchase conditions may vary by billing location, account eligibility and payment method.

The following tax rules apply to website quotes. See the separate App Store section below for in-app purchase prices.

The table uses the same tax treatment for local and converted prices. It uses the tax-inclusive amount by default. If a lower price before tax is also available, that amount appears in teal and the tax-inclusive amount is crossed out. If only a price before tax is available, that is the amount shown. Quotes with unspecified tax treatment keep their original amount and are labeled accordingly.

The label “Tax-free price” refers to a price before tax. Any tax due is determined at checkout. Crossed-out amounts provide a comparison with the tax-inclusive price; they do not establish a promotional discount. Missing prices and tax details are marked “Not provided” and are not calculated from tax rates.

Price rankings, minimums, ranges and annual estimates use the selected reference amount. Tax filters match the tax treatment of that amount.

Exchange rates are obtained daily from ExchangeRate-API and express the value of one US dollar in each currency. To convert a quote, AISub divides the original amount by the rate for its currency, then multiplies by the rate for the selected display currency.

All regions are compared using the same set of rates. Rankings use amounts before rounding. Converted prices are estimates; card issuers may apply different rates and additional fees.

Business and Business 5x prices are per seat. Monthly billing shows the amount charged each month. Annual billing shows the monthly equivalent of a yearly payment; the estimated yearly amount is that monthly price × 12. The same calculation applies to other plans with a confirmed monthly equivalent for annual billing.

If an annual quote has not been confirmed as a monthly equivalent or a yearly total, AISub retains the original amount and marks it as unverified. It is excluded from monthly conversions and price rankings. Missing annual prices are not estimated from monthly plans. Minimum seat requirements are confirmed at checkout.

App Store prices are collected from each storefront and compared separately from website prices. Distinct tiers and storage capacities remain separate: similar names or equal prices do not establish equivalent benefits.

Explicit purchase labels such as Monthly or Annual take priority, followed by valid manual assignments. Other prices follow the global policy: source labels only, same-item paired-price inference at a 6 to 14 ratio, or paired inference plus a monthly default for a single amount. Inference and defaults are marked estimated; remaining prices keep an unknown period. Annual amounts are divided by 12 for monthly comparisons, and those conversions also depend on the estimated period. Confirm actual billing periods and charges in the app.

For Claude, Gemini, Perplexity and Grok, prices whose periods cannot reasonably be inferred retain each distinct amount with an unconfirmed period. They are excluded from monthly conversion, yearly totals and price alerts. Usage balances denominated in USD are shown separately, not compared as a fixed number of credits. Business plans are shown only in the website channel.

Whether sales tax is added depends on the applicable billing location and the tax rules for the item. Refer to your Apple transaction receipt for the actual tax amount. When the page does not establish the tax treatment, we mark it as unknown and do not classify the price as tax-inclusive or tax-exclusive.

The website provides a price per credit. The reference multiplies this rate by 100 and converts currencies. It does not establish a fixed 100-credit pack or the ability to buy a single credit.

App Store prices cover the complete pack listed by the source. The reference divides the pack price by its credit quantity, multiplies by 100, and converts currencies.

Tax, expiry and supported features remain unknown unless explicitly stated by the source. Prices are for reference; confirm the offer and final total at checkout.

The latest response did not provide credits. The previous quote is retained.

Daily updates are scheduled for 08:00 Beijing time (UTC+8), with an additional retry scheduled for 09:00. Eligible unfinished regions also resume automatically, so retries can occur outside the 09:00 schedule. Queueing, source cooldowns and request limits affect actual execution times.

Prices and exchange rates have separate update times. The rate source publishes once a day, and AISub retrieves the latest set during the daily update, so the exchange rate time can be from the previous day. Prices and exchange rates older than 48 hours are flagged. If a regional update fails, the last successfully retrieved price remains available.

UTF-8 CSV of currently valid subscription quotes for ChatGPT, Claude, Gemini, Grok, Perplexity (website and App Store), covering registered public plans. Billing periods follow explicit source labels, manual assignments or the active global inference rules; inferred periods remain estimates. Usage balances and offers with an unknown period are excluded.

Collection is scheduled daily at 08:00 Beijing time (UTC+8), with an additional retry at 09:00. Eligible unfinished regions also resume automatically, subject to queueing, source cooldowns and request limits. Successful updates depend on source availability. Downloads normally allow 10 minutes of browser caching and one hour of shared caching, with up to one day of background revalidation. These windows shorten when a quote approaches 48 hours old.

The export excludes invalid quotes and quotes older than 48 hours. Price pages may still display older successful quotes with a warning. If a required source is unavailable or there are no current valid quotes, the download returns an error. Check quote_updated_at in each row; coverage can vary by region, plan and billing period.

The original address, /data/prices.csv, continues to provide ChatGPT Plus monthly website quotes. It keeps the original 13 columns and format, does not apply the 48-hour filter and does not depend on other products' sources.
