Keşke in ChatGPT
Ask ChatGPT your “if only I had…” question; Keşke calculates it from TÜİK data and shows the result in a card with charts.
Use it in ChatGPT
Keşke is a ChatGPT plugin. Type one of these; the answer comes with a chart, and you can change the amount and dates in the card:
- “With Keşke: if I had put 5,000 TL a month into gold since 2020, what would it be worth today?”
- “Keşke: what would 100,000 TL put into US dollars in 2018 be worth now, after inflation?”
- “Keşke: real returns of gold, dollar, BIST 100 and deposits over the last 12 months?”
FAQ
Does Keşke give investment advice?
No. It only calculates what would have happened, from past TÜİK data; it doesn't say what to buy and makes no forecasts.
What data does it have?
Monthly returns of gold bullion, the US dollar, the euro, the BIST 100, government bonds and TL deposits, plus consumer prices, from January 1997 to September 2026 (bonds from January 2005). TÜİK publishes each month in the first days of the next; Keşke picks it up on its own.
Do I need an account or to share anything?
No. Keşke doesn't store calculations and doesn't know who you are.
What can I change in the card?
The amount, the start and end months, monthly or once, and whether the amount rises with inflation.
