Steer Astro is free because of where its AI runs. It works inside ChatGPT, so the expensive part, the language model, runs on your own ChatGPT account. Steer only adds the Vedic and astronomy calculations, which are cheap to run. With no large AI bill to pass on, it stays free: no ads, no per-question fees.
Where the money goes in AI
In most AI products, the costly part is the model itself. Running a large language model for every question is what subscriptions and per-message fees generally pay for. The answer text is cheap; generating it at scale is not. Take that cost out of the equation, and a product can be genuinely free without ads or limits.
How Steer Astro is built
Steer Astro is an app inside ChatGPT. When you ask about your chart, ChatGPT handles the language and the reasoning on your own account. Steer's job is deliberately narrow: it runs the Swiss Ephemeris to compute your exact planetary positions, your dasha periods, the daily panchang, and today's transits, then hands those numbers back for ChatGPT to interpret. Because the heavy model already runs on your side, Steer never pays a per-question AI bill. That single fact is why it can be free, with no paywalls and no cap on how much you ask.
Free, but not lower quality
Free usually signals a downgrade. Here it does not. The reasoning comes from whatever model your ChatGPT runs, and on a paid plan that is among the most capable available today. Steer never swaps in a cheaper model to save money. Two things decide whether a reading is any good: accurate inputs and strong reasoning. Steer gives you both, exact calculations interpreted by a frontier model, and a price tag is not the third ingredient.

What it costs you, and what stays the same
You need a ChatGPT account, and the free tier works. You pay nothing extra for Steer. A paid ChatGPT plan simply means a stronger model interprets your chart. What does not change with price is the maths: every chart, dasha period, panchang, and transit is computed with the Swiss Ephemeris on NASA JPL data, the same engine professional astrologers rely on, accurate to a fraction of a degree. Your birth details stay private as well, never sold and never shared.
What you can ask it
Inside ChatGPT, Steer Astro reads your birth chart as the Rasi (D1) and Navamsa (D9) charts, tells you the Vimshottari Dasha period you are in, maps today's transits onto your chart, and gives the panchang for any date. You ask in plain language. "What does my year ahead look like?" draws on your dasha and transits; "is this a good week to begin something?" checks the panchang. The reading is conversational, and every figure behind it is computed, not guessed.
The honest limits
To be straight, there are trade-offs. Steer Astro lives inside ChatGPT, so you use it there and need a ChatGPT account. On the free ChatGPT tier the model is smaller, so a paid plan gives sharper interpretation. And it stays focused on the essentials above; for daily guidance that remembers you and looks across your whole life, that is the upcoming Steer app, a separate product on its own waitlist.
The short version: the most expensive part of an AI reading already lives in your ChatGPT account. That is why Steer Astro is free, and why being free does not cost you any quality.
