Most "free" screeners mean free after you hand over an email. This one runs before you have typed anything.
There is a specific frustration in evaluating trading tools: every one of them wants an account before it will show you whether it is any good. You sign up, confirm an email, and only then discover the free tier does not cover your timeframe.
altscreenerai runs the other way round. Open it and the scan works. No account, no email, no card, no trial clock.
One thing separates free from paid, and it is deliberately a single clean line rather than a scattering of small restrictions: candle size.
| Candle size | Access |
|---|---|
| 1d, 8h, 4h | Free, no account |
| 1h, 30m, 15m, 5m, 3m | Paid, from $15/mo |
The reasoning is straightforward. Faster candles mean scanning the full universe far more often, which is the part that actually costs money to run. It also happens to line up with who needs what: if you hold positions for days, the free timeframes cover you completely. If you trade intraday, the faster candles are the product.

A signup wall in front of an unevaluated product is a bet that people will pay the friction to find out. Most do not — they leave and use whatever loaded instantly. Putting the working product first is simply a better trade for both sides: you find out in thirty seconds whether it is useful, and we do not collect email addresses from people who were never going to stay.
