About & criteria
Data source
The directory comes from a local dataset built from the public aibase directory (aibase-dataset); 5931 entries after filtering. We do not scrape or mirror paid content, only public descriptions and official links.
How "free" is decided
- Positive signals: free use, free tier, free version, free credits, free trial, free plan, no signup, no registration, freemium;
- Negative signals: paid only, requires payment, no free version — these subtract from the score;
- One entry per domain: the strongest free signal, then the highest traffic;
- This is a text-signal filter, not a pricing promise — limits and trials are always per the official site.
What we do not do
- We do not issue or redeem codes or invites;
- We do not offer ways around paywalls, shared accounts, or cracking;
- We do not list "free claims" that ask for payment, transfers, or your credentials.
Listing and removal
Listing criteria: the official page clearly offers a free tier or free credits. If a tool drops its free tier or the verdict is wrong, we adjust based on the official information.
