Developer platforms for model access — filter by free API quota, pricing model and data-retention terms. 10 of 77 verified tools are listed below — compare them by pricing, free plans, API access and supported platforms. We never invent prices or rankings. For the in-depth comparison, read the LLM APIs & Model Platforms guide.
Not sure which kind of tool you need? Start with our AI tools guide, then read how to use AI tools safely before connecting one to work data.
Answer four quick questions — what you want to do, who you are, your budget and must-have features — and we rank the verified directory with the reasons spelled out. Every match links to a tool profile with sources and a last-verified date. Nothing here is sponsored.
Start from the job, not the brand: pick the two or three tasks you actually need, then check the free tier's real limits — many "free" plans cap daily usage or reserve their best features for paid tiers. If you connect the tool to work data, read the privacy notes first; if you build software, confirm API access and pricing separately from the subscription. Open-source tools can be self-hosted but shift setup and updates onto you. Every profile in this directory lists what we verified, what we could not, and when we last checked — start with our AI tools guide, learn how to use AI tools safely, or browse genuinely free AI tools.
