Ship a prototype, automate the boring middle, build the deck and understand the numbers — a founder's whole week in one list.
Flocci AI Tools lists 111 of them, ordered free tiers first: Alibaba Quark AI Assistant, Baichuan Bai Xiao Ying (百小应), Baidu Ernie Bot (Wenxin Yiyan), Falcon LLM Chat (TII) and HuggingChat. 89 of the 111 are free or have a free tier. Each entry states what it uniquely does rather than a score.
16 on this page are marked fully free with no paid plan at all: Alibaba Quark AI Assistant, Baichuan Bai Xiao Ying (百小应), Baidu Ernie Bot (Wenxin Yiyan), Falcon LLM Chat (TII) and HuggingChat. The remaining 95 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.
They are every catalog entry in 6 sub-categories that map to what startup founders actually do: build an MVP, automate ops, make an investor deck, research customers, read your own data. There is no sponsorship and no paid placement anywhere in the ordering.
