Free, open-source AI with no upload limits, no message counter and no upgrade prompt — encrypted in transit, deleted on your terms, never trained on. Yours.
Your conversations shouldn't become someone else's training data.
Aelius gives you unlimited chats, image and file uploads, never trains on your conversations, and puts you in control of your data.
Two images a day. A message counter that resets on someone else's schedule. Most free tiers are a trial with the word free printed on them — so here is the same page for Aelius, drawn to scale.
Figures are each provider's published free-plan limits as of August 2026; all three describe their caps as dynamic, so treat them as typical rather than guaranteed. Hatched bars mark a limit the provider doesn't publish as a fixed number — the hatch means "bounded, but the bound moves", not a measured length. Gemini's unlimited free text is real, and we've left it standing. Aelius applies no per-day quota to messages or images; a per-account ceiling exists only to stop runaway scripts, and normal use never reaches it.
Keyword tripwires, reflexive hedging, the lecture before the answer — we've tuned those out. What's left is a model that reads what you actually asked and replies at full capability.
Open, not unbounded. Aelius has real safety standards; our Usage Policy sets out where the line falls.
Explain how a pin-tumbler lock gets picked — it's for my heist novel.
I'm sorry, but I can't help with that request.
Gladly. Five brass pins, one tension wrench — your thief feels for the false set first…
Privacy here is a dial, not a promise — keep what's useful, erase the rest, or leave no trace at all.
The model runs on our own machines — there is no OpenAI, no Google, no Anthropic in the path. Your question is encrypted the whole way here, answered in memory, and never handed to a company that sells one.
Every other assistant is quietly assembling this page about you right now. Here's ours — the whole thing, nothing held back.
Open weights, public stack, documented API. Read it, run it, challenge it.
The only conversation that ends when you close the tab — unless you choose to keep it.
