Stop trusting one model with hard questions.
Assembly runs your question past agents from 3 or more model families. You keep one sourced answer in 3 to 15 minutes.
No account. Keys stay in your browser. First progress in seconds.

Getting keys sounds like work. Is it?
Ten minutes, once. Grab free keys from two providers, paste them in, done. No card, no account.
Why not just ask one good model?
One model gives one confident guess. Assembly makes agents from different families argue first, so weak claims die before you read them.
Do my keys or questions leave my machine?
Keys stay in your browser. Questions go to the model providers you chose, nothing is stored on our server. Note: some free tiers (for example Gemini) may reuse inputs for training.
Can I trust the final answer?
Trust it the way you trust a cited draft. Every answer lists numbered sources, a confidence level, and what stayed uncertain.
