Chat4o — Your Personal Strategic Advisor

A calm, trusted advisor that fits in your pocket. Whether you are drafting a proposal, untangling a difficult decision, or turning a spark of creativity into images and short films, Chat4o thinks one step ahead and replies one sentence at a time.

—— Three modes, one conversation

· Text dialogue. Long, layered thinking without losing context — perfect for writing, research, strategy and reflection. · Image creation. Turn an idea in your head into a clear visual. Posters, illustrations, concept art, social covers — start with a single line. · Video creation. Take a paragraph and let it become a short film, so your idea can be seen in motion. · Seamless switching. Move between Text, Image and Video right inside the conversation. A gentle first-run guide gets you there in five seconds.

—— A workspace built for thinkers

· Universal across devices. iPhone and iPad stay in sync, so your thinking never breaks between the couch and the desk. · Light & Dark. Follows your system, gentle on the eyes during long sessions. · Ten languages. English, Chinese (Simplified & Traditional), Japanese, Korean, German, French, Polish, Russian, Thai — communicate effortlessly across borders. · Personal prompt library. Save the writing styles, decision frameworks and industry templates you reach for again and again — an advisor that learns your rhythm. · Favorites & history. Star important conversations, archive by topic, and revisit anytime.

—— Private by design, quiet by choice

· Local first. Conversations live on your device by default — you stay in control. · End-to-end encryption. Accounts and traffic are encrypted in transit. Sign in with Apple is supported; you can even start anonymously. · No noise. No flashy popups, no manipulative ads — just generous whitespace and considered design.

—— What is new in v2.0.3

· A brand new Mode Selector guide that helps you get it right the first time. · Major stability and login improvements, with an automatic circuit breaker that isolates any unstable backend so the conversation never stalls. · Comprehensive performance and observability polish — faster cold start, less jank, faster fixes.

Chat4o is not just a chat app. It is the advisor who thinks first and speaks second. Keep it close, and let every decision feel a little calmer.
