Keep the main thread intact
Why AI chats fall apart
Ask a question. Get a multi-part answer. Ask about one part of it — and the conversation forgets the rest. You either lose the thread, or you open a new chat and re-explain everything from scratch. APReason does neither. Every paragraph can branch into its own focused thread, with its own context — and merge back when you're done.
01 · One conversation
The complete answer stays visible.
02 · One paragraph
Choose the exact point to explore.
03 · Focused branch
Ask follow-ups with context preserved.
04 · Main thread
Merge back without losing the structure.
Inside every branch
Follow the question wherever it leads.
Branching keeps the investigation structured. These capabilities help you explore each focused thread.
Run and debug code
Paste a broken snippet, get it executed in a sandbox, the real error read, causes ranked, and the fix verified with a before/after diff.
Thought map
See every branch you’ve opened, visually, and how it connects back to the original question. Export as PDF, PNG, or SVG.
Analyze files and images
Attach supported files or drop in an image, and branch a follow-up on any of it.
Live web search
Time-sensitive questions get looked up as you ask, with source links included.
One-click report
Export any thread as a clean Markdown write-up. Debugging branches can also generate a pasteable bug report.
Built for anyone whose thinking has more than one step.
Debugging a stubborn bug
Branch into ‘why is this the cause?’ without losing the other hypotheses.
Planning a multi-step project
Dig into one phase without the plan falling apart.
Researching a topic
Chase a tangent, then return to the main thread with everything intact.
Working through a hard concept
Ask ‘wait, why?’ on any one part, without restarting the explanation.
