The problem with AI tools today
✕You paste context. Again. And again.
Project Memory injects your context into every chat automatically. The AI knows your company, your constraints, your priorities — without you re-explaining.
✕You open six tabs and lose track of all of them.
Koffein's multi-column workspace keeps every thread visible, organised by project, scrolling independently — all at once.
✕You scroll through 800 words to find the one line that matters.
Every AI response collapses to 2 lines by default. Scan your entire workspace in seconds. Expand only what earns your attention.
✕You pick the wrong model, or spend 30 seconds deciding.
AUTO routing assigns Research → Claude, Technical → GPT-4o, Writing → Claude. You see the routing hint before you send. Override whenever you want.
What's inside
Not a smarter chatbot. A parallel AI workspace with structure, memory, and flow built in from the start.
Parallel chats, always open
Run your fundraise, your product sprint, and your content calendar simultaneously. Each column is independent — its own model, workstream, project context, and scroll position.
Project memory that actually sticks
Write your context once — who you are, what you're building, what constraints matter. Koffein injects it automatically into every chat in that project. The AI never forgets.
Scan in seconds, not minutes
Every response starts collapsed at 2 lines. Your entire workspace — six threads of thinking — fits on one screen. You decide what deserves a full read.
Smart model routing, no decisions needed
Koffein routes each message to the right model automatically: Claude for strategy and writing, GPT-4o for technical and execution. You see the routing hint. You override when it matters.
Prompt optimization, transparently
Your message is rewritten for the target model before it sends — XML structure for Claude, conversational scaffolding for GPT. You see exactly what changed in the diff.
Branch and Challenge in one click
Select any text in any response. Branch it into a focused new thread. Or hit Challenge — Koffein forces the model to argue against its own answer, surfacing assumptions you'd otherwise miss.
The thinking assistance layer
Research shows people accept AI outputs without scrutiny 73% of the time. AI access inflates confidence by +11.7pp — even when the model is wrong. Koffein is the only AI workspace built with features specifically designed to keep your own brain in the loop.
Decision Safety Badge
Every AI answer is rated LOW, MEDIUM, or HIGH based on workstream, model, and optimization level. Tap to see exactly how the output was grounded — model reasoning, evidence-based, or speculative. Always visible. Never skippable.
73% of AI outputs accepted without scrutiny
Uncertainty Nudge
On Strategy and Fundraising chats, a one-click prompt appears: "This answer depends on assumptions. Want alternatives?" Click it — Koffein opens a branch chat that argues against the original answer.
Deliberation doubles override rates
Your Take field
When you save a note from a chat, you're asked: what do you actually think? One sentence. No formatting. This single habit — writing your own view before accepting an AI answer — is the most effective guard against cognitive surrender.
Writing your view prevents blind adoption
Founders
Fundraise, product and hiring — in parallel, with context that doesn't reset between sessions.
Consultants
Six client threads at once. Project memory means no re-briefing the AI every session.
Researchers
Branch hypotheses, challenge findings, track evidence. Decision Safety tells you when to trust.
Operators
GTM, technical, and content — side by side, routed to the right model automatically.
