Tangent is the AI workspace for people who think in projects. Create Slack-style channels — #vacation, #therapy, #work — each with its own AI personality. When a response sparks a new idea, branch it into its own thread without losing your place. Switch between GPT-4o, Claude, and Gemini in the same workspace.

Three steps to an AI workspace that actually stays organized.
After signing in, tap "Create your first channel" (or the + button in the sidebar on desktop). Name it #vacation, #therapy, #work — whatever fits. Each channel is completely separate with its own AI personality.
Pick whichever AI model you want for each conversation. Switch mid-chat if you want a second opinion. All three are included, no extra subscriptions needed.
When the AI says something worth exploring, hit Branch to spin it off into its own thread. Go as deep as you want — your original conversation stays exactly where you left it. No other AI does this.
Tangent is the only AI workspace with conversation branching — explore any tangent without losing your main thread.
Hit a tangent mid-conversation? Branch any AI reply into its own independent thread. The original conversation continues uninterrupted.
Create dedicated channels for each project, topic, or life area. Vacation planning, therapy journaling, code reviews — all separate, all searchable.
Start with Gemini, switch to Claude for a nuanced take, then ask GPT-4o to summarize — all in the same channel without losing context.
Find any message across all channels and threads instantly. Keyword highlighting shows exactly where your match lives.
Export any channel or thread as Markdown, PDF, or JSON. Your conversations are yours — take them anywhere.
Set a system prompt per channel. Make one channel a patient therapist, another a brutally honest editor, another a travel guide.
Connect your own OpenAI, Anthropic, or Google key and bypass usage limits entirely. Your key routes directly to the model — your cost, your control, no middleman.
