Built with Calanthe
Four AI models tuned for different kinds of work, plus vision, code execution, web search, agents, and MCP integrations — all in one workspace.
Switch between models mid-conversation. Each model has its own strengths — and its own cost per token, which is why your monthly allowance is sized to the model mix.
Fast everyday assistance
Balanced reasoning + speed
Deep analysis, 1M context
Maximum capability
Every Calanthe model can call into a shared set of capabilities. Mix and match them in a single conversation.
Drop in PDFs, screenshots, photos, spreadsheets, code files. Calanthe reads them — extracts data, summarizes long documents, transcribes handwritten notes, explains diagrams, reverse-engineers UI mockups. Supported formats: PDF, PNG, JPEG, plain text, JSON, XML.
Limits: 5 files per message · 20 MB per file · 50 MB per batch.
Calanthe runs Python in a sandboxed environment — analyse data, generate charts, transform spreadsheets, run quick simulations, validate calculations. The result of every run is shown inline with the code that produced it, so you can verify the logic and iterate.
Available on: Pro+ and Power tiers.
For questions about today, this week, or anything time-sensitive, Calanthe searches the live web and brings back current sources. Citations are included so you can verify or follow the trail. Calanthe decides when a question needs fresh information and searches automatically.
Available on: Every plan, including Free.
Build multi-step agents that take actions in your tools — query a database, post a message, file a ticket, update a spreadsheet. Calanthe speaks Model Context Protocol (MCP). Power users can connect remote MCP servers to bring outside tools into a conversation (advanced setup).
Available on: Power tier.
Tap the microphone, say what you need, and hear her answer back in her own voice — warm, clear, and never intimidating. Hands-free conversation mode keeps the exchange going while you cook, drive, or pace around the room thinking.
Press the mic and talk naturally. Calanthe transcribes you in seconds — no typing required.
Your words go to the same models that power chat — full context, full capability, nothing dumbed down.
Replies are spoken in Calanthe's own voice. Turn on automatic playback for a true back-and-forth conversation.
Included with every paid plan: up to 400 voice messages/month on Pro, 800 on Pro+, and 2,000 on Power. Enable it in Settings > Speech.
A rough rule of thumb — switch if your task hits a different row.
