Causal vs Chalked: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Causal and Chalked — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Causal
Causal Software Limited
An infinite AI canvas for creative planning, where notes, files, images and links sit in one spatial workspace an agent can read and build on.
Key features
- Infinite Spatial Canvas: A freeform, unbounded board where notes, images, links and files are arranged by meaning, so layout itself becomes the organisation rather than a folder hierarchy.
- Context-Aware Agent: The AI reads the whole canvas and understands how ideas connect, then answers questions and researches topics with the surrounding board as context.
- Native Output Generation: Prompts are turned into canvas content directly, with the agent creating notes, files and web-link cards and placing them where they belong instead of returning plain text.
- Rich File Previews: PDFs, Word and Adobe documents, markdown, spreadsheets, images and video up to 20 MB open fullscreen in-app, and markdown and CSV files can be edited in place and saved back to the file.
- Dual Text Editing: Quick notes live directly on the canvas while longer pieces open into a full-page editor, both sharing headings, lists, checkboxes, quotes, code blocks, highlights, images and links.
- Structure Tools: Collections pack related nodes into tidy columns, nested canvases give a sub-topic its own space, and an unsorted tray parks anything not ready to be placed.
- One-Click Sharing: Any canvas becomes a read-only link that recipients open without an account, covering nested canvases too, and sharing can be revoked at any time.
- Template Library: Ready-made boards for app flows, app plans, brand research, branding boards, competitor research, onboarding, storyboards, video briefs and plans, website moodboards and website plans.
Best for
- Product Planning: Map every screen in an app and the routes between them, then keep features, screens and shipping order in one view instead of three separate documents.
- Brand Development: Collect the brands, palettes and voices you are borrowing from, then settle type, colour and marks in one place the whole team works from.
- Competitive Research: Put rival products side by side with your own on a single board and find the gap you can actually take.
- Video and Film Pre-Production: Block out a shoot frame by frame, hand an editor references, tone and deliverables on one canvas, and follow a video from script to final cut with every asset attached to its step.
- Website Design Prep: Gather reference sites, type and colour a build should feel like, then lay out every page and its contents before the first component is built.
- Team Onboarding: Walk a new starter through the tools, files and people one frame at a time on a shareable board.

Chalked
Mates Rates Services Pty
Mac assistant that drafts the reply you'd actually send, grounded in the open conversation, your calendar and kept commitments.
Key features
- Context-grounded replies: Reads the open conversation via Accessibility and drafts the reply you would actually send
- Tab to insert: Prepared drafts land in the existing Messages composer and are inserted with a single Tab press
- fn to redirect: Hold fn and say what you want instead to steer the draft before inserting it
- Commitment ledger: Captured commitments keep their source and status, and superseded entries are marked rather than duplicated
- Calendar grounding: Pulls availability from your calendar so proposed times are real, not invented
- Global fn dictation: Works anywhere else on the Mac even outside eligible Messages threads
- No screenshots or recording: On-screen text is read through Accessibility and stays on your Mac
- Minimum context by design: Requests only the thread and verified facts relevant to the reply
Best for
- An agency operator answers a client asking about a delivery date without re-checking the calendar and the approved budget by hand
- A consultant returns to a client thread days later and replies with the engagement's commitments intact instead of rebuilding them from memory
- A founder moves between customer, investor and team conversations in one sitting without losing which promise belongs to whom
- A team lead confirms a meeting time that is actually free because the draft was written against the live calendar
- Someone dictates a longer message into any Mac app using the global fn shortcut rather than typing it out
- A user corrects a suggested reply by voice — changing a day or a cap — before it is inserted and sent
