Steer your AI before it builds
You already use AI to make the work, and it comes back inconsistent, off brand, occasionally rogue. Sidenote loads your brand as context before the agent builds, then reviews what comes out.
Works with Claude, ChatGPT, Gemini, and anything that speaks MCP.
Your brand, as context
The half a markup tool cannot copy.
Loaded before the first draft
Import your brand once and every build an agent makes starts on brand, instead of being corrected after. Prevention, not cleanup.

Bring your brand in
Upload a brand book or paste a URL. Sidenote reads out the colours, type, voice and assets.

Structured data your agent reads before it builds.
It becomes a brand spec
Not a slide about your brand: structured data an agent obeys. Colour tokens, voice rules, assets.
Templates from your work
Your shapes, not just your brand.
Your structures, reusable
Turn a document or a deck you are already working on into a template an agent can fill. Or bring your own.

Templates from your documents
A document or deck you already work in becomes a reusable, branded template.
Your agent fills them, on brand
A branded deck in your own template, natively editable, ready to review and export to PowerPoint.
Comment, review, ship, together
Everyone can markup. Not everyone makes it frictionless.
Review without the friction
Comments anchor to the element and travel across versions. Your clients review without an account.

Anchored to the element
A comment lands on the thing it is about, and travels with it across versions.
Your clients review without an account
Share a link. They comment in place, no signup. Try it here.
Bring it in, your way
Three doors in, for three kinds of user.
Connect a tool to this brand

Paste a URL
The easiest way in, for everyone. Your agent connects to your brand by URL.
Or take the files
DESIGN.md, tokens.json, agent rules, a cheat sheet. The brand in your repo, with no connection to keep alive.
Into your workflow
For developers: mint a key and call it from whatever you already run.
