List
Product copy & microcopy
Tools and references for onboarding, empty states, and error messaging — plus the boring infrastructure that keeps Figma strings and production strings identical.
1.
Claude
Draft and iterate on websites, graphics, documents, and code
Curator note
The workhorse. Give it a context block — product, audience, voice, banned words, and three real strings that are exactly right — and it stops sounding like every other AI-written product.
2.
Ditto
Manage product copy in one place and sync it into Figma and code
Curator note
The unglamorous, highest-ROI tool on this list. Copy lives in one place, syncs into Figma, exports for developers, and an entire recurring category of bug disappears.

UserOnboard
Source for User Onboarding teardowns
Curator note
Teardowns of real onboarding flows, annotated. The best way to learn why a sequence works rather than what it looks like.
4.
Growth Design
Growth & UX case studies in a comic book format
Curator note
Case studies in comic form covering the psychology behind specific product decisions. Genuinely good at explaining the reasons a piece of copy lands.
5.
Writer
Enforce brand voice and terminology across a whole organisation
Curator note
The answer when voice needs enforcing across an organisation rather than a single product surface — style guides and terminology checked where people actually write.
6.
Grammarly
The mechanical layer of writing, with a configurable style guide
Curator note
Still earns its place for the mechanical layer, particularly with a custom style guide configured. Catches the things you stop seeing in your own writing.
7.
Nielsen Norman Group
World Leaders in Research-Based User Experience
Curator note
The reference for error messaging, form labelling, and the research behind every microcopy convention you're about to argue about in a review.
8.
Checklist.design
A collection of the best UX and UI practices.
Curator note
Component-by-component checklists that include the copy considerations most teams forget — empty, loading, error, and permission states.

Digital Psychology
A free library of psychological principles and examples for inspiration
Curator note
The principles underneath persuasive copy, with examples. Use carefully; most of these patterns work and some of them shouldn't be used.
