Blint makes AI-coding
predictable and scalable.

Define your best design ideas as patterns, document the purpose behind your code, and enforce both consistently — across every file, every commit, every contributor.

The core idea

AI-coded projects need guardrails to scale well.

Blint introduces controlled code — guardrails that enforce your design opinions automatically. Patterns define how code should be written. Documentation defines why it exists. Enforced consistently across every file, every commit, every contributor.

Pattern — how code should be written

Async Loading Component
src/components/**/*.tsx

Documentation — why it exists

Authentication flow

Everything in Blint

One tool for governed, agentic development

Patterns and documentation define the rules; embedded Claude Code does the work; coverage and conventions keep it honest.

Compliance coverage map

A treemap of your codebase shows where patterns and docs are thin, so you can see what isn't yet under control.

Coding conventions

Turn on principles like DRY, KISS and YAGNI, and dial the rigour up or down to match the project.

Built-in Claude Code

Work on specs and co-author your patterns, without leaving the app

Claude Code runs inside Blint. Use it to implement your specs, and to refine your reusable patterns and documentation in conversation.

  • Implement specs — run Claude Code on a spec and follow its work live

  • Co-author patterns — shape your reusable patterns and docs in plain English

Claude subscription required

Implement the add-auth spec
Read src/auth/login.ts
Edit src/auth/session.ts
Bash yarn test auth

Added token refresh and wired it into the session guard. Tests pass.

You

Extend the async loading rule to cover custom hooks too.

Claude

Added src/hooks/**/*.ts to the globs and a note on hook loaders.

Async Loading Component v4

Switch between accounts

Keep several Claude logins on hand and switch between them without losing the conversation.

Colour-coded projects

Each project gets a colour every Blint window adopts, so you always know which repo you're in.

A clear, spec-driven workflow

From draft to review, with your patterns enforced

Plan each change as a spec and follow it across a board, with Blint checking your patterns as the code is written.

  • Kanban board — move specs through drafting, implementing and reviewing

  • Pattern enforcement — checks run as code changes and flag drift before it ships

  • Isolated runs — each spec builds in its own worktree or copy

One session at a time

A per-directory baton runs sessions one at a time so parallel work doesn't collide — showing who holds it and who's waiting.

~/payments-api
add-auth holds baton
1 fix-pagination waiting
2 rate-limiting waiting

Isolated environments

Run each spec in a git worktree, a copy, or the original folder, so parallel work doesn't step on itself.

CLAUDE.md management

Keep your AI's context current without manual editing

Blint manages its own sections inside your CLAUDE.md — the file Claude Code reads for project guidance. Your existing content stays untouched, and one click syncs the managed sections.

  • Patterns — routes Claude to the right pattern files based on glob matchers

  • Documentation — key points from your colocated docs, kept in sync automatically

  • Conventions — industry principles like DRY, KISS and Fail Fast, toggled on per project

  • Pointers — project-specific notes like "use AWS profile personal" or "run tests with --watch"

Add a pattern that enforces our async loading wrapper on every data-fetching component

Project script runner

Every script in your repo in one panel — click to run dev, test or build.

dev yarn dev

build yarn build
lint yarn lint
deploy yarn deploy

Token optimisation mode

Cut token use — Blint drops the bulky parts of the context when it next refreshes the cache.

Sync patterns across projects

Patterns are versioned markdown you can sync between projects in a click, keeping codebases aligned.

A menu-bar status and system notifications tell you what's running and what needs your input, so you can leave Blint working and come back when it's ready.

Community patterns

A pattern is your take on how something should be done — targeting specific files and enforced automatically. Share yours across projects, or pull vetted ones from the community registry.

A General-Purpose Async Loading Component for React Query

One way to centralise loading, error, and retry UI for React Query without leaking query state into every component.

AI-Managed Documentation That Lives in Your Codebase

Embedding markdown documentation directly in your app and letting Claude maintain it produces docs that stay accurate, include real diagrams, and don't rot.

API Mocking Pattern for React and Storybook

A clean pattern for swapping between real and mock APIs without polluting your components with mocking logic.

Data Model handling in TypeScript

A pattern for shared, runtime-validated data models that catch issues early and keep frontend and backend in sync.

Demo Driven Development

Building components in isolation with comprehensive demos catches edge cases that unit tests miss and ensures your UI handles failure gracefully.
