Corca: a more natural way to write math digitally

🧮 Corca: a more natural way to write math digitally

Corca is a WYSIWYG math editor with an ambitious goal:

to make writing mathematics as natural and fluid as writing plain text.

Instead of LaTeX commands, you can type expressions using near-natural language

like integral from 0 to 1, x over 2, or sqrt(3), and Corca converts them

instantly into structured, two-dimensional mathematical notation.

🚀 What really stands out

Extremely fast incremental parsing
Native 2D structures (fractions, integrals, sums, matrices)
A semantic cursor that understands mathematical structure
A writing experience very close to pen-and-paper
Clean LaTeX export (confirmed by the creators)

🧠 Why this matters

Even in 2026, writing math digitally is still painful.

LaTeX is powerful but not human-friendly.

Most visual editors are either slow or limited.

Corca attacks the real problem:

reducing the cognitive gap between thinking in math and typing it on a keyboard.

🔬 Current status

Corca appears to be a web-based editor in preview/private access,

but as a technical and UX concept, it’s one of the most promising approaches

to mathematical input we’ve seen so far.

If it scales well and keeps high-quality LaTeX export,

it could become a serious tool for students, educators, and researchers.

🔥 Postman lança o AI Agent Builder: Uma nova era para criar agentes conectados a APIs

Rafael Santos — Sat, 29 Nov 2025 11:44:54 +0000

Postman acaba de lançar o AI Agent Builder, uma plataforma que conecta APIs e IA de forma nativa e reduz drasticamente o tempo entre ideia, protótipo e produção.

O diferencial é a integração total: descoberta de APIs, ferramentas MCP, orquestração, testes e execução.

É um ambiente completo para criar agentes realmente úteis — muito além de simples chatbots.

🚀 Por que isso importa?

Porque desenvolvedores agora podem transformar qualquer API em uma ferramenta plugável para IA, criando agentes com autonomia real e integração com sistemas existentes.
