Who is Aswin Kumar?
Founder, Bullet.so. Known for building Bullet.so, the Notion website builder behind blogs, knowledge bases and gated member sites, and for publishing its CSS class reference as free developer docs.
This page recognises Aswin Kumar for what they have contributed to the Notion community. It is written independently, it is not an endorsement, and it does not mean they use thePlus.so.
“I write everything in Notion and I want the published version to behave like a real website, so I need to know whether Bullet.so and the person running it are worth committing my domain to.”
This page covers where Aswin started, what Bullet.so does that Notion publishing leaves out, and what he has shipped since. It does not price him against every other Notion site builder, and it does not review the product on your behalf: the public showcase and the free templates are the quickest way to judge that yourself.
In April 2021, close to two years before Bullet.so existed, Aswin Kumar launched Disbug on Product Hunt. It was a Chrome extension that recorded a browser bug with voice narration and posted the recording into Jira with the console output and technical logs attached. The whole product was about a handoff: turning something one person could see on their screen into something another person could act on without a call.
On 15 March 2023 he launched Bullet.so with a flat tagline, "Build professional website from Notion. One time price today." The premise was that the Notion page already held the finished writing and the missing pieces were a domain, a design and the metadata that search engines read. Bullet.so took on those pieces.
Bullet.so now runs blogs, knowledge bases, portfolios and directories. Its customer stories include Requestly, the Y Combinator backed developer tool, along with Datakrew, Sahayak and ReadonlyREST, several of which describe moving off WordPress to get there. Plans start at $9 a month, $19 adds membership gating and multilingual sites, and a separate done for you build starts at $499.
His first product was about handing work to someone else
Disbug existed because of the gap between spotting a bug and describing it well enough for a developer to fix. The extension captured a screencast with narration, bundled console output and technical logs with it, and dropped the package into the tracker in one click. Aswin ran it as founder, and the habit shows up again in everything he built afterwards: find the step people do badly by hand, and let the software carry the tedious half of it. The Disbug site still points to his personal X account, @aswin_db, where he labels himself as building in public.
Notion had the writing, the web had none of the plumbing
Bullet.so connects to a Notion page and publishes it as a site with a custom domain, page metadata, automatic social sharing cards and fast load times. What it sells is everything Notion does not hand you at publish time: password protection, email capture, content gating for paying members, multilingual versions of the same site, and block level control over how each Notion element renders. The showcase sorts what people actually ship into blogs, knowledge bases, landing pages, portfolios and directories, which reads as an honest map of what Notion writing turns into once it leaves the workspace. The pitch on the front page is aimed squarely at the person who writes comfortably in Notion and then winces at the public version.
The class names are public, and so are the templates
Bullet.so keeps a documentation area called Nuggets, described as bite sized tips, tricks and API references. It lists the CSS classes and variables behind a Bullet page and walks through restyling individual Notion blocks: callouts, toggles, tables, code blocks, the navbar, the footer. That is reference material a Notion user would otherwise have to reconstruct by reading page source. Sitting next to it are more than twenty templates, seven of them published free on Notion's own template marketplace under the Bullet.so creator profile, plus a Discord server and a YouTube channel where the how to material lives.
Now the styling is a prompt
Bullet AI was documented on the Bullet.so blog on 25 September 2025 and now leads the homepage. It takes a plain Notion page and sets the colors, fonts and spacing automatically, accepting a prompt, a reference image or raw CSS as the instruction, and it ships to Pro accounts. Aswin has kept building alongside it. Mindmap.so, launched in October 2024 and built on Excalidraw, imports Notion pages and databases onto a whiteboard so the links between them are visible, and it is free. Disbug was rebuilt for AI coding agents, capturing a browser bug with screenshot, console errors, network logs and DOM context in the form Claude Code or Cursor can use, and in March 2026 he launched The Claw Guy, a directory of OpenClaw skills, plugins and tools.
Why Aswin Kumar is on this list
He gave the Notion community a route from a written page to a site that holds up in search and behind a paywall, and then published the internals to go with it: the CSS class and variable reference in the Nuggets docs, seven free templates on Notion's own marketplace, and a showcase of live sites people can study before they build. Several businesses in his customer stories used it to leave WordPress and keep writing in Notion.
