Finding the right document brings relief. Understanding it helps you move forward.

What problem it solves

People managing their own or their family’s paperwork who want things under control without spending their evenings sorting documents.
Letters pile up, PDFs disappear into inboxes, and important information is hard to find when it’s needed. Even finding the right document doesn’t always make its meaning clear. The result is wasted time, postponed tasks and the nagging feeling that something important has been overlooked.
ExplainThisDoc helps them find and understand their paperwork without maintaining a filing system.

Your digital life is scattered — files in one place, notes in another, meetings somewhere else, and finding anything means remembering which app you left it in. Fabric tackles that fragmentation head-on: it's an AI workspace, billed as 'the AI workspace that thinks with you,' serving as one intelligent hub for your files, notes, ideas and meetings.

One hub for everything

Fabric pulls your scattered content into a single place and supports a huge range of file types — PDFs, videos, emails, documents, images and more — so nothing lives in isolation. A visual canvas lets you organize content spatially, and semantic search works across 50+ integrated apps, meaning you can find things by what they're about rather than remembering exact filenames or which service they're buried in. For anyone drowning in digital clutter, that unified, searchable hub is the core appeal.

An AI that actually does things

Fabric's AI assistant understands your work and can execute tasks on your behalf, and you can create custom agents with distinct personalities to handle research, summarization and automation independently. That's a step beyond a passive search box — it's an assistant that can go off and do work with your knowledge, from summarizing a stack of documents to running research. It even generates AI meeting transcripts, folding your calls into the same searchable brain.

Built for thinking

With task management (priorities and reminders) layered on top, Fabric aims to be both your knowledge base and your command center. It sits in the same 'second brain' space as tools like Reflect and AppFlowy, but leans hardest into AI that connects and acts on everything you've collected.

Flexible for many kinds of work

Because it handles so many content types and use cases, Fabric adapts to very different workflows — research, design, writing, legal, founding a company — rather than forcing one rigid structure.

Who it's for

Fabric suits thinkers, researchers, designers, students, founders, marketers, content creators, developers and lawyers — plus teams across creative, research, agency, startup and consulting work who want their scattered knowledge unified and made actionable by AI.

Pricing

Fabric is freemium with a prominent 'Try for $0' option and paid tiers for heavier use. Starting free lets you connect your content and experience the semantic search and AI agents before deciding to upgrade.

Bottom line: Fabric is an AI workspace that unifies your files, notes and meetings into one searchable hub — then adds custom AI agents that can actually act on it, making it a genuine 'second brain' for the AI era.
