Fylun Workspace
The office suite that thinks.
Fylun Workspace is a full productivity suite — documents, spreadsheets, notes, presentations, drawings, databases, calendars, and forms — with an AI chat pane built into every tab, not bolted onto a notepad. Open a spreadsheet next to a chat thread in a split view, and ask a model to read the data while you keep editing.
FREE TIER — NO CREDIT CARD · ONE WALLET, EVERY SURFACE
A real engine, not a grid.
Roughly 105 built-in functions, named ranges, conditional formatting, and cross-sheet references — with an AI that writes the formula where you ask for it.
What's inside.
Documents
Rich-text documents with the same editing model as Google Docs or Word, plus an AI pane docked alongside the page for drafting, rewriting, and summarizing without copy-pasting into a separate chat window.
Spreadsheets
A full spreadsheet engine with roughly 105 built-in functions, named ranges, and conditional formatting — not a stripped-down grid. Ask the embedded AI to write a formula, explain one, or clean up a column, and it edits the sheet directly.
Notes
Obsidian-style linked notes with backlinks and a graph view, for the kind of note-taking that outgrows a single document.
Presentations & drawings
Build slide decks and freeform drawings or diagrams in the same workspace as your docs and sheets, with AI able to draft a first pass of either from a prompt.
Databases, calendars & forms
Lightweight structured databases, a calendar view, and forms for collecting input — enough structure for a small team to run projects without a separate app.
Split-view AI pane
Every document type opens with an optional AI chat pane in a split view — ask questions about what's on the page, or work in a document and a conversation side by side, without switching tabs or losing context.
What it retires.
Replaces Google Docs, Sheets, and Slides, plus a Notion-style notes app and a separate AI chat tab — one workspace, one login, one subscription.
Common questions.
Is Fylun Workspace a replacement for Google Docs and Sheets, or does it work alongside them?
It's built to be a full replacement — documents, spreadsheets, presentations, drawings, notes, databases, calendars, and forms all live in Workspace under one account. It isn't tied to Google's or Microsoft's file formats, so it works as a standalone suite rather than a plugin for either.
What can the embedded AI chat pane actually do inside a document?
It has context on whatever you have open — it can draft or rewrite a section of a document, write or explain a spreadsheet formula, summarize a long note, or answer questions about the data in a sheet, and it makes the edit directly rather than just describing it in chat.
How capable is the spreadsheet engine?
It supports roughly 105 built-in functions, named ranges, and conditional formatting — the core feature set most spreadsheet users actually reach for, not a bare-bones grid with SUM and AVERAGE.
Which AI models power Workspace?
The same model catalog as the rest of Fylun — 50+ chat models across every major provider, selectable per document, billed from the same credit wallet as chat, Studio, and every other surface.
