How it works

From blank page to shared draft.

Four steps, and you stay in control of every one of them.

  1. 1

    Write in blocks

    Type / to drop in callouts, Mermaid diagrams, equations, flashcards or quizzes. Every block has a stable id, and everything saves as you type.

  2. 2

    Ask an agent

    Pick an agent and choose Ask or Agent mode. In Agent mode it reads, searches and edits section by section while you watch. Stop any time, undo in one click.

  3. 3

    Write together, live

    Teammates and AI show up as avatars with cursors. Edits merge without overwriting each other, and comments and reactions land right next to the text.

  4. 4

    See it, undo it, share it

    The Activity panel shows who changed what with word-level diffs, and any block can be reverted. Then share a live link or export PDF and Word.

Everything inside

Everything you write. One forge.

The full feature list, grouped by what you are trying to do.

AI agents

An AI team that knows your document.

Pick an agent, choose Ask or Agent mode, and point it at a selection or the whole page. Agents work with tools: read blocks, search, then make one focused edit at a time. The server only checks the edits, and your browser applies them, so you watch the page change.

Assistant

Answers questions about your document and helps with anything in it.

Writer

Drafts new sections and expands outlines into full text.

Line editor

Tightens wording and fixes grammar without changing your meaning.

Formatter

Adds structure: headings, lists, callouts and consistent styling.

Reviewer

Finds gaps and weak spots, and fixes them when you say so.

Tutor

Turns notes into flashcards and quizzes and explains hard parts.

Translator

Translates a selection or the whole page and keeps the formatting.

Foxia stylist

Applies the Foxia sticker look with serif accents and labelled callouts.

Custom agents

Save reusable instructions, pick a preferred model, and even expose the agent to MCP.

Bring your own key

OpenAI, Anthropic, Google, Mistral, Groq, OpenRouter or any OpenAI-compatible URL. Keys are encrypted.

Compare mode

Send one request to two models. Neither touches your document until you pick an answer.

Pipelines

Chain agents, like Write then Polish or Write then Foxia style. The chain stops if a step needs your approval.

Usage tracker

Tokens, estimated cost per day, model, document and agent. Set a monthly budget and export CSV.

Undo and revert

One undo restores the state before a run. Revert any block, and your later human edits are never destroyed.

Live sync

Humans and AI, same page.

People edit through a shared live document that merges changes. An AI edit through MCP is version-checked first, so it can never silently overwrite what you just typed.

When people edit

  1. You type
  2. Merged live
  3. Everyone sees it
  4. Saved automatically

When an AI edits

  1. AI edits via MCP
  2. Version checked
  3. Live feed event
  4. Your tab pulls it in
Comments and reactions on any block Follow a collaborator Search across all documents Study blocks built in
MCP server

Your docs, inside every AI chat.

Connect Claude, ChatGPT, Copilot and other assistants to DocForge with one URL. Ask them to find, read, summarise or update your documents without leaving the chat.

  • Secure OAuth sign-in. Your password is never shared.
  • Edits land block by block, so formatting stays intact.
  • Start read-only. Grant editing only when you want it.

The 21 MCP tools

Safety rails on every AI write

  • Compare-and-swap writes: a stale AI is refused, never overwrites you
  • Large-deletion guard needs explicit confirmation
  • Rate limits per user and per document
  • Comments are treated as data, never as instructions
  • Advisory claims warn when two AIs overlap
  • Every call is audited without logging your content
Trust and control

You can see it. You can undo it.

The database decides

Row-level security on every table. The editor, the MCP server and every AI tool call run as you, never as a super-user.

Keys stay sealed

Your API keys use AES-256-GCM envelope encryption. Only you, running your own agent, can ever decrypt one.

OAuth, with your say

AI apps connect with OAuth 2.1 and PKCE. You choose read-only or read and write, and you can revoke it.

Nothing happens in secret

Every AI action is a visible, attributable event. See it live, review the diff, and revert it.

Documents are protected by row-level security and encrypted in transit. They are not end-to-end encrypted, which is what lets search, export and AI work.

Templates

Start with structure.

Pick a document type and get a ready-made outline in continuous or paged layout.
