Introducing Cereby Mini: Your Document AI

How we built an in-document AI assistant optimized for edit safety and writing flow

The Problem: Context Switching Breaks Writing Workflows

Traditional AI writing flows require constant context switching: read in one surface, chat in another, then manually copy edits back into the document. That loop creates friction, introduces copy/paste errors, and slows revision cycles.

We wanted a system that could operate directly on document context while preserving user control over every mutation.

Design Goals

Keep AI actions grounded in the active page, selection, and attached context.
Support both generation and transformation in a single in-document workflow.
Require explicit user acceptance for document mutations.
Maintain high utility for study-focused writing tasks.

What Cereby Mini Does

Cereby Mini is an in-document assistant that can create, transform, analyze, and refine content without leaving the editor surface.

Core capabilities:

Context-aware operations: current page, selected text, or full document scope.
Document mutations with guardrails: insertions, rewrites, replacements, and restructuring.
External context injection: page references and file attachments.
Review-first editing: proposed changes are shown in a diff before acceptance.

This architecture keeps interaction speed high while preserving editorial control.

Capability Areas

1. Structured Content Creation

Generate structured artifacts (notes, outlines, study guides) directly in the document to reduce formatting overhead and improve consistency.

How it works:

Ask for Cornell notes, outlines, Q&A formats, summaries, or step-by-step guides
Cereby Mini generates structured content directly in your document
Perfect for study materials, essay planning, and meeting notes

Example: "Create Cornell notes on photosynthesis" generates a usable two-column layout with cues, notes, and summary blocks.

2. Grammar & Style Checking

Get more than a spell-check. Cereby Mini analyzes grammar, spelling, punctuation, and style — and explains each suggestion.

How it works:

Request a full grammar check or focus on a section
Review passive voice, redundancy, sentence variety, and wordiness
Apply improvements with one click, or refine in chat

Example: "Check grammar and improve writing style in the introduction" → You see issues with explanations and optional rewrites.

3. Content Transformation

Rewrite content in different tones, reading levels, or perspectives without losing your meaning.

How it works:

Ask for academic, casual, formal, or technical tone
Adjust reading level from elementary to expert
Shift perspective (e.g., first person to third person)

Example: "Rewrite this paragraph in formal academic tone" → The same ideas, polished for your audience.

4. Content Extraction

Turn long notes into organized reference material. Extract definitions, formulas, examples, questions, or key points into glossaries and reference sheets.

How it works:

"Extract all definitions into a glossary"
"Extract all formulas into a reference sheet"
"Create a summary of the key points"

Example: After a long chapter, one request gives you a clean glossary or formula sheet for review.

5. Document Analysis

Understand how your document reads and how healthy it is. Get readability metrics, document health scores (A–F), and structure analysis with clear recommendations.

How it works:

Request a document health score or readability analysis
See completeness, quality, structure, and citation coverage
Use the suggestions to plan your next edits

Example: "Calculate document health score" → You get a grade plus actionable tips to improve.

6. STEM Support

Notes and assignments often need symbols, units, and formulas. Cereby Mini can insert math symbols, convert units, format chemical formulas, and help build scientific tables.

How it works:

"Insert integral symbol" or "Convert 5 meters to feet"
"Format all chemical formulas (H₂O, CO₂)"
Create data tables for lab results or calculations

Example: "Create a data table for enzyme activity results" → A properly formatted table appears in your document.

7. Math Problem Solving

Get step-by-step solutions and explanations. Type a problem or attach an image; Cereby Mini solves it and shows the work.

How it works:

Type: "Solve: 2x + 3 = 15, show all steps"
Or attach an image of a problem via 📎 and ask for solutions
Request similar practice problems or a formula reference sheet

Example: Attach a photo of homework → Receive full solutions with explanations, then ask for more practice.

8. Full-Page Editing

Insert, edit, delete, or replace content anywhere — or ask for a full-page rewrite. Cereby Mini can change the whole document when you need it.

How it works:

"Replace the introduction" or "Clear the page and start over"
"Add a conclusion that summarizes the main points"
Every change is proposed in a diff; you accept (Y), reject (N), or ask for tweaks in chat

Example: "Rewrite the whole page in simpler language" → You see the full diff and decide what to keep.

9. Add Context & Import Resources

Give Cereby Mini more to work with. Use @ to attach pages from the current document and 📎 to attach files from your resource library (or upload with +). Cereby Mini can read and analyze attachments, create notes from PDFs, solve math from images, and combine multiple sources.

How it works:

Attach a PDF, then: "Create comprehensive notes from the attached PDF"
Add pages with @, then: "Use the pages I added as context to improve this section"
Combine document pages and external files in a single request

Example: Attach a textbook chapter → "Extract all main concepts and create a study guide" → Notes and structure tailored to that material.

10. AI Text Detector & Humanizer

Check how much of your document reads as AI-generated and, if you want, make it sound more natural.

How it works:

Run the AI Detector (e.g., from the Document AI chat or scan button) to see scores and reasons
Select text and ask to "Humanize this section" for more natural phrasing
Useful for authenticity checks and academic integrity

Example: After drafting with AI, scan the document, then humanize specific paragraphs so they pass common detectors.

How Cereby Mini Fits Into Your Workflow

Inline and in the Modal

Inline (Cereby Mini bar): Select text or press Space next to a word to open the quick bar. Ask for an explanation, rewrite, or action on the selection without opening a full chat.
Full Document AI chat: Open the Document AI panel when you want to work with the whole document, attach files, or have a longer conversation. Same assistant, more space and context.

Both use the same Cereby Mini — same capabilities, same diff-and-confirm flow. Choose inline for quick edits and the modal for deeper work.

Review Before Applying

When Cereby Mini proposes an edit, you always see a diff view. You can:

Accept (Y) — Apply the change
Reject (N) — Keep your original
Chat — Ask for a different wording or approach

Nothing is applied until you accept, so you stay in control.

Tips for Getting the Most Out of Cereby Mini

Be specific — "Check grammar in the introduction section" works better than "check document."
Use preview — For mass replacements, ask for a preview first so you can confirm before applying.
Add context — Use @ for pages and 📎 for files; better context leads to better edits and answers.
Iterate — Make small changes, review the diff, then ask for more. You can always say "make it shorter" or "more formal."
Start with templates — Cornell notes, outlines, and Q&A formats give you structure in one request.
Combine features — Try: "Check grammar, analyze readability, and extract key points" in one go.
Review every diff — Accept only what you want; use Chat to refine until it matches your intent.

What Makes Cereby Mini Different?

Document-Native

Cereby Mini is built for the document. It uses the current page, selection, and attachments as context, so it doesn’t treat your request in isolation. That means more relevant suggestions and edits that fit your existing content.
