Slides.com
Hosted HTML presentations with collaboration, embeds, and developer controls
Slides.com's solo core is compact: build a browser-based web presentations editor with drag, resize, connect, keyboard shortcuts, autosave, and SVG or PNG export. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on interaction polish, collaboration.
Build verification: not recorded. How we judge buildability
What you give up
- multiplayer cursors and comments
- large template libraries
- high-fidelity import and export
- presentation and enterprise controls
Why people still pay
Slides.com: The shapes are easy; customers pay for low-friction editing, reliable exports, collaboration, and a canvas that never fights them.
Your build guide
The stack, security requirements, and agent rules for a focused replacement.
Before you start
- Runtime and tools: TypeScript, React, SVG or Canvas and IndexedDB with a versioned JSON project format.
- Before starting: A browser with IndexedDB, licensed example assets and fonts, and an agreed output size.
Use these project rules and optional skill references alongside the prompt. Review each skill before adding it to your agent; the AGENTS.md export includes the same guidance.
Project rule — domain: Store Deck, Slide, Block, SpeakerNote and Theme; notes are excluded from audience export unless explicitly requested and slide order is independent of block IDs.
Project rule — scope and recovery: Start with a small block set and local presentation mode. Remote control, live audience features and arbitrary embeds require separate security and compatibility work.
Project rule — acceptance: Add a long code block and private speaker note, then export and present on a narrow screen; flag overflow and keep the note out of the public deck.
Project rule — delivery: document real setup commands and permissions; do not claim a build, accuracy level, performance result or security certification that has not been demonstrated.
Recommended skill: vercel-composition-patterns — separate document tools, property inspectors and export controls into explicit reusable React components. Follow the maintainer's installation instructions and match its requirements to the chosen runtime.
Recommended skill: web-design-guidelines — review keyboard access, focus, validation, error recovery and the readable work/review interface or HTML report. Follow the maintainer's installation instructions and match its requirements to the chosen runtime.
Implementation plan
Phase 1
Pin the working slice and create its example input: Create HTML-style slides from text, images and code blocks, navigate with keyboard controls and export a portable presentation. Confirm setup: A browser with IndexedDB, licensed example assets and fonts, and an agreed output size.
Phase 2
Implement persistence and write-time invariants before decorating the UI: Store Deck, Slide, Block, SpeakerNote and Theme; notes are excluded from audience export unless explicitly requested and slide order is independent of block IDs.
Phase 3
Connect the working view to real saved state. Maintain one document model for preview, undo and export. Use stable element IDs; save after completed gestures, handle storage quota errors and provide explicit file backups.
Phase 4
Expose the app-specific limits and recovery path in context: Start with a small block set and local presentation mode. Remote control, live audience features and arbitrary embeds require separate security and compatibility work.
Phase 5
Walk through this concrete acceptance case and preserve its exported evidence: Add a long code block and private speaker note, then export and present on a narrow screen; flag overflow and keep the note out of the public deck. Finish the README and backup/restore instructions; report unfinished capabilities explicitly.
Build the following focused alternative to Slides.com. Implement the focused workflow below first; the verdict is not evidence of a completed or production-certified build. WORKING SLICE Create HTML-style slides from text, images and code blocks, navigate with keyboard controls and export a portable presentation. SETUP AND ARCHITECTURE Use TypeScript, React, SVG or Canvas and IndexedDB with a versioned JSON project format. Prerequisites: A browser with IndexedDB, licensed example assets and fonts, and an agreed output size. Before integrating anything, record actual versions and permissions, plus model files or provider limits only where used, in the README; make unavailable dependencies visible rather than simulating success. DOMAIN MODEL AND INVARIANTS Store Deck, Slide, Block, SpeakerNote and Theme; notes are excluded from audience export unless explicitly requested and slide order is independent of block IDs. IMPLEMENTATION CONTRACT Maintain one document model for preview, undo and export. Use stable element IDs; save after completed gestures, handle storage quota errors and provide explicit file backups. Provide an input/setup view, the main work view, and a review/export view appropriate to this workflow. Preserve the last saved state if a job or save fails. Include empty, loading, permission-denied, partial and retryable-error states. Log identifiers and error categories without secret values or unnecessary private content. APP-SPECIFIC BOUNDARY AND RECOVERY Start with a small block set and local presentation mode. Remote control, live audience features and arbitrary embeds require separate security and compatibility work. ACCEPTANCE SCENARIO Add a long code block and private speaker note, then export and present on a narrow screen; flag overflow and keep the note out of the public deck. Also reopen the app after an interrupted operation, confirm the saved record/export remains inspectable, and document the recovery action. These are implementation acceptance requirements, not a claim that this guide has been tested. DELIVERY Deliver a runnable repository with migrations or project-format versioning, a non-sensitive example, environment/permission setup, the exact manual acceptance steps, and a backup/export-and-restore walkthrough. Implement the working slice before optional integrations; list any deferred paid-product capabilities honestly. Do not add capabilities outside the working slice just to resemble the original product. PROJECT RULES FOR AGENTS.md Keep the domain invariants above executable at the write boundary. Propose scope changes before adding providers or permissions. Never fabricate source evidence, publish results, identity matches or successful delivery. Preserve user originals and require an explicit confirmation for destructive changes or external publication.

Questions about Slides.com
Can you build your own Slides.com with AI?
The verdict is yes for the scoped workflow. Slides.com's solo core is compact: build a browser-based web presentations editor with drag, resize, connect, keyboard shortcuts, autosave, and SVG or PNG export. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on interaction polish, collaboration.
What does the Slides.com build prompt cover?
The prompt starts with this scope: Create HTML-style slides from text, images and code blocks, navigate with keyboard controls and export a portable presentation. Full-product capabilities excluded from the comparison include: multiplayer cursors and comments; large template libraries; high-fidelity import and export. Follow the implementation plan and its prerequisites before expanding the build.
How do I use the prompt, AGENTS.md and agent skills?
Start with the Slides.com prerequisites and stack, then copy the prompt into your coding agent. Save the project rules as AGENTS.md in the project root. Linked skills are optional packages or source instructions for specific tasks; review their current contents and install only those matching the chosen stack. A skill does not supply API credentials or verify the finished app.
How long will this Slides.com project take?
The catalogue estimate is one sitting for the limited scope. Setup, integration approvals, debugging, deployment and ongoing maintenance can add time. This is an estimate, not a delivery guarantee.
What would I give up by replacing Slides.com?
multiplayer cursors and comments; large template libraries; high-fidelity import and export; presentation and enterprise controls. Slides.com: The shapes are easy; customers pay for low-friction editing, reliable exports, collaboration, and a canvas that never fights them.
What can I use instead of building Slides.com?
CryptPad: Collaborative browser presentations with sharing, embeds, source editing, and privacy-first storage; fewer designer templates and developer niceties. HedgeDoc: Write collaborative Markdown and present it through reveal.js, with diagrams, revisions, and exports; ideal when slides are text and code rather than decorative masonry. Check each option's license, hosting needs and feature limits.
