SlideFast?

KINDAYou can build the valuable core, but the established product has meaningful operational complexity. Pick one narrow promise for v1.

BUILD FIRST

One specific customer type and one primary use case
A vertical slice that completes the main job without manual workarounds
Visible limits, review steps, and a fallback when an external dependency fails

LEAVE FOR LATER

Broad third-party integrations
High-scale collaboration, syncing, and permissions
Automation that can cause harm without human review

RESEARCH NOTES

What this tool actually does.

Checked 2026-09-06

SlideFast is a web-based AI carousel generator aimed at freelancers and agencies creating social media carousels. Users input a one-line brief, URL, client notes, or an existing post; the tool determines an angle, writes copy, and lays out slides with hook, slides, CTA, and caption. It supports per-client projects and shareable review links for client approval, then publishes to LinkedIn, TikTok, Instagram, or Facebook Pages, or exports PDF/PNG. An MCP server/CLI wraps its API for programmatic creation, editing, export, and asynchronous publishing, with TikTok draft mode. It is a subscription service starting around $19/month, requiring Google sign-in and users 18+.

RESEARCHED BUILD PROMPT

Give this to your coding agent.

Build a focused replacement for the core SlideFast workflow: a web app where a user pastes a rough brief (topic, URL, notes, or existing post) and selects a target platform; an AI layer proposes a carousel angle, generates slide copy (hook, body slides, CTA) and suggests a visual layout; the user can edit any slide's text, reorder/delete/add slides, and set simple style variables (colors, font family, logo). Each carousel belongs to a client project. The user can generate an anonymous client review link (no login required for the reviewer) that shows the final carousel and allows approve/request-changes comments. After approval, the app publishes the carousel to LinkedIn (live), TikTok (draft by default), Instagram/Facebook Page (live), and supports PDF and per-slide PNG export. Implement with a React SPA, Node/Express backend, and a relational store (Postgres/SQLite); use an LLM provider for copy generation and the platform's official APIs for publishing with an async status-polling model. Do not copy SlideFast's brand name, logo, templates, or exact UI. Out of scope: billing/subscriptions, advanced brand kits, multi-user teams, analytics, and a mobile app. Include a README with setup instructions, required API keys, publishing rate limits, and the limitation that LinkedIn/Instagram have no draft mode, while TikTok drafts require manual posting from the app.
