AI Stack: 8 AI Tools, One Unified API
We just shipped the biggest update to LiteStartup's AI capabilities: AI Stack Full Modality. Eight AI tools, one API, zero infrastructure headaches.
What's AI Stack?
AI Stack is LiteStartup's unified AI toolkit. Instead of stitching together separate APIs for transcription, image generation, video creation, and LLM routing — you get everything under one roof with consistent auth, billing, and monitoring.
The Full Tool Suite
Text & Language
| Tool | What It Does |
|---|---|
| LLM Router | Routes prompts to the best model (GPT, Claude, DeepSeek, etc.) based on task type, cost, or quality |
| AI Content Assistant | Generate marketing copy, email drafts, blog outlines directly in the dashboard |
Audio
| Tool | What It Does |
|---|---|
| Audio to Text | Transcribe meetings, interviews, and audio files to text |
| Text to Audio | Convert text to natural-sounding speech with multiple voices |
| Voice Clone | Clone any voice from a short audio sample for personalized TTS |
Visual
| Tool | What It Does |
|---|---|
| Image to Text | Extract text from images, receipts, screenshots (OCR + multimodal) |
| Text to Image | Generate images from text prompts (Seedream 3.0) |
| Text to Video | Create videos from text descriptions |
| Image to Video | Animate static images into video clips |
LLM Router: Smart Model Selection
The LLM Router deserves a special mention. It supports four routing modes:
- Auto — AI classifies your prompt and picks the best model by analyzing cost, speed, and task complexity
- Direct — You choose the exact model (Claude Opus, GPT-5, etc.) with full pricing transparency
- Tag Routes — Map tags like
fast,smart,creativeto specific models - Fallback — Chain models with automatic failover if primary is down
The router displays real-time pricing (input/output per million tokens) so you always know what you're paying.
Async by Design
Heavy tasks like video generation run asynchronously. You submit a task, get a usage_id, and poll for status. No timeouts, no broken connections on long-running jobs.
Submit → Processing → Completed → Download
Each task status includes progress updates, so your UI can show meaningful feedback.
Voice Clone: Your Voice, AI Powered
Upload a short audio sample (10–30 seconds), and AI Stack creates a voice profile. Use that cloned voice in:
- Text to Audio — Read any text in the cloned voice
Voice profiles are stored per team, reusable across all audio tools.
What's Next
We're working on:
- Weighted billing — Different AI tools have vastly different costs. Video generation will cost more credits than OCR. Fair pricing, coming soon
- Usage analytics — Per-tool usage trends, daily/weekly charts
- Task notifications — Get notified when async tasks complete instead of polling
- API documentation — Full OpenAPI spec for all AI Stack endpoints
