AI document conversion for math, chemistry, tables and full PDFs
Recognises printed and handwritten math, chemistry diagrams, tables and text across many languages and returns editable output such as LaTeX, Markdown, MathML, SMILES or ChemDraw.
Screenshot any region of your screen or a web page and copy the converted math, chemistry or text straight to your clipboard with a keyboard shortcut.
The OCR API and Files API let you embed the same conversion engine in your own product, with support for Python and CLI workflows and full PDF document processing.
Convert PDFs to LaTeX, Word, Excel, Markdown, HTML or Overleaf-ready output, and images to LaTeX, AsciiMath, CSV or other structured formats.

Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.

Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.


Free / Open-sourceAlibaba Cloud's 4th-generation multimodal AI assistant and foundation model lineup (Qwen4-Max, Qwen4-Plus, Qwen4-Flash & open-weight Qwen4-27B) with 1M context.

Unifies hundreds of third-party models under a single API key, offering greater model choice than OpenAI's curated catalog.

Provides developer APIs for Zhipu AI's proprietary GLM models, serving as an alternative enterprise foundation model stack.

SpecialistOptimized for lightning-fast serverless execution of generative media and image models, rather than general text LLMs.
Free desktop and web PDF utility with AI features, but offers weaker mathematical symbol and LaTeX conversion.

Provides versatile PDF editing and conversion tools, but lacks Mathpix's deep scientific equation and chemistry recognition.

Specializes in high-performance serverless inference and dedicated GPU clusters for open-source models, bypassing closed commercial restrictions.
SpecialistProvides interactive document Q&A and summary features, but lacks advanced LaTeX export and math OCR capabilities.

SpecialistFocuses heavily on running and fine-tuning open-source vision and language models via simple APIs, unlike OpenAI's hosted closed models.
One OpenAI-compatible API for 500+ image, video, audio, and LLM models

SpecialistDelivers ultra-low-cost serverless inference for open-weight models, though with fewer enterprise orchestration tools than OpenAI.
