Free in-browser analyzer for grammar, readability, tone and SEO
Detects errors, awkward phrasing and style issues with suggestions driven by the open-source LanguageTool engine.
Flesch Reading Ease, Flesch-Kincaid, SMOG, Coleman-Liau and Dale-Chall are calculated together and shown with grade-level interpretation.
Flags whether text reads as academic, professional or casual, and reports the emotional sentiment so you can match your audience.
Weighs keyword density, content length, semantic completeness and readability against SERP averages for your target query.
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.
