Local-first visual note-taking on an infinite canvas
Flexnote is a local-first visual note-taking app for deep learning and research. Capture ideas as cards, arrange them on an infinite canvas, and connect them with mind maps and bidirectional links. Annotate PDFs and YouTube videos, then use Flexnote AI to search, summarize, and organize your own knowledge base. Notes stay on your device by default, with optional sync through OneDrive, S3, or WebDAV. Free to start on Windows, macOS, and Android.

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.
