Connect SendShort once and any assistant — Claude, Cursor, OpenClaw, Hermes, ChatGPT — can import a YouTube link, cut the best moments, caption them and hand back post-ready shorts.
Terminal
# Add the SendShort connector
npx sendshort-agent connect
# Set your API key
export SENDSHORT_API_KEY=ss_live_•••••
# Check the assistant can see it
sendshort tools:list
# Make your first shorts
sendshort clips:create \
--source "https://youtu.be/xxxxxxxx" \
--clips 5 --ratio 9:16 --captions
Built for automation
Every tool returns structured JSON, so Claude, Cursor or ChatGPT can plan, call and verify a render on its own.
Point it at a YouTube URL or a file and it scores retention, cuts the moments and reframes to 9:16.
Word-level captions at 98%+ accuracy, brand-kit styling, automatic B-roll and zooms on every clip.
One connector, any assistant. Claude, Cursor, OpenClaw, Hermes, ChatGPT and Codex are all tested.
Give the agent a cron heartbeat and it clips new episodes the morning they land — no prompt needed.
The agent calls the exact endpoints your backend can call. No second pipeline, no drift in output.
The agent lists your brand kits, caption templates and connected destinations before it touches a video.
Discovery

# Inspect a brand kit

One call imports the source, finds the strongest moments, burns captions and renders every ratio you asked for.
Clip creation
sendshort clips:create \
--source "https://youtu.be/xxxxxxxx" \
--clips 5 \
--ratio 9:16,1:1,16:9 \

Chat-app driven workflows
Runs local, posts on a schedule
Raw → post-ready
Same footage, reframed to 9:16, cut to the moment that holds attention, captioned word by word and styled to your brand kit — no timeline, no export settings.
Every tool call returns structured JSON your agent can parse
A bundled SKILL.md documents every command and argument
Discovery lets the agent read brand kits before rendering
Long jobs are async with webhooks — no timeouts mid-render
Model agnostic: Claude, GPT, Gemini or open-source LLMs
Human in the loop by default — nothing publishes without you
