One-time setup needed

fibula needs your Anthropic API key. Open your terminal and run:

setx ANTHROPIC_API_KEY "sk-ant-your-key-here"

Get a key at platform.claude.com → Settings → API keys. After running the command, close the terminal, restart fibula (start.bat), then check again.

fibula needs ffmpeg to cut video. Open your terminal and run:

winget install ffmpeg

When it finishes, restart fibula (start.bat), then check again.

What are we clipping today?

Drop a link or a video file — fibula finds the moments and writes the post.

No idea what to clip? — or skip the pasting entirely and .

How fibula decides what makes the cut — pick the one that sounds like your account.
Up to 20 per run — fibula ranks them, you keep the best.
Captions 31 styles, playing live — scroll for more
Caption size
How big the captions burn onto the clip, previewed at true relative scale. Medium fits most 9:16 clips; Large reads best on fast, punchy cuts; Small stays out of the way on 16:9.
Tighten clips
Removes the parts nobody watches. Fillers cuts ums, stutters and dead air using the word timestamps. Smart also has the AI mark boring-but-on-topic stretches — wind-ups, restatements, weak asides. Every cut is listed in the editor with its reason; untick any before export.
AI B-roll
Licensed stock cutaways matched to what's being said — fibula reads the transcript, finds the visual nouns and covers them with footage, timed and placed automatically. Accept, swap or delete each one in the editor.
Most-replayed first
YouTube publishes which parts of a video viewers rewatch most. On = curation starts from those replay peaks, so your clips come from moments with proven pull. Tune how hard it leans under advanced.
Brand kit
Your logo, handle, fonts and colours applied to every clip at render — one preset per channel you run. Your branding, never a forced watermark.
Who is featured — names the copy correctly.
What KIND of video this is — adds format context under any Clip style (the style is your account's voice; the genre is the source's shape).
Cut mode
Precise is frame-accurate (GPU). Fast snaps to keyframes.
How hard curation leans toward the parts viewers rewatched on YouTube. Off ignores the replay data entirely, Light nudges the picks toward peaks, Balanced weighs them equally with the transcript, Strong makes replayed sections dominate — best for very long episodes.
Breathing room added before each clip's first word, so it doesn't start mid-breath or clip the first syllable. 0.4s fits most speech; raise it for slow, deliberate talkers.
Room added after the last word, so the clip lands instead of cutting off hard. 0.75s lets a punchline breathe; shorten it for rapid-fire content.

Direct per-platform connections roll out as their app reviews clear.

API access

      
fibula runs on the same REST API you can call yourself — submit jobs, pull clips, run Autopilot. The MCP server exposes 15 tools to Claude and any agent, and tools/fib.py is the CLI. Keys below carry a daily budget; full docs at /p/api.

  • No bidding on "fibula" brand keywords in ads.
    • 
        
  • No self-referrals or bulk fake accounts — both void the balance.
    • 
        
  • Disclose the affiliation where the law requires it (FTC etc.).
    • 
        
  • Commissions pause if the referred account refunds or charges back.

Let's build your clipping style

    
Answer in plain words. fibula writes the curation prompt the way the
    top clipping accounts would — concrete shapes, clear boundaries, a real
    scoring bar — and it lands in your presets.

    

      
      
    

    

      
      
    

    

      
      
    

    

      

        

      

        

    

    

      

        
        
      

      

        
        
      

    

    

      
      
      
    

  






  

    
Watch a channel

    
Every new upload gets clipped with these settings and its best clips
    land on your calendar. A fresh watcher arms on the channel's current
    newest video and starts clipping from the next upload — it never
    burns minutes on back-catalog.

    

      
      
      
That's the only required step — style, captions, platforms
      and quality are pre-tuned. Open Customize to change them.

Edit the prompt and run curation and cutting again — no re-download,
    no re-transcription. The original run stays in your Library.
