Why choose Phersa
What you get in Phersa, whichever tool you compare it with.
-
Start from what already worked
The video library holds viral organic Instagram and Facebook videos, with new ones added every day. You pick a video that performed instead of guessing what to make.
How the video library works -
See the script, not only the clip
Every video comes with its stats, every word spoken and a shot-by-shot breakdown: the hook, the structure and the call to action. Search by what is said, and open similar videos from any one.
What a video shows -
Follow the accounts in your niche
Add any TikTok, Instagram or Facebook account and its new videos arrive every day. Save a single video by link or upload and it is transcribed and broken down the same way.
How tracking works -
Your AI agent can run it
Claude, ChatGPT, Cursor and other agents get 40 tools over MCP: search the library, plan the clips with your persona, edit and export. Nothing is generated until you confirm the cost.
Connect your agent -
One price, your own keys
$99 a month, one plan. Generation runs on your own keys across 9 providers at their published prices, so you switch models as they change. New Google Cloud customers get $300 in free Google credit.
How keys work -
Comment-to-DM monetization
When someone comments your keyword on Instagram or Facebook, Phersa sends them the DM and can reply to the comment. The plan covers 2 accounts and 25,000 DMs a month.
How comment-to-DM works
From Fastlane to Phersa in four steps
- Connect an API key Add an image and video API provider’s key in the app (ElevenLabs adds voice). Generation is billed there, at its published price.
- Create your AI persona Upload one reference image; it is your AI persona in every video. Add an ElevenLabs voice if you want one.
- Start from a viral video Pick one from the video library and study it shot by shot, or track accounts and save videos of your own.
- Make it, by hand or with your agent Make the clips and edit the video in the app, or connect your AI agent over MCP and let it plan them.
One plan. Everything in it.
Your own keys pay for generation, at the provider’s price. The plan covers the rest.
