Companies+ New Company⋮
Find the companies that fit you, straight from the live web, with one plain-English prompt.
Search the live web
Add a Firecrawl, Tavily, Brave or SerpApi key and OS20 reads real company websites, not a database that went stale last year.
Only real company websites
Search results are full of directories, "top 10" articles and duplicates. OS20 drops those first, then reads each company's own site.

Talk to your CRM
Ask AI works with the same records you see. Find leads, look up a company or create records by asking in plain words.
Triggers and actions
Start a workflow when a record changes, on a schedule, from a webhook or by hand. Then create or update records, send email, call an API or run code.
Local models with Ollama
No API key at all? Run Ollama on the same machine and OS20 picks it up. Your prompts and records stay on your computer.

Why I built it
I wanted a CRM that finds leads for me, runs on my own laptop and doesn’t charge a monthly fee to hold my own data. I couldn’t find one that did all three, so I built it.
What it does
You ask for leads in plain words. It searches the web, reads each company’s site, scores the fit and saves the good ones to your CRM, with real contacts and a first email ready to edit.
