AiSDR
Stands out: A public $1.50 per person pay-as-you-go plan with HubSpot, Salesforce, Close, Clay and Calendly named, and cancel-anytime terms.
Watch out: Team plans for 1,000+ people a month are priced on volume through sales. No free trial is named. Per-campaign managed service is extra.
Not the right fit for
Twain
Stands out: Twain cites dated, linked sources for every signal it uses, so you can check why it wrote what it wrote, which a first line tool like Lyne.ai does not show. It prices by credits with unlimited team members and ships its own MCP server, so a whole desk can share one pool and run it from Claude.
Watch out: Exporting researched data to your CRM or files needs Pro at $198 a month, so Starter is mainly for working inside Twain or a connected sequencer. Ultra mode starts at 10 credits per lead, so deep research burns through a 500 credit plan quickly.
