What AiSDR does well
AiSDR does what most of this category will not: it publishes every price and lets you start the Solo plan without a sales call. The product is broad for the money, with LinkedIn InMail, AI video and voice notes on the Scale plan, call steps through Aircall, a lead database it puts at more than 300 million, and signals from job changes, hiring and LinkedIn engagement. A native two-way HubSpot sync is on every plan.
It is a Y Combinator company from the Summer 2023 batch, says more than 250 companies use it, and reviewers praise the first-message personalisation and a dedicated go-to-market engineer during onboarding.
Where the two split: price per contact
AiSDR's Solo plan works out at $1.25 per AI-researched contact, Explore at about $1.13 and Scale at $1.00. BOSRAI's Agent plan works out at about $0.07 per verified contact and Growth at $0.04. That gap is large enough to matter, but the units are not identical: AiSDR's contact includes research work that BOSRAI does as part of writing each message. The number that decides it is cost per meeting on your own audience, which only a trial will tell you.
Where the two split: commitment
AiSDR's Solo plan is monthly and cancellable. Explore and Scale are quarterly contracts paid in advance. Reviewers name the quarterly commitment and the lack of a free trial among their main complaints. Every BOSRAI plan is monthly, and there is a free plan with 250 verified contacts a month.
Where the two split: channels and disclosure
AiSDR covers email, LinkedIn and phone steps, and adds video and voice notes at the top tier. We found no WhatsApp. BOSRAI adds WhatsApp, used only after a person has engaged, which is the channel that carries replies in the Gulf, Turkey and much of South Asia.
BOSRAI adds an AI disclosure line to messages sent without a person approving them, as the EU AI Act asks since August 2026. We found no disclosure statement on AiSDR's site. AiSDR's own buyer guide says customer campaign data is used to improve its models; read its terms if that matters to you.
Who should pick AiSDR
A team that sells on LinkedIn and email, wants InMail, video or voice notes, lives in HubSpot or Salesforce, and is comfortable with a quarterly commitment once past the Solo plan.
Who should pick BOSRAI
A founder or small team that wants more contacts for less money on monthly terms, needs WhatsApp, and wants every message approved until each channel has earned autopilot.

Questions people ask
Is BOSRAI an AiSDR alternative?
Yes. Both are self-serve AI SDRs with published prices, buying signals, reply handling, and a choice between approving messages and running on autopilot. They differ on price per contact, contract terms, WhatsApp and the AI disclosure.
How much does AiSDR cost?
On 14 September 2026 AiSDR's pricing page listed Solo at $250 a month for 200 AI-researched contacts, Explore at $900 for 800 and Scale at $2,500 for 2,500. Solo is monthly; Explore and Scale are quarterly contracts. Annual billing takes 20 percent off.
Does AiSDR send on WhatsApp?
We found no WhatsApp on AiSDR's homepage or pricing page. It sends email through Gmail or Outlook, works LinkedIn connection requests, messages and InMail, and adds call steps through the Aircall dialer. BOSRAI sends email, LinkedIn and WhatsApp in one sequence.
Do both integrate with HubSpot?
Yes. AiSDR lists a native two-way HubSpot sync on all plans and Salesforce on Scale. BOSRAI writes contacts, deals and booked meetings back to HubSpot.
Is a contact the same thing in both tools?
Not exactly. AiSDR counts AI-researched contacts, which include research work per person. BOSRAI counts verified contacts found for your audience. Compare the cost per meeting in a trial rather than the cost per contact on paper.
