The best AI SDR tool depends on how much you let the AI send by itself. AiSDR, Artisan, Gojiberry, 11x and Reply.io's Jason run outbound for you, with approval modes you can switch on. Amplemarket and OXYGEN keep a person in the loop: OXYGEN's Copilot drafts and runs the work and asks before it sends, next to sequences, lead data and a CRM, from $49 a month.

An AI SDR tool does parts of a sales development rep's job: it finds leads that fit your profile, researches them, writes outreach, follows up and sorts the replies, and some book meetings. The tools below differ in six ways: how you pay, how much they send without a person approving, which channels they use, where the contact data and buying signals come from, whether a CRM is included, and whether your own AI agent can drive them through MCP or an API. Approval is where they differ most: some can send on Autopilot, others wait for a rep to send each draft.

OXYGEN Agentic marketing and sales platformBest for: B2B teams that want AI to draft and run outbound while a person approves the sends, with sequences, lead data and a CRM in one workspace.
OXYGEN pairs AI that drafts with the tools that run outbound. A Copilot in the web app builds lists, writes sequences and runs the work, and asks before sends and larger paid steps unless you turn on Auto-approve. AI columns research and write over your rows, a research agent cites its sources, and replies land in one inbox with AI triage and drafted answers. Free LinkedIn signals such as profile viewers and post reactions can start a workflow or enroll a lead. Your own AI agent, such as Claude Code, Codex or Claude, can run it through the MCP server or the CLI.
AiSDR Pay-per-contact AI SDRBest for: Teams that want an AI SDR to run email and LinkedIn outbound for them and pay only for the people it contacts.
AiSDR's agent, Ami, plans, launches and tunes campaigns from a chat, researches each lead, and writes and answers the messages. It runs email, LinkedIn and Aircall call steps in one sequence, finds people by job changes, new hires and funding, and pulls contact data from a 20-provider waterfall, all inside $1.50 per person contacted. The first campaign waits for approval, and co-pilot mode holds replies for review. It is not a CRM: contacts sync both ways with HubSpot, and with Salesforce on team plans. It has no public API or MCP server.
Artisan AI BDR with a contact databaseBest for: Email-first teams that want an AI BDR, a contact database and buying signals on one credit plan.
Artisan's AI BDR, Ava, runs campaigns from a 250M+ B2B contact database, finds emails and phones through a waterfall of 22+ sources, and watches 14 signal types, from funding and hiring to website visitors. A sequence holds email, task and human call steps, with a power dialer at $75 a seat a month; no LinkedIn steps are documented. Messages can wait for approval. Seats are free and you pay in credits per workspace, with a Free plan for search and a 30-day trial. It syncs both ways with HubSpot or Salesforce and has an early MCP connector for Claude.
Gojiberry Signal-led AI agents for LinkedIn and emailBest for: Founders and small teams that want AI agents to work LinkedIn and email signals at a low monthly price.
Gojiberry's AI agents track signals such as engagement on competitor and expert posts, keywords, profile visitors, job changes, funding and hiring, then contact the matches on a schedule.

Emails come from a waterfall across 15+ providers on monthly credits, and Review Mode holds leads for approval. Pro is $99 a month per user with 2 agents and 2 LinkedIn seats, an MCP server and a public API. It is not a CRM: it pushes contacts to HubSpot, Salesforce, Pipedrive and Attio.

An AI SDR is software that does parts of a sales development rep's job: it finds people who fit your profile, researches them, writes the first message and the follow-ups, and sorts or answers the replies. Some, such as 11x's Alice and Reply.io's Jason, also book meetings. The tools differ most in how much they send without a person approving it.
They can, but no vendor's reply rate tells you what yours will be. Results depend on the list, the offer, the copy and whether your mailboxes land in the inbox, and we did not test reply rates for this list. Start with a small segment in an approval mode, read what the AI drafts, and compare replies and meetings with what your team gets today before you scale up.
AiSDR charges $1.50 per person contacted with no monthly fee. Gojiberry Pro is $99 a month per user, Artisan's Intern plan $280 a month ($250 billed yearly), Reply.io's Jason from $500 a month billed yearly, and Amplemarket's Startup plan $600 a month billed yearly for 2 users. 11x quotes an annual contract after a demo. OXYGEN starts at $49 a month per workspace, plus $34 a month for each LinkedIn account you connect.
An AI SDR covers research, first drafts, follow-ups and reply sorting across many leads at once. A person is still better at discovery calls, objections and accounts where judgment matters, and someone has to own the list, the offer and the voice either way. Many teams start by giving one rep a tool that drafts and queues the work, then decide how much to let it send by itself.
On every tool here. 11x lets you review every message, use an approval workflow or run Autopilot, per segment. Reply.io's Jason has an Approval mode, AiSDR holds the first campaign and co-pilot replies, Artisan can hold messages and Gojiberry's Review Mode holds leads. Amplemarket's Duo drafts and reps send. OXYGEN's Copilot asks before sends and larger paid steps unless you turn on Auto-approve. Approval is the main guard against off-brand copy.
OXYGEN runs LinkedIn in the cloud with no browser extension: visits, invites, messages, InMail, follows, likes and comments. AiSDR and Gojiberry run LinkedIn steps in the cloud on your account, Amplemarket's blog says its LinkedIn actions run on the server side, and Reply.io's Jason sends connection requests, messages and AI voice notes. 11x lists LinkedIn as a channel without saying how it runs, and Artisan documents no LinkedIn steps.
Mostly not. 11x, Amplemarket and Reply.io sync both ways with Salesforce and HubSpot, AiSDR syncs with HubSpot and with Salesforce on team plans, and Gojiberry pushes new contacts out. Artisan keeps people, companies and deals synced in from your CRM. OXYGEN includes a CRM with a deals pipeline on every plan and syncs both ways with HubSpot; it has no Salesforce sync, so a Salesforce team keeps Salesforce.
