10 Best AI SDR Tools of 2026

AiSDR is the most direct way to try an AI SDR without committing to a contract. The pay-as-you-go plan costs $1.50 for each person prospected, is charged daily and can be stopped at any time, and research, list building and message writing carry no extra fee. Its agent, Ami, is trained on 18K campaigns across 27 industries according to the vendor, and it builds a campaign, runs it and adjusts it as replies come in. Prospects come from 2B+ profiles with live signals for job changes, hiring and funding, enriched through a waterfall of 20 data providers. Sequences combine email with LinkedIn connection requests, DMs, InMails and voice notes, and the platform handles bounce checks, lookalike domains and warmup. Replies land in one inbox where AI classifies and answers them, and HubSpot syncs both ways. Teams contacting 1,000+ people a month move to volume plans with up to 40% lower cost per contact, a GTM engineer and Salesforce, but those prices are quote-only.

Reply.io offers two ways in. Human-run outreach starts with the Email Volume plan from $49 per user per month on annual billing, or the Multichannel plan from $89 that bundles email, LinkedIn, calls, SMS and semi-automated WhatsApp. The AI route is Jason AI SDR, listed from $500 a month, which the vendor describes as one fully automated solution with 24/7 operation, real-time contact search, intent signals, AI personalization and AI-generated responses to replies. Because Jason runs inside Reply's sequencing platform, teams get the same deliverability tools, warmup, reporting and integrations with Salesforce, HubSpot and Pipedrive. The contact search covers 1+ billion B2B contacts. The trade-off is that the costs stack: LinkedIn and calling are add-ons on the cheaper plan, and Jason AI is a separate line from user seats. For teams already running sequences, that layering is a strength because the AI SDR and human reps share one system.

Unify is built for a rep who wants AI-assisted outbound without a procurement process. The Free plan includes AI outbound, multi-channel sequencing, a click-to-call dialer and access to 1.1B+ people and 65M+ companies from 40+ data sources for up to 3 seats. Base costs $20 per seat per month on monthly billing with 800 credits and adds AI email copywriting, job change and hiring signals, and phone and email enrichment. Pro at $60 per seat adds 2,400 credits, read-only HubSpot and Salesforce sync and Slack notifications, with a 14-day trial that needs no card. Signals cover tech stack, new hires, funding, paid ad activity and SEO and AI search visibility. The fuller AI SDR setup, with website intent, signal-triggered automations, managed mailboxes, a power dialer and read-write CRM sync, sits on the custom Business plan. Unify is less autonomous than a dedicated agent like AiSDR, but it is the cheapest way here to put AI to work on prospecting.

lemlist has moved from a cold email tool to a multichannel platform with AI agents built in. The Email plan is $55 a month on yearly billing, or $69 monthly, and covers unlimited users and email senders, 50,000 emails a month, the 650M+ lead database, email and phone finders, lemAgent signal, enrichment and messaging agents, the lemlist MCP and CLI, warm-up and CRM integrations. Multichannel, from $87 a month on yearly billing, adds five senders per user, LinkedIn automation, SMS, a WhatsApp add-on and a built-in dialer. The AI layer covers account and contact research, intent signal agents, URL scraping, AI reply intent detection, AI-generated replies, personalized LinkedIn voice notes and CRM auto-fill. Extra data costs more: enrichment starts at $16 a month and buying intent signals at $21. lemlist works best for teams that want AI help inside sequences they still control, rather than an agent that runs outbound end to end.

RegieGO is Regie.ai's self-serve product for people who fill their own pipeline. The Free plan gives each person 250 one-time credits, shared across up to 10 people, with research, enrichment, drafting and agents, plus a free built-in CRM and sending from your own Gmail or Outlook. Pro costs $49 a month, or $41 a month on annual billing, and includes 5,000 credits a month, the parallel dialer with local numbers you choose, and a rule that enrichment costs nothing when it finds nothing. Team runs $150 per seat monthly or $125 annually, with 15,000 credits per seat in one shared pool and a two-seat minimum. HubSpot and Salesforce connect on any plan, with optional write-back. RegieGO keeps a rep in the loop more than the autonomous agents here, so it suits people who want AI to research and draft while they send and dial. Enterprise adds volume credits, custom CRM sync and SOC 2 security.

Agent Frank is Salesforge's AI SDR, and it is priced by active contacts rather than seats: the entry tier is $499 a month on annual billing for 1,000 active contacts, and volume above 2,000 contacts works out to $0.25 per contact. Frank researches each prospect, company, buying signals and likely objections before writing, then follows up and books meetings, in auto-pilot or co-pilot mode and in 20+ languages. Your feedback shapes the memories it uses for later outreach. It runs on the Forge Stack, so leads can come from Leadsforge, infrastructure from Infraforge or Megaforge, and warm-up from Warmforge, with work managed in Salesforge. Every customer gets a dedicated account manager and shared Slack channel. Setup is slower than a self-serve tool: Frank is only available after a demo, and new mailboxes need about two weeks of warm-up. Salesforge is unusually clear about fit, pointing to B2B deals of $5K to $100K and away from Fortune 500 targets.

Amplemarket sells one platform meant to replace a stack of data, engagement and AI tools. The Startup plan costs $600 a month on an annual term and includes 2 users, 27,000 contacts, multichannel sequences, AI intent signals and the Duo Copilot, with scaled CSM support and community onboarding. Growth adds 4 users, 140,000 contacts, a dedicated CSM and Duo Voice for AI voice messages, and Elite adds 10 users, 400,000 contacts and Duo Inbox, which drafts a reply to every prospect email. The data side covers contact and company search, 200M real-time verified mobile numbers, enrichment, email validation and job change alerts. Deliverability tools include a domain health center, warm-up and a spam checker, and an MCP add-on lets reps prospect from Claude or ChatGPT. The cost and annual term make it heavier than the self-serve tools here, and the most autonomous features sit on custom-priced tiers.

Artisan's Ava is one of the best-known AI BDRs, and the product is sold as a managed rollout rather than a self-serve tool. Ava finds leads from 250M+ verified B2B contacts, writes outreach, handles replies and books meetings, sending in your reps' names from your own domains. Controls include approval before sending, locked tone and calls to action, banned phrases and coaching on Ava's writing. Plans are sized by volume: Team covers about 2,500 leads contacted a month and Scale about 6,000, with Scale adding a dedicated CSM, CRM setup and priority support, and Enterprise adding a forward-deployed strategist. Salesforce and HubSpot sync both ways, webhooks bring in your own data, and an AI dialer add-on gives reps a brief before each call and a follow-up after. Artisan is SOC 2 Type II certified with SSO and audit logs. Prices are scoped on a sales call, so cost comparison requires a demo.

11x has broadened from an AI SDR into a platform of revenue agents that work across voice, chat, email, social, SMS and WhatsApp. On the inbound side, voice and chat agents contact form fills in under 60 seconds, qualify fit, needs and timeline, and book a meeting with the right rep using your routing rules, around the clock and in multiple languages. Outbound agents act on live signals, re-engage inactive or closed-lost leads, de-anonymize website visitors, research each prospect with CRM context and coordinate email, social and dials in one sequence, with deliverability managed in house. Expansion agents call existing customers, uncover needs, close simple upgrades or hand off to a live rep. That scope is the widest on this list. The drawback is transparency: 11x publishes no prices and no integration list on its main site, and buying starts with a demo, so small teams will find self-serve options faster to test.

Qualified's Piper is an AI SDR aimed at inbound demand. It talks with website visitors by text, voice and video, runs email conversations with known contacts, qualifies them and books meetings, with multi-language support. The Premier plan includes one SDR agent profile, 250K monthly web sessions and 2.5K monthly active email contacts. Enterprise raises capacity to 2M sessions and 10K email contacts and adds agent handoff, MCP and API access and a Salesforce sandbox, while Ultimate adds multiple agent profiles, high-volume contact databases and a dedicated IP. Every plan includes Agent Studio, account segmentation with waterfall enrichment, Salesforce integration plus 20+ go-to-market systems, and conversation, email and meeting routing. Qualified says Piper has been hired by over 500 companies. The product fits marketing teams with steady website traffic and a Salesforce stack. It is not a cold outbound tool, and pricing is only available through a demo.
