9 Best AI SDR Tools of 2026

Apollo.io is the broadest pick for a team that wants AI to help with every outbound step without hiring a separate agent vendor. The plan comparison lists AI Research, AI Filter, AI Scores and Agents next to the contact database, so reps can find accounts, have AI research them and draft copy in one place. Basic costs $49 per seat per month billed annually and grants 30,000 credits per seat per year up front, unlimited sequences, 250,000 AI Writing words per month, the deliverability suite with warmup and a US dialer. Professional at $79 adds A/Z testing, AI lead scoring and 4,000 minutes of call recordings with AI insights. The trade-off is that Apollo is a copilot for reps rather than a fully autonomous SDR: someone still owns the sequences and replies. Credits also cover both data and dialing, so heavy callers should model usage. For most small and midsize teams it is the lowest-risk way to add AI to outbound.

Unify is built around a chat box: a rep describes the buyers they want, and Unify builds the list, researches the accounts and writes the sequence. Its pricing page says sellers from Perplexity, Juicebox and Pylon use it to build lists and write sequences 90% faster, which is the vendor's own claim. The free plan includes the 1.1B+ person database, multi-channel sequencing and a click-to-call dialer for up to 3 seats. Base at $20 per seat per month adds AI email copywriting, job change and hiring signals and phone and email enrichment, with 800 credits per seat. Pro at $60 adds read-only HubSpot and Salesforce sync, Slack notifications and 2,400 credits. Credits fund both data and AI, and Unify enforces a hard cap so actions pause instead of overcharging. The limits show up for larger teams: write-back to the CRM, the power dialer, managed mailboxes and website intent all sit in the custom-priced Business plan.

RegieGO is Regie.ai's self-serve product for reps who fill their own pipeline. You describe your ideal customer, it builds the list, runs waterfall enrichment for emails and phones, researches each account for dated why-now signals and drafts messages in your voice. Emails go out from your own Gmail or Outlook, and Regie says every contact is verified before send and sending is throttled. Pro costs $41 a month billed annually or $49 monthly and includes 5,000 credits a month plus the parallel dialer, which dials up to five lines at once. Team is $125 per seat billed annually with a two-seat minimum and a shared credit pool. A free CRM comes with every plan, or you can sync HubSpot or Salesforce. The limits are in the credit rules: paid credits reset each period, and you cannot buy extra credits separately. It is a copilot that keeps the rep in control rather than an autonomous agent.

AiSDR is the clearest example on this list of an AI SDR that does the work rather than assisting a rep. Its agent, Ami, which AiSDR says was trained on 18K campaigns across 27 industries, builds a campaign from your website, picks prospects from 2B+ profiles, writes email and LinkedIn messages, classifies replies and answers in 5 to 10 minutes or in co-pilot mode. Pricing is the easiest to test: $1.50 per person prospected, charged daily, with no subscription and campaigns starting from $7.50. Research, lists and writing are included in that fee. Teams contacting 1,000+ people a month can move to a volume plan with up to 40% lower cost per contact, a dedicated GTM engineer, Salesforce integration and website visitor tracking. The catch is that cost grows with reach, and buyers who want the agent tightly controlled should start in co-pilot mode before letting it reply alone.

Amplemarket packages data, AI and execution for teams that want to retire a separate database and sequencer. Its Duo AI layer includes Copilot for daily prioritization, Copywriter for personalized first touches, intent signals, Voice for AI voice messages and Inbox for draft replies to prospect emails. The Startup plan costs $600 per month on an annual term, includes 2 users and 27,000 contacts, and lists Duo Copilot and AI intent signals. Growth adds Duo Voice and a dedicated CSM, and Elite adds Duo Inbox and 400,000 contacts, both at custom prices. Deliverability tools such as the Domain Health Center and warmup are built in, and an add-on exposes Amplemarket to Claude or ChatGPT through MCP. The price floor is the obstacle: a solo seller pays far less elsewhere, and the AI reply drafting that brings it closest to an AI SDR sits on the top tier.

Clay is the research and personalization engine many outbound teams put underneath their sequencer. Each row in a Clay table can pull from multi-provider waterfalls and run Claygent, Clay's AI agent with web research, to produce custom data points such as a recent initiative or a tech stack detail that then feeds an AI-written opening line. Clay Sequencer sends email natively, or results push to other campaign tools. The free plan includes unlimited seats, Claygent and up to 200 rows per table. Launch costs $167 per month billed annually, or $185 monthly, with 2,500 data credits and 15,000 actions a month, phone enrichment and signal tracking. Growth adds CRM auto-sync and HTTP API integrations. The cost of that flexibility is setup time: Clay rewards someone who can design workflows and prompts, and a rep who wants a ready agent will move faster with AiSDR or Unify.

11x sells AI sales agents rather than a seat-based tool. Its site describes an outbound agent for prospecting, email and social, and an inbound agent that qualifies leads over voice and chat, with the claim that every inbound lead is answered in under a minute. The platform lists a real-time company and lead database, live web search for prospecting, multi-channel and multi-lingual sequences, smart replies, deep research, AI personalization, website visitor tracking, intelligent lead routing and an AI phone agent, with CRM, Slack and G2 integrations and an API. That breadth suits revenue teams that want one vendor for speed to lead, outbound and expansion plays such as closed-lost and customer expansion campaigns. The downside for buyers comparing prices is that 11x publishes none: there is no pricing page, and access starts with a demo. Smaller teams that want to start this week will move faster with a self-serve product.

Artisan sells Ava, an AI BDR that books meetings for reps. Ava identifies prospects from 250M+ verified B2B contacts, runs email and social campaigns with calls queued, replies on its own and books meetings. Campaign types cover cold outbound, intent signals, re-engaging existing and churned CRM contacts, and cross-sell. Plans are sized by volume: Team is scoped for roughly 2,500 leads contacted a month, Scale for roughly 6,000 with a dedicated CSM and CRM setup, and Enterprise adds a forward-deployed strategist and advanced security controls. Every plan includes Salesforce and HubSpot sync and CSM onboarding, and an AI dialer is a per-seat add-on. Artisan positions this as a white-glove rollout with sending infrastructure sized to your motion. The trade-off is transparency: the pricing page says pricing is scoped on your plan, so you cannot compare costs without a sales call.

Outreach is the incumbent sales engagement platform, now positioned as an AI agent platform for revenue teams. Pricing combines per-seat access with consumption-based AI credits that fund research, personalization, sequencing automation, conversation analysis and forecasting. Amplify Core, aimed at pipeline creation and account management, includes 25,000 AI credits with sequencing, account planning and conversation intelligence. Amplify Plus adds advanced agents, coaching and deal management with 50,000 credits, and Amplify Pro adds forecasting with 100,000 credits. For an enterprise org that already runs Outreach sequences, adding its agents keeps everything on one system of record. For a team shopping specifically for an AI SDR, it is a lot of platform: every package is quoted by sales, and the credit model makes total cost harder to predict than per-person or per-seat tools.
