AI SDR tools promise to replace the grunt work of prospecting: finding leads, writing outreach, chasing replies, and booking meetings without a human rep touching a keyboard. In 2026 the category split into two camps. Fully autonomous senders like Artisan and 11x try to maximize outbound volume on their own, while augmentation platforms do the research and signal detection, then hand a rep a prepared draft to send. We dug into ten of the most talked-about AI SDR tools, their real pricing, and what they’re actually good at, so you can tell the difference between a genuine AI SDR and outreach software with a new label bolted on.
1. Artisan (Ava)
Artisan’s AI SDR, Ava, is built to own the full outbound workflow: lead sourcing, enrichment, multichannel outreach, reply handling, and meeting booking, with autonomy you can dial up or down. Contracts commonly land between $9,000 and $57,000 a year, with most customers landing in the $1,500 to $2,000 per month range. It’s one of the more complete “replace an SDR” pitches on the market, which also means you’re trusting a lot of judgment calls to the model.
Best for: teams that want one platform to run the entire top-of-funnel motion end to end.
2. 11x (Alice)
Alice is 11x’s digital worker, designed to research prospects, write personalized messages, send outreach, manage follow-ups, handle objections, and book meetings. Pricing runs $30,000 to $60,000 a year on annual contracts, or roughly $3,000 to $5,600 a month for autonomous seats, which puts it near the top of the price range in this list. It’s aimed squarely at teams trying to replace SDR headcount rather than augment existing reps.
Best for: companies scaling outbound volume without adding to the SDR org chart.
3. AiSDR
AiSDR takes your ideal customer profile and handles the rest: finding matching prospects, writing personalized emails, sending follow-ups, handling replies, and booking meetings. It’s one of the few in this list that publishes pricing openly, starting at $900 a month for the Explore plan with 1,200 AI messages and unlimited seats included. That transparency alone makes it worth a look before committing to a longer sales cycle with the enterprise players.
Best for: smaller teams that want autonomous outbound without a custom quote process.
4. Amplemarket (Duo)
Amplemarket’s Duo Copilot scored highest in one independent evaluation of eight AI sales platforms, and the broader product bundles data intelligence, email outreach, LinkedIn automation, and phone dialing into a single system. Pricing is custom and mostly on annual contracts, with most teams landing between $500 and $2,000 a month depending on seats and send volume. If you want AI-assisted multichannel outreach rather than a fully autonomous sender, this is one of the stronger options.
Best for: teams that want AI woven into an existing multichannel motion rather than a standalone bot.
5. Regie.ai
Regie.ai fits teams that already run a working SDR motion and want better content, sequencing, and signal-based prioritization rather than a full replacement. Per-seat pricing starts at $180 per user per month on annual contracts with a 10-seat minimum for the AI SEP tier, up to $499 per user per month for the Force Multiplier Rep tier with a 5-seat minimum. The full RegieOne platform is quote-only, with third parties reporting $2,000 to $6,000 a month.
Best for: RevOps teams augmenting human SDRs instead of replacing them.
6. Qualified (Piper)
Piper, now part of Salesforce, is a premium inbound specialist rather than a cold-outbound AI SDR: it works your existing website traffic, where buying intent is already real. List pricing reportedly falls between $42,000 and $68,000 a year, which puts it out of reach for most small teams. It’s a fit almost exclusively for larger orgs with meaningful inbound volume to work.
Best for: enterprise teams that want an AI layer on top of inbound pipeline, not cold outreach.
7. Clay
Clay isn’t a full AI SDR on its own; it’s an enrichment and workflow orchestration layer that you pair with a sequencer to actually send anything. Self-serve plans run $167 to $446 a month, but a complete Clay-native stack with a sequencer and data sources layered in typically runs $1,700 to $5,000 a month. Framed honestly, it’s AI SDR infrastructure, not a head-to-head competitor to the autonomous platforms above, similar to how workflow automation tools like n8n and Zapier sit underneath other go-to-market systems rather than replacing them outright.
Best for: RevOps teams building a custom outbound stack from modular pieces.
8. Apollo
Apollo has grown from a contact database into a genuine end-to-end outbound platform, and at $49 a month it’s hard to beat on price. You get a 275-million-plus contact database, email sequences, LinkedIn automation, call dialing, and AI-assisted copywriting in one place, though it’s less autonomous than the dedicated AI SDR platforms above. For teams pairing outbound with live conversations, it’s worth stacking against dedicated AI voice agents for sales calls to see where the handoff should happen.
Best for: budget-conscious teams that want data plus outreach in one tool without a six-figure contract.
9. Topo.io
Topo positions itself as a comprehensive autonomous AI SDR, managing everything from initial prospect research to qualified meeting handoff. Its agents conduct prospect research, craft personalized outreach, and manage multi-touch sequences with less manual setup than some of the bigger names. It’s newer to the space than Artisan or 11x, so reference customers and long-term deliverability track record are thinner.
Best for: teams willing to trade a longer track record for a leaner, more affordable autonomous setup.
10. Outreach.io
Outreach built its name as a sales engagement platform long before “AI SDR” was a category, and it has since layered in AI-assisted sequencing, signal-based prioritization, and generative copy tools on top of that base. It won’t run fully autonomous outbound the way Artisan or 11x will, but for teams with an established SDR team and a mature Outreach instance, the AI features act as a force multiplier rather than a replacement. Pricing is quote-based and typically scales with seats.
Best for: larger sales orgs augmenting an existing Outreach deployment rather than starting from scratch.
Which AI SDR tool should you actually buy?
If the goal is replacing SDR headcount outright, Artisan and 11x are the most complete autonomous options, though both carry real cost and real risk if the AI’s judgment on personalization or targeting is off. If you already have a working SDR motion, Regie.ai or Outreach’s AI layer will do more good than a bolt-on autonomous sender. And if budget is the constraint, AiSDR and Apollo are the two names on this list that get you into the category without a five-figure annual commitment. Whichever you pick, the honest answer is that none of these fully replace human judgment yet: they replace the repetitive 80% of prospecting so a rep can spend time on the 20% that actually needs a person.
