Shortlist
Closest alternatives to Aissist.io
The ones people open most here come first, then the closest matches. How we rank
- 01
VeraDialVerified
AI receptionist and verified US/Canadian business line that answers calls and texts and places outbound calls.
From $14.99/monthWhy it's on this listSeat model · YesSeats are not charged for but they are capped: the owner plus one teammate on Plus and up to three on Business, with each teammate getting their own login and assigned lines.Source ↗
Where it improves on Aissist.io
- +Getting out · PartlyDeletion is immediate and thorough and numbers are released back to the carrier, but no bulk export of calls, transcripts or messages is documented — the read-only connector is the nearest thing to a data-out path.Source ↗
Trade-offs against Aissist.io
- −Claude · NoClaude is supported only as a client that reads your account through the MCP connector; the vendor's own complete list of voice providers for AI calls does not include Anthropic, so Claude does not drive the conversations.Source ↗
- −Free tier · PartlyThere is no standing free plan, which the vendor states outright, but Vera Lite and Vera Plus each open with a 7-day free trial on capped minutes, Vera Business starts paid with no trial, and a browser demo needs no signup.Source ↗
- −Admin controls · PartlyThe owner controls which lines each teammate may touch and keeps billing and business settings to themselves, and can force review of every AI reply — but there is no policy engine beyond those switches.Source ↗
- 02
KalyvoxVerified
AI phone receptionist that answers inbound calls, qualifies them, transfers or books appointments.
From $95/monthWhy it's on this listDone-for-you service · PartlyYou configure and run the software yourself on Solo and Pro, where onboarding is self-service; only the Business plan adds assisted onboarding and a dedicated account manager, and even there the vendor is not running call flows as a service.Source ↗
Where it improves on Aissist.io
- +Agent permissions · YesWhat the assistant may do is bounded by configuration: call reasons, questions, transfer rules and business information you enter, and the vendor publishes deliberate limits including refusing to answer outside that scope or to place outbound calls.Source ↗
- +Seat model · YesSeats are the main plan differentiator with a hard ceiling on the lower tiers: one user on Solo, up to five on Pro, unlimited on Business, and the seat count does not change the per-minute usage rate.Source ↗
Trade-offs against Aissist.io
- −GPT · PartlyThe only model-vendor disclosure anywhere on the site is a sub-processor entry naming OpenAI for voice processing and transcription; there is no plan row, docs page or settings screen that offers GPT as a selectable model, so this is a supply-chain fact rather than a supported-model claim.Source ↗
- −Free tier · PartlyYou can start without talking to sales or entering a card, but only for seven days: there is no standing free plan, and after the trial you either pick a paid plan or the account pauses.Source ↗
- −Admin controls · PartlyAdmins constrain behaviour through roles and permissions, system instructions, transfer rules and the data scope shared with ChatGPT, but the vendor documents no policy engine, approval workflow or spend control.Source ↗
- 03
MixdeskVerified
Omnichannel customer engagement platform with AI Agents for support, sales and lead qualification.
From FreeWhy it's on this listModel choice · PartlyThe built-in AI Agent gives no model picker, but you can route conversations to a Dify or Coze bot you built yourself, including a self-hosted Dify deployment, where the model choice is yours.Source ↗
Where it improves on Aissist.io
- +Bring your own key · PartlyYou cannot supply your own inference key to the native AI Agent, but connecting a Dify or Coze bot means pasting your own provider API key, and a self-hosted Dify also takes your own API URL.Source ↗
- +Getting out · PartlyConversation history and reports export from the workspace and deletion can be requested by email, but exports and API reads reach back only six months, so older history cannot be taken out.Source ↗
Trade-offs against Aissist.io
- −Runs autonomously · PartlyAI Agents reply to customers around the clock without a person present, but they only act once assigned through an automation workflow and the vendor tells you to configure a fallback and human handoff.Source ↗
- −Multi-agent · PartlyYou can run several AI Agents with different roles and route conversations to each, but the docs describe one agent per conversation assignment rather than agents coordinating on one task.Source ↗
- 04
VoiceFleetVerified
Inbound AI phone receptionist for small businesses: answers calls, captures bookings, escalates urgent callers.
From €99/month (about $111)Why it's on this listDone-for-you service · PartlyYou buy and run the software yourself, but the vendor does the initial configuration: setup and onboarding support is a plan row on all three tiers and the pricing page offers founder-led help with greetings, escalation rules and integrations.Source ↗
Where it improves on Aissist.io
- +Getting out · PartlyExport is available during the term and deletion or return happens within about 30 days of termination, but prepaid minute packs and top-ups are non-refundable once applied, so unused balance is lost on exit.Source ↗
Trade-offs against Aissist.io
- −In a browser · PartlyA hosted dashboard is where you configure and review calls, but the analytics dashboard is gated to Growth and Pro and multi-location management to Pro only, so the entry tier gets a thinner web surface.Source ↗
- −Free tier · PartlyThere is a free way in but no standing free plan: every tier carries a 7-day trial with no setup fee, after which a paid plan starting at EUR 99 per month is the only path.Source ↗
- −Admin controls · PartlyConstraint is real but coarse: role-based workspace access and restricted administrative access are documented in the DPA, and the customer controls scripts, booking rules and escalation, yet no granular admin policy console or permission matrix is published.Source ↗
- 05
Cresta
Enterprise contact-centre platform with autonomous voice and digital AI agents plus real-time human agent assist.
Why it's on this listDone-for-you service · PartlyYou buy a subscription, yet Cresta will also build and run the agents for you: builds can be fully managed by its team, with forward-deployed engineers and Implementation Services priced separately on an Order Form.Source ↗
Where it improves on Aissist.io
- +API access · YesCresta states it provides SDKs and APIs for its conversation services, but the reference documentation is gated behind login or a demo request, so endpoints, limits and terms cannot be checked publicly.Source ↗
- +Seat model · PartlyAgent count is one of the quoted pricing inputs and the vendor's stated fit starts around 50 to 100-plus care agents, which works as a practical floor, but no per-seat rate or contractual seat minimum is published.Source ↗
Trade-offs against Aissist.io
- −Claude · PartlyAnthropic is named as a sub-processor supplying natural-language APIs, which is the closest Cresta comes to confirming Claude in its stack; buyers are never offered a named model to select.Source ↗
- −GPT · PartlyOpenAI and Microsoft are named sub-processors supplying natural-language APIs; model choice per task is not published.Source ↗
- −How it meters · PartlyCresta names its pricing dimensions - products, agent count, conversation volume, channels and languages - but publishes no rate, no unit price and no overage figure, so cost is quoted per deployment.Source ↗
- 06
Sierra
Enterprise platform for customer-service AI agents across voice, chat, email and messaging, priced by outcome.
Why it's on this listDone-for-you service · PartlyYou license software and get Sierra's own agent-development team alongside it, so delivery is a partnership rather than pure self-serve tooling.Source ↗
Where it improves on Aissist.io
- +Agent permissions · YesAutonomy is configurable per workflow: you set goals and guardrails and name the steps that require human sign-off before the agent proceeds.Source ↗
- +API access · YesA headless API is one of the published deployment surfaces; the reference is behind the docs sign-in, so endpoints, auth and limits are not public.Source ↗
Trade-offs against Aissist.io
- −Multi-agent · PartlyTwo vendor agents hand work to each other — Explorer's findings go straight to Ghostwriter — but customer-built agents coordinating on one task is not documented publicly.Source ↗
- −Claude · PartlyAnthropic is a named AI-services subprocessor, so Claude is in the mix, but Sierra routes models itself and never exposes a Claude selector.Source ↗
- −GPT · PartlyOpenAI is listed as an AI-services subprocessor, so GPT models are used under the hood, chosen by Sierra's router rather than by the buyer.Source ↗
- 07
AiZipZapVerified
Customer intake agent that turns each request into a job brief, missing questions and a reply draft.
From FreeWhy it's on this listDone-for-you service · PartlyThe product itself is self-serve software, but the parent company separately proposes a scoped two-week business pilot at $750 for one workflow, with consulting never required.Source ↗
Where it improves on Aissist.io
- +Getting out · PartlyReviewed results export as TXT and Markdown and the account can be deleted, but hosted requests are retained only 30 days and unused handoffs expire each billing period.Source ↗
Trade-offs against Aissist.io
- −Runs autonomously · PartlyCollection, saving, drafting and notification run without a human, but the vendor stops deliberately at the draft: the owner reviews, edits and sends every reply themselves.Source ↗
- −Multi-agent · NoOne drafting pass per request is described throughout; the vendor's concurrency statement describes shared generation capacity, not agents coordinating on a task.Source ↗
- −Agent permissions · NoThe agent has no permissions to spend: the vendor lists inbox access, reply sending, code execution and business-system access as things it cannot do at all.Source ↗
- 08
Ada
Agentic customer experience platform running AI support agents across voice, messaging and email.
Why it's on this listDone-for-you service · PartlySoftware you run yourself, but Ada sells a wrapped services layer: ACX Experts give hands-on guidance and ACX Practice supplies blueprints and training, so part of the operating model is delivered by Ada's people.Source ↗
Where it improves on Aissist.io
- +API access · YesA documented REST API suite covers knowledge, end users, conversations and data export, with rotatable keys, versioning, cursor pagination, a downloadable OpenAPI spec and an in-docs playground.Source ↗
- +Bring your own key · PartlyYou bring your own system credentials, not your own inference: MCP and API tools run on company credentials or end-user sign-in you supply, while nothing documents bringing your own model keys or cloud.Source ↗
Trade-offs against Aissist.io
- −Multi-agent · PartlyOne agent per conversation, with several models orchestrated behind a single Reasoning Engine; the vendor describes multi-LLM orchestration and human handoff, not several agents coordinating on one task.Source ↗
- −Free tier · NoThere is no self-serve entry at all: the pricing route resolves to the demo form and the only documented way in is a booked expert session leading to an enterprise agreement.Source ↗
- 09
Fin
Intercom's customer agent that resolves support conversations across chat, email, voice and social channels.
From $0.99/outcomeWhy it's on this listDone-for-you service · PartlyFin is software the buyer configures themselves, and the vendor says no engineering is needed; a paid Deployment Services team will also run the launch, shape knowledge and build Procedures for you.Source ↗
Where it improves on Aissist.io
- +Agent permissions · YesThe buyer sets the boundary: Procedures apply business rules and can require approvals, data access can be restricted to named fields, and Fin escalates rather than answering when confidence thresholds fail.Source ↗
- +Seat model · PartlyFin itself carries no seat cost and the vendor states teammates are unlimited, but the floor is a 50-outcome monthly minimum, and pairing Fin with the Intercom helpdesk adds a per-seat charge for Full seats.Source ↗
Trade-offs against Aissist.io
- −Multi-agent · PartlyTwo agents exist and one acts on the other: Operator tunes, tests and ships changes to Fin, but Operator sits in the paid Pro add-on and its changes are proposals you approve rather than joint work on one customer conversation.Source ↗
- −Claude · PartlyAnthropic is one of the providers Fin falls back to for resilience, but the answer model is Intercom's own Apex and the buyer is not offered a model picker, so Claude is under the hood rather than selectable.Source ↗
- −GPT · PartlyOpenAI models are part of the same automatic failover pool as Anthropic and Google, so GPT is used by the platform but is not a model the customer chooses or configures on any tier.Source ↗
What to watch for
- CrestaFull-platform pricing (AI Agent, Conversation Intelligence, Knowledge Agent) is not published, only the narrower Agent Assist SKU has any public price.
- SierraNo public sign-up, pricing page or self-serve API, access is via an enterprise sales engagement.
- AdaEnterprise, sales-led only. No self-serve signup, no public pricing and no free trial.
- FinWhat counts as a billable "resolution" includes soft outcomes (customer stops replying), which can inflate spend relative to true resolutions.
