Chatbase is a popular way to build an AI agent from your own content, with a long list of integrations. The catch is how much of it sits behind higher plans and add-ons: one agent per plan, helpdesk features from $150 a month, advanced analytics from $500, and paid top-ups when credits run out. SimplyBoost takes the opposite approach. You pick a plan by the number of AI replies you need, and the channels, agents, handover and lead tools are already in it, for teams of every size, from growing shops to enterprise support desks.
SimplyBoost is a Chatbase alternative where the features come with the plan, not as add-ons. Every plan, from €39 a month, includes 3 AI agents, website chat, WhatsApp and Instagram, handover to Zendesk, Freshdesk, Gorgias or Slack, and lead ratings. Chatbase includes 1 agent per plan and charges $300 a year for each extra one, starts its helpdesk and Zendesk features on Basic at $150, and sells extra message credits at $40 per 1,000.
Our verdict
Choose SimplyBoost if you want the agents, channels and handover inside the plan you already pay for. Three AI agents, WhatsApp, Instagram and handover to Zendesk, Freshdesk, Gorgias or Slack all come with Starter at €39 a month, and none of the plans ever asks you to top up credits.
To be fair
Chatbase still suits teams that want a free plan to experiment with, or need one of its many integrations such as Zapier.

Most teams do this in an afternoon and keep Chatbase running until the answers look right.
Step 1
Add the website pages and files you trained Chatbase on. PDFs, Word files, CSV and images up to 50 MB each all work, and the knowledge base guide lists every source type.
Step 2
Paste your Chatbase instructions into the agent settings, then choose a fixed reply language or let the agent match the customer's language. The agent settings guide explains each option.
Step 3
Connect Slack, Zendesk, Freshdesk or Gorgias and pick the topics that should always reach a person. The handover guide walks you through it.
Step 4
Ask the questions your customers sent most often last month. Anything the agent can't answer shows up under missing answers, so you can add it once.
Step 5
Replace the Chatbase snippet with SimplyBoost's, then connect WhatsApp and Instagram when you're ready.
Plans, limits and yearly prices are on the pricing page. When you're ready, start a 7-day free trial with 100 AI replies.
SimplyBoost works well if leads matter as much as answers. The agent collects name, email, phone and company, scores each lead hot, warm or cold, emails the owner when a new one comes in, and lets you export everything to CSV.
Yes. The same agent answers on your website, WhatsApp and Instagram. Instagram is included on every plan, from Starter at €39 a month.
Yes. Each Chatbase plan includes 1 AI agent, and extra agents cost $25 a month each. Every SimplyBoost plan includes 3 AI agents, and one agent can run on any number of websites.
On Chatbase that needs Standard at $150 a month plus $25 for the second agent, so $175 a month for 4,000 message credits. On SimplyBoost both are included from Starter at €39 a month for 500 AI replies, or Growth at €89 for 2,000.
SimplyBoost costs €39, €89 or €169 a month for 500, 2,000 or 6,000 AI replies. Chatbase Hobby is $40 a month for 700 message credits, Standard is $150 for 4,000 and Pro is $500 for 15,000. Check Chatbase's pricing page for how many credits a message uses in your setup, then compare with your own volume.
