A DeepSeek chat that builds things — free, or unlimited with your own key

2026-08-09 · Tasman Goff · Last updated 2026-09-07

MicroLearnerAI is powered by DeepSeek — the model that proved frontier-class AI doesn't have to cost frontier-class money. That one fact shapes everything about the product: a free tier that's actually usable, a $12 Pro plan, and an Unlimited plan where you bring your own API key and pay us nothing.

Why the model choice matters to your wallet

Most AI apps are priced around the big-name models, whose per-token cost forces tiny free tiers and $20-plus subscriptions. DeepSeek delivers comparable reasoning at a fraction of the per-token price. We pass that straight through: the free tier covers real daily use instead of three demo messages, and Pro is $12 a month rather than the going rate of $20–30.

Cheap doesn't mean weak here. DeepSeek is a serious reasoning model — strong at math, code, and analysis — which is exactly what a chat needs when its whole trick is writing and running code for you mid-conversation.

More than DeepSeek's own chat

If you've used DeepSeek's official chat, you know it's a capable plain chatbot. MicroLearnerAI puts the same class of model inside a tool-using workspace:

The Unlimited API plan: your key, $0 to us

This is the one people double-take on. DeepSeek sells API access directly, at very low per-token prices. On MicroLearnerAI's Unlimited API plan, you paste your own DeepSeek API key into the app, your usage is billed by DeepSeek at their rates — heavy daily use typically costs cents — and MicroLearnerAI charges you nothing. Full tool-using chat, no subscription, no message cap from us.

If you'd rather not touch an API key, that's fine too — the free tier, the $1 Search plan (adds web search), and the $12 Pro plan all work out of the box. The key option just exists for people who use AI hard enough that flat subscriptions stopped making sense.

BYOK, "DeepSeek online", and what the key actually unlocks

BYOK — bring your own key — is the pattern where you supply your own model credentials instead of paying a subscription markup. On most DeepSeek chats, "online" means the hosted web chat with a message limit. Here, BYOK turns the same DeepSeek chat online into an unlimited one: paste your DeepSeek API key once in Settings, and the full tool-using chat — code execution, connectors, browser use, agent loops — runs against your own DeepSeek account at their per-token rates, with no ceiling from us. If you already have a DeepSeek API key, that's the plan to pick.

FAQ

Is this the real DeepSeek model?

Yes. MicroLearnerAI runs on DeepSeek's models — the same frontier-class reasoning the AI world made a fuss about — wrapped in a chat that can also execute code, use connectors, and run scheduled tasks. On the Unlimited API plan you connect your own DeepSeek API key, so the model calls go through your own account directly.

What does "bring your own key" mean?

DeepSeek sells API access directly at very low per-token prices. On MicroLearnerAI's Unlimited API plan ($0), you paste in your own DeepSeek API key and your usage is billed by DeepSeek at their rates — typically cents for heavy daily use — while MicroLearnerAI charges nothing. You get the full tool-using chat without a subscription.

How is this different from DeepSeek's own chat?

DeepSeek's official chat is a good plain chatbot. MicroLearnerAI turns the same model into a working tool: it writes and runs code mid-conversation (real spreadsheets, decks, charts, apps), connects to Gmail, Drive, Calendar, Slack, Notion and thousands of other apps, and runs scheduled agent loops on our servers while you're offline.

How much does it cost if I don't bring my own key?

There's a free tier that covers normal use, a $1 Search plan that adds web search, and a $12/month Pro plan for heavier daily workloads. Because DeepSeek's per-token cost is a fraction of the big-name models, the free tier can be genuinely usable instead of a three-message demo.

Is there a free DeepSeek chat online?

Yes. Signing up gives you a free DeepSeek chat online with no credit card, and the free tier resets on a schedule instead of stopping after a few messages. Prefer to control your own billing? The BYOK Unlimited API plan lets you bring your own DeepSeek API key and pay DeepSeek directly.

Try the free tier at MicroLearnerAI chat — and if you already have a DeepSeek key, you know which plan to pick.
