My Assistant features: every function of the AI chat assistant

Can I use my own API key in My Assistant?

Your own API key

Yes. Paste a key from any of 10 AI providers in Settings → Your AI; the app recognises the provider, checks the key once and uses it for your chats.

• Providers: OpenAI, Anthropic (Claude), Google Gemini, DeepSeek, Mistral, xAI (Grok), Groq, OpenRouter, Moonshot (Kimi), SiliconFlow.
• The key is checked with a free "list models" call that uses no AI.
• Keys are stored encrypted (AES-256-GCM) and are ready on all your devices; Settings shows only the last 4 characters.
• Keep several keys and make one active; switch at any time from the top bar (🔑 / 🤖).
• A sensible model is picked from your provider's own list; change it in Settings at any time.
• DeepSeek, OpenRouter, Moonshot and SiliconFlow keys show their balance.
• A key is only ever sent to its own provider.

Can I use My Assistant without an API key?

My Assistant credit

Yes. Buy My Assistant credit and choose "My Assistant" in Settings → Your AI; it answers your chats from your balance.

• PayPal (web and Microsoft Store app): €5, €10, €15 or any amount from €5 to €200.
• Google Play app: €5, €10, €15, €25 or €50.
• Optional automatic top-up (PayPal) when the balance falls below €1.
• €5 covers about 3,700 everyday messages.

• After the last starter chat, a subscription keeps chats going.
• A note near the end of the preview shows how to add a key and what the subscription brings.

How does My Assistant reduce API costs?

Chats that cost less

It sends only the recent part of each chat, sends files once, and keeps the start of every request stable so providers can apply their cache discounts.

• A fixed context budget: long chats never resend their whole history.
• Attached files go with their own message only.
• Code and pages are resent only from the latest reply.
• A stable request prefix lets providers like OpenAI and DeepSeek give up to 90% off repeated input.
• A tip suggests a new chat when a long chat changes topic.
• Example: about 30 messages a day of text chat costs roughly $0.20 to $1.40 a month of API use with light models, plus €1.99.

How do chats work in My Assistant?

Chats

Start a new chat at any time, reopen earlier ones, pin favourites, and remove chats from your list.

• Titles are written by the AI after the 1st, 5th and 15th messages, then every 10 messages.
• Copy, edit or delete your messages; retry, save, report or delete replies.
• Deleted messages are hidden on all your devices and left out of the AI's context, but kept in your exported history.
• A chat removed from the list stays on your device.
