Your workspace's audio capabilities just got an upgrade. Voice generation, multilingual dubbing, and music creation are now more realistic and precise.

#What improved

• Realistic voices: More natural-sounding speech for voiceovers, narration, and voice apps.
• Multilingual dubbing: More accurate voice translation across languages, with more natural delivery.
• Music creation: More realistic, natural-sounding music for videos, ads, and other creative projects.

#Put the upgrade to work

Build voice apps, produce ads with voiceovers and music, or create audio for phone systems and automated call flows. Bring the same improvements to product demos, narrated tutorials, and multilingual content.

Better audio, from the first spoken word to the final soundtrack.

27% smarter. 66% cheaper. On average, compared with Kay 1.4.

Kay 1.5 brings a significant intelligence upgrade to Kay, Kay Nano, Kay Pro, and Kay Max, alongside lower prices for all four agents.

#A step up across the board

Browser and computer use have improved significantly across every tier. You should feel the jump in intelligence in everyday work, with agents better equipped to take on longer, more complex tasks.

#How to choose the right Kay tier

Our recommendations remain the same. For the best balance of capability, speed, and credit usage:

• Kay: The recommended default for most tasks.
• Kay Nano: Ideal for time-sensitive work where speed and efficient credit usage matter most.
• Kay Pro: The intelligence sweet spot: near state-of-the-art capability at a significantly lower price than Kay Max. Step up to Pro when Kay is still struggling after a few rounds of work and refinement.
• Kay Max: The absolute highest level of agent intelligence on the market, according to all leading benchmarks. Reserved for the most demanding work, when the highest level of capability justifies higher credit usage, or when another tier cannot make progress.

The same four choices. More intelligence. Lower prices.

Have a full voice conversation with your agent. Speak naturally, hear replies, and keep the work moving without typing every message.

#Same agent. Full capability.

Conversation mode is not a simplified voice assistant. You keep the same agent intelligence, tools, memory, and integrations. Your agent can research, build, use the browser, and carry out tasks while you talk.

#Talk through real work

Explain an idea, ask a follow-up, or discuss the next step out loud. It's a back-and-forth conversation, not just dictation or reading messages aloud.

Only the way you communicate changes, not what your agent can do.

Your agent can now purchase a phone number and make calls on your behalf, handling setup and the conversation end to end. Start with a single call or coordinate a whole fleet of calls from one request.

View your documents, Markdown files, and plans in rich text without leaving the chat, with broad support for graphs, diagrams, tables, code, and more.

Managed APIs give your workspace access to thousands of endpoints across dozens of providers. Ask for the data you need without opening another vendor account or managing another API key.

#Pay for usage, not a full subscription

When a provider charges, you pay only for the successful call with your SPIRITT credits. Free endpoints stay free, failed provider calls are not charged, and automatic routes can choose the lowest-cost compatible provider.

#Data across the work you do

• Sales and enrichment: Find people and companies, enrich records, verify emails, and follow hiring, funding, and news signals.
• Search and growth: Research keywords, search results, backlinks, domain authority, and AI visibility.
• Social and creators: Explore public profiles, content, audiences, trends, and creators.
• Advertising: Research ad libraries and campaign data across major platforms.
• Commerce and reviews: Compare products, listings, prices, and customer sentiment.
• Market data: Pull current and historical stock and crypto data.

The catalog includes familiar providers such as Apollo, Crunchbase, and Semrush, with many more available through the same connection, either free or pay-per-use, so you do not need a separate, expensive subscription for each one.

Four new frontier models are now available in the model picker.

#Choose the right model for the work

• Gemini 3.8 Flash: Fast multimodal work across research, coding, and everyday agents.
• Claude Fable 5.1: Long-running coding, deep codebase research, and complex knowledge work.
• GPT-6 Astra: Computer use, software engineering, and tool-heavy tasks.
• Muse Spark 1.3 Max: Agentic coding, scientific reasoning, and complex workflows.

Each model runs inside a full SPIRITT workspace with browser, terminal, files, memory, and integrations, so you can compare them on real work without changing how you work.

Subscriptions now have a dedicated home in your workspace.

Connect subscriptions you already pay for, then monitor and manage them from one page.

#Connect each account

Add multiple ChatGPT, Claude, or Grok subscriptions. Each account keeps its own credentials and limits, so a new connection never replaces an existing one.

#Monitor and manage

See workspace usage, provider limits, remaining capacity, and reset times. Choose which ChatGPT or Grok account handles new chats, choose the Claude account used by subagents, rename connections, or disconnect them.

A round of UI polish and major bug fixes makes chat, navigation, and everyday work feel smoother and more reliable.

Listen to any completed assistant reply without leaving the conversation.

Select Read aloud beside a message to hear it in a natural voice. Select Stop at any time, or start another message to switch playback.

Search is now built into every workspace.

Use Search to find what you need without retracing your steps, then jump straight back into the relevant work.

Video generation across the workspace is now more capable. Based on Arena benchmarks, it is 50% better than our previous generation.

Create stronger videos from a prompt, source material, or an existing project with our improved state-of-the-art video workflow.

Four new model families are joining the picker.

#Kimi K3, hosted your way

Choose a China-hosted or US-hosted Kimi K3 endpoint based on where you want it to run.

#Meta Muse Spark 1.2

Choose data sharing for a 75% lower price, or keep data sharing off at the regular price.

#DeepSeek V4 and Opus 5

DeepSeek V4 and Opus 5 are available alongside the rest of your models, with the same workspace, tools, and memory.

Pin important messages in chat so decisions, instructions, and useful answers stay easy to reach.

#A clearer Plan UI

Follow the agent's plan as work progresses, with a clearer view of what is active, complete, and still ahead.

#Stable model selection

Your selected model now stays consistent more reliably as you move through the workspace and continue conversations.

This release also brings many smaller UX improvements across the workspace, making everyday work feel smoother and more polished.

Turn a long conversation into a clear, chronological annotation thread without copying, reformatting, or losing your place.

#Keep every excerpt in order

Select text from a message and choose Quote. The excerpt is appended to your current draft without replacing anything you already wrote.

Keep quoting as you move through the conversation. Each excerpt stays in the order you collect it, so you can build a point-by-point response from multiple moments in the thread.

#Add your annotation

After each quote, the cursor is ready for your note. The Markdown-aware composer keeps quotes, headings, lists, emphasis, and code clear while you write.

Connect your existing Grok subscription from the Subscriptions tab.

#Your subscription, enhanced

Sign in securely with your X account, formerly Twitter. Your available Grok models load automatically and stay refreshed, ready to use in the model picker.

You keep using your existing subscription. SPIRITT adds a real workspace, tools, memory, and agent capabilities, so Grok can do more than in the native experience.

Disconnect any time.

Deep Research turns one goal into a coordinated effort that plans, hunts, verifies, and delivers a cited answer.

#The right model mix, automatically

Choose any model or any mixture. By default, SPIRITT automatically assembles the ideal model mix, using each model where it is strongest.

In internal evaluations, it took first place on every publicly known and verified dedicated deep-research benchmark we tested.

#Goal-driven when you choose it

Turn on goal-driven research when the outcome matters more than a fixed depth. It finds the gaps, launches new waves of research, and keeps going until the goal is reached.

#One investigation, every source

Combine the open web, connected integrations, personal accounts, and enterprise systems in a single investigation.

Enterprises uncover hidden insights across huge data estates. Startups find leads across the web and their CRM, then turn research directly into outreach and deals.

Today, we are making SPIRITT integrations much more robust and accessible, with many new integrations, features, and enterprise-level control and visibility.

#Everything visible, everything covered

See every connection, status, authorization, and scope in one place. Use thousands of ready-made and AI-built custom integrations. If something is missing, choose Create with SPIRITT and SPIRITT builds it end to end.

#Personal speed, enterprise control

Connect to one workspace in a click, or let owners and admins authorize access across the organization.

Set action-level rules for Read, Write, and Destructive operations: Always allow, Ask every time, or Never allow. Sensitive actions wait for a time-limited, single-use approval.

#Triggers work both ways

Agents can act inside connected apps, and apps can wake agents with triggers and nudges. A new lead, ticket, payment, calendar event, or deal update can start a durable workflow automatically, protected by the same permissions and approvals.

The workspace now handles complex answers more clearly and feels more polished across everyday interactions.

#A richer chat experience

Diagrams, formulas, highlighted code, complete diffs, and rich links now appear directly in your conversations.

#Polish throughout the workspace

We shipped dozens of small UI fixes and micro-interactions across chat, scrolling, messages, the sidebar, integrations, desktop glass, and onboarding. Together, they make the workspace feel calmer, faster, and more natural to use.

UI polish is a constant process for us. We improve it continuously, and when a wave of changes becomes meaningful enough, we collect it into a changelog update like this one.

Chat now follows the natural direction of every message more closely.

Right-to-left languages such as Arabic, Hebrew, and Persian align as expected, while conversations that mix right-to-left and left-to-right content keep phrases, links, code, numbers, lists, and tables easy to follow. The composer adapts as you type, too, so switching direction feels seamless.

A small UX change with a big benefit for people who work heavily with media.

Tap or click images to open them full screen with their original shape preserved. Videos keep familiar native playback, picture-in-picture, and full-screen controls.

Kay 1.4 is our latest generation of intelligence across every tier. You’ll see stronger reasoning, coding, and long-running agent work, all inside the workspace you already use.

#Existing conversations upgrade automatically

Open an earlier Kay conversation and it continues on the equivalent upgraded tier. Your history, files, tools, and memory remain in place, so there’s nothing to migrate yourself.

#The same range, now more capable

The Kay family still spans quick everyday work through frontier intelligence for the hardest problems. Pick the pace and capability you need; every tier benefits from the upgrade.

#How to choose the right Kay tier

For the best balance of capability, speed, and credit usage, we recommend:

• Kay — the recommended default for most tasks.
• Kay Nano — ideal for time-sensitive work where speed and efficient credit usage matter most.
• Kay Pro — suited to complex tasks that benefit from deeper reasoning.
• Kay Max — reserved for the most demanding work, when the highest level of capability justifies higher credit usage, or when another tier cannot make progress.

Subscription plans are live for workspaces, with new monthly and yearly options built for teams that use SPIRITT regularly.

#Recurring credits

Choose a monthly or yearly plan and your workspace gets a fresh credit allowance every month. Yearly plans include a big discount, paid upfront while credits still refresh monthly so usage stays predictable.

#Top-ups still work

Need extra room before the next refresh? One-time top-ups are still available and now sit clearly below subscription value, so subscriptions are the better default for ongoing work.

#Manage it yourself

Checkout, plan changes, cancellation, reactivation, and billing receipts all stay self-serve from the billing page.

Meta Muse 1.1 is live in the model picker.

We enhance Muse with a real workspace, tools, and memory, so it outperforms the native Muse experience.

Grok 4.5 is available in the model picker.

We enhance Grok with a real workspace, tools, and memory, so it outperforms the native Grok experience.

Long agent tasks now spend less.

The workspace reuses stable context across a task instead of re-paying for the same ground every turn. On real work, that can cut credit use by up to about 60% for the same task.

You get the same quality of work. Your credits just go further.

Connect the AI accounts you already pay for and keep using that same subscription budget here.

#Claude Max

Connect Claude Max from the model picker. Full agent turns, live streaming, history, and a dedicated Subscriptions tab so you can see when it's connected.

#ChatGPT

Connect ChatGPT the same way. Supported models show up across chat modes, with clearer reconnect status when the connection needs a refresh.

Your Claude or ChatGPT budget stays on that account. We enhance them with a real workspace, tools, memory, and end-to-end work, so they outperform their native apps.

The model picker keeps growing. Recent additions include GLM 5.2 Fast, DeepSeek V4 Pro, Kimi K2.7 Code, Gemma 4, Gemini 3.5 Flash, and Claude Opus 4.8.

Every model here is enhanced with a real workspace, tools, and memory, so it outperforms the native experience. Extra models also show short descriptions and brand icons, so choosing one is faster.

Claude Fable is live in the model picker.

We enhance Fable with a real workspace, tools, and memory, so it outperforms the native Claude experience.
