Much more than one answer from many models.

Ask: the Keplar-One answer engine

Every question goes through Keplar-One, the orchestration layer. It is not one model: it decides which models to ask, compares them and writes the final answer.

• Model routing: Classifies each question by kind and difficulty, then asks only the models it needs, weighed by quality, reliability, latency and cost. Free uses free open models; paid plans add premium models from several providers. Plans: Every plan.
• Claim-by-claim comparison: The models answer independently and in parallel, so no answer anchors the others. Keplar breaks the answers into claims and compares them. Plans: Every plan.
• Disagreement map: Shows where the models agree, where they split and why the answer went the way it did. A disagreement is flagged, never silently resolved. Plans: Every plan.
• Evaluation, not voting: A majority is not treated as the truth. Keplar weighs the evidence and reasoning behind each answer, so one dissenting model with the better argument can win. Plans: Every plan.
• Answer breakdown: Under every answer: Consensus (agreement percentage and how many models agreed), Models consulted, Sources the models cite, Disagreements, Verification and a Reasoning summary. Plans: Every plan.
• Reason mode: Works the problem through step by step and shows how the answer was checked. Paid plans add a model to the panel. Plans: Every plan.
• Deep Research: Longer, multi-step research into a report for big decisions. Uses more of your monthly usage. Plans: Plus and Pro.
• Debate mode (Beta): The models argue in rounds and read each other's points before Keplar writes one answer. Uses more usage.
• Voice and Talk (Beta): Ask out loud and hear the answer read back; press and hold to talk. Keplar does not record or store your audio.
• Live demo: Ask a real question on the home page without an account. Plans: No account needed.
• Shared answers: Publish an answer you are proud of to a public page that shows the question, how many models agreed and where they differed. Plans: Signed-in users.
• Web lookups (Coming soon): Live web search inside answers. Shown in the app but not switched on yet. Plans: Paid plans when live.

Files, images and video it can read

Attach the thing you are asking about. Keplar reads it for that question and does not keep the file.

• Images and screenshots: Charts, receipts, whiteboards and interfaces, sent only to models that can see. Plans: Every plan.
• Video: Keyframes are sampled in your browser, so the clip itself is never uploaded. Plans: Every plan.
• Documents, code and data: PDF, text, CSV, JSON and source files, read as text; coding help and file analysis on paid plans. Plans: Every plan.
• Word, PowerPoint, Excel and audio (Coming soon): Office files parsed safely and audio transcribed.
• Links (Coming soon): Paste a URL and Keplar reads the page through a guarded fetch.

Study and present

Tools for learning something and explaining it to others.

• Study mode: Upload a text-based PDF or paste notes and get an outline, a plain-English summary, flashcards with spaced review, quizzes and a day-by-day plan to your exam date. Questions are answered only from your material, with page references, and Keplar says when something is not in it. Plans: Every plan (larger limits and stronger models on paid plans).
• Slideshow maker: Turns a topic, outline or notes into a deck with titles, bullet points, speaker notes and an image idea per slide. Edit it, present it full screen, export to PowerPoint or PDF. Plans: Plus and Pro.
• Guides, docs and a glossary: Plain-English guides on checking AI answers, product docs, a prompt library and an AI glossary. Plans: Public.

Create: websites, apps, images, video and games

Describe what you want, or say it out loud, and Create builds it: it plans a design for the brief, writes the code, tests every screen and publishes it.

• Websites and web apps: Builds full sites and apps from a brief, with a code editor, terminal and live preview side by side. A written design rubric and a lint pass reject the generic AI look (purple glows, gradient blobs, three-card grids) before you see it. Plans: Lite (one small personal site), Plus and Pro.
• Voice Live Create (Beta): Speak and watch the editor, terminal and preview build at the same time; say "actually" to change course. Needs a browser with speech recognition.
• Surprise me: One press picks a specific brief, style and depth and builds it.
• Version history and rollback: Every build is a version. Restore any one, branch it into a new draft, or roll back a change that went wrong.
• Templates and community gallery (Beta): Start from a real site and describe what to change. Sites people chose to share can be liked, remixed and reported.
• Showcase: Demo sites and apps by the Keplar team that set the bar Create is held to.
• Image generation: Make pictures from a message or in the Images studio; attach an image to use as a reference. Plans: Plus and Pro.
• Video generation (Beta): Generate short videos in Create's Video tab. Plans: Pro.
• Mobile apps (Beta): Build mobile app projects in Create's Mobile tab.
• Product import: Paste a product page link and Keplar's fetcher (KeplarBot, which obeys robots.txt) brings in the product details for a page about it. Plans: Signed-in users.

Roblox Studio co-builder

In the Keplar One desktop app, Keplar connects to Roblox Studio through Studio's own tools and builds games with you.

• Builds inside Studio (Beta): Looks at your place first (a screenshot and the Explorer tree), writes a numbered plan, then builds it step by step: maps, buildings, lighting, UI, effects and working Luau scripts, organized in named folders. Plans: Desktop app, signed in.
• Checks its own work (Beta): Takes screenshots after each visible change, reads the output log for errors, play-tests gameplay and fixes what it finds before finishing. Plans: Desktop app.
• Matches references (Beta): Attach screenshots or a clip of a UI, effect or game to match. For effects and UI it reuses Zonito's free particle pack, or makes its own textures in Studio. Plans: Desktop app.
• You stay in control (Beta): Reads run on their own; changes wait for approval unless you turn on auto-approve for safe changes; deleting, publishing, data stores and uploading images to your Roblox account always ask first. Plans: Desktop app.
• Floating overlay (Beta): A movable on-screen panel keeps the build chat next to Studio. Plans: Desktop app.

Collaborate and publish

Work on a project with other people, get a second opinion, and put it online.

• Real-time collaboration: Invite by link and edit the same project together with live cursors, follow mode and a shared terminal and preview.
• AI critic: Rules, accessibility checks in a real browser and a separate model review your build, then apply the fixes you pick.
• One-click publish and previews: Every draft gets a private preview link; publish it to a live keplar.site address in one step.
• Custom domains with HTTPS (Beta): Connect a domain you own; Keplar checks the DNS, tells you what to change and issues certificates. Plans: Plus and Pro.
• Deployments: Every published site and app in one list, with its versions. Plans: Plans with Create.

Agents, projects, memory and connected apps

The parts that make Keplar a workspace you come back to, not a one-off chat.

• Scheduled agents (Beta): Hand off a recurring task: daily briefs, page monitors and lead follow-ups run on the server on a schedule, with run history, pause, resume and run-now. Plans: Plus and Pro (advanced agents on Pro).
• Approvals (Beta): Anything an agent wants to send outside Keplar, such as an email, waits as a draft in Approvals until you approve it. Plans: Plans with agents.
• Projects: Keep related chats, files and work together in a project. Plans: Signed-in users.
• Chat history and memory: Chats are saved to your account to reopen, rename and delete. With memory on, Keplar remembers durable things you tell it (name, goals, preferences) and keeps short summaries of recent chats. Memory is optional and under your control. Plans: Every plan, signed in.
• Specialists: Custom specialists people make and share. Add one to your account and Keplar's panel of models answers with it; shared ones are reviewed before listing. Plans: Signed-in users.
• Connected apps (MCP) (Beta): Connect remote MCP servers such as Context7, DeepWiki, Microsoft Learn and Cloudflare Docs (Linear, Notion and Sentry sign-in in beta). Their tools start off and need approval.
• Keplar Canvas: When you come back signed in, the Canvas home picks up where you left off. Plans: Signed-in users.

Use it from anywhere

The same engine in a desktop app, behind an API and inside a widget on your site.

• Desktop app: For Windows, macOS and Linux. Keeps the app in its own window and adds the Roblox Studio co-builder; your account and data stay in the cloud. Plans: Every plan.
• Public API (Beta): Ask Keplar from your own code with Bearer keys, streaming, an OpenAPI spec and per-plan limits. Free keys use free models only.
• Embeddable widget (Beta): One script tag puts Keplar Ask on your site, limited to the origins you allow.
• Teams (Beta): Shared workspaces with owner, admin, editor and viewer roles.
• Referral program: Invite a friend and you both get extra usage, never cash.
• Languages: The website is published in 25 languages, and you can ask questions in your own language. Plans: Everyone.

Trust and honesty

What Keplar says about itself, and what it does with your data.

• No overclaiming: Keplar is a practical multi-model workspace. It is not AGI or superintelligence, and agreement between models does not prove an answer is correct. Health, legal and money answers are general information, not professional advice. Plans: Everyone.
• Privacy and security: Files you attach are read for that question and not kept; voice is not recorded; a security page explains encryption, providers, retention and how to report a problem. Plans: Everyone.
• Changelog, roadmap and status: Dated release notes, a public roadmap of what is in beta or coming soon, and a live status page. Plans: Public.
