Cumbersome Changelog

What changed

Long running tools on compatible MCP servers can continue as recoverable tasks while you keep chatting. This release also adds optional Responses compatibility for custom providers, callable phone numbers, faster sidebar search, and fixes for images, tool history, redirects, and older MCP servers.

What changed

Project files keep their imported names when edited, and valid filenames work correctly in release builds. MCP connection errors and support for server input requests are explained more clearly.

What changed

MCP servers can ask for structured input in the conversation, retain structured results, and update their available tools while connected. You can send images or files without accompanying text. This release also improves iCloud sidebar updates, iPhone composer layout, background progress, and launching on macOS Sequoia.

What changed

Cumbersome Pro adds editable Project files with previews, version history, draft recovery, and review before later AI changes to existing files are applied. You can keep an Incognito conversation in Timeline, preview source files with syntax highlighting, and add values to existing API parameter arrays. Long chats and wide tables are smoother to use.

What changed

Open separate conversations in independent iPad windows. Deleting a Project from the sidebar now preserves its chats, while fixes stabilize attachments, tool history, background responses, and model temperature defaults.

What changed

Turn off Cumbersome usage analytics from Settings and sync that choice through iCloud. You can also hear replies as they arrive and choose Save and Restart when editing a message. This release fixes several attachment, custom-provider, and chat issues.

What changed

Copy and export actions are grouped by conversation, while Compact and Ghost/Write live in the conversation title menu. Message menus are simpler, with further improvements to streaming and composer layout.

What changed

OpenCode Go connections now send the session information the service requires. OpenRouter requests keep a stable conversation session, and sidebar selection controls are more consistent.

What changed

Select multiple conversations to organize or delete them together, and export or import your full conversation collection on Mac. Custom providers support more local HTTP endpoints, and reasoning settings carry through to Face/Off, Mind/Meld, and Ghost/Write.

What changed

AI responses can continue when Cumbersome moves to the background on iOS 26. This release also added B&W and Terminal themes, multiple authentication headers for custom providers, and native Question Cards for structured clarification.

What changed

Web Agent keeps one visible browser attached to the active chat for multi-step work. You can watch the page, take over when needed, and hand the same page state back to the model. Folders are now projects, OpenRouter presets appear in the model picker, and provider connections can be reordered.

What changed

Take a photo from the composer, see cumulative API tokens in Message Details, and set the fallback order for local search engines.

What changed

Local Web Browser can run one JavaScript action before extracting a page, which helps when a simple interaction reveals the useful content. Cumbersome also gained on-device PDF text extraction and Copy Chat.

What changed

You can highlight a passage in any completed message, attach a note, and include it with your next reply without rewriting the original. Cumbersome can also read replies aloud and turn Mermaid code into diagrams automatically.

What changed

Cumbersome can analyze CSV, TSV, JSON, and text attachments with Python on your device, then return tables and charts. The same version added Markdown export, Mermaid diagrams, request details, and one-tap code copying.

What changed

Google AI Studio conversations can send video files, while compatible custom AI servers can use OpenAI's newer Responses API. Cumbersome can also tell the AI the current date automatically.

What changed

Independent local browser and remote MCP tool calls can now run at the same time, helping research and other tool-heavy requests finish faster.

What changed

For difficult prompts, Mind/Meld can ask three independent AI tracks, then use another AI to combine the strongest ideas into one answer. Conversation controls and navigation also received a broad redesign.

What changed

Cumbersome is now fully available in Simplified Chinese. New sensitive conversation data also receives added iCloud encryption, alongside a broad pass on chat performance and Mac controls.

What changed

Ghost/Write uses the conversation so far to draft a pointed observation and follow-up question as your next turn, clearly marked as AI-written. Mac users can also import conversations from JSON backups.

What changed

You can connect remote MCP servers, choose their tools, and let the AI use them inside a conversation. New diagnostics also make long-response performance easier to inspect.

What changed

Choose a visual theme and reading font to make Cumbersome fit how you prefer to work.

What changed

Folders can carry their own reusable system instructions, so every chat inside a folder can start with the same guidance.

What changed

Anthropic prompt caching can be controlled from Settings, and supported providers now show cache usage so you can see when repeated context is being reused.

What changed

Save reusable system instructions and apply them to individual conversations instead of rewriting the same guidance each time.

What changed

Compact summarizes older history for future requests while leaving the original transcript visible, which can reduce repeated context and API cost.

What changed

Run HTML and JavaScript code blocks in an isolated in-app preview instead of copying them into another tool.

What changed

Organize conversations into synced folders, then move and group chats without losing the familiar date-based history.

What changed

Conversation sections in the sidebar can be collapsed, and that choice syncs across devices.

What changed

Generate images with supported OpenAI and Google AI Studio connections, and watch partial previews appear while an image is still being created. The transcript was also rebuilt to handle long chats more smoothly.

What changed

Local search and browsing tools now work through OpenAI, Anthropic, Google AI Studio, Z.ai, and compatible gateways. Search and page browsing can be switched on separately.

Add Cumbersome to the iPhone Lock Screen for quick access, set old conversations to delete automatically, and use the document-style transcript everywhere.

What changed

Cumbersome gained local browser tools, letting supported AI connections search the web and open pages through your device. Reasoning support also expanded across more providers.

What changed

Connect your own OpenAI-compatible service, including local or hosted endpoints, fetch its model list, and use attachments without waiting for a built-in provider integration.

What changed

Paste images straight into chat, preview attachments before sending, and use include filters to tame large model lists. Web search can also wait until you explicitly ask for it.

What changed

OpenAI and OpenRouter conversations can show collapsible reasoning while a response streams, making the model's returned thinking easier to inspect.

What changed

OpenRouter joined the provider list, giving you one API connection for models from multiple AI companies while keeping Cumbersome's model and parameter controls.

What changed

Multiple conversations can now generate replies at the same time. You can also queue another message while a response is running, and stopping a reply preserves the partial answer.
