Supermaven

Generates single-line and multi-line code suggestions in real-time as developers type, using semantic indexing of the entire codebase to retrieve relevant type definitions, function signatures, and contextual patterns. The system maintains a 1M token context window (Pro/Team tiers) that enables suggestions informed by distant code definitions and cross-file dependencies, constructed via local codebase semantic search rather than simple token-based recency. Suggestions adapt to detected coding style on Pro/Team tiers through implicit pattern learning from recent edits.

Provides a separate chat interface supporting multiple LLM backends (GPT-4o, Claude 3.5 Sonnet, GPT-4, others) for conversational code assistance. Users attach files, reference recent edits, and trigger compiler diagnostic uploads; the system generates diffs and applies code changes directly to the editor. Model selection is per-conversation, and $5/month in credits (included in Pro/Team) covers external model API costs; overage pricing is undisclosed. Hotkey-driven workflow enables rapid context switching between inline completion and chat.

Supermaven Chat can automatically upload compiler diagnostic messages (errors, warnings) alongside code context to provide error-aware suggestions and fixes. The mechanism is described as 'automatically uploading your code together with compiler diagnostic messages,' but specific language/compiler support and the upload trigger mechanism are undisclosed. This feature is Chat-only and not available in inline completion.

Supermaven offers a 30-day free trial of the Pro tier ($10/month), providing full access to 1M token context window, largest model, style adaptation, and $5/month chat credits. No credit card is required to start the trial (implied), and trial conversion to paid is automatic after 30 days unless cancelled. Trial terms and auto-renewal policy are not explicitly detailed.

Supermaven requires internet connectivity and server-side inference; no offline mode or local inference capability is mentioned or available. All code completion requests are sent to Supermaven's backend servers for processing, and responses are returned over the network. This creates a hard dependency on network connectivity and Supermaven's service availability; if the service is down or network is unavailable, code completion is not available.

Analyzes recent code edits and inferred coding patterns to adapt inline suggestions to match team conventions, naming patterns, and structural preferences. The mechanism is implicit (not explicit fine-tuning) and operates only on Pro/Team tiers, suggesting pattern learning from editor activity rather than explicit configuration. Free tier uses a single base model without personalization.

Delivers code suggestions to the editor inline as the developer types, with a claimed baseline latency of 250ms from keystroke to suggestion display. The system uses a cloud inference backend and local editor plugin to minimize round-trip time. Latency claim is positioned against an unnamed competitor (783ms), but methodology is undisclosed and no independent verification is provided.

Provides native editor extensions for VS Code, JetBrains IDEs (IntelliJ IDEA, PyCharm, WebStorm, etc.), and Neovim, enabling inline suggestion rendering, hotkey-driven chat access, and compiler diagnostic integration directly within the editor. Each plugin variant is maintained separately and integrates with the editor's native autocomplete UI, keybinding system, and file context APIs.

Supermaven retains code context and conversation data for 7 days across all tiers (free, Pro, Team), then automatically purges it. This policy applies to both inline completion context and chat history. No explicit data export or backup mechanism is mentioned, and no option to extend retention is disclosed.

Supermaven offers a free tier with inline code completion, large codebase support (vaguely defined), and 7-day data retention, but uses a smaller model than Pro/Team and has an undisclosed context window size. The free tier does not include style adaptation, chat credits, or access to the 'largest, most intelligent model' claimed for paid tiers. No explicit feature comparison table is published.

Supermaven Pro ($10/month, 30-day free trial) unlocks the full 1M token context window, access to the 'largest, most intelligent model' for inline completion, style adaptation, and $5/month in chat credits (for external model API costs). Pricing is flat per-user with no per-use overage, and no explicit feature limit is published beyond free tier comparison.

Supermaven Team ($10/month per user) provides the same features as Pro (1M token context, largest model, style adaptation, chat credits) plus centralized user management, centralized billing, and unlimited users per team. Pricing scales linearly with team size (10 users = $100/month, 100 users = $1,000/month). No explicit admin dashboard or team analytics are mentioned.

Supermaven Chat uses a credit-based system where Pro/Team tiers include $5/month in credits to cover external LLM API costs (GPT-4o, Claude 3.5 Sonnet, GPT-4). Credits are consumed per API call to external models; overage pricing is undisclosed. Free tier credit access is unknown. No explicit credit rollover, expiration, or refund policy is mentioned.
