Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of business, basis of presentation and summary of significant accounting policies	1. Nature of business and summary of significant accounting policies Nature of Business Communication Intelligence Corporation and its subsidiary (the "Company" or "CIC") is a leading provider of digital transaction management (DTM) software enabling fully digital (paperless) business processes. The Company's solutions encompass a wide array of functionality and services, including electronic signatures, biometric authentication and simple-to-complex workflow management. These solutions are available across virtually all enterprise, desktop and mobile environments as a seamlessly integrated platform for both ad-hoc and fully automated transactions. The Company's platform can be deployed both on-premise and as a cloud-based service, with the ability to easily transition between deployment models. To date, the Company primarily has delivered its solutions to channel partners and end-user customers in the financial services industry. The Company's products include SignatureOne® Ceremony™ Server, the iSign® suite of products and services, including iSign® Enterprise and iSign® Console™, and Sign-it® programs. Basis of Presentation The financial information contained herein should be read in conjunction with the Company's consolidated audited financial statements and notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2014. The accompanying unaudited condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for complete consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements included in this quarterly report reflect all adjustments (consisting only of normal recurring adjustments) that the Company considers necessary for a fair presentation of its financial position at the dates presented and the Company's results of operations and cash flows for the periods presented. The Company's interim results are not necessarily indicative of the results to be expected for the entire year. Going Concern The accompanying unaudited condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The Company has incurred significant cumulative losses since its inception and, at June 30, 2015, the Company's accumulated deficit was $125,231. The Company has primarily met its working capital needs through the sale of debt and equity securities. As of June 30, 2015, the Company's cash balance was $409. These factors raise substantial doubt about the Company's ability to continue as a going concern. There can be no assurance that the Company will be successful in securing adequate capital resources to fund planned operations or that any additional funds will be available to the Company when needed, or if available, will be available on favorable terms or in amounts required by the Company. If the Company is unable to obtain adequate capital resources to fund operations, it may be required to delay, scale back or eliminate some or all of its operations, which may have a material adverse effect on the Company's business, results of operations and ability to operate as a going concern. The unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Accounting Changes and Recent Accounting Pronouncements Accounting Standards Issued But Not Yet Adopted Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company's financial position, results of operations and cash flows.

Patents	3. Patents The Company performs an intangible asset impairment analysis at least annually or whenever circumstances or events indicate such assets might be impaired. The Company would recognize an impairment charge in the event the net book value of such assets exceeded the future undiscounted cash flows attributable to such assets. Management completed an analysis of the Company's patents as of December 31, 2014. Based on that analysis, the Company concluded that no impairment of the carrying value of the patents existed. The Company believes that no events or circumstances changed during the three and six months ended June 30, 2015 that would impact this conclusion. Amortization of patent costs was $86 and $173 for the three and six-month periods ended June 30, 2015 and $89 and $180 for the three and six-month periods ended June 30, 2014, respectively. The following table summarizes the patents: Amortizable intangible assets: June 30, 2015 December 31, 2014 Carrying Accumulated Net Value Carrying Accumulative Net Value Patents $ 6,745 $ (5,985) $ 760 $ 6,745 $ (5,812) $ 933

Stockholders' Equity [Abstract]
Stockholders' Equity	5. Equity Stock-based compensation expense is based on the estimated grant date fair value of the portion of stock-based payment awards that are ultimately expected to vest during the period. The grant date fair value of stock-based awards to employees and directors is calculated using the Black-Scholes-Merton valuation model. Forfeitures of stock-based payment awards are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The estimated average forfeiture rate for the three months ended June 30, 2015 and 2014, was approximately 7.54% and 9.85%, respectively, based on historical data. Valuation and Expense Information: The weighted-average fair value of stock-based compensation is based on the Black-Scholes-Merton valuation model. Forfeitures are estimated and it is assumed no dividends will be declared. The estimated fair value of stock-based compensation awards to employees is amortized using the accrual method over the vesting period of the options. The fair value calculations are based on the following assumptions: Six Months Ended Six Months Ended Risk free interest rate 0.04% - 3.73% 0.04% - 4.89% Expected life (years) 3.26 - 6.88 3.26 - 7.00 Expected volatility 93.63% - 198.38% 91.99% - 198.38% Expected dividends None None The Company granted 1,000 and 36,633 stock options during the three and six months ended June 30, 2015 at a weighted average exercise price of $0.0224 per share. There were no stock options exercised during the three and six months ended June 30, 2015. The Company granted 2,500 stock options during the three and six months ended June 30, 2014 at a weighted average exercise price of $0.0273 per share. There were no stock options exercised during the three and six months ended June 30, 2014.

Summary of Significant Accounting Policies
Basis of presentation	Basis of Presentation The financial information contained herein should be read in conjunction with the Company's consolidated audited financial statements and notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2014. The accompanying unaudited condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for complete consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements included in this quarterly report reflect all adjustments (consisting only of normal recurring adjustments) that the Company considers necessary for a fair presentation of its financial position at the dates presented and the Company's results of operations and cash flows for the periods presented. The Company's interim results are not necessarily indicative of the results to be expected for the entire year.
Going concern and management plans	Going Concern The accompanying unaudited condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern.
